Description
本発明は透明導電性フィルムとして好適に用いることが可能な積層体に関する。特に、2層以上の金属層を積層した透明導電性フィルムに好適に適用が可能な積層体に関するものである。 The present invention relates to a laminate that can be suitably used as a transparent conductive film. In particular, the present invention relates to a laminate that can be suitably applied to a transparent conductive film in which two or more metal layers are laminated.
静電容量式のタッチパネルはマルチタッチが可能であり、西日や落ち葉、虫などにも誤作動せず屋外利用できることから利用が増加している。 Capacitive touch panels are capable of multi-touch and are increasingly used because they can be used outdoors without malfunctioning against the sun, fallen leaves, and insects.
静電容量式のタッチパネルは、特定の電極パターンを形成し電極間の静電容量値の変化を検出して、押圧した位置を特定する構造となっている。この静電容量式の1つの方式は、2面の電極をパターン化し、コントローラーにて押圧位置の微弱な電流を電圧に変換して検出しようとするものである。従って静電容量式のタッチパネルに使用される導電性フィルムは、表面抵抗率が小さくかつ透明性の高いものが要求される。 The capacitance type touch panel has a structure in which a specific electrode pattern is formed, a change in capacitance value between the electrodes is detected, and a pressed position is specified. One method of this capacitance type is to pattern two electrodes and convert a weak current at the pressed position into a voltage by a controller to detect the voltage. Therefore, the conductive film used for the capacitive touch panel is required to have a low surface resistivity and high transparency.
従来、抵抗膜式または静電容量式の導電性基板材料として、ITO膜(Indium Tin Oxide)を表面に形成させたフィルムが広く使用されている。このITO膜は、フィルムの表面に蒸着法やスパッタリング法により形成され、そのため大型化はコスト面で制約されることが問題であった。またITO膜は、体積抵抗率が比較的高いという問題もある。体積抵抗率が高ければ大型の電極パターンを形成した際に抵抗値も高くなり、押圧位置の微弱な電流の検出が困難になる。ITO膜電極の抵抗値を低くしようとすれば、膜厚を厚くすればよいが、膜厚の増加は透明性の低下および屈曲性の低下をきすので好ましくない。 2. Description of the Related Art Conventionally, a film having an ITO film (Indium Tin Oxide) formed on the surface has been widely used as a resistance film type or capacitance type conductive substrate material. This ITO film is formed on the surface of the film by a vapor deposition method or a sputtering method, so that the increase in size is a problem in terms of cost. The ITO film also has a problem that the volume resistivity is relatively high. If the volume resistivity is high, the resistance value also becomes high when a large electrode pattern is formed, and it becomes difficult to detect a weak current at the pressed position. If the resistance value of the ITO film electrode is to be lowered, the film thickness may be increased. However, an increase in the film thickness is not preferable because it causes a decrease in transparency and a decrease in flexibility.
近年、基材の片面の表面に、導電性金属の微細線の多数が並行して一方向に配列して形成された透明複合基板であって、この透明複合基板の2枚を、金属の微細線が配列された面が互いに向い合い且つ金属の微細線の配列方向が直交するように絶縁性接着剤を介して重ね合せ、一方の透明複合基板を上部基板層とし他方の透明複合基板を下部基板層として構成する静電容量式タッチパネルが提案された(特許文献1)。この静電容量式タッチパネルの透明導電性フィルムは前述の電極パターンの抵抗値が極めて低く、透明性と屈曲性に優れるものである。 2. Description of the Related Art In recent years, a transparent composite substrate in which a large number of fine lines of conductive metal are arranged in one direction in parallel on the surface of one side of a base material. Overlay each other with an insulating adhesive so that the planes on which the lines are arranged face each other and the arrangement direction of the metal fine lines is orthogonal, one transparent composite substrate as the upper substrate layer and the other transparent composite substrate as the lower portion A capacitive touch panel configured as a substrate layer has been proposed (Patent Document 1). The transparent conductive film of this capacitive touch panel has an extremely low resistance value of the electrode pattern described above, and is excellent in transparency and flexibility.
しかしながら、この透明導電性フィルムは配線部が金属光沢を有しており、その反射光によってタッチパネルの下に配されるディスプレイの視認性が低下するという課題がある。 However, the transparent conductive film has a problem that the wiring portion has a metallic luster, and the visibility of the display disposed under the touch panel is lowered by the reflected light.
また、ストライプ状配線を2〜20本束にして電極としているが、キズやピンホールによる断線に対する冗長性が不十分となることがある。冗長性を確保するにはストライプ状配線に更に横串を通してメッシュ状にすることが効果的であるが、その場合2枚のフィルムの貼り合わせ位置や貼り合わせ角度がずれるとモアレを生じやすい課題がある。 Further, although 2 to 20 striped wirings are bundled to form an electrode, redundancy with respect to disconnection due to scratches or pinholes may be insufficient. In order to ensure redundancy, it is effective to make a mesh shape by passing a horizontal skewer on the striped wiring. In that case, however, there is a problem that moire is likely to occur if the bonding position and the bonding angle of the two films are shifted. is there.
本発明は上記のような事情を鑑みてなされたものであり、配線部の金属光沢反射光によりタッチパネル下に配置されるディスプレイの視認性を低下することなく、メッシュ状としても2枚のフィルムの貼り合わせのズレが生じない透明導電性フィルムに適用することが可能な積層体を提供することを目的とする。 The present invention has been made in view of the circumstances as described above, and without reducing the visibility of the display arranged under the touch panel by the metallic gloss reflected light of the wiring portion, the two films can be formed as a mesh. It is an object of the present invention to provide a laminate that can be applied to a transparent conductive film that does not cause misalignment.

さらに、黒化層などがパターン状の積層体の場合には、それぞれの層は、同じサイズ、形状のパターンである必要はなく、各層は独立してパターンのサイズ、形状を選択することが可能である。黒化層などがパターン状の積層体であり、基材の両側に前述する何らかの層を有する積層体の場合、基材の一方の側の各層は、サイズ、形状が同一のパターンであり、基材の他の側の各層も、サイズ、形状が同一のパターンであり、基材の一方の側の各層のパターンと他の側の各層のパターンとが、形状若しくはサイズが異なることが好ましい。
本発明の積層体は、少なくとも黒化層を2層と基材を1層有しさえすれば、各層の積層順序は特に限定されないが、後述する本発明の第一実施の形態の積層体は、黒化層(以下、黒化層A1という)、金属層(以下、金属層A1という)、基材、黒化層(以下、黒化層A2という)、金属層(以下、金属層A2という)を、この順に有することが好ましい。本発明の第一実施の形態の積層体が、このような積層構成であることにより、本発明の積層体を透明導電性フィルム用途に用いた場合に、タッチパネル下に配置されるディスプレイの視認性を低下させることなく、また配線をメッシュ状にして断線に対する冗長性を増してもモアレを生じにくい効果を有する。
Furthermore, when the blackened layer or the like is a patterned laminate, each layer need not be the same size and shape pattern, and each layer can be independently selected for the pattern size and shape. It is. In the case of a laminate in which the blackened layer or the like is a patterned laminate and has any of the layers described above on both sides of the substrate, each layer on one side of the substrate is a pattern having the same size and shape. Each layer on the other side of the material also has the same size and shape, and the pattern of each layer on one side of the substrate and the pattern of each layer on the other side are preferably different in shape or size.
As long as the laminate of the present invention has at least two blackening layers and one substrate, the stacking order of each layer is not particularly limited, but the laminate of the first embodiment of the present invention described later is , Blackened layer (hereinafter referred to as blackened layer A1), metal layer (hereinafter referred to as metal layer A1), substrate, blackened layer (hereinafter referred to as blackened layer A2), metal layer (hereinafter referred to as metal layer A2) ) In this order. When the laminate of the first embodiment of the present invention has such a laminate configuration, when the laminate of the present invention is used for a transparent conductive film, the visibility of the display placed under the touch panel is visible. Even if the wiring is meshed and the redundancy against disconnection is increased, moire is less likely to occur.
本発明の第一実施の形態の積層体は、金属層A1と基材の間に、密着層(以下、密着層A1という)を有し、さらに、基材と黒化層A2の間に密着層(以下、密着層A2という)を有する態様がより好ましい。密着層を有することで、エッチングや保護フィルム剥離などの後工程において、金属層などが剥がれるのを防止することができる。 The laminate according to the first embodiment of the present invention has an adhesion layer (hereinafter referred to as adhesion layer A1) between the metal layer A1 and the base material, and further adheres between the base material and the blackening layer A2. The aspect which has a layer (henceforth adhesion layer A2) is more preferable. By having the adhesion layer, it is possible to prevent the metal layer or the like from being peeled off in a subsequent process such as etching or protective film peeling.
以下、この第一実施の形態を含む本発明を、その実施の形態を示す図面を参照して具体的に説明する。 Hereinafter, the present invention including the first embodiment will be described in detail with reference to the drawings showing the embodiment.
[第一実施の形態]
図1は本発明の第一実施の形態による積層体の構成を示す概略図である。つまり、本発明の第一実施の形態による積層体は、黒化層A1、金属層A1、基材、黒化層A2、金属層A2を、この順に有する。そしてより好ましい本発明の第一実施の形態による積層体は、金属層A1と基材の間に、密着層A1を有し、さらに、基材と黒化層A2の間に密着層A2を有する、つまり、黒化層A1、金属層A1、密着層A1、基材、密着層A2、黒化層A2、金属層A2を、この順に有する。
[First embodiment]
FIG. 1 is a schematic view showing the configuration of the laminate according to the first embodiment of the present invention. That is, the laminated body by 1st embodiment of this invention has the blackening layer A1, metal layer A1, a base material, blackening layer A2, and metal layer A2 in this order. And the more preferable laminated body by 1st embodiment of this invention has adhesion layer A1 between metal layer A1 and a base material, and also has adhesion layer A2 between base material and blackening layer A2. That is, it has the blackening layer A1, the metal layer A1, the adhesion layer A1, the substrate, the adhesion layer A2, the blackening layer A2, and the metal layer A2 in this order.
黒化層A1、金属層A1、密着層A1、基材、密着層A2、黒化層A2、金属層A2がベタ膜からなる本発明の積層体においては、黒化層、金属層、及び密着層を部分的に除去して、パターン状の黒化層、金属層、及び密着層とすることで、タッチセンサーの電極として好適に用いることができる。なお、この場合、黒化層A1側から見て使用することが好ましい(つまり、黒化層A1が視認側である。)。 In the laminate of the present invention in which the blackening layer A1, the metal layer A1, the adhesion layer A1, the substrate, the adhesion layer A2, the blackening layer A2, and the metal layer A2 are solid films, the blackening layer, the metal layer, and the adhesion layer By partially removing the layer to form a patterned blackening layer, a metal layer, and an adhesion layer, it can be suitably used as an electrode of a touch sensor. In this case, it is preferable to use it as viewed from the blackened layer A1 side (that is, the blackened layer A1 is on the viewing side).
以下、この態様等について詳細を説明する。 Hereinafter, this aspect etc. will be described in detail.
基材(3)を構成する材料は、特に限定されず、コストや入手容易性の観点からガラスや樹脂が好適である。基材を構成する材料としてガラスを選択した場合、ガラスは樹脂に比べてヘイズが低いために、タッチセンサー下のディスプレイの画像がクリアに見える特徴がある。また、基材を構成する材料として、樹脂を選択した場合、樹脂は可撓性を有し曲面に適用できるタッチセンサーを作製することができる特徴を有する。基材を構成する材料として樹脂を選択した場合、基材をフィルムと呼ぶことがある。 The material which comprises a base material (3) is not specifically limited, Glass and resin are suitable from a viewpoint of cost or availability. When glass is selected as the material constituting the substrate, glass has a feature that the image on the display under the touch sensor can be seen clearly because the haze is lower than that of the resin. In addition, when a resin is selected as a material constituting the base material, the resin has a characteristic that a flexible touch sensor that can be applied to a curved surface can be manufactured. When a resin is selected as the material constituting the base material, the base material may be referred to as a film.
また、基材がフィルムの場合には、ロール状態での入手が容易であるためロールトゥロールでの加工が可能となり、生産性に優れる特徴もある。フィルムを構成する樹脂としては、特に限定されないが、PET(ポリエチレンテレフタレート)やPEN(ポリエチレンナフタレート)、ポリアラミド、ポリイミド、ポリカーボネート、ポリエチレン、ポリプロピレンなどを用いることができる。 In addition, when the substrate is a film, since it is easily available in a roll state, it can be processed by a roll-to-roll, and has a feature of excellent productivity. Although it does not specifically limit as resin which comprises a film, PET (polyethylene terephthalate), PEN (polyethylene naphthalate), polyaramid, a polyimide, a polycarbonate, polyethylene, a polypropylene, etc. can be used.
また基材(3)は、透明性を有することが好ましい。基材は、好ましくは全光線透過率が20%以上であり、より好ましくは全光線透過率が50%以上である。基材の全光線透過率は、高ければ高いほどよいが、99%を超えることが困難なので、現実的な上限は99%程度である。 Moreover, it is preferable that a base material (3) has transparency. The substrate preferably has a total light transmittance of 20% or more, more preferably a total light transmittance of 50% or more. The higher the total light transmittance of the substrate, the better. However, since it is difficult to exceed 99%, the practical upper limit is about 99%.
本発明の積層体(1)は、黒化層、金属層、及び密着層を部分的に除去してパターン状の黒化層、金属層、及び密着層とすることで、タッチセンサーの電極とすることができるが、その場合に基材が導電性を有すると、電極間が短絡してしまう問題が生じることがある。そのため基材は絶縁性であることが好ましい。 The layered product (1) of the present invention can be obtained by partially removing the blackening layer, the metal layer, and the adhesion layer to form a patterned blackening layer, metal layer, and adhesion layer. However, if the base material is conductive in that case, there may be a problem that the electrodes are short-circuited. Therefore, the base material is preferably insulating.
基材(3)の厚みは特に限定されるものではないが、好ましくは1μm以上5000μm以下であり、より好ましくは10μm以上500μm以下であり、更に好ましくは20μm以上250μmである。基材が薄すぎるとハンドリングが困難となることがあり、厚すぎると透明性が損なわれてしまうことがある。
黒化層は、窒化銅、酸化銅、窒化ニッケル、及び酸化ニッケルからなる群より選ばれる少なくとも1つを含む層である。黒化層は、層の全体100原子%において、銅およびニッケルの合計含有量(原子数基準)が50原子%以上95原子%以下の層であり、かつ窒素および酸素の合計含有量(原子数基準)が5原子%以上50原子%以下の層であることが好ましい。この原子数の確認は、Ar+イオンによる積層体のエッチング(条件:加速電圧2kV、試料傾斜角度30°)とオージェ電子分光法(条件:加速電圧10kV、試料電流20nA、試料傾斜角30°)によって可能である。窒素および酸素の合計含有量が5原子%より小さいと黒化層が金属光沢を有し黒化機能が不足することがあり、50原子%より多い黒化層は作製することが困難である。
Although the thickness of a base material (3) is not specifically limited, Preferably it is 1 micrometer or more and 5000 micrometers or less, More preferably, they are 10 micrometers or more and 500 micrometers or less, More preferably, they are 20 micrometers or more and 250 micrometers. If the substrate is too thin, handling may be difficult, and if it is too thick, the transparency may be impaired.
The blackening layer is a layer including at least one selected from the group consisting of copper nitride, copper oxide, nickel nitride, and nickel oxide. The blackening layer is a layer in which the total content of copper and nickel (on the basis of the number of atoms) is 50 atomic% or more and 95 atomic% or less, and the total content of nitrogen and oxygen (number of atoms) It is preferable that the layer is a layer of 5 atomic% to 50 atomic%. The number of atoms is confirmed by etching the laminate with Ar + ions (conditions: acceleration voltage 2 kV, sample tilt angle 30 °) and Auger electron spectroscopy (conditions: acceleration voltage 10 kV, sample current 20 nA, sample tilt angle 30 °). Is possible. If the total content of nitrogen and oxygen is less than 5 atomic%, the blackened layer may have a metallic luster and the blackening function may be insufficient, and it is difficult to produce a blackened layer having more than 50 atomic%.
黒化層A1は、視認側(図1でいう上側)から見て金属層A1(4a)を覆うように存在している。このようにすることで、金属層A1(4a)が金属光沢を持つ場合や有彩色である場合に、金属層A1の表面反射によりディスプレイに写される像のコントラストが低下するのを防ぐ効果がある。 The blackening layer A1 exists so as to cover the metal layer A1 (4a) when viewed from the viewing side (the upper side in FIG. 1). By doing in this way, when the metal layer A1 (4a) has a metallic luster or a chromatic color, the effect of preventing the contrast of the image projected on the display from being lowered by the surface reflection of the metal layer A1 is prevented. is there.
黒化層の形成方法は特に限定されず、例えば、スパッタリング法やメッキ法によって形成することができる。 The formation method of a blackening layer is not specifically limited, For example, it can form by sputtering method and the plating method.
黒化層の厚みは特に限定されないが、5nm以上200,000nm以下が好ましく、10nm以上1,000nm以下がより好ましい。黒化層A1の厚みが5nm以下の場合には、黒化層A1を透過する光が多くなり前述の効果を十分に発揮できないことがある。黒化層A1の厚みが200,000nmを超えると、黒化層A1を部分的に除去した際に黒化層A1の側面が透過光を遮って、そのような本発明の積層体をタッチパネルに用いた場合には、タッチパネルの視野角が制限されることがある。 Although the thickness of a blackening layer is not specifically limited, 5 nm or more and 200,000 nm or less are preferable, and 10 nm or more and 1,000 nm or less are more preferable. When the thickness of the blackened layer A1 is 5 nm or less, the amount of light transmitted through the blackened layer A1 may increase and the above-described effects may not be sufficiently exhibited. When the thickness of the blackened layer A1 exceeds 200,000 nm, the side surface of the blackened layer A1 blocks the transmitted light when the blackened layer A1 is partially removed, and such a laminate of the present invention is applied to the touch panel. When used, the viewing angle of the touch panel may be limited.
黒化層A2(2b)は、視認側(図1でいう上側)から見て金属層A2(4b)を覆うように存在している。黒化層A2を用いる目的や好ましい様態については黒化層A1と同様である。
金属層は、チタン、ニッケル、クロム以外の金属からなる層である。そのため金属層は、積層体(1)に導電機能を付与することができる。黒化層A1(2a)や密着層A1(5a)が導電性を有する場合には、金属層A1(4a)によって導電機能を付与することは必ずしも必要ではないが、導電性に優れた金属層A1を設ける方が、黒化層A1や密着層A1によって導電機能を兼ねるよりも、金属層A1と黒化層A1と密着層A1の合計の厚みを薄くすることができ、好適である。
The blackening layer A2 (2b) is present so as to cover the metal layer A2 (4b) when viewed from the viewing side (the upper side in FIG. 1). The purpose and preferred mode of using the blackened layer A2 are the same as those of the blackened layer A1.
A metal layer is a layer which consists of metals other than titanium, nickel, and chromium. Therefore, the metal layer can impart a conductive function to the laminate (1). When the blackening layer A1 (2a) or the adhesion layer A1 (5a) has conductivity, it is not always necessary to provide the conductive function with the metal layer A1 (4a), but the metal layer with excellent conductivity. Providing A1 is preferable because the total thickness of the metal layer A1, the blackening layer A1, and the adhesion layer A1 can be reduced, rather than having the conductive function by the blackening layer A1 and the adhesion layer A1.
金属層は、チタン、ニッケル、クロム以外の金属を含みさえすれば特に限定されないが、金、銀、銅、アルミニウム、マグネシウム、タングステン、コバルト、亜鉛、及び鉄からなる群より選ばれる少なくとも1種以上の金属を含むことが好ましい。高い導電性を付与する観点から、金属層は、金、銀、銅、及びアルミニウムからなる群より選ばれる少なくとも1つの金属から構成されることがより好適であり、コストとのバランスを考えると金属層は銅であることがより好適である。 The metal layer is not particularly limited as long as it contains a metal other than titanium, nickel, and chromium, but at least one selected from the group consisting of gold, silver, copper, aluminum, magnesium, tungsten, cobalt, zinc, and iron It is preferable to contain these metals. From the viewpoint of imparting high electrical conductivity, the metal layer is more preferably composed of at least one metal selected from the group consisting of gold, silver, copper, and aluminum. More preferably, the layer is copper.
なお金属層は、層の全体100原子%において、チタン、ニッケル、クロム以外の金属の合計含有量(原子数基準)が50原子%以上100原子%以下の層であることがより好ましく、さらに好ましくは95原子%以上100原子%以下の層である。 The metal layer is more preferably a layer having a total content of metals other than titanium, nickel, and chromium (based on the number of atoms) of 50 atomic% or more and 100 atomic% or less in 100 atomic% of the entire layer. Is a layer of 95 atomic% or more and 100 atomic% or less.
また金属層は、酸素や窒素、炭素といった非金属を含有していてもよいが、層の全体100原子%における非金属の合計含有量(原子数基準)は、5原子%以下であることが好ましい。金属層中の非金属の合計含有量が5原子%を超えると、導電性が十分に得られないことがある。 The metal layer may contain non-metals such as oxygen, nitrogen, and carbon, but the total content of non-metals (based on the number of atoms) in the whole 100 atomic% of the layer is 5 atomic% or less. preferable. When the total content of non-metals in the metal layer exceeds 5 atomic%, sufficient conductivity may not be obtained.
これらの原子数の確認は、前述の条件によるエッチングとオージェ電子分光法によって可能である。 The number of these atoms can be confirmed by etching and Auger electron spectroscopy under the above-mentioned conditions.
金属層の形成方法は特に限定されず、選択される金属層の素材に応じて適宜形成方法を選ぶことができる。例えば、金属層が銅の場合には、金属層は真空蒸着法やスパッタリング法によって形成することができる。 The formation method of a metal layer is not specifically limited, According to the raw material of the metal layer selected, a formation method can be selected suitably. For example, when the metal layer is copper, the metal layer can be formed by a vacuum deposition method or a sputtering method.
金属層の厚みは、10nm以上200,000nm以下が好適であり、100nm以上15,000nm以下がより好適であり、300nm以上3,000nm以下が更により好適である。金属層の厚みが10nmよりも薄いと十分な導電性が得られないことがあり、200,000nmを超えると、金属層を部分的に除去した際に金属層A1の側面が透過光を遮って、そのような本発明の積層体をタッチパネルに用いた場合には、タッチパネルの視野角が制限されることがある。 The thickness of the metal layer is preferably from 10 nm to 200,000 nm, more preferably from 100 nm to 15,000 nm, and even more preferably from 300 nm to 3,000 nm. If the thickness of the metal layer is less than 10 nm, sufficient conductivity may not be obtained. If the thickness exceeds 200,000 nm, the side surface of the metal layer A1 blocks the transmitted light when the metal layer is partially removed. When such a laminate of the present invention is used for a touch panel, the viewing angle of the touch panel may be limited.
金属層A2(4b)を用いる目的や好ましい様態については金属層A1(4a)と同様である。
第一実施の形態の積層体(1)は、金属層A1(4a)と基材(3)との間に、密着層A1(5a)を有することが好ましい。密着層A1(5a)を設ける理由は、エッチングや保護フィルム剥離などの後工程で、金属層A1と基材が剥がれるのを防止することである。
The purpose and preferred mode of using the metal layer A2 (4b) are the same as those of the metal layer A1 (4a).
The laminate (1) of the first embodiment preferably has an adhesion layer A1 (5a) between the metal layer A1 (4a) and the base material (3). The reason for providing the adhesion layer A1 (5a) is to prevent the metal layer A1 and the substrate from being peeled off in a subsequent process such as etching or peeling of the protective film.
本発明でいう密着層は、チタン、ニッケル、及びクロムからなる群より選ばれる少なくとも1つの元素を含む層である。密着層は、黒化層と別の層(基材など)との間に存在して、これらの層間の密着性を向上する機能を有する層である。 The adhesion layer referred to in the present invention is a layer containing at least one element selected from the group consisting of titanium, nickel, and chromium. An adhesion layer is a layer which exists between a blackening layer and another layer (base material etc.), and has a function which improves adhesion between these layers.
なお密着層は、チタン、ニッケル、及びクロムからなる群より選ばれる少なくとも1つの元素を含む層であるため、例えば、チタン、ニッケル、又はクロムの純粋な金属を含む層でもいいし、チタン、ニッケル、又はクロムを有する化合物を含む層であってもいい。そのため密着層は、黒化層と同様に窒化ニッケルや酸化ニッケルなどを含む層となる場合がある。 The adhesion layer is a layer containing at least one element selected from the group consisting of titanium, nickel, and chromium. For example, the adhesion layer may be a layer containing pure metal such as titanium, nickel, or chromium. Or a layer containing a compound containing chromium. Therefore, the adhesion layer may be a layer containing nickel nitride, nickel oxide, or the like, similar to the blackening layer.
なお密着層は、層の全体100原子%において、チタン、ニッケル、及びクロム元素の合計含有量(原子数基準)が、50原子%以上100原子%の層であることが好ましい。この原子数の確認は、前述の条件によるエッチングとオージェ電子分光法によって可能である。 Note that the adhesion layer is preferably a layer in which the total content of titanium, nickel, and chromium elements (on the basis of the number of atoms) is 50 atomic% or more and 100 atomic% in the entire layer of 100 atomic%. This number of atoms can be confirmed by etching and Auger electron spectroscopy under the aforementioned conditions.
なお本発明では、層の組成の観点から、黒化層にも密着層にも該当する層が存在する場合、それは以下の基準に従って判断する。
1)層の組成の観点から、黒化層にも密着層にも該当する層が存在する場合、原則その層は黒化層としてカウントする。
2)層の組成の観点から、黒化層にも密着層にも該当する層が接して存在する場合、積層体の最表面に存在する層は黒化層としてカウントし、積層体の内層に存在する層は密着層としてカウントする。これは、密着層は、黒化層と別の層(基材など)との間に存在して、これらの層間の密着性を向上する機能を有する層だからである。
3)層の組成の観点から、黒化層にも密着層にも該当する層が接して存在し、さらにこれらの層が両方とも積層体の最表層には存在しない場合(これらの層が両方とも積層体の内層に存在する場合)、厚みの厚い層を黒化層とし、厚みの薄い層を密着層としてカウントする。
本発明の積層体が密着層を含むことは、密着層を介して黒化層と他の層との密着性を、密着層が存在しない場合と比較して向上できるために好ましい。図1の第一実施の形態の積層体では、密着層A1が存在すると、金属層A1と基材とが直接密着した場合と比較して、金属層A1と基材との密着性を向上させることができるために好ましい。また、図1の態様の積層体において密着層A2が存在すると、基材と黒化層A2とが直接密着した場合と比較して、基材と黒化層A2との密着層を向上させることができるために好ましい。
In the present invention, from the viewpoint of the composition of the layer, when a layer corresponding to both the blackening layer and the adhesion layer exists, it is determined according to the following criteria.
1) From the viewpoint of the composition of the layer, when a layer corresponding to both the blackened layer and the adhesion layer exists, the layer is counted as a blackened layer in principle.
2) From the viewpoint of the composition of the layer, when a layer corresponding to both the blackened layer and the adhesion layer is present in contact, the layer present on the outermost surface of the laminate is counted as a blackened layer, and the inner layer of the laminate is The existing layer is counted as an adhesion layer. This is because the adhesion layer exists between the blackened layer and another layer (such as a base material) and has a function of improving the adhesion between these layers.
3) From the viewpoint of the composition of the layer, a layer corresponding to both the blackening layer and the adhesion layer is present in contact with each other, and furthermore, both of these layers are not present in the outermost layer of the laminate (both these layers are present) In the case where both are present in the inner layer of the laminate, the thick layer is counted as a blackening layer, and the thin layer is counted as an adhesion layer.
It is preferable that the laminate of the present invention includes an adhesion layer because the adhesion between the blackened layer and other layers can be improved through the adhesion layer as compared with the case where no adhesion layer exists. In the laminate of the first embodiment in FIG. 1, when the adhesion layer A1 is present, the adhesion between the metal layer A1 and the substrate is improved as compared with the case where the metal layer A1 and the substrate are directly adhered. This is preferable because it can be performed. Moreover, when the adhesion layer A2 is present in the laminate of the embodiment of FIG. 1, the adhesion layer between the base material and the blackening layer A2 is improved as compared with the case where the base material and the blackening layer A2 are in direct contact. It is preferable because
密着層の形成方法は特に限定されず、選択される密着層の素材に応じて適宜形成方法を選ぶことができる。なお、スパッタリング法、蒸着法、又はイオンプレーティング法は、チタン、ニッケル、クロムのいずれを含む層の形成にも適用することができるために好ましい形成方法である。 The formation method of an adhesion layer is not specifically limited, According to the raw material of the adhesion layer selected, a formation method can be selected suitably. Note that a sputtering method, an evaporation method, or an ion plating method is a preferable formation method because it can be applied to formation of a layer containing any of titanium, nickel, and chromium.
密着層の厚さは、0.5nm以上500nm以下が好適であり、1nm以上100nm以下がより好適であり、1nm以上50nm以下が更により好適である。密着層の厚さが0.5nmより小さいと、十分な密着効果が得られない事がある。また、密着層の厚さが500nmを超えても、得られる密着性が更に増すわけではないので、コストの観点から、密着層は500nm以下が好ましい。 The thickness of the adhesion layer is preferably 0.5 nm to 500 nm, more preferably 1 nm to 100 nm, and even more preferably 1 nm to 50 nm. If the thickness of the adhesion layer is smaller than 0.5 nm, a sufficient adhesion effect may not be obtained. Further, even if the thickness of the adhesion layer exceeds 500 nm, the obtained adhesion does not increase further, so that the adhesion layer is preferably 500 nm or less from the viewpoint of cost.
第一実施の形態の積層体A1は、黒化層A1(2a)、金属層A1(4a)、基材(3)、黒化層A2(2b)、金属層A2(4b)をこの順で有する。この順に積層することで、視認側(図1の上側)から見たときに、黒化層A1(2a)と黒化層A2(2b)とが、金属層A1(4a)と金属層A2(4b)のいずれの表面をもそれぞれ覆うこととなり、タッチセンサー下に配置されるディスプレイの像のコントラストが低下することを防止する効果を有する。また、2つの金属層が絶縁性の基材(3)を挟んで配置されることで、表裏の黒化層、金属層、密着層のパターニングを一括で行うことができ、従来の2枚の電極を貼り合せて成るタッチセンサーで問題となった貼り合せズレによるモアレ発生を防ぐことができる。 The laminated body A1 of the first embodiment includes the blackened layer A1 (2a), the metal layer A1 (4a), the base material (3), the blackened layer A2 (2b), and the metal layer A2 (4b) in this order. Have. By laminating in this order, when viewed from the viewing side (upper side in FIG. 1), the blackened layer A1 (2a) and the blackened layer A2 (2b) are formed into the metal layer A1 (4a) and the metal layer A2 ( Each of the surfaces of 4b) is covered, and has an effect of preventing the contrast of the image of the display disposed under the touch sensor from being lowered. Moreover, by arranging the two metal layers with the insulating base material (3) sandwiched between them, the patterning of the black and white layers, the metal layer, and the adhesion layer on the front and back sides can be performed in a lump. It is possible to prevent the occurrence of moiré due to bonding misalignment, which is a problem with touch sensors formed by bonding electrodes.

第二実施の形態の積層体の各層は、特記しない限り、第一実施の形態の項で説明したとおりの役割や態様である。以下、第二実施の形態について、第一実施の形態と異なる部分のみ詳細を説明する。
In the laminate of the present invention in which the blackening layer B1, the metal layer B1, the blackening layer B2, the adhesion layer B1, and the base material are solid films, the blackening layer, the metal layer, and the adhesion layer are partially removed. By using a patterned blackening layer, a metal layer, and an adhesion layer, it can be suitably used as an electrode of a touch sensor. And by setting it as the laminated body of 2nd embodiment of this invention which has a pattern-like blackening layer, a metal layer, and an adhesion layer, either the front or back (namely, blackening layer B1 side and base material side) It can also be suitably used as a heater or an electromagnetic shielding material that can be visually recognized.
Unless otherwise specified, each layer of the laminate of the second embodiment has a role and mode as described in the section of the first embodiment. Hereinafter, the second embodiment will be described in detail only for parts different from the first embodiment.
黒化層B1及び黒化層B2は、金属層B1をそれぞれの面から覆うように存在している。このようにすることで、金属層B1が金属光沢を持つ場合や有彩色である場合に、金属層B1の表面反射によりディスプレイに写される像のコントラストが低下するのを防ぐ効果がある。また積層体越しに物体を見る場合、積層体の表側及び裏側どちらからみても、金属層B1の表面反射により物体のコントラストが低下することや、物体の色目が変わってしまうことを防ぐ効果がある。 The blackening layer B1 and the blackening layer B2 exist so as to cover the metal layer B1 from each surface. By doing in this way, when the metal layer B1 has a metallic luster or a chromatic color, there is an effect of preventing the contrast of an image projected on the display from being lowered due to the surface reflection of the metal layer B1. Further, when the object is viewed through the laminated body, there is an effect of preventing the contrast of the object from being lowered and the color of the object from being changed due to the surface reflection of the metal layer B1 when viewed from the front side or the back side of the laminated body. .
黒化層B1と黒化層B2の形成方法は特に限定されず、例えば、スパッタリング法やメッキ法によって形成することができる。黒化層B1と黒化層B2を異なる方法で形成しても構わない。 The formation method of the blackening layer B1 and the blackening layer B2 is not specifically limited, For example, it can form by sputtering method or a plating method. The blackening layer B1 and the blackening layer B2 may be formed by different methods.
黒化層B1と黒化層B2の厚みは特に限定されないが、5nm以上200,000nm以下が好ましく、10nm以上11,000nm以下がより好ましい。黒化層B1や黒化層B2の厚みが5nm未満の場合には、黒化層B1や黒化層B2を透過する光が多くなり前述の効果を十分に発揮できないことがある。黒化層B1や黒化層B2の厚みが200,000nmを越えると黒化層B1や黒化層B2を部分的に除去した際に黒化層B1や黒化層B2の側面が透過光を遮ってタッチパネルのディスプレイや、ヒーターおよびシールド材料の透過像の視野角が制限されることがある。 The thicknesses of the blackening layer B1 and the blackening layer B2 are not particularly limited, but are preferably 5 nm or more and 200,000 nm or less, and more preferably 10 nm or more and 11,000 nm or less. When the thickness of the blackening layer B1 or the blackening layer B2 is less than 5 nm, the light transmitted through the blackening layer B1 or the blackening layer B2 increases, and the above-described effects may not be sufficiently exhibited. When the thickness of the blackened layer B1 or blackened layer B2 exceeds 200,000 nm, the side surfaces of the blackened layer B1 or blackened layer B2 transmit transmitted light when the blackened layer B1 or blackened layer B2 is partially removed. Occlusion may limit the viewing angle of the touch panel display and the transmission image of the heater and shield material.
第二実施の形態の積層体は、黒化層B2と基材の間に密着層B1を有することが好ましい。密着層B1を設ける理由は、エッチングや保護フィルム剥離などの後工程で、黒化層B2と基材が剥がれるのを防止することである。
[第三実施の形態]

The laminate of the second embodiment preferably has an adhesion layer B1 between the blackening layer B2 and the substrate. The reason for providing the adhesion layer B1 is to prevent the blackening layer B2 and the substrate from being peeled off in a subsequent step such as etching or protective film peeling.

In particular, it is suitable as a touch sensor electrode of a see-through display that is visible from both the front and back (that is, the blackened layer C1 side and the blackened layer C4).
第三実施の形態の積層体の各層は、特記しない限り、第二実施の形態の項で説明したとおりの役割や態様である。
[本発明の積層体]
本発明の積層体は、全光線透過率が20%以上であることが好ましく、50%以上であることがより好ましい。全光線透過率が高いほどタッチセンサー下に配置されるディスプレイの像のコントラストが向上するからである。積層体の全光線透過率は高ければ高いほど好ましいが、現実的に得られる上限は99%以下である。なお、積層体の全光線透過率は、少なくとも一方の面から測定して、20%以上であれば十分である。
Unless otherwise specified, each layer of the laminate of the third embodiment has the role and mode as described in the section of the second embodiment.
[Laminated body of the present invention]
The laminate of the present invention preferably has a total light transmittance of 20% or more, and more preferably 50% or more. This is because as the total light transmittance is higher, the contrast of the image of the display arranged under the touch sensor is improved. The higher the total light transmittance of the laminate, the better. However, the practical upper limit is 99% or less. The total light transmittance of the laminate is sufficient if it is 20% or more as measured from at least one surface.
なお、積層体の全光線透過率を20%以上とするためには、全光線透過率の高い基材を用いることが好ましいが、その他には、積層体を構成する黒化層、金属層、密着層を、パターン状とすることが好ましい。厚みにも依存するが、黒化層、金属層、密着層などはそれを構成する原料が理由で全光線透過率が低いが、黒化層、金属層、密着層を大幅に除去(図2)して、パターン状とすることで、金属層などが存在しない部分ができることになるので、全光線透過率の優れた積層体とすることができる。パターン形状の例としては、ストライプ状やメッシュ状、ダイヤパターンを挙げることができる。パターン形状は全面に一様である必要はなく、周辺に引き出し電極を配したり、ダイヤパターンの内部をメッシュ状に変換したりしても構わない。
本発明の積層体の表面抵抗率は0.001Ω/sq.以上3,000Ω/sq.以下が好ましく、0.01Ω/sq.以上1,000Ω/sq.以下がより好ましい。3,000Ω/sq.を超える表面抵抗率の積層体を用いてタッチセンサーとしたときは、タッチセンサーの応答速度が遅くなってしまうことがあるため、積層体の表面抵抗率を3,000Ω/sq.よりも大きくすることは好ましくない。また、0.001Ω/sq.未満の積層体としても、電極として用いた場合の性能に問題はないが、低抵抗を得るために金属層や黒化層、密着層の厚みを大きくする必要が生じるので、コストの点で好ましくない。なお、積層体の表面抵抗率は、少なくとも一方の面において、0.001Ω/sq.以上3,000Ω/sq.以下であれば十分である。
In order to make the total light transmittance of the laminate 20% or more, it is preferable to use a substrate having a high total light transmittance, but in addition, a blackened layer, a metal layer, It is preferable that the adhesion layer has a pattern. Although depending on the thickness, the blackened layer, the metal layer, and the adhesive layer have low total light transmittance because of the raw materials constituting the blackened layer, the metal layer, and the adhesive layer. ) And forming a pattern, a portion having no metal layer or the like is formed, so that a laminate having excellent total light transmittance can be obtained. Examples of pattern shapes include stripes, meshes, and diamond patterns. The pattern shape does not need to be uniform over the entire surface, and lead electrodes may be arranged around the periphery, or the inside of the diamond pattern may be converted into a mesh shape.
The surface resistivity of the laminate of the present invention is 0.001 Ω / sq. 3,000 Ω / sq. Or less, preferably 0.01 Ω / sq. 1,000 Ω / sq. The following is more preferable. 3,000Ω / sq. When a laminated body having a surface resistivity exceeding 30 mm is used as a touch sensor, the response speed of the touch sensor may be slowed down, so that the laminated body has a surface resistivity of 3,000 Ω / sq. It is not preferable to make it larger. In addition, 0.001Ω / sq. Even if it is less than the laminated body, there is no problem in performance when used as an electrode, but it is necessary in terms of cost because it is necessary to increase the thickness of the metal layer, the blackening layer, and the adhesion layer in order to obtain low resistance. Absent. Note that the surface resistivity of the laminated body is 0.001 Ω / sq. 3,000 Ω / sq. The following is sufficient.
なお、積層体の表面抵抗率を0.001Ω/sq.以上3,000Ω/sq.以下とするためには、例えば、金属層の厚みを10nm以上200,000nm以下とする方法を挙げることができる。 The surface resistivity of the laminate is 0.001 Ω / sq. 3,000 Ω / sq. For example, a method of setting the thickness of the metal layer to 10 nm or more and 200,000 nm or less can be used.
上記で説明した積層体は、第一実施の形態および第三実施の形態において、配線部の金属光沢反射光によりタッチセンサー下に配置されるディスプレイの視認性を低下することなく、またメッシュ状としても2枚のフィルムの貼り合せズレを生じない透明導電性フィルムに適用することが可能である。 In the first embodiment and the third embodiment, the laminated body described above is formed as a mesh without reducing the visibility of the display arranged under the touch sensor by the metallic gloss reflected light of the wiring portion. Can also be applied to a transparent conductive film that does not cause misalignment of the two films.
また、上記で説明した積層体は、第二実施の形態および第三実施の形態において、表裏どちら側から見ても配線部の金属光沢反射光により、積層体を透過した透過光に対する視認性を低下することのない透明導電性フィルムに適用することが可能である。該透明導電性フィルムはヒーターや電磁波シールド、シースルー型タッチパネルに好適に適用できる。
In addition, in the second embodiment and the third embodiment, the laminated body described above has visibility to the transmitted light transmitted through the laminated body by the metallic gloss reflected light of the wiring portion when viewed from either the front or back side. It is possible to apply to the transparent conductive film which does not fall. The transparent conductive film can be suitably applied to heaters, electromagnetic wave shields, and see-through touch panels.
