Description

Metal sticker and manufacturing method thereof {Metal sticker and manufacturing method of the same}

The present invention relates to a metal sticker and a method of manufacturing the same. More specifically, the present invention is a metal sticker for decorating the appearance of a portable communication terminal such as a mobile phone or other desired items with a stylish metal style, and implements various colors or glossiness of matte and gloss for a part without additional complicated process. The present invention relates to a metal sticker and a method of manufacturing the same, which can further improve aesthetics.

Generally, a sticker is a generic name of a print made to be attached to a desired position by using glue or adhesive, and generally refers to a sheet-shaped product that is commonly used for advertisement and promotional purposes.

These stickers can be divided into paper, synthetic resin, and metal depending on their materials. In particular, the metal sticker, which represents a sheet of metal, has a feeling of luxury due to the high gloss that is hard to be found in other types. At the same time, it is not easy to imitate, so it has the function of anti-counterfeiting, and it has little restrictions on shape, size, shape, etc.

As a result, Yosai metal stickers are attracting much attention in the fields of advertisements, promotions, nameplates, accessories, promotional items, and crafts.

On the other hand, the manufacture of general metal stickers includes a number of patterning steps by electro-forming and / or photolithography using a mold, and these are sheet metal using a press. Compared to processing, there is an advantage that a finer and smoother cutting surface can be obtained.

However, the method shows a disadvantage in that the consumption of time and cost is high and the yield is low. The present applicants have the following patent applications: 10-2001-0060651, 10-2004-009737, 10-2005-0037871, 10-2005-0044674 and the like introduced a method of manufacturing low-cost fast and sophisticated metal stickers.

The patent technology is briefly described as follows.

First, a photoresist layer of photocurable polymer is applied to one surface of a base substrate made of a conductive material such as stainless steel to realize a photoresist layer having a predetermined thickness. The photoresist layer is suitably patterned through a photolithography process such as exposure with a mask and development using a developer to obtain a photoresist pattern having a desired shape.

This obtains a mold by the base substrate and the photoresist pattern.

Subsequently, metal plating is performed on one surface of the base substrate to fill a plating layer between the photoresist patterns to obtain a metal sticker of a thin plate pattern by the plating layer, and then the base is formed of an adhesive protective film. After selectively separating only the metal sticker from the substrate and the photoresist pattern, an adhesive layer is formed on the bottom surface of the metal sticker, and the release paper is attached to the substrate.

Therefore, the user can remove the release paper and then attach the metal sticker to the outer surface of the desired article, and then use the method of removing the protective film. The metal sticker shows a luxurious metallic color of gold or silver depending on the type of plating metal. The exterior of the item is decorated with a refined metal style.

However, general metal stickers show a limitation in gloss control of various parts of the product and gloss or various color implementations.

That is, since the general metal sticker is made of a simple thin plate structure of the metal by plating or deposition, it emits gold or silver monochromatic light depending on the type of the plating metal. Therefore, in order to control the gloss and color of matte and gloss on part of the product, additional additional steps such as matte or gloss plating or color coloring should be additionally performed. This has to be done, which in turn increases the time and cost of the overall process and causes a problem in yield.

The present invention has been made to solve the above problems, and suggests a specific method capable of selective gloss or various color implementation of the selective matte and gloss for some without the additional complicated additional process of the manufacturing process of the metal sticker. Purpose.

In addition, the step (e) further comprises the step of plating a metal on one surface of the base substrate to form a matte or glossy plated layer along the thin plate pattern exposed from the mask pattern, wherein the pattern layer is the matte or And a step of removing the mask pattern (e1) after the step (e) and before the step (f), after the step (e). 1 t (t1), and after the step (e1) and before the (f) step, (e2) the plated metal and the outer surface of the pattern layer are plated with metal to form a color plated layer having a second thickness (t2, where t1> t2). It characterized in that it further comprises the step of forming.

In addition, the step (e) further comprises the step of color printing or painting the paint layer on one surface of the base substrate, wherein the pattern layer is characterized in that the paint layer.

As a result, the present invention can provide a metal sticker of a more refined and diverse feeling while minimizing unnecessary cost and time consumption, and the user who uses it has an advantage of expressing his personality more freely.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a preferred embodiment of the metal sticker according to the present invention, Figure 2 is a cross-sectional view taken along the line II-II of FIG. At this time, although the figure is shown in the form suitable for decorating the outer surface of the mobile phone is just an example of the present invention, the specific shape can be variously modified according to the purpose it will be easily understood by those skilled in the art through the following description Can be.

As can be seen, the metal sticker according to the present invention is in the form of a sheet to be attached to an object to be attached, for example, a mobile phone, and if necessary, a predetermined opening (A) through which a necessary part such as a display window or a button of the mobile phone can be penetrated. The upper and lower surfaces of the adhesive film 30 and the release paper 50 are respectively bonded to each other. In addition, the metal sticker according to the present invention interposed between the adhesive film 30 and the release paper 50 is selectively present on the lower plate pattern 10 and a part of an outer surface thereof, which are made of a matt or glossy metal thin plate structure. It includes a pattern layer 20 to implement a gloss control effect or a variety of colors by the gloss, the adhesive layer 42 is formed on the bottom of the thin plate pattern 10 to provide an attachment surface for attachment to the object to be attached.

Therefore, the user can peel off the release paper 50 and then attach the adhesive layer 42 of the thin plate pattern 10 to the desired article, for example, the outer surface of the mobile phone, and then peel off the adhesive film 30 to use it conveniently. The thin plate pattern 10 attached to the article provides a matte or shiny polished metal-like background, while the pattern layer 20 selectively present on a part of the outer surface shows a pattern of matte or glossy or various colors.

Looking at each of them in detail as follows.

First, the thin plate pattern 10 is made of a matte or glossy metal plating layer, the material is any kind of metal that can be laminated over a certain thickness through the usual dry or wet plating, such as nickel, chromium, copper, silver, gold This can be used.

At this time, if necessary, the thin plate pattern 10 may have a laminated structure of at least two plating layers, and a predetermined adhesive layer 42 made of an adhesive material is present on the bottom surface of the thin plate pattern 10.

Next, the pattern layer 20 is selectively present on the outer surface of the thin plate pattern 10, the material is made of a matte or glossy metal plating layer of the same or different color as the thin plate pattern 10 or a paint layer of various colors. .

As a result, when the pattern layer 20 is an electron metal plating layer, the thin plate pattern 10 and the pattern layer 20 are matte-matte, matte-glossy, glossy-matte, glossy-glossy with the same or different metallic colors. If one of the gloss combinations and the pattern layer 20 is the latter coating layer, various colors are implemented based on a matt or glossy metal color of the thin plate pattern 10.

For reference, the pattern layer 20 may have various shapes such as letters, numbers, or predetermined patterns repeatedly arranged according to a predetermined rule as shown in the drawing.

Next, the adhesive film 30 covers the upper surfaces of the thin plate pattern 10 and the pattern layer 20 to prevent damage such as scratches that may appear during the distribution process and to easily observe the metal sticker from the outside. Adhesive film 30 for this is made of a transparent synthetic resin material PET (Poly Ethylene Terephthalate), PC (Poly Carbonate), acrylic (acryloyl), urethane (urethane) system, the thin plate pattern 10 and the pattern layer 20 A predetermined adhesive is applied to the bottom of the adhesive film 30 to be in close contact.

At this time, the adhesive force of the adhesive film 30 is preferably smaller than that of the thin plate pattern (10).

Finally, the release paper 50 is made of a paper coated with a silicon resin on the upper surface facing the adhesive film 30, such as commonly referred to as backing paper, between the thin plate pattern 10 and the pattern layer 20 It is attached to the adhesive film 30 and serves to protect the thin plate pattern 10 and the pattern layer 20 from the external impact that can be applied during the distribution process.

On the other hand, the metal sticker according to the present invention described above is matte as the pattern layer 20 consisting of a glossy or matte metal plating layer or a coating layer is selectively present on the outer surface of the thin plate pattern 10 consisting of a glossy or matte metal plating layer. And the gloss control effect of the gloss or various colors, as well as the adhesion of the adhesive film 30 and the release paper 50, including the thin plate pattern 10 and the pattern layer 20, are a series of continuous processes. Bar, characterized in that below, looks at in detail the manufacturing method of the metal sticker according to the present invention.

3 is a flowchart illustrating a method of manufacturing a metal sticker according to the present invention, and FIGS. 4 to 14 are cross-sectional views according to a process sequence, respectively.

First, the base substrate 2 is prepared as shown in Fig. 4 (st1).

At this time, since the base substrate 2 is used as another electrode in the plating to be described later, a stainless steel material having conductivity and the like is appropriate.

Next, as shown in FIG. 5, the photoresist layer 4 is formed on one surface of the base substrate 2 to have a predetermined thickness. (St2)

At this time, the photoresist layer 4 may be obtained by a process of applying and curing the photoresist or attaching and curing the standardized photoresist film.

Then, if necessary, a thin uneven pattern scratch is generated on one surface of the base substrate 2 before the photoresist layer 4 is formed. Can be easily removed. The technique is described in detail in the Invention Application No. 2001-0060651 by the present applicant, in contrast to general polishing for obtaining a smooth surface, by roughening the surface of the base substrate 2 by a separate strike treatment and / or peeling coating In order to replace the, the surface of the base substrate 2 is sprayed with abrasives such as emery or molten alumina and then rubbed with a metal brush to generate scratches.

Next, the mask is placed face-up on the photoresist layer 4 and exposed to light, followed by development with an appropriate developer to remove a portion of the photoresist layer 4, thereby thin plate pattern 10 to be described later as shown in FIG. By showing the opposite intaglio shape, the photoresist pattern 6 exposing the base substrate 2 is formed in the same form as the thin plate pattern 10 (st3).

In this case, the mask may be formed of a printed film or the like for blocking light and a light transmitting part that transmits light, and under the premise that the photoresist is a negative type, for example, the mask blocking part of the mask may be exposed and developed. The portion corresponding to is removed to obtain a photoresist pattern 6 of a desired form.

Next, as shown in FIG. 7, metal plating is performed on one surface of the base substrate 2 on which the photoresist pattern 6 is formed to form a thin plate pattern 10 by a glossy or matt metal plating layer. (St4)

At this time, the plating method is immersed in the electrolytic cell containing the plating solution and the base material (2) and the metal material to be plated, such as nickel plate, and then applied a negative voltage to the base substrate (2) and the metal material, respectively. A suitable method of applying wet electroplating or dry plating may be used, whereby a plating layer of metal is filled along one surface of the conductive base substrate 2 exposed through the photoresist pattern 2 to obtain a thin plate pattern 10. . In this case, if necessary, the thin plate pattern 10 may exhibit a lamination structure of at least two plating layers, such as a plating layer of gold, silver, or the like, deposited on a relatively inexpensive base film such as nickel.

Next, as shown in FIG. 8, a mask pattern 16 of a non-metal material is formed on the outer surfaces of the thin plate pattern 10 and the photoresist pattern 6 to expose a portion of the thin plate pattern 10. (St5)

In this case, the mask pattern 16 may be one of a photoresist, a film, and a silk screen. In the case of the photoresist, the thin film pattern 10 and the photoresist pattern 6 are separately separated in the same manner as in the above-described st2 to st3 process. After the photoresist layer is formed, it can be realized through the process of exposure and development using another mask, and in the case of film and silk screen, the sheet is cut in advance into the thin plate pattern 10 and the photoresist pattern 6. A manner of attachment may be used.

Next, as shown in FIG. 9, the outer surface of the thin plate pattern 10 on which the mask pattern 16 is formed is subjected to matt metal or gloss metal plating, or color printing or painting of an appropriate paint to implement the pattern layer 20. )

At this time, a suitable method of wet or dry plating may be used as the plating method, and thus, the pattern layer 20 may be completed by filling a metal plating layer of matt or gloss between the mask patterns 16. In this case, the mask pattern 16 is preferably made of photoresist.

In addition, in the case of color printing or painting, the pattern layer 20 can be completed by color printing or spray-spraying a coating material of a desired color. In this case, the mask pattern 16 may be any of photoresist, film, and silk screen.

Next, the mask pattern 16 is removed as shown in Fig. 10. (st7)

At this time, this step is not essential, so it may be omitted as necessary, which will be described in detail in the corresponding part, for reference, when the mask pattern 16 is made of a photoresist, a suitable peeling liquid may be used, the contact time Or the composition is appropriately adjusted so that only the mask pattern 16 is removed. In this case, part of the photoresist pattern 6 may be removed together unless the base substrate 2 other than the thin plate pattern 10 is exposed.

On the other hand, if it is a film or silkscreen, remove it by peeling off each.

Next, as shown in FIG. 11, the adhesive film 30 is adhered to the outer surface of the pattern layer 20 and then peeled off, except for the base substrate 10 and the photoresist pattern 6, that is, the thin plate pattern 10 and the pattern. The layer 16 is separated from the base substrate 2 and the photoresist pattern 6. (st8)

At this time, when the photoresist pattern 6 is attached to and detached from the adhesive film 30, the shape of the metal sticker may be deteriorated. However, since the photoresist pattern 6 exhibits a significant step with the pattern layer 20, There is no difficulty in the selective separation of the thin plate pattern 10 and the pattern layer 20, even if the adhesive film 30 is partially adhered to the photoresist pattern 6, if the adhesive force of the adhesive film 30 is properly adjusted, the base Since the adhesive force between the adhesive film 30 and the pattern layer 20 can be made larger than the adhesive force between the substrate 2 and the photoresist pattern 6, it is possible to selectively separate only the thin plate pattern 10 and the pattern layer 20. It is possible.

In addition, since the base substrate 10 and the photoresist pattern 6 in which the thin plate pattern 10 and the pattern layer 16 and the like are separated remain circular, they are used again in the manufacture of subsequent metal stickers.

Next, as shown in FIG. 12, the adhesive layer 42 is formed on the bottom surface of the thin plate pattern 10. (St9)

Lastly, as shown in FIG. 13, the release paper 50 is attached to the adhesive film 40 with the thin plate pattern 10 and the pattern layer 20 interposed therebetween, thereby providing the present invention shown in FIGS. 1 and 2. Accordingly a metal sticker is obtained.

Meanwhile, the metal sticker according to the present invention can be modified to a certain degree in a specific form or manufacturing process, and some examples thereof are shown in FIGS. 14 and 15 in the form of a sectional view similar to FIG. 2. In this case, the same reference numerals are given to the same parts that play the same role as described above in order to avoid unnecessary overlapping description, and these drawings are referred to together with the drawings appropriately referred to in FIGS. 3 to 13.

First, in the metal sticker illustrated in FIG. 14, a separate color plating layer 62 exists along the outer surfaces of the thin plate pattern 10 and the pattern layer 20, and the adhesive film 30 is formed on the outer surface of the color plating layer 62. Attached.

This modified example is the thin plate pattern 10 and the pattern layer (step) before the attachment and detachment of the st8 and the adhesive film 30 of FIG. 11 after removing the mask pattern 16 of FIGS. It can be obtained by performing a separate metal plating along the outer surface of the 20, this color plating layer 62 is a thin plate pattern 10 and the pattern without the matt effect of the thin plate pattern 10 or pattern layer 20 Allow layer 20 to show the same metallic color.

To this end, when the thickness of the pattern layer 20 is arbitrarily referred to as the first thickness t1, the thickness of the color plating layer needs to be limited to a smaller second thickness t2 (where t1> t2), and the color plating layer 62 By using a material of a high-quality color, such as gold or silver, the thin plate pattern 10 and the pattern layer 20 may be made of a relatively inexpensive metal material, thereby reducing the cost.

Next, in the metal sticker shown in FIG. 15, the mask pattern 16 remains on the outer surface of the thin plate pattern 10, and the adhesive film 30 is attached to the outer surface of the pattern layer 20 and the mask pattern 16.

This modification can be obtained by omitting the steps of removing the mask pattern 16 of FIG. 10 and st7 after implementing the st6 of FIG. 3 and the pattern layer 20 of FIG. 9, wherein the mask pattern 16 is made of metal. It emphasizes the aesthetics of stickers.

To this end, the mask pattern 16 is preferably a film colored in the desired color, and the pattern layer 20 is plated or printed with color printing to prevent unnecessary contamination of the mask pattern 16 during the formation process. It is appropriate to be implemented.

In addition, in the above description, the contents obvious to those skilled in the art may be unnecessarily obscured, and thus omitted. For example, the base substrate 2 in the step before forming the photoresist layer 4 on the base substrate 2 may be omitted. ) May be added, as well as performing a predetermined heat treatment to increase the strength of the photoresist pattern 6 after development, and scratches of fine irregularities on one surface of the base substrate 2. It is also possible to form a strike treatment and / or a peeling film instead of generating.

Therefore, the present invention described above is only a preferable example, and it can be easily appreciated by those skilled in the art that there may be various modifications to satisfy this. However, if these modifications fall within the technical spirit of the present invention, it should be regarded as falling within the scope of the present invention, and the scope of the present invention is clearly shown in the following claims.
