- the forward wavelength dispersive refractive index represents a refractive index in which the absolute value of the refractive index decreases as the measurement wavelength increases. Since the refractive index n1 of the main chain mesogen 1a has a small forward wavelength dispersion, the refractive index measured at a long wavelength is not significantly smaller than the refractive index measured at a short wavelength.
- the refractive index n2 of the side chain mesogen 1b has a large forward wavelength dispersion, the refractive index measured at the long wavelength is significantly smaller than the refractive index measured at the short wavelength. Therefore, when the measurement wavelength is short, the difference ⁇ n between the refractive index n1 and the refractive index n2 is small, and when the measurement wavelength is long, the difference ⁇ n between the refractive index n1 and the refractive index n2 is large. In this way, the reverse wavelength dispersive birefringence can be expressed from the main chain mesogen 1a and the side chain mesogen 1b.

本発明の位相差層の製造方法によれば、逆波長分散性の複屈折を発現しうる重合性液晶化合物を用いて、面状態及び配向性の両方に優れる位相差層を製造できる。

逆波長重合性液晶化合物は、液晶性を有するので、当該逆波長重合性液晶化合物を配向させたときに、液晶相を呈しうる。また、逆波長重合性液晶化合物は、重合性を有するので、前記のように液晶相を呈した状態で重合し、液晶相における分子の配向を維持したままま重合体となりうる。本発明の液晶性組成物が前記のような逆波長重合性液晶化合物を含むので、本発明の液晶性組成物を用いて位相差層を製造することができる。
逆波長分散性の複屈折とは、波長450nmにおける複屈折Δn(450)及び波長650nmにおける複屈折Δn(650)が、下記式(1)を満たす複屈折をいう。このような逆波長分散性の複屈折を発現しうる前記の逆波長重合性液晶化合物は、通常、測定波長が長いほど、大きい複屈折を発現しうる。したがって、通常、逆波長重合性液晶化合物を前述のように重合させた重合体の複屈折は、下記式(2)を満たす。下記式(2)において、Δn(550)は、測定波長550nmにおける複屈折を表す。

本発明の液晶性組成物は、分子中にフッ素原子を含む界面活性剤を含む。この界面活性剤の分子中のフッ素原子の割合は、通常30重量%以下、好ましくは25重量%以下、より好ましくは20重量%以下である。このように所定の割合でフッ素原子を含む界面活性剤を逆波長重合性液晶化合物と組み合わせて用いることにより、本発明の液晶性組成物を用いて製造される位相差層の面状態及び配向性の両方を良好にできる。さらに、通常は、位相差層の位相差ムラ及び厚みムラを抑制することが可能である。
試料としての界面活性剤を秤量し、分析装置の燃焼管内で燃焼させる。燃焼により発生したガスを、適切な溶液に吸収させて、吸収液を得る。その後、吸収液の一部をイオンクロマトグラフィーにより分析することによって、界面活性剤の分子中のフッ素原子の割合を測定しうる。
溶媒としては、逆波長重合性液晶化合物を溶解できるものを用いうる。このような溶媒としては、通常、有機溶媒を用いる。有機溶媒の例としては、シクロペンタノン、シクロヘキサノン、メチルエチルケトン、アセトン、メチルイソブチルケトン等のケトン溶媒;酢酸ブチル、酢酸アミル等の酢酸エステル溶媒;クロロホルム、ジクロロメタン、ジクロロエタン等のハロゲン化炭化水素溶媒;1,4-ジオキサン、シクロペンチルメチルエーテル、テトラヒドロフラン、テトラヒドロピラン、1,3-ジオキソラン、1,2-ジメトキシエタン等のエーテル溶媒;及びトルエン、キシレン、メシチレン等の芳香族炭化水素;が挙げられる。
本発明の液晶性組成物は、前述した逆波長重合性液晶化合物、界面活性剤及び溶媒に組み合わせて、更に任意の成分を含みうる。
本発明の液晶性組成物を用いることにより、位相差層を製造できる。このような位相差層の製造方法は、
(i)支持面に、本発明の液晶性組成物を塗布して、液晶性組成物の層を形成する工程と、
(ii)液晶性組成物の層に含まれる逆波長重合性液晶化合物を配向させる工程と、
(iii)逆波長重合性液晶化合物を重合させて、位相差層を得る工程と
を含む。
支持面としては、液晶性組成物の層を支持できる任意の面を用いうる。この支持面としては、位相差層の面状態を良好にする観点から、通常、凹部及び凸部の無い平坦面を用いる。位相差層の生産性を高める観点から、前記の支持面としては、長尺の基材の表面を用いることが好ましい。ここで「長尺」とは、幅に対して、少なくとも5倍以上の長さを有する形状をいい、好ましくは10倍若しくはそれ以上の長さを有し、具体的にはロール状に巻き取られて保管又は運搬される程度の長さを有するフィルムの形状をいう。
前記の延伸は、テンター延伸機などの延伸機を用いて行いうる。
液晶性組成物の層を形成した後で、当該層に含まれる逆波長重合性液晶化合物を配向させる工程を行う。通常は、液晶性組成物の層に、加温等の配向処理を施すことにより、逆波長重合性液晶化合物を配向させられる。配向処理の条件は、使用する液晶性組成物の性質に応じて適切に設定しうる。配向処理の条件の具体例を挙げると、50℃~160℃の温度条件において、30秒間~5分間処理する条件としうる。
逆波長重合性液晶化合物を配向させた後で、逆波長重合性液晶化合物を重合させて、位相差層を得る工程を行う。逆波長重合性液晶化合物の重合方法としては、液晶性組成物に含まれる成分の性質に適合した方法を選択しうる。重合方法としては、例えば、活性エネルギー線を照射する方法、及び、熱重合法が挙げられる。中でも、加熱が不要であり、室温で重合反応を進行させられるので、活性エネルギー線を照射する方法が好ましい。ここで、照射される活性エネルギー線には、可視光線、紫外線、及び赤外線等の光、並びに電子線等の任意のエネルギー線が含まれうる。
位相差層の製造方法は、前記の工程に加えて、更に任意の工程を含みうる。
例えば、位相差層の製造方法は、液晶性組成物の層に含まれる逆波長重合性液晶化合物を配向させる工程の後、逆波長重合性液晶化合物を重合させる工程の前に、液晶性組成物の層を乾燥させる工程を含んでいてもよい。かかる乾燥は、自然乾燥、加熱乾燥、減圧乾燥、減圧加熱乾燥等の乾燥方法で達成しうる。かかる乾燥により、液晶性組成物の層から、溶媒を除去することができる。
また、例えば、位相差層の製造方法は、製造された位相差層を支持面から剥離する工程を含んでいてもよい。
前記のようにして製造された位相差層は、逆波長重合性液晶化合物を重合させた重合体を含む。この重合体は、逆波長重合性液晶化合物が液晶相における分子の配向を維持したまま重合して得られたものであるので、ホモジニアス配向規則性を有する。ここで、「ホモジニアス配向規則性を有する」とは、重合体の分子のメソゲンの長軸方向が、位相差層の面に水平なある一の方向に整列することをいう。また、前記の重合体の分子のメソゲンの長軸方向は、当該重合体に対応する逆波長重合性液晶化合物のメソゲンの長軸方向となる。さらに、逆波長重合性液晶化合物として化合物(I)を用いた場合のように、位相差層中に配向方向の異なる複数種類のメソゲンが存在する場合は、それらのうち最も長い種類のメソゲンが整列する方向が、前記の整列方向となる。
Re(450)<Re(650) (3)
Re(450)<Re(550)<Re(650) (4)
また、前記の位相差層は、本発明の液晶性組成物を用いて製造されたものであるので、配向性に優れる。ここで配向性に優れる位相差層とは、当該位相差層に含まれる逆波長重合性液晶化合物を重合させた重合体の配向欠陥が少ない位相差層をいう。
このように、前記の位相差層は面状態及び配向性の両方に優れるので、この位相差層を備える円偏光板による反射防止性能を、円偏光板の面内において均一にできる。
本発明の円偏光板は、直線偏光子と、本発明の液晶性組成物から製造された前記の位相差層とを備える。
