Abstract
Description
また、本発明は、上記光学フィルムおよび光学異方体の調製に使用し得る高分子、当該高分子の調製に使用し得る重合性化合物、当該重合性化合物を含む重合性組成物、並びに、当該重合性化合物および上記光学フィルムの調製に使用し得る化合物に関するものである。
しかしながら、従来の位相差板には、位相差板を通過して出力される偏光が有色の偏光に変換されてしまうという問題があった。これは、位相差板を構成する材料が位相差について波長分散性を有し、可視光域の光線が混在する合成波である白色光に対しては波長ごとの偏光状態に分布が生じることから、入力光を全ての波長領域において正確な1/4λあるいは1/2λの位相差の偏光に調整することが不可能であることに起因する。
このような問題を解決するため、広い波長域の光に対して均一な位相差を与え得る広帯域位相差板、いわゆる逆波長分散性を有する位相差板が種々検討されている。
薄層化の方法としては、低分子重合性化合物を含有する重合性組成物をフィルム基材に塗布して光学フィルムを形成することにより位相差板を作製する方法が、近年では最も有効な方法とされている。そのため、優れた逆波長分散性を有する光学フィルムを形成可能な重合性化合物またはそれを用いた重合性組成物の開発が多く行われている。

(ii)位相差の測定
得られた試料につき、波長400nmから800nm間の位相差を、Mueller Matrix Polarimeter Axoscan(Axometrics社製)を用いて測定した。
(iii)波長分散の評価
測定した位相差を用いて以下のように算出される波長分散比から波長分散を評価した。結果を表2に示す。
(400nmにおける波長分散比:α値)=(400nmにおける位相差値)/(550nmにおける位相差値)
(410nmにおける波長分散比:β値)=(410nmにおける位相差値)/(550nmにおける位相差値)
(420nmにおける波長分散比:γ値)=(420nmにおける位相差値)/(550nmにおける位相差値)
(430nmにおける波長分散比:δ値)=(430nmにおける位相差値)/(550nmにおける位相差値)
(440nmにおける波長分散比)=(440nmにおける位相差値)/(550nmにおける位相差値)
(450nmにおける波長分散比)=(450nmにおける位相差値)/(550nmにおける位相差値)
