Description
前記染色処理後の少なくとも1つの処理において、処理液中に水溶性酸化防止剤を下記式(1)を満たすように含有させることを特徴とする偏光フィルムの製造方法、に関する。
0.0005≦A×B≦0.03 (1)
〔上記式中、Aは処理浴中の水溶性酸化防止剤の濃度(mol/L)であり、Bはヨウ素をヨウ素イオンに還元する水溶性酸化防止剤の還元力である。〕
0.0005≦A×B≦0.03 (1)
〔上記式中、Aは処理浴中の水溶性酸化防止剤の濃度(mol/L)であり、Bはヨウ素をヨウ素イオンに還元する水溶性酸化防止剤の還元力である。〕
酸化還元反応により、水溶性酸化防止剤の還元力を下記容量滴定法により測定した。
濃度0.1%のヨウ素水溶液(25ml)に、濃度0.5%のデンプン水溶液(キシダ化学(株)製、滴定用)を1〜2ml加えて黒色に着色させた。モル濃度0.01mol/Lの水溶性酸化防止剤水溶液を、前記着色させたヨウ素水溶液中にビュレットを使用して滴下し、水溶液の色が無色になった時の滴定量(ml)を還元力Bとした。
厚み75μmのPVAフィルム(クラレ社製、商品名:VF−PS#7500)を、30℃の純水(膨潤浴)中に1分間浸漬して膨潤させつつ、元長に対して延伸倍率が2.2倍になるように流れ方向に延伸した。その後、PVAフィルムをヨウ素0.045%及びヨウ化カリウム0.315%を含む30℃のヨウ素水溶液(染色浴)中に30秒間浸漬して、染色しながら、元長に対して延伸倍率が3.3倍になるように流れ方向に延伸した。次に、前記フィルムをホウ酸3%及びヨウ化カリウム3%を含む30℃の水溶液に30秒間浸漬しながら、元長に対して延伸倍率が3.6倍になるように流れ方向に延伸した。その後、前記フィルムをホウ酸4%、ヨウ化カリウム5%、及びアスコルビン酸0.0000662mol/Lを含む60℃の水溶液(架橋浴)中に60秒間浸漬しながら、元長に対して延伸倍率が6.0倍になるように流れ方向に延伸した。その後、前記フィルムをヨウ化カリウム3%を含む30℃の水溶液(洗浄浴)中に10秒間浸漬して洗浄した。最後に、前記フィルムを水切りし、緊張を保ったまま60℃のオーブン中で4分間乾燥して偏光フィルムを製造した。
水溶性酸化防止剤の種類及び濃度、並びに水溶性酸化防止剤を添加する処理浴を表1に示すように変更した以外は実施例1と同様の方法で偏光フィルムを作製した。
実施例および比較例で得られた偏光フィルムについて、下記光学特性について評価した。結果を表1に示す。
380〜780nmの波長光における偏光フィルムの分光透過率を、積分球付き分光光度計(日本分光株式会社製、商品名:V7100)を用いて測定した。各直線偏光に対する透過率はグランテラ−プリズム偏光フィルムを通して得られた完全偏光を100%として測定した。測定された分光透過率よりCIE1931 Yxy表色系に従い、C光源2°視野でのY値を算出した。これらを単体透過率(Ts(Y))、平行透過率(Tp(Y))、直交透過率(Tc(Y))とした。
上記測定で得られた単体透過率(Ts(Y))と偏光度(P)の値を下記式に代入して二色比を算出した。
波長410nmにおける偏光フィルムの分光透過率を、積分球付き分光光度計(日本分光株式会社製、商品名:V7100)を用いて測定した。各直線偏光に対する透過率はグランテラ−プリズム偏光フィルムを通して得られた完全偏光を100%として測定した。波長410nmにおけるコントラスト(Cr410nm)は、波長410nmにおける平行透過率(Tp410nm)と波長410nmにおける直交透過率(Tc410nm)の値を下記式に代入することにより算出した。なお、これらの透過率は、JIS Z 8701の2度視野(C光源)により、視感度補正を行ったY値である。
Cr410nm=Tp410nm/Tc410nm
