A dye-containing polarizing film comprising a polarizing film material and a metal-containing dye represented by the following formula (I):
wherein Me is a transition metal selected from copper, nickel, zinc and iron;
Z is hydrogen, lower alkyl, lower alkoxy, sulfo or amino which is unsubstituted or substituted;
Q is a 1-naphthol or 2-naphthol residue which is unsubstituted or substituted and has no or an additional phenylazo or naphthylazo group unsubstituted or substituted and in which a hydroxy group is adjacent to the azo group bonding to the benzene ring having Z and is linked with the transition metal denoted by Me to form the complex;
when Q is the naphthol residue having no additional azo group, then T is naphthyl which is unsubstituted or substituted; and
when Q is the naphthol residue having an additional azo group, the T is a phenyl or naphthyl group which is unsubstituted or substituted, which film exhibits comparable high polarizing activity with film using iodine and superior durability.
一种含染料的偏光膜,由偏光膜材料和下式 (I) 所代表的含金属染料组成:
其中 Me 是选自铜、镍、锌和铁的过渡金属;
Z 是氢、低级烷基、低级烷氧基、磺基或未取代或取代的氨基;
Q 是未被取代或取代的 1-萘酚或 2-萘酚残基,不含或含有一个未被取代或取代的苯基偶氮或萘基,其中羟基与偶氮基相邻,与具有 Z 的苯环结合,并与 Me 所表示的过渡金属相连形成络合物;
当 Q 是没有额外偶氮基的萘酚残基时,T 是未取代或取代的萘基;以及
当 Q 是具有额外偶氮基团的萘酚残基时,T 是未取代或取代的苯基或萘基,这种薄膜具有与使用碘的薄膜相当的高极化活性和出色的耐久性。
