Abstract: The present invention provides a polarizing film having a high dichroic ratio. The polarizing film contains a disazo compound represented by the following general formula (1). In the general formula (1), Q1 represents a phenyl group having at least one —SO3M group; Q2 represents a naphthylene group having at least one —SO3M group; X represents an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a thioalkyl group having 1 to 4 carbon atoms, a halogeno group, or a polar group; subscript k denotes the number of substitutions of X and represents an integer of 0 to 5; and M represents a counter ion, where when k is an integer of 2 or more, Xs are the same or different.

Abstract translation: 本发明提供了具有高二向色比的偏振膜。 偏振膜含有由以下通式（1）表示的双偶氮化合物。 在通式（1）中，Q1表示具有至少一个-SO 3 M基团的苯基; Q2表示具有至少一个-SO 3 M基团的亚萘基; X表示碳原子数1〜4的烷基，碳原子数1〜4的烷氧基，碳原子数1〜4的硫代烷基，卤代基或极性基; 下标k表示X的取代数，表示0〜5的整数。 M表示抗衡离子，当k为2以上的整数时，X相同或不同。

Abstract: The present invention provides a polarizing film having a high dichroic ratio. The polarizing film includes a disazo compound represented by the following general formula (1). In the general formula (1), Q represents a substituted or unsubstituted phenyl group or a substituted or unsubstituted phenyl group having a heterocyclic ring; non-adjacent carbon atoms of the phenyl group may be substituted with nitrogen atoms; R1 represents an alkyl group; R2 represents a hydrogen, an acetyl group, or a substituted or unsubstituted benzoyl group; n represents 1 or 2; and M represents a counter ion.
