COMPOSITION FOR PHOTO-ALIGNMENT FILM, OPTICALLY ANISOTROPIC MATERIAL AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a composition for photo-alignment films which is characterized by containing a compound represented by the general formula (1) below and a compound having a hydrophilic group and a (meth)acryloyloxy group. Also disclosed are an optically anisotropic material wherein a photo-alignment film made of such a composition is used, and a method for producing such an optically anisotropic material. [Chemical formula 1] (1) (In the formula, R¹ and R² independently represent a hydrogen atom, a halogen atom, a carboxyl group or an alkali metal salt thereof, a halogenated methyl group, a halogenated methoxy group, a cyano group, a nitro group, -OR⁵, a hydroxylalkyl group having 1 4 carbon atoms, -CONR⁶R⁷- or a methoxycarbonyl group; and R³ and R⁴ independently represent a carboxyl group or an alkali metal salt thereof, a sulfo group or an alkali metal salt thereof, a nitro group, an amino group, a carbamoyl group, an alkoxycarbonyl group, a sulfamoyl group or a hydroxyl group.)
