AZO COMPOUND, COMPOSITION FOR OPTICAL ALIGNMENT FILM USING SAME, AND METHOD FOR PRODUCING OPTICAL ALIGNMENT FILM

摘要

An azo compound of the present invention is represented by the general formula (1):
(wherein, R 1 and R 2 each independently represents a hydroxy group, or a polymerizable functional group selected from the group consisting of a (meth)acryloyl group, a (meth)acryloyloxy group, a (meth)acrylamide group, a vinyl group, a vinyloxy group, and a maleimide group; X 1 represents single bond when R 1 is a hydroxy group and represents a linking group represented by -(A 1 -B 1 ) m - when R 1 is a polymerizable functional group; X 2 represents a single bond when R 2 is a hydroxy group and represents a linking group represented by -(A 2 -B 2 ) n - when R 2 is a polymerizable functional group; R 3 and R 4 each independently represents -OR 7 , a hydroxyalkyl group having 1 to 4 carbon atoms, or - CONR 8 R 9 ; and R 5 and R 6 each independently represents a carboxy group, a sulfo group, a nitro group, amino group, or a hydroxy group).
