Abstract

A cured-film formation composition to form a cured film having excellent liquid-crystal alignment properties, orientation material, and retardation material by use of the orientation material. A cured-film formation composition includes: (A) one or more compounds having a photo-aligning group and hydroxy group, etc.; (B) a polymer having at least one substituent from the group of a hydroxy group, carboxy group, amino group, and alkoxysilyl group, and the like; and (C) a cross-linking agent, the component (A) contains at least a compound having a group of Formula [1] below as the photo-aligning group:

(in the Formula, A 1 and A 2 are independently a hydrogen atom or methyl group; and A 3 is a hydroxy group, etc.). A cured-film is formed from the cured-film formation composition, and orientation material is formed by use of photo-alignment technique. A retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.

First claim

The invention claimed is:

1. A compound of Formula [2]:

where:
A 1 and A 2 are independently a hydrogen atom or a methyl group;
A 3 is a hydroxy group, a mercapto group, an amino group, a C 1-10 alkoxy group, a C 1-10 alkylthio group, a C 1-10 alkylamino group, a phenoxy group, a phenylthio group, a phenyl amino group, a biphenyl amino group, a phenyl group, or a biphenyl group, wherein hydrogen atoms on the phenylene group and on the phenyl group are independently and optionally substituted with at least one substituent selected from the group consisting of a C 1-10 alkyl group, a C 1-10 alkoxy group, a halogen atom, a cyano group, and a nitro group; and
n is an integer of 2 to 20.
