Abstract

A cured-film formation composition that 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. Component (A) contains a compound having a group of Formula [1] below as the photo-aligning group:

where A 1 and A 2 are independently a hydrogen atom or methyl group; and A 3 is a hydroxy group. 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

1 . A cured-film formation composition comprising:
a component (A) comprising a compound having:
a photo-aligning group, and
a group selected from the group consisting of a hydroxy group, a carboxy group, an amino group, and an alkoxysilyl group;
a component (B) comprising a polymer selected from the group consisting of:
a component (B-1): a polymer that has a substituent selected from the group consisting of a hydroxy group, a carboxy group, an amino group, and an alkoxysilyl group,
a component (B-2): a polymer that has a substituent capable of thermally reacting with the component (A) and is self-cross-linkable, and
a component (B-3): a melamine formaldehyde resin; and
a component (C) that is a cross-linking agent, wherein when the component (B) is the component (B-2), the component (C) is optionally the same as the component (B-2), wherein: the component (A) contains a compound having a group represented by Formula [1] below as the photo-aligning group:

where:
A 1 and A 2 are independently a hydrogen atom or a methyl group; and
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; and
hydrogen atoms on the phenylene group and on the phenyl group are independently and optionally substituted with a 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.

2 . The cured-film formation composition according to claim 1 , wherein the compound of the component (A) is a compound having a photo-aligning group of Formula [1] and a hydroxy group.

3 . The cured-film formation composition according to claim 1 , further comprising a component (D) that is a compound having a hydroxy group and an acrylic group, wherein the component (D) is not the same as the compound of the component (A).

4 . The cured-film formation composition according to claim 1 , further comprising a cross-linking catalyst (E).

5 . An orientation material formed of the cured-film formation composition as claimed in claim 1 .

6 . A retardation material comprising a cured film that is obtained from the cured-film formation composition as claimed in claim 1 .

7 . A compound comprising:
a group represented by Formula [1] below; and a group selected from the group consisting of a hydroxy group, a carboxy group, an amino group, and an alkoxysilyl group:

where:
A 1 and A 2 are independently a hydrogen atom or a methyl group; and
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.
