Abstract

A cured-film formation composition suitable to form a cured film having liquid-crystal alignment properties. A cured-film formation composition including a component (A) that is one or more monomers having a group having a photo-alignment moiety and thermally reactive moiety, and a polymerizable group; component (B) that is at least one polymer selected from the group of components (B-1) to (B-3) (the component (B-1) being a polymer having, in a quantity of at least two of at least one group selected from the group of hydroxy group, carboxyl group, amide group, amino group, an alkoxysilyl group and group of Formula (2), component (B-2) being a polymer capable of thermally reacting with thermally reactive moiety of component (A) and is self-cross-linkable, and component (B-3) being a melamine formaldehyde resin); and component (C) that is a cross-linking agent; and an orientation material and retardation material which are formed of the cured-film formation composition.

First claim

The invention claimed is:

1. A cured-film formation composition comprising:
a component (A) that is one or more monomers having a group having a photo-alignment moiety and a thermally reactive moiety and a polymerizable group, wherein part of the photo-alignment moiety and part of the thermally reactive moiety optionally overlap each other;
a component (B) that is at least one polymer selected from the group consisting of components (B-1) to (B-3),
the component (B-1) being a polymer having one group selected from the group consisting of hydroxy group, carboxy group, amide group, amino group, an alkoxysilyl group and a group of Formula (2), and at least one other group selected from the group consisting of hydroxyl group, carboxy group, amide group, amino group, an alkoxysilyl group and a group of Formula (2):

wherein R 62 is an alkyl group, an alkoxy group or phenyl group;
the component (B-2) being a polymer that is capable of thermally reacting with a thermally reactive moiety of the component (A) and is self-cross-linkable; and
the component (B-3) being 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 component (B-2),
wherein the group having a photo-alignment moiety and a thermally reactive moiety in the monomers of the component (A) is a group of Formula (1):

wherein
R is a hydroxy group, an amino group, a hydroxyphenoxy group, a carboxyphenoxy group, an aminophenoxy group, an aminocarbonylphenoxy group, a phenylamino group, a hydroxyphenylamino group, a carboxyphenylamino group, an aminophenylamino group, a hydroxyalkyl amino group or a bis(hydroxyalkyl)amino group, wherein a benzene ring in the definitions of these groups is optionally substituted with a substituent, and
X 1 is phenylene group that is optionally substituted with a substituent, and
wherein the polymerizable group in the monomer of the component (A) is at least one selected from the group consisting of (meth)acryloyl group, vinyl group, an allyl group, and maleimide group.

2. The cured-film formation composition according to claim 1 , wherein R is hydroxy group or amino group.

3. The cured-film formation composition according to claim 1 , wherein the monomer of the component (A) is at least one compound of Formulae CIN1 to CIN8.

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

5. The cured-film formation composition according to claim 1 , further comprising, as a component (E), a compound having one or more polymerizable groups and at least one group A selected from the group consisting of hydroxy group, carboxy group, amide group, amino group, an alkoxysilyl group and a group of Formula (2) or at least one group that reacts with the group A.

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

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

8. The cured-film formation composition according to claim 1 , wherein component (B-1) is present.

9. The cured-film formation composition according to claim 1 , wherein component (B-2) is present.

10. The cured-film formation composition according to claim 1 , wherein component (B-3) is present.
