Title:
A hardening film formation constituent, material for Distribution , and phase contrast material
Document Type and Number:
Japanese Patent JP6274441
Kind Code:
B2
Abstract:
A cured-film formation composition for forming a cured film having photoreaction efficiency and solvent resistance, and high adhesiveness alignment uniformity, and an orientation material for photo-alignment, and a retardation material formed by use of the orientation material. A cured-film formation composition includes (A) a compound having a photo-aligning group and one substituent selected from a hydroxy group, a carboxy group, and an amino group; (B) a hydrophilic polymer having one or more substituents selected from a hydroxy group, a carboxy group, and an amino group; and (C) a polymer obtained by polymerizing a monomer including an N-hydroxymethyl compound or an N-alkoxymethyl (meth)acrylamide compound, and optionally further a cross-linking catalyst as a component (D). By use of the composition, a cured-film is formed and an orientation material is formed by utilizing photo-alignment technique. A retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.
