Document Type and Number:
Japanese Patent JP6451953
Kind Code:
B2
Abstract:
[Problem] To provide a cured film-forming composition that forms a cured film having excellent photoreaction efficiency and solvent resistance, and to provide an alignment material for optical alignment and a phase difference material formed using this alignment material. [Solution] Provided is a cured film-forming composition containing (A) a compound having a photo-aligning group and at least one substituent group selected from among a hydroxyl group, a carboxyl group, and an amino group, (B) a polyamide in which at least some of the nitrogen atoms in the amide groups are alkoxymethylated or alkylthiomethylated, and (C) a crosslinking catalyst. A cured film is formed using this cured film-forming composition, and an alignment material is formed by using a photo-alignment technique. A phase difference material is obtained by coating polymerizable liquid crystals on the alignment material and then curing the polymerizable liquid crystals.
