Title:
硬化膜形成組成物、配向材および位相差材
Document Type and Number:
Japanese Patent JP6700609
Kind Code:
B2
Abstract:
[Problem] To provide a cured-film-forming composition for providing an alignment material that has excellent vertical alignment properties, has the transparency and solvent resistance required of an optical compensation film, and has adhesiveness to a base material and a polymerizable liquid crystal layer, said alignment material being capable of vertically aligning the polymerizable liquid crystals stably and under low-temperature and short-time firing conditions, even on a resin film. [Solution] Provided is a cured-film-forming composition characterized by containing: (A) a polymer obtained by reacting a carboxyl group of a compound having a carboxyl group and a vertical alignment group with an epoxy group of a polymer having one or more epoxy groups on a side chain or terminal; (B) a crosslinking agent; and one or both of (C) an adhesion promoter and (D) a polymer having a thermal crosslinking group. Further provided are an alignment film characterized by being obtained using the composition, and a phase difference material characterized by being obtained using the composition.
