ALIGNMENT MATERIAL, PHASE-DIFFERENCE MATERIAL, AND CURED FILM–FORMING COMPOSITION

摘要

[Problem] To provide an alignment material, a phase-difference material using said alignment material, and an optical film having, in a surface layer, a cured film that has excellent adhesiveness and liquid crystal alignment properties. [Solution] An alignment material, a phase-difference material, and a cured film–forming composition that is characterized by comprising: (A) at least one compound having a photo-alignable group and a thermally crosslinkable group; (B) a polymer that contains a recurring unit having an N-alkoxymethyl group and a recurring unit having a side chain containing a polymerizable C=C double bond; and (C) at least one polymer selected from the group consisting of: (C-1) a polymer having at least one substituent selected from the group consisting of a hydroxy group, a carboxyl group, amide groups, amino groups, and alkoxysilyl groups; (C-2) a self-crosslinkable polymer having a substituent that can thermally react with component (A); and (C-3) a melamine formaldehyde resin.
