There is provided a material from which a cured film exhibiting high solvent resistance, liquid crystal-alignment performance, heat resistance and high transparency can be formed. A composition for forming a thermoset film having photo alignment properties, the composition comprising: a component (A) that is an acrylic copolymer having a photodimerizing moiety and a thermal cross-linking moiety; a component (B) that is an acrylic polymer having at least one of a C2-5 alkyl ester group and a C2-5 hydroxyalkyl ester group and at least one of a carboxy group and a phenolic hydroxy group; and a component (C) that is a cross-linking agent.
本发明提供了一种材料,用这种材料可以形成具有高耐溶剂性、液晶配向性能、耐热性和高透明度的固化薄膜。一种用于形成具有光配位性能的热固性薄膜的组合物,该组合物包括:组分(A),即具有光二聚体分子和热交联分子的
丙烯酸共聚物;组分(B),即具有 C2-5 烷基酯基和 C2-5 羟基烷基酯基中的至少一种以及羧基和
酚羟基中的至少一种的
丙烯酸聚合物;以及组分(C),即
交联剂。
