固化膜
摘要：
本发明提供在固化膜，所述固化膜是将热固化膜形成用聚酯树脂溶液热固化得到的，所述热固化膜形成用聚酯树脂溶液是将包含下述式(1)所表示的结构单元的聚酯聚合物溶解于溶剂形成的，所述包含下述式(1)所表示的结构单元的聚酯聚合物的重均分子量以聚苯乙烯换算为1,000-30,000，所述固化膜形成后显示高耐溶剂性、液晶取向性、高透明性和高平坦化性。(式中，A、B表示包含环结构的有机基团。)
摘要（英）：

To provide a material which can be formed into a cured film having high solvent resistance, liquid crystal-aligning properties, high transparency and high planarization, and which can be dissolved in a glycol-type solvent and is therefore applicable in the production line for a planarized film of a color filter when used in the formation of a cured film from the material. Disclosed are: a polyester resin solution for the production of a thermally cured film, which comprises a polyester polymer having a structural unit represented by the formula (1); and a cured film, a liquid crystal alignment layer and a planarized film each of which is produced from the polyester resin solution. (1) wherein A and B independently represent an organic group containing a ring structure.
