Provided is a polyester composite for forming thermoset films, said composite having, after forming a thermoset film, high resistance to solvents and heat, good liquid crystal orientation, high transparency, and high planarizability. Said composite can also, when forming a thermoset film, be dissolved in glycol solvents and lactate ester solvents that can be applied to production lines for planarized color filter films. The composite contains: a component (A) which is a polyester obtained by reacting a tetracarboxylic dianhydride with a diol compound; a component (B) which is an epoxy compound having at least two epoxy groups; and a component (C) which is an amino-group-containing carboxylic compound obtained by reacting a diamine compound with a dicarboxylic anhydride. |
