The present invention relates to a thermosetting composition, a cured film, and a color filter, which include a polyester amide acid (A), an epoxy compound (B), and a polyfunctional acrylamide compound (C). The polyester amide acid (A) is a multicomponent including X molar tetracarboxylic dianhydride, Y molar diamine, and Z molar in a ratio established by the relationship of the following formula (1) and formula (2) A reaction product of a raw material of a hydroxy compound, the multifunctional acrylamide compound (C) has more than three (meth)acrylamide groups per molecule (CH 2 =CR-CO-NH-; R is Hydrogen or methyl) compounds. A cured film that can be used in various electronic parts and has excellent flatness can be formed from the thermosetting composition of the present invention. 0.2≦Z/Y≦8.0······(1) 0.2≦(Y+Z)/X≦5.0···(2) |
