Abstract

Disclosed is a material which enables pattern formation in an alkaline developer, and shows high solvent resistance, liquid crystal orientation, heat resistance, high transparency, and high planarity after being formed into a cured film, and can be dissolved in a glycol solvent which can be applied to the production line of a planarized film of a color filter while being formed into a cured film. Specifically disclosed is a photosensitive polyester composition for use in forming thermally cured film, containing component (A), component (B), component (C), and component (D): component (A): a modified polyester obtained by reacting a compound having a functional group selected from a glycidyl group and an isocyanate group with a polyester containing a structural unit represented by formula (1); component (B): an epoxy compound having two or more epoxy groups; component (C): an amino group-containing carboxylic acid compound obtained by reacting a diamine compound with dicarboxylic acid dianhydride; and component (D): 1,2-quinone diazide compound. In formula (1), A and B each independently represent an organic group containing a cyclic structure.

Description

technical field [0001] This invention relates to the photosensitive polyester composition for thermosetting film formation, and the cured film formed from this composition. More specifically, the present invention relates to a photosensitive polyester composition for forming a thermosetting film and a cured film thereof capable of forming a cured film having high transparency, flattening property, liquid crystal orientation ability, and high solvent resistance, and Applications involving the cured film. This photosensitive polyester composition for thermosetting film formation is especially preferable as a color filter overcoat agent which has a liquid-crystal orientation function in a liquid crystal display. Background technique [0002] In general, optical devices such as liquid crystal display elements, organic EL (electroluminescent) elements, and solid-state imaging elements are provided with a protective film to prevent the element surface from being exposed to solven...
