Abstract

A material which forms a cured film that has high solvent resistance, the property of aligning liquid crystals, heat resistance, high transparency, and high planarization characteristics and which, when used in forming a cured film, can be dissolved in various solvents usable in a line for producing, for example, a planarization film for color filters. The material is a polyester composition for forming heat-cured films which comprises a polyester as component (A), a crosslinking agent as component (B), and at least one diester compound represented by formula (1) as component (C). (In formula (1), P represents an alicyclic group, a group composed of an alicyclic group and an aliphatic group, or a structure represented by formula (2), and Q represents an alicyclic group or a group composed of an alicyclic group and an aliphatic group. In formula (2), R represents an alkylene group.)

Description

technical field

[0001] The present invention relates to a thermosetting film-forming polyester composition and a cured film obtained from the thermosetting film-forming polyester composition. More specifically, the present invention relates to a polyester composition for forming a thermosetting film and a cured film thereof having high transparency, flattening property, liquid crystal orientation capability, high solvent resistance, and heat resistance, and to the cured Membrane application. This polyester composition for thermosetting film formation is suitable especially 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 solvents and / or heat during the man...
