Problems solved by technology

However, attempts to create a planarized film for color filters have resulted in problems such as a significant decrease in planarization and transparency.
In addition, although polyimide and polyamic acid are soluble in solvents such as N-methyl-2-pyrrolidone and γ-butyrolactone, they have low solubility in diol-based solvents and ester-based solvents, making it difficult to apply to flat surfaces. Chemical film production line

Abstract

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.

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...
