PHOTOSENSITIVE RESIN, PROCESS FOR PRODUCING THE SAME AND PHOTOSENSITIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin which does not deteriorate re-solubility in a solvent and storage stability to further improve the adhesion to a substrate and is particularly suitably used in producing color filters.

SOLUTION: The photosensitive resin is a carboxyl group-containing polymer into which a reactive unsaturated group has been introduced and is constituted of a polymer obtained by reacting a polymer obtained by reacting a carboxyl group-containing polymer with an epoxy group-containing reactive unsaturated monomer to introduce a reactive unsaturated group thereinto with a polybasic acid anhydride and an epoxy group-containing reactive unsaturated monomer to further introduce a reactive unsaturated group thereinto.
