Photocurable resin composition for forming overcoats rgb pixels black matrixes or spacers in color filter production, and color filters

摘要

A curable resin composition containing as the binder a fumarate copolymer which is excellent in thermal discoloration resistance and capable of forming details of a color filter, namely, a photocurable resin composition useful in forming overcoats, RGB pixels, black matrixes or spacers in the production of color filters, which contains as the binder a fumarate copolymer having a molecular structure comprising constituent units represented by the general formula (1) and constituent units having acidic functional groups, and preferably further containing constituent units having ethylenically unsaturated bonds: (1) wherein R¹ and R² are each independently branched C_3-8 alkyl which may be substituted, or C_4-8 cycloalkyl which may be substituted.
