There is provided 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. The inventive photocurable resin composition is useful in forming overcoats, RGB pixels, black matrixes or spacers in the production of color filters, and 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 C3-8 alkyl which may be substituted, or C4-8 cycloalkyl which may be substituted.
