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 R and R are each independently branched C3-8 alkyl which may be substituted, or C4-8 cycloalkyl which may be substituted. L'invention concerne une composition de résine durcissable contenant en tant que liant un copolymère de fumarate présentant une excellente résistance à la décoloration thermique et pouvant former les détails d'un filtre coloré, à savoir, une composition de résine photodurcissable utilisée dans la formation de revêtements, de pixels RGB, de matrices noires ou d'éléments de séparation dans la production de filtres colorés, et contenant en tant que liant un copolymère de fumarate présentant une structure moléculaire comprenant des unités constitutives représentées par la formule générale (1) et des unités constitutives contenant des groupes fonctionnels acides comprenant des liaisons non saturées en éthylène, formule dans laquelle R et R sont chacun indépendamment un alkyle C3-8 ramifié pouvant être substitué ou un cycloalkyle C4-8 pouvant être substitué.
