Abstract
A curable resin composition is provided which uses a fumarate copolymer which is excellent in thermal discoloration resistance as a binder component and is capable of forming details of a color filter. The curable resin composition of the present invention is a photocurable resin composition for forming a protective layer, RGB pixels, a black matrix or a spacer of a color filter, and contains as a binder component a fumarate copolymer having at least a molecular structure wherein a constituent unit represented by the following Formula 1 and a constituent unit having an acidic functional group(s) are linked, preferably further having a constituent unit with an ethylenically unsaturated bond:wherein, each of R1 and R2 is independently a branched C3-8 alkyl group which may be substituted, or a C4-8 cycloalkyl group which may be substituted.
