Abstract

A photopolymerizable composition for forming protective layers of color filters, which comprises: PA1 (1) a photopolymerization initiator or a photopolymerization initiator system, PA1 (2) an addition-polymerizable monomer having an ethylenically unsaturated double bond, and PA1 (3) a resin produced by reaction of an anhydride-containing copolymer having a number average molecular weight of 500 to 30,000 which contains repeating units represented by at least formulas (I), (II) and (III), respectively, with a primary amine represented by formula (IV) with the ratio of the primary amine to the copolymer being 0.1 to 1.0 equivalent per equivalent of the anhydride in the copolymer: ##STR1## wherein the variables in formulas (I), (II), (III) and (IV) are defined in the specification.
