Photopolymerizable composition, color filter, and production of color filter

A color filter comprising a layered element having in the following order:

• a transparent substrate, a multicolor image layer comprising a matrix of at least red, green, and blue pixels, and a protective layer comprising a cured product of a photopolymerizable composition comprising, (1) a photopolymerization initiator or a photopolymerization initiator system, (2) an addition polymerizable monomer having an ethylenically unsaturated double bond, and (3) a resin obtained by reacting:
• a copolymer comprising at least a repeating unit represented by formula (I):
• ##STR5## wherein Ar.sup.1 represents a phenyl group or a phenyl group substituted with an alkyl group having from 1 to 4 carbon atoms, an alkoxy group having from 1 to 4 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an aralkyl group having from 8 to 12 carbon atoms, a halogen atom, or a combination of two or more of these substituents;
• and x represents a molar content of the repeating unit in the copolymer, ranging from 0.85 to 0.55, and a repeating unit represented by formula (II):
• ##STR6## wherein y represents a molar content of the repeating unit in the copolymer, ranging from 0.15 to 0.45, and wherein the copolymer has a number average molecular weight of from 500 to 30,000, with a primary amine represented by formula (III):
• Ar.sup.2 --R--NH.sub.2 (III)
• wherein R represents a straight-chain or branched alkylene group having from 1 to 6 carbon atoms;
• and Ar.sup.2 represents an aryl group or an aryl group substituted with an alkyl group having from 1 to 4 carbon atoms, an alkoxy group having from 1 to 4 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an aralkyl group having from 8 to 12 carbon atoms, a halogen atom, or a combination of two or more of these substituents, at a ratio of from 0.1 to 1.0 molar equivalent of the primary amine to the acid anhydride group of the copolymer.
