Abstract
An alkali-developable photopolymerizable composition is comprises (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): ##STR1## wherein Ar.sup.1 is described in the body of the specification; 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): ##STR2## wherein y represents a molar content of the repeating unit in the copolymer, ranging from 0.15 to 0.45, with a primary amine represented by formula (III): EQU 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 is described in the body of the specification at a ratio of from 0.1 to 1.0 molar equivalent of the primary amine to the acid anhydride group of the copolymer. A cured film of the composition is useful as a protective layer for a color filter of liquid crystal display panels.
