Abstract
An alkali-developable photopolymerizable composition is disclosed, 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): ##STR1## 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): ##STR2## 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): EQU Ar.sup.2 --R--NH.sub.2 (III) wherein R represents a straight-chain or branched alky…
