Abstract
A photopolymerizable composition comprising (1) an addition-polymerizable compound having at least one ethylenically unsaturated double bond and (2) a photopolymerization initiator as essential components, the improvement which comprises the photopolymerization initiator comprising a combination of (a) a 5-isoxazolone represented by the general formula (1) and (b) an aromatic carbonyl compound, a dialkylamino aromatic carbonyl compound represented by any of formulae (2) to (5), a compound represented by the formula (6) or 2-(.alpha.-thioxophenetylidene)-3-methylnaphtho[1,2-d][1,3]-thiazoline: ##STR1## wherein in the formula (1), A.sup.1 and A.sup.2 each represent an alkyl group, an alkylcarbonyl group, an alkoxycarbonyl group, an aryl group, an arylcarbonyl group or a hydrogen atom and may be the same or different; in the formulae (2) to (5) R.sup.1 and R.sup.2 each represent an alkyl group and may be the same or different, R.sup.3 represents an alkyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group or a 5- or 6-membered hetero-aromatic ring, and X represents a substituent having a Hammett's .sigma. value in the range of about -0.9 to +0.7; and in the formula (6) R.sup.4 represents an alkyl group, or an alkenyl group, R.sup.5 represents an alkyl group, an aryl group, a thienyl group or a furyl group, and Z represents an atomic group necessaary to form a nitrogen-containing heterocyclic ring; is disclosed.
