ABSTRACT:
A photopolymerizable composition is disclosed, comprising (i) a compound having at least one addition-polymerizable, ethylenically unsaturated bond; (ii) a compound represented by formula (IA) or (IB): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.9, R.sup.10, R.sup.11 and R.sup.12 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, a hydroxyl group, a substituted oxy group, a mercapto group, a substituted thio group, an amino group, a substituted amino group, a substituted carbonyl group, a sulfo group, a sulfonato group, a substituted sulfinyl group, a substituted sulfonyl group, a phosphono group, a substituted phosphono group, a phosphonato group, a substituted phosphonato group, a cyano group or a nitro group or R.sup.1 and R.sup.2, R.sup.2 and R.sup.3, R.sup.3 and R.sup.4, R.sup.9 and R.sup.10, R.sup.10 and R.sup.11 or R.sup.11 and R.sup.12 may be combined with each other to form an aliphatic or aromatic ring; R.sup.5 represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group; R.sup.6 represents a substituted or unsubstituted alkenylalkyl group, a substituted or unsubstituted alkynylalkyl group, a substituted or unsubstituted alkenyl group or a substituted or unsubstituted alkynyl group; and R.sup.7 and R.sup.8 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group or a substituted carbonyl group, ##STR2## wherein A.dbd. represents a substituted or unsubstituted 2(1H)-pyridylidene group or a substituted or unsubstituted 4(1H)-pyridylidene group; --X-- represents --O--, --S--, --NR.sup.2' -- or --CONR.sup.3' --; R.sup.1', R.sup.2' and R.sup.3' each independently represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an alkenyl group, a substituted alkenyl group, an alkynyl group or a substituted alkynyl group; and .dbd.E represents a substituted or unsubstituted 1,3-dihydro-1-oxo-2H-indene-2-ylidene; and (iii) a compound which generates an active radical upon light irradiation when in the presence of component (ii).
