ABSTRACT:
A photopolymerizable composition is disclosed, comprising the following components (i), (ii) and (iii):
(i) a compound having at least one addition-polymerizable, ethylenically unsaturated bond;
(ii) a compound represented by formula (I): ##STR1## wherein A=represents a substituted or unsubstituted 2(3H)-thiazolylidene or 2-thiazolidinylidene group; --X-- represents --O--, --S--, --NR.sup.2 -- or --CONR.sup.3 --, in which R.sub.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=E represents a substituted or unsubstituted 1,3-dihydro-1-oxo-2H-inden-2-ylidene group; and
(iii) a compound which generates an active radical upon light irradiation in the co-presence of component (ii).
