Abstract
A photopolymerizable composition comprises at least one addition polymerizable compound having at least one ethylenically unsaturated bond and at least one photopolymerization initiator represented by the following general formula (I): ##STR1## wherein R.sub.1 to R.sub.4 independently represent hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, hydroxyl group, a substituted or unsubstituted alkoxy group, or a substituted or unsubstituted amino group with the proviso that R.sub.1 to R.sub.4 may form a non-metallic ring together with the carbon atoms bonded thereto; R.sub.5 and R.sub.6 each represents hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a heteroaromatic group, an acyl group, cyano group, an alkoxycarbonyl group, carboxyl group or a substituted alkenyl group with the proviso that R.sub.5 and R.sub.6 may form a non-metallic ring together with the carbon atoms bonded thereto; X represents O, S, NH or a nitrogen atom having a substituent; and G.sub.1 and G.sub.2 each represents hydrogen atom, cyano group, a substituted or unsubstituted alkoxycarbonyl group,…
