Abstract
A photopolymerizable composition containing an addition polymerizable compound having at least one ethylenically unsaturated double bond and a photopolymerization initiator is disclosed, wherein the photopolymerizable composition contains at least one compound represented by following general formula (I) or (II) as the photopolymerization initiator: ##STR1## wherein, R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 each represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an allyl group or a substituted allyl group, said R.sub.1 and R.sub.2 may combine with each other to form a ring together with the carbon atoms to which they are bonded; Y represents --O--, --S--, --Se--, --C(CH.sub.3).sub.2 -- or --CH.dbd.CH--; X.sub.1 represents an oxygen atom or a sulfur atom; R.sub.11, R.sub.12, R.sub.17, and R.sub.18 each represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an allyl group, or a substituted allyl group; R.sub.13, R.sub.14, R.sub.15, and R.sub.16 each represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, a halogen atom, a carboalkoxy group, or an alkoxy group; said R.sub.11 and R.sub.15, said R.sub.12 and R.sub.13, said R.sub.15 and R.sub.16, and said R.sub.13 and R.sub.14 each may combine with each other to form a ring together with the carbon atoms to which they are bonded; and X.sub.2 represents an oxygen atom or a sulfur atom.
