Abstract:
A photopolymerizable composition comprising at least the following ingredients (i) and (ii),(i) a compound having one or more addition-polymerizable ethylenically unsaturated bond(s) and(ii) an oxime ether compound represented by formula (I): ##STR196## wherein R.sup.1 to R.sup.4 each represents an alkyl group which may have substituent(s) or an aryl group which may have substituent(s); Ar represents an aryl group which may have substituent(s); R.sup.1 and R.sup.2 may be bonded to each other to form a ring, and R.sup.3 and R.sup.4 may be bonded to each other to form a ring; Z represents a bivalent hydrocarbon-containing connecting group which may have substituent(s); Y represents a bivalent connecting group or a single bond, said connecting group comprising at least one of the following groups: ##STR197## wherein R.sup.5 represents a hydrogen atom, a hydrocarbon group which may have substituent(s) and unsaturated bond(s), a carbonyl group, or a sulfonyl group, R.sup.6 to R.sup.8, which may be the same or different, each represents a hydrocarbon group which may have substituent(s) and unsaturated bond(s), and T.sup.- represents a univalent anion comprising a halogen atom or a univalent sulfonate anion; andX is a group having an addition-polymerizable group represented by the following formula (I-a): ##STR198## wherein D represents one of the following groups: ##STR199## r.sup.1 to r.sup.3, which may be the same or different, each represents a hydrogen atom, a methyl group, an ethyl group, a phenyl group, a halogen atom, a cyano group, or --C(.dbd.O)--OR.sup.9 ; n represents 0 or 1, provided that when n is 0, not all of r.sup.1 to r.sup.3 are hydrogen atoms; r.sup.4 and r.sup.5, which may be the same or different, each represents a hydrogen atom, a methyl group, an ethyl group, or a phenyl group; and R.sup.9 represents an alkyl group which may have substituent(s) or an aryl group which may have substituent(s) provided that when n is 0 and one of r.sup.2 and r.sup.3 is --C(.dbd.O)--OR.sup.9, R.sup.9 is an alkyl group having two or more carbon atoms which may have substituent(s) or an aryl group which may have substituent(s).
