Abstract: The oxime ester compound of the present invention is represented by general formula (I) below and useful as a photopolymerization initiator. The photopolymerization initiator comprising the oxime ester compound of the present invention as an active constituent has high sensitivity and causes no concern about coloration of the resultant polymerized material or contamination of the polymerized material or apparatuses. (In the formula, X represents a halogen atom or an alkyl group. R 1 , R 2 , and R 3 each independently represent R, OR, COR, SR, CONRR', or CN, wherein R and R' each represent an alkyl group, an aryl group, an aralkyl group, or a heterocyclic group; these groups may be substituted with (a) halogen atom(s) and/or (a) heterocyclic group(s); the alkylene moiety in the alkyl or aralkyl group may be interrupted by (an) unsaturated bond(s), (an) ether bond(s), (a) thioether bond(s), or (an) ester bond(s); and R and R' may bond together to form a ring. Y 1 represents an oxygen atom, a sulfur atom, or a selenium atom; A represents a heterocyclic group; m represents an integer of 0 to 4; p represents an integer of 0 to 5; and q represents 0 or 1.)

Abstract: Disclosed is an oxime ester compound which is represented by the general formula (I) below and useful as a photopolymerization initiator. A photopolymerization initiator containing such an oxime ester compound as an active constituent is highly sensitive and does not color the polymerization product or contaminate the polymerization product and apparatus. (I) (In the formula, X represents a halogen atom or an alkyl group; R1, R2 and R3 independently represent R, OR, COR, SR, CONRR' or CN wherein R and R' respectively represent an alkyl group, an aryl group, an aralkyl group or a heterocyclic group which may be substituted by a halogen atom and/or a heterocyclic group, the alkylene section of the alkyl group and aralkyl group can be interrupted by an unsaturated bond, an ether bond, a thioether bond or an ester bond, and R and R' may combine together to form a ring; Y1 represents an oxygen atom, a sulfur atom or a selenium atom; A represents a heterocyclic group; m represents an integer of 0-4; p represents an integer of 0-5; and q represents 0 or 1.)
