An object of the present invention is to provide a photopolymerization initiator which has high sensitivity and has no fear of coloring a polymer or contaminating the polymer and equipment. An oxime ester compound represented by the following general formula (I) and a photopolymerization initiator containing the compound as an active ingredient. Embedded image (Wherein, X represents a halogen atom, n represents a number of 1 to 5, R 1 represents R, OR, COR, SR, CONRR ′, CN, and R 2 represents R, OR, COR, Represents SR, NRR ′, R 3 represents R, OR, COR, SR, NRR ′, and R and R ′ represent an alkyl group, an aryl group, an aralkyl group or a heterocyclic group; The aryl group, the aralkyl group or the heterocyclic group may be substituted with a halogen atom or a heterocyclic group, and the alkylene part of the alkyl group and the aralkyl group may be substituted with an unsaturated bond, an ether bond, a thioether bond, or an ester bond. It may be interrupted, and R and R 'may together form a ring.) [Selection diagram] None |
