(57) [Summary] [Object] To provide a polymerization initiator for a novel sulfonium salt compound. A sulfonium salt compound of Chemical formula 1 or Chemical formula 2 and a polymerization initiator thereof. [Chemical 1] [Chemical 2] [In the formula, R 1 and R 4 represent a hydrogen atom, an alkyl group, a halogen atom, a carboxyl group or an alkoxycarbonyl group, R 2 and R 5 represent an alkyl group, and R 3 may be substituted. Represents a good phenyl group or naphthyl group, R 6 is an alkenyl group, an α-alkylbenzyl group, represents an α, α-dialkylbenzyl group, an α-phenylbenzyl group, a fluorenyl group, and X represents SbF 6 , AsF 6 , Representing PF 6 or BF 4 ] [Effect] The novel sulfonium salt compound of the present invention is effective as a cationically polymerizable initiator, and can be extremely rapidly polymerized and cured by heat treatment or light irradiation. |
