An aryl sulfonium salt, whose photo-induced products are non-benzene, is represented by the formula (I): n n nwherein Z represents a hydrogen atom or the formula (II): n n nThe substituted groups of R 1 to R 12 are independently a hydrogen atom, a C 1 to C 12 alkyl group or a C 3 to C 12 cyclic alkyl group, and each phenyl group independently has at least one of the alkyl group or the cyclic alkyl group; and X − and Y − are independently an anion. A polymerizable composition containing the aryl sulfonium salt and a polymerization method of the same are provided. |
