An aryl sulfonium salt, whose photo-induced products are non-benzene, is represented by the formula (I): , wherein Z represents a hydrogen atom or the formula (II): , The substituted groups of R1 to R12 are independently a hydrogen atom, a C1 to C12 alkyl group or a C3 to C12 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. |
