    摘要: A triphenyl sulfonium salt compound shown by the general formula [1] or [3].
    (wherein R 1 and R 2 are each independently a hydrogen atom or a lower alkyl group, provided that at least one of R 1 and R 2 are a lower alkyl group, R 3 s are each independently an alkyl group, n is an integer of 0 to 3, i is an integer of 1 to 3, j is an integer of 0 to 2, provided that i+j=3, Y - is an anion derived from a sulfonic acid shown by the general formula [2]

            R 4 ―SO 3 H     [2]

    [wherein R 4 is an alkyl group or an aryl group which may have as a substituent an alkyl group]).
    (wherein X is a phenyl group which has a substituent at an ortho- and/or a meta-position, m is an integer of 1 to 3, q is an integer of 0 to 2, provided that m+q=3, p is 1 or 2 and Z p- is an anion derived from a carboxylic acid).
