PROBLEM TO BE SOLVED: To provide a novel sulfonium compound useful as a thermal acid generator or energy ray acid generator for use as a cationic polymerization initiator.SOLUTION: A thermal acid generator or energy ray acid generator is represented by the general formula (I). [Ris a C1-4 alkyl group; R, R', R'' and Rare each independently H or a C1-4 alkyl group; Ris a C1-4 alkyl group or a substituted/unsubstituted phenyl group; and Xis a superacid anion with a Hammett acidity function of -12 or less (the anion is SbF-, PF-, BF-, B(CF)-, or AsF-).]SELECTED DRAWING: Figure 1 |
