Abstract

Novel aromatic sulfonium salt compounds of general formula (I), photo-acid generators comprising the same, and photo-polymerizable compositions containing the same, capable of providing stereolithographic resin compositions which do not suffer from the hindrance to curing by oxygen, can easily give shaped articles having desired sizes by virtue of the high accuracy thereof in curing, can attain a satisfactory curing depth owing to the high sensitivity thereof for radiant energy and can be employed for wide usage, such as photoresist and ink for foods-packing medium, since the release of benzene is suppressed; and a stereolithographic process, using said stereolithographic resin composition.
