    Novel aromatic sulfonium compounds, photoacid generators comprising the same, photopolymerizable compositions containing the same, stereolithographic resin compositions, and stereolithographic process
    WO 1999028295 A1
    Abstract
    Novel aromatic sulfonium compounds of general formula (I), photoacid generators comprising the same, and photopolymerizable 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, and can attain a satisfactory curing depth owing to the high sensitivity thereof for radiant energy; and a stereolithographic process.
