SULFONIUM SALT, PHOTOACID GENERATOR, PHOTOCURABLE COMPOSITION, AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/003470
Kind Code:
A1
Abstract:
Because a sulfonium salt that does not contain a toxic metal and that exhibits polymerization performance and crosslinking reaction performance equal to or greater than those of a tetrakis (pentafluorophenyl) borate salt, a photoacid generator characterized in that said sulfonium salt is contained therein, and a cured product in which this substance is used do not leave a strong acid after, in particular, a heat resistance test, the present invention provides an energy-ray curable composition and a cured product that utilize a cationic polymerization initiator (acid generator), which does not cause corrosion of a member and does not cause a problem of transparency reduction due to deterioration of a resin. The present invention is: a sulfonium salt formed of a sulfonium cation selected from a group indicated by general formulas (1), (2), and (3) and a gallate anion represented by formula (a); a photoacid generator that is characterized in that said sulfonium salt is contained therein; an energy-ray curable composition containing said acid generator and a cationically polymerizable compound; and a cured product formed by curing these substances.
