Title:
SULFONIUM SALT, HEAT- OR PHOTO-ACID GENERATOR, HEAT-CURABLE OR PHOTOCURABLE COMPOSITION, AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/020974
Kind Code:
A1
Abstract:
Provided are the following: a sulfonium salt which does not contain a toxic metal and which exhibits higher cationic polymerization performance and crosslinking performance than a tetrakis(pentafluorophenyl)borate salt; a heat- or photo-acid generator characterized by containing the sulfonium salt; an energy ray-curable composition which uses a cationic polymerization initiator (acid generator) because a cured product obtained using the heat- or photo-acid generator contains no residual strong acid following a heat resistance test and therefore does not cause corrosion of a member and does not cause the problem of reduced transparency as a result of resin degradation; and a cured product of the composition. The present invention is a sulfonium salt comprising a sulfonium cation selected from the group represented by general formulae (1), (9), (10) and (11) and a gallate anion represented by formula (a); a heat- or photo-acid generator characterized by containing the sulfonium salt; a heat- or energy ray-curable composition which contains the acid generator and a cationically polymerizable compound; and a cured product obtained by curing same.
