NEW SULPHONIUM SALES, POLYMERISATION INITIATOR, SUSTAINABLE COMPOSITION AND STRENGTHENING PROCEDURES

摘要

The present invention is to provide curable compositions usable appropriately in coatings, adhesives, photoresists, etc. and directed to sulfonium salt compounds represented by general formula ÄIÜ; CHEM wherein R1 and R2 represent each alkyl, hydroxy, alkoxy, alkylcarbonyl, aromatic carbonyl, aromatic thio or halogeno; R3 represents alkyl; R4 represents optionally substituted alkyl, alkenyl or cycloalkyl; m and n are each 0, 1, 2 or 3; and X represents a non-nucleophilic anionic residue; a cationic polymerization initiator containing the compound; and a curable composition which contains the compound and a cationically polymerizable compound optionally together with a sensitizer.
