Title:
SULFONIUM SALT COMPOUND AND POLYMERIZATION INITIATOR
Document Type and Number:
WIPO Patent Application WO/1995/024387
Kind Code:
A1
Abstract:
A sulfonium salt compound represented by general formula (I) and a curable composition containing the compound, wherein R1 represents C1-C18 alkyl, hydroxy, C1-C18 alkoxy, C1-C18 alkylcarbonyloxy or halogen, and n represents 0, 1, 2 or 3, provided when n represents 2 or 3, R1's may be different from each other; R2 represents C1-C6 alkyl; R3 and R4 represent each hydrogen or C1-C6 alkyl; R5 and R6 represent each hydrogen, C1-C6 alkyl, hydroxy, C1-C6 alkoxy, C1-C18 alkylcarbonyloxy or aromatic carbonyloxy; R7 represents C4-C20 alkyl or a group represented by general formula (II), wherein R8 represents C1-C18 alkyl, hydroxy, C1-C18 alkoxy, C1-C18 alkylcarbonyloxy, aromatic carbonyloxy or halogen, and m represents 0, 1, 2 or 3, provided when m represents 2 or 3, R8's may be different from each other; and X represents a nonnucleophilic anion residue. As a curable composition particularly comprising a sulfonium salt compound of formula (I), a sensitizer, and a cationically polymerizable compound is cured by heat or light in a short time, it is suitably usable as coating material, adhesive and photoresist.
