SULFONIUM SALT, PHOTOACID GENERATOR, PHOTOCURABLE COMPOSITION, AND CURED PRODUCT THEREOF

A sulfonium salt is 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 is characterized in that said sulfonium salt is contained therein.

PHOTOACID GENERATOR, CURABLE COMPOSITION AND RESIST COMPOSITION

PROBLEM TO BE SOLVED: To provide a photoacid generator containing a new sulfonium salt having high photosensitivity to i-line. SOLUTION: A photoacid generator contains a mixed sulfonium salt of a sulfonium salt represented by the following formula (1) and a sulfonium salt represented by the following formula (2), or a sulfonium salt represented by the following formula (2). [R1-R15 are an alkyl group or the like; m1-m9 is an integer of 0-5; X- is a monovalent polyatomic anion]. SELECTED DRAWING: None COPYRIGHT: (C)2019,JPOandINPIT

ONIUM BORATE SALT, ACID GENERATOR, CURABLE RESIN COMPOSITION AND CURED BODY PREPARED THEREWITH

PROBLEM TO BE SOLVED: To provide an onium borate salt and the like having cationic polymerizing performance and crosslinking reacting performance. SOLUTION: An onium borate salt contains onium borate salt (OB1) represented by general formula (1) and onium borate salt (OB2) represented by general formula (2), where the content of (OB2) in (OB1) and (OB2) is 0.01-4 wt.% [(R1)n+1-E]+ [(R2)bB(Ar)4-b]- (1), [(R1)n+1-E]+ [(OH)(R2)bB(Ar)3-b]- (2) [in formulae (1) and (2), E represents an n-valence element of Group VIA to Group VIIA (CAS notation) and n is an integer of 1 or 2; R1 is an organic group bonded to E; R2 is an organic group bonded to B (boron) and b is an integer of 1 to 3; and Ar represents a substituted phenyl group and b is an integer of 1 to 3].
