CURABLE RESIN COMPOSITION

摘要

Provided is a curable resin composition which exhibits excellent curability and is good in storage stability. The curable resin composition comprises (a) a polymer having a hydrolyzable silyl group, (b) an acid catalyst, and (c) an onium salt represented by the following general formula (1):;C+A−  (1)wherein C+ is an onium cation, and A− is a hydrogen sulfate anion, a hydrogen sulfite anion, a sulfonate anion represented by R1SO3− wherein R1 represents an alkyl group, perfluoroalkyl group, cycloalkyl group, vinyl group, aryl group, perfluoroaryl group, aralkyl group or halogen atom; or a bis(substituted sulfonyl)imide anion represented by (R2SO2)2N− wherein R2 represents an alkyl group, perfluoroalkyl group, or aryl group; tetrafluoroborate anion, or hexafluorophosphate anion.
