<p><P>PROBLEM TO BE SOLVED: To provide a visible light-curing resin composition for fiber-reinforced composites which is useful for a molding method by which the insides or backsides of the fiber-reinforced composites are cured for a short period of time by the irradiation with a low energy visible light. <P>SOLUTION: The visible light-curing resin composition for the fiber-reinforced composites contains components (A), (B) and (C) below in the ratios in specific ranges respectively. (A) is a cationically polymerizable compound. (B) is an iodonium salt expressed by formula (I). In formula (I), R<SP>1</SP>and R<SP>2</SP>are each a hydrogen atom, an alkyl group or an alkoxy group; R<SP>3</SP>, R<SP>4</SP>, R<SP>5</SP>and R<SP>6</SP>are each a hydrogen atom or an alkyl group; X is SbF<SB>6</SB>or B(C<SB>6</SB>F<SB>5</SB>)<SB>4</SB>. (C) is a sensitizer comprising a specific xanthone derivative such as thioxanthone, 2-isopropylthioxanthone, 2-chlorothioxanthone, 2,4-dimethylthioxanthone, 2,4-diethylthioxanthone and 2,4-diisopropylthioxanthone. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
