PROBLEM TO BE SOLVED: To provide a silicon-containing curable composition which has little out-gas component and is excellent in transparency and whose cured product has high heat resistance, is excellent in base resistance and crack resistance and is useful for electric/electronic materials. SOLUTION: The silicon-containing curable composition comprises a prepolymer (A) having two or more Si-H groups in one molecule obtained by hydrosilylation between one or more selected from a component (α) and one or more selected from a component (β) as described below, as a component (A); a cyclic siloxane compound (B) having in one molecule two or more carbon-carbon double bonds having reactivity with an Si-H group, as a component (B); and a hydrosilylation catalyst (C), as a component (C). The component (α) is a cyclic siloxane compound having two or more Si-H groups in one molecule represent by formula (1). The component (β) is a compound having two or more carbon-carbon double bonds having reactivity with an Si-H group. COPYRIGHT: (C)2006,JPO&NCIPI |
