Patent ID: 8883950

Claim:
A silicone resin composition comprising: a silicon-containing component including a silicon atom to which a monovalent hydrocarbon group selected from a saturated hydrocarbon group and an aromatic hydrocarbon group is bonded and a silicon atom to which an alkenyl group is bonded, wherein the number of moles of alkenyl group per 1 g of the silicon-containing component is 200 to 2000 μmol/g, the silicon-containing component is prepared from a material component comprising: a silicon compound having an alkenyl group and a silanol condensation reactive functional group and being represented by the following general formula (1); a polysiloxane having silanol groups at both ends and being represented by the following general formula (2); an organopolysiloxane having a hydrosilyl group but no alkenyl group; a silicon compound having an epoxy group and a silanol condensation reactive functional group and being represented by the following general formula (5); a condensation catalyst; and an addition catalyst, General Formula (1): (X 1 )— 3 S i— R 1 (1) where, in general formula (1), R 1 represents an alkenyl group and X 1 represents a halogen atom, an alkoxy group, a phenoxy group, or an acetoxy group, X 1 may be the same or different from each other, General Formula (2): where, in general formula (2), R 2 represents a monovalent hydrocarbon group selected from a saturated hydrocarbon group and an aromatic hydrocarbon group, “n” represents an integer of 1 or more, General Formula (5): (X 2 ) 3 Si—R 5 (5) where, in general formula (5), R 5 represents a group having an epoxy structure and X 2 represents a halogen atom, an alkoxy group, a phenoxy group, or an acetoxy group, X 2 may be the same or different from each other.
