Abstract:
A silicone resin composition formulated from a silicone resin comprising mainly polyorganosilsesquioxane which is represented by formula (1)[RSiO3/2]nâ€ƒâ€ƒ(1) (wherein R is an alkyl group containing 1 to 6 carbon atoms or phenyl group) and contains a cage structure in us structural unit and the siloxy (SiOâ€”) groups of which are at least partly linked to a triorganosilyl group represented by the following general formula (2) (wherein X is a reactive functional group represented by â€”R1â€”OCOâ€”CR2&boxH;CH2, â€”R1â€”CR2&boxH;CH2 or â€”CH&boxH;CH2; R1 is an alkylene group, an alkylidene group or phenylene group; and R2 is a hydrogen atom or an alkyl group)and an unsaturated compound which contains at least one unsaturated group represented by â€”R3â€”CR4&boxH;CH2 or â€”CR4&boxH;CH2 (wherein R3 is an alkylene group, an alkylidene group or â€”OCOâ€” group; and R4 is a hydrogen atom or an alkyl group) in the molecule and is radically copolymerizable with the silicone resin at a weight ratio of 1:99 to 99:1, wherein 10 to 100 wt % of the unsaturated compound which is radically copolymerizable with the silicone resin is an alicyclic unsaturated compound represented by the following general formula (3) (wherein Z is (3a) or (3b) shown below; and R is a hydrogen atom or methyl group)
