Patent ID: 8492450

Claim:
A siloxane resin composition comprising: (A) polysiloxane obtained from an organosilane comprising at least one carboxyl group, a radical polymerizable group, and wherein the organosilane is selected from the group consisting of Formula (2), Formula (3), Formula (7), Formula (8), Formula (9), and Formula (10): wherein R 4 , R 6 and R 10 are divalent organic groups having 1 to 20 carbon atoms; R 5 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R 7 , R 8 , R 9 are each an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a phenyl group, a phenoxy group, an alkylcarbonyloxy group having 2 to 6 carbon atoms, or substitution products thereof, and at least one of R 7 , R 8 , R 9 is an alkoxy group, a phenoxy group or an acetoxy group; R 11 is an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a phenyl group, a phenoxy group, an alkylcarbonyloxy group having 2 to 6 carbon atoms, or substitution products thereof, wherein R 11 comprises a plurality of units which may be the same or different and at least one unit is an alkoxy group, a phenoxy group or an acetoxy group, and wherein P represents an integer of 1 to 3 and q represents an integer of 2 to 20; R 12 , R 13 , R 14 , R 16 , R 17 , R 18 , R 20 , R 21 , R 22 are each an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a phenyl group, a phenoxy group, an alkylcarbonyloxy group having 2 to 6 carbon atoms, or substitution products thereof; R 15 , R 19 and R 23 are each a single bond or a chain aliphatic hydrocarbon group, a cyclic aliphatic hydrocarbon group, a carbonyl group, an ether group, an ester group, an amide group, an aromatic group, or a divalent group having any thereof, wherein any of these groups may be substituted, and wherein h and k represent each an integer of 0 to 3; and (B) a photo-radical polymerization initiator and (C) a compound having a radical polymerizable group and not having a Si—O—Si bond.
