1. An organopolysiloxane composition comprising:

  • (A) 100 parts by weight of an organopolysiloxane represented by formula (1) shown below embedded imagewherein, each R1 represents, independently, either one of a substituted and an unsubstituted monovalent hydrocarbon group of 1 to 15 carbon atoms, and a represents an integer from 10 to 3000;

    (B) 0.1 to 30 parts by weight of an organosilicon compound represented by a formula (2) shown below embedded imagewherein, each R2 represents, independently, any one of a hydrogen atom, a phenyl group and a halogenated phenyl group, each R3 represents, independently, either one of a hydrogen atom and a methyl group, each R4 represents, independently, either one of a substituted and an unsubstituted monovalent hydrocarbon group of 1 to 10 carbon atoms, X represents a hydrolysable group, each Z1 represents, independently, any one of —

    R5

    , —

    R5O— and



    R5(CH3)2SiO—

    where each R5 represents, independently, either one of a substituted and an unsubstituted bivalent hydrocarbon group of 1 to 10 carbon atoms, Z2 represents any one of an oxygen atom, and a substituted and an unsubstituted bivalent hydrocarbon group of 1 to 10 carbon atoms, m represents any one of 0, 1 and 2, and n represents any one of 0, 1 and 2;

    (C) an effective quantity of a condensation curing catalyst; and

    (D) 0.01 to 10 parts by weight of a photopolymerization initiator wherein the parts by weight of the constituents (B) and (D) are based on 100 parts by weight of constituents (A).
