1. A silicone composition capable of being cured by both a moisture-curing and ultraviolet curing mechanisms comprising:

  • (a) a reactive organosiloxane prepared by a condensation reaction of a silicone having the general formula ##STR8## where R1 and R2 are each an organo group; and

    a is a number corresponding to a kinematic viscosity of 25-50,000 cSt, measured at 25°

    C., with a vinyl ether silane compound having the general formula ##STR9## where m and n are each an integer of 1 to 5;

    R3 and R4 are each an alkyl group having 1 to 3 carbon atoms or allyl; and

    b is 0 or 1;

    (b) 0-70 parts by weight of a silicone oil per 100 parts by weight of the silicone composition, said silicone oil having a trimethylsilyl group as an end group;

    (c) an catalytic effective amount of a photopolymerization catalyst; and

    (d) a catalytic effective amount of a silicone moisture curing catalyst.
