Claim:
1. A UV-curable organopolysiloxane composition comprising: (A) 100 parts by weight of (A-1) 50 to 90% by weight, based on component (A), of a linear organopolysiloxane containing at least two silicon atom-bonded alkenyl groups per molecule, and (A-2) 10 to 50% by weight, based on component (A), of a three-dimensional network-type organopolysiloxane resin comprising R (B) an organohydrogenpolysiloxane containing at least two silicon atom-bonded hydrogen atoms per molecule but no alkoxy groups, in an amount that gives a molar ratio of silicon atom-bonded hydrogen atoms in component (B) to the sum of alkenyl groups in components (A) and (D) of from 0.5 to 6.0; (C) an effective amount of a photoactive platinum complex curing catalyst; and (D) an alkenyl group-containing organopolysiloxane oligomer comprising R
