Claim Text:
1. A UV-curable, adhesive organopolysiloxane composition comprising (A) (A-1) 50 to 90% by weight, based on component (A), of a linear organopolysiloxane having at least two silicon-bonded alkenyl groups per molecule and (A-2) 10 to 50% by weight, based on component (A), of a three-dimensional network organopolysiloxane resin comprising R (B) (B-1) an organohydrogeripolysiloxane containing at least two silicon-bonded hydrogen atoms per molecule, but not alkoxy group, in an amount to give a molar ratio of silicon-bonded hydrogen in component (B-1) to the total of alkenyl in components (A) and (D) of 0.1/1 to 5.0/1, and (B-2) an organohydrogenpolysiloxane containing at least one trialkoxysilyl group bonded to silicon via an alkylene group and at least one silicon-bonded hydrogen atom per molecule, in an amount to give a molar ratio of silicon-bonded hydrogen in component (B-2) to the total of alkenyl groups in components (A) and (D) of 0.05/1 to 2.0/1, with the proviso that a molar ratio of silicon-bonded hydrogen in component (B) to the total of alkenyl in components (A) and (D) is from 0.5/1 to 7.0/1, (C) an effective amount of a photoactive platinum complex catalyst, and (D) a branched organopolysiloxane oligomer comprising R
