Zusammenfassung:An ultraviolet curable silicone adhesive composition which contains(A) a linear organopolysiloxane represented by formula (1),        (R1R22SiO1/2)2(Ar2SiO2/2)a(R22SiO2/2)b     (1)(In the formula, R1 represents an alkenyl group; R2 represents a monovalent saturated hydrocarbon group; Ar represents an aryl group; a represents a number of 1-100; b represents a number of 1-1,000; and a/(a+b) represents a number of 0.01-0.4.)(B) an organohydrogen polysiloxane represented by formula (2),        R3cHdSiO(4-c-d)/2     (2)(In the formula, R3 represents a monovalent hydrocarbon group other than an aliphatic unsaturated hydrocarbon group; c represents a positive number of 0.7-2.5; d represents a positive number of 0.01-1; and (c+d) represents a positive number of 0.8-2.7.)(C) a platinum group metal catalyst which is activated by means of light and(D) a compound having one terminal alkenyl group, and which forms a cured product that is suppressed in yellowing and change of hardness even under high temperature conditions.
