(A) (A-1) an alkenyl group-containing linear organopolysiloxane, (A-2) a three-dimensional network organopolysiloxane resin containing R 1 2 R 2 SiO 1/2 units, R 1 3 SiO 1/2 units, and SiO 2 units and containing an alkenyl group, (B) organohydrogenpolysiloxane, (C) a photoactive platinum complex curing catalyst, (D) R 1 2 R 2 SiO 1/2 unit or R 1 2 R 2 SiO 1/2 unit and R 1 3 SiO 1/2 unit, and R 1 SiO 3/2 unit, SiO 2 unit In accordance with the ultraviolet curable organopolysiloxane composition containing an alkenyl group-containing organopolysiloxane oligomer, the ultraviolet curable organopolysiloxane composition of the present invention maintains high strength and heat. Therefore, pattern transfer and printing with high dimensional accuracy are possible. |
