Abstract
The present invention pertains to an ultraviolet-ray-curable organopolysiloxane composition containing: (A) (A-1) a straight-chain organopolysiloxane containing an alkenyl group, and (A-2) a three-dimensional-network-shaped organopolysiloxane resin containing an RRSiOunit, an RSiOunit, an SiOunit, and an alkenyl group; (B) an organohydrogenpolysiloxane; (C) a photoactive platinum complex curing catalyst; and (D) an organopolysiloxane oligomer containing an RRSiOunit or the RRSiOunit and an RRSiOunit, also containing an RSiOunit, not containing an SiOunit, and also containing an alkenyl group. As a result, this ultraviolet-ray-curable organopolysiloxane composition retains high strength and does extremely well suppressing heat-induced expansion or contraction; hence, it is possible to transfer a pattern and print with high dimensional accuracy.
