摘要： Provided is an ultraviolet-curable silicone composition including: (A) a non-terminal epoxy group-containing organopolysiloxane, (B) an organopolysiloxane containing epoxy groups at the two terminals of the molecular chain, and an onium salt photoinitiator capable of generating cations upon irradiation with ultraviolet light. The silicone composition of the present invention yields a cured film that exhibits excellent ultraviolet-curability and can be readily peeled from a pressure-sensitively adhesive material. In particular, the silicone composition yields a cured film that exhibits a tight release force relative to pressure-sensitive adhesives such as acrylic-based pressure-sensitive adhesives, and also exhibits minimal fluctuation in the release force.

摘要： The invention provides a silicone composition curable by ultraviolet irradiation to give a cured film on a substrate surface exhibiting surface releasability against sticky surfaces. Advantageously, peeling works of a sticky surface from the cured surface of the inventive composition can be carried out with no or little generation of peeling noises which deteriolate the working environment. The composition comprises three different types of organopolysiloxane compounds of which the first is a so-called MQ siloxane, the second is a linear or cyclic diorganopolysiloxane having epoxy-containing substituents on the silicon atoms other than the chain terminal silicon atoms and the third is a straight or branched linear organopolysiloxane compound substituted by an epoxy-containing substituent on each of the chain terminal silicon atoms in a specified weight proportion of these three. The composition contains an onium salt compound as a photoreaction initiator to promote the ultraviolet-induced curing.
