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.
