    摘要: A curable silicone composition based on an organopolysiloxane having a cyclotrisiloxane structure quickly cures by brief heating or ultraviolet exposure. It further contains an acid, acid generator, base or base generator or an oniom salt photo-initiator as a curing agent. The cured product has release property from adhesive substance which remains unchanged with the lapse of time and good mold release properties, and thus provides a lightly releasable cured film. The composition is widely used as adhesive tape backing agents, mold release agents, protective coating agents, water and oil repellent agents, and paint base.

Thus, the composition comprises(a) an organopolysiloxane having at least two mercaptoalkyl, e.g. mercaptopropyl, groups bonded to the silicon atoms in a molecule,(b) an organopolysiloxane having at least two alkenyl, e.g. vinyl groups directly bonded to the silicon atoms in a molecule, and(c) an organopolysiloxane having at least one benzoin group ##STR1## where Ph is a phenyl group, bonded to the silicon atom in a molecule, which component (c) serves as a photosensitizing ingredient. Alternatively, the inventive composition comprises (a) a mercaptoalkyl-containing organopolysiloxane as above and (b') an organopolysiloxane having, simultaneously, at least two alkenyl groups and at least one benzoin group directly bonded to the silicon atoms in a molecule, which component (b') serves both as the crosslinking agent and as the photosensitizing ingredient simultaneously. Owing to the unquestionable affinity of the photosensitizing ingredient with the other components, the inventive compositions have very high sensitivity in photocuring along with several other advantageous characteristics.
