Abstract
Disclosed is a curable silicone composition comprising: (A) an organopolysiloxane having a silicon-bonded unsaturated aliphatic radical; (B) an organopolysiloxane having a silicon-bonded mercaptoalkyl radical; and (C) a photoreaction-initiating amount of photoreaction initiator. The photoreaction initiator includes arylcarbonyl phosphine oxide compounds, having a radical selected from the group consisting of substituted and unsubstituted aryl radicals, and another two radicals selected from the group consisting of substituted and unsubstituted monovalent hydrocarbon radicals. The above silicone, composition is efficiently cured by visible light radiation and usable for photo-curable adhesives.
