2096114 9210544 PCTABS00013 Numerous patents teach the use of various complexes of cobalt, rhodium, nickel, palladium, or platinum as catalysts for accelerating the thermally-activated addition reaction (hydrosilation) between a compound containing silicon-bonded hydrogen and a compound containing aliphatic unsaturation. Although platinum complexes and many others are useful as catalysts in processes for accelerating the thermally-activated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for promoting the ultraviolet or visible radiation-activated addition reaction between these compounds are much less common. This invention provides a process for the addition reaction of compounds containing silicon-bonded hydrogen with compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having one diolefin group that is eta-bonded to the platinum atom and two aryl groups that are sigma-bonded to the platinum atom and a sensitizer that is capable of absorbing actinic radiation and is capable of transferring energy to said platinum complex such that the hydrosilation reaction is initiated upon exposure to actinic radiation. The invention also provides compositions for use in the aformentioned process.
