-1- ABSTRACT OF THE DISCLOSURE This invention relates to a process for reacting a compound containing silicon-bonded hydrogen with a compound containing aliphatic unsaturation in the presence of actinic radiation and to compositions that contain an actinic radiation-sensitive catalyst that are used in the process. Although many platinum complexes 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 accelerating the ultraviolet radiation activated addition reaction between these compounds, using a platinum complex as a catalyst, are not known. The ultraviolet radiation activated addition radiation can be conducted in the presence of a platinum complex having an ultraviolet displaceable group, e.g. a ( -diolefin)( -aryl) platinum complex. This process is useful for the in situ curing of a polymeric silicone composition to a solid surface, particularly one which is heat-sensitive.
