Abstract

This invention provides radiation-curing coating compositions comprising a mixture of organopolysiloxanes modified laterally and terminally with acrylic groups, which exhibit markedly improved adhesion to a variety of substrates following curing and for which there is little or no change in the adhesiveness on storage for prolonged periods.
