  • Patent number: 4963438
    Abstract: A method is disclosed for coating sheet-like supports by applying curable organopolysiloxanes, which have been modified with (meth)-acrylate ester groups, on the surface of the support and curing the modified organopolysiloxanes by the action of polymerizing high-energy radiation. Polysiloxanes with hydroxy-functional groups are employed for this purpose, which are obtained by reaction with, based on the hydroxyl groups, 0.4 to 0.9 molar amounts of (meth)acrylic acid and up to 0.6 molar amounts of monocarboxylic acids, which are free of double bonds (sum of the acids.ltoreq.1 molar).
