Abstract
Abstract Release-coated material is produced by applying to a substrate, e.g. paper, a coating of a radiation curable composition comprising (a) an organopolysiloxane containing an average of at least one acryloxy and/or methacryloxy group per molecule, (b) a low molecular weight polyacrylyl crosslinking agent and, optionally, (c) a photosensitizer; and curing the composition on the substrate by exposing it to ionizing radiation or actinic non-ionizing radiation.
