ABSTRACT:
The invention provides a high-sensitivity ultraviolet-curable organopolysiloxane composition suitable for use as a surface-release treatment of various substrate such as release-paper sheets and the like. The composition comprises, as the essential ingredients, (a) an organopolysiloxane having a viscosity in the range from 50 to 3000 centipoise at 25.degree. C. and containing, in a molecule, at least one (meth)acryloxy-substituted monovalent hydrocarbon group or at least one epoxy- or glycidyloxy-substituted monovalent hydrocarbon group, and (b) a sulfonate compound such as 2-hydroxy-3-oxy-2,3-diphenylpropyl methanesulfonate as the photopolymerization initiator. The sensitivity of the composition to photopolymerization can be further increased by the addition of a specific salt such as sodium hexafluoroantimonate and sodium hexafluorophosphate.
