ABSTRACT:
The invention provides a silicone-coated release paper having a coating surface film of an organopolysiloxane composition curable by irradiation with ultraviolet light or electron beams to give a fully cured film resistant to migration of the organopolysiloxane constituents therefrom on to other surfaces in contact therewith. The composition comprises (a) a diorganopolysiloxane terminatd at both molecular chain ends each with a divinylmethylsilyl group or trivinylsilyl group, (b) an organohydrogenpolysiloxane having at least 2 hydrogen atoms directly bonded to the silicon atoms in a molecule, (c) a catalytic amount of a platinum or rhodium catalyst and, optionally, (d) a compound of a rare earth element such as ceric oxide.
