ABSTRACT:
A silicone release paper comprises a porous and highly absorbent paper substrate integrated with a radiation-insensitive hardened hot melt barrier coating, upon which coating a radiation-cured silicone coating layer has been secured. The barrier coating is formed of a material having a viscosity sufficiently low that the material permeates the porous paper substrate. A pressure-sensitive adhesive may be provided on the side of the paper opposite to that on which the silicone coating layer has been secured.
