Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
53 words
A silicone release paper comprising 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, said barrier coating being formed of a material having a viscosity sufficiently low that the material permeates the porous paper substrate.
Claim 2
Dependent Claim
53 words
A silicone release paper comprising 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, said barrier coating being formed of a material having a viscosity sufficiently low that the material permeates the porous paper substrate.
Claim 3
Dependent Claim
66 words
A self-windable adhesive tape comprising a porous and highly absorbent paper substrate integrated, on one side thereof, with a radiation-insensitive hardened hot melt barrier coating, upon which coating a radiation-cured silicone coating layer has been secured; and carrying a pressure-sensitive adhesive on the other side, said barrier coating being formed of a material having a viscosity sufficiently low that the material permeates the porous paper substrate.
Claim 4
Dependent Claim
66 words
A self-windable adhesive tape comprising a porous and highly absorbent paper substrate integrated, on one side thereof, with a radiation-insensitive hardened hot melt barrier coating, upon which coating a radiation-cured silicone coating layer has been secured; and carrying a pressure-sensitive adhesive on the other side, said barrier coating being formed of a material having a viscosity sufficiently low that the material permeates the porous paper substrate.
