Abstract
Abstract A method of producing silicone-coated release papers, labels and tapes and the like in an in-line procedure through the use of a radiation-insensitive hot melt barrier coating on poor porous and highly absorbent paper substrates, and upon which barrier coating a silicone coating is radiation cured.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
A method of producing a silicone coating on a porous and highly moisture-absorbent paper substrate in an in-line procedure, comprising, in one pass, applying a barrier coating of radiation-insensitive hot melt material to one side of the substrate, said material having a low enough viscosity to permit the material to permeate the porous paper substrate; following integrating with and setting of such coating on the substrate, applying thereupon, in-line, a coating of radiation-curable silicone; and radiation-curing said silicone coating upon and to the set barrier coating.
Claim 2
Independent Claim
86 words
A method of producing a silicone coating on a porous and highly moisture-absorbent paper substrate in an in-line procedure, comprising, in one pass, applying a barrier coating of radiation-insensitive hot melt material to one side of the substrate, said material having a low enough viscosity to permit the material to permeate the porous paper substrate; following integrating with and setting of such coating on the substrate, applying thereupon, in-line, a coating of radiation-curable silicone; and radiation-curing said silicone coating upon and to the set barrier coating.
Claim 3
Dependent Claim
28 words
A method as claimed in claim 1 in which the substrate is inverted and a pressure-sensitive hot melt adhesive is applied to the other side of the substrate.
Claim 4
Dependent Claim
54 words
A method as claimed in claim 1 in which a pressure-sensitive adhesive is applied to and set on another substrate, and said other substrate is laminated to the silicone-coated surface of the first-named substrate to permit winding of the same and subsequent stripping away and releasing of said other substrate from said first-named substrate.
Claim 5
Dependent Claim
16 words
A method as claimed in claim 1 in which said hot melt material has wax-like properties.
Claim 6
Dependent Claim
24 words
A method as claimed in claim 4 in which the viscosity of said hot melt material is of the order of 10 5 centipoise.
