Abstract
Abstract A porous web-like substrate is treated with an adhesive containing a filler which increases the viscosity of the adhesive thereby inhibiting flow of the adhesive through the pores of the substrate, and increases the amount of the adhesive retained on the surface of the substrate. In a preferred embodiment a high surface area siliceous material is added to a carboxylated styrenebutadiene latex adhesive to improve adhesion of porous substrates.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
61 words
A laminate consisting of at least one substrate of porous web-like material bonded to at least one other web-like substrate by an adhesive composition consisting essentially of a carboxylated styrene-butadiene and at least one of casein and soy bean protein adhesives said composition having incorporated therein up to about 5 percent by weight of a high surface area asbestos filler material.
Claim 2
Dependent Claim
61 words
A laminate consisting of at least one substrate of porous web-like material bonded to at least one other web-like substrate by an adhesive composition consisting essentially of a carboxylated styrene-butadiene and at least one of casein and soy bean protein adhesives said composition having incorporated therein up to about 5 percent by weight of a high surface area asbestos filler material.
Claim 3
Independent Claim
85 words
A method for bonding a porous web-like substrate to another substrate comprising applying to the surface of one of said substrates an adhesive composition in a fluid state said adhesive consisting essentially of carboxylated styrene-butadiene and at least one of casein and soy bean adhesives said composition having incorporated therein up to about 5 percent by weight of a high surface area asbestos filler material, pressing said substrates into contact enclosing said filled adhesive composition and allowing said adhesive composition to set producing a laminate.
