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.
