WALLCOVERING MATERIAL CONTAINING PREPASTE ADHESIVES

摘要

A wallcovering material compnsing a substrate having a water remoistenable adhesive on at least one of its surfaces, said adhesive being derived from a stable aqueous emulsion comprising: (I) between about 20 and about 50 weight percent synthetic polymer solids, said solids comprising a copolymer or a terpolymer derived from: (a) between about 60 and about 90 mole percent of a vinyl ester, optionally including vinyl alcohol derived from said vinyl ester; (b) between about 10 and about 40 mole percent of one or more water soluble monomers; and (c) between about 0 and about 10 mole percent of an alkyl acrylate or alkyl methacrylate wherein alkyl represents an alkyl group containing between 1 and 20 carbon atoms; (2) between about 0.5 and about 5.0 weight percent of one or more surfactants or protective colloids; and (3) the balance water; wherein said aqueous emulsion has a viscosity of less than 1000 cps at 25.degree.C and the process for producing the wallcovering is provided.
