ABSTRACT:
A pressure-sensitive adhesive containing a base material therefore comprising an aqueous emulsion of vinyl acetate-ethylene copolymer having an ethylene content of 15 to 40% by weight, preferably 20 to 35% by weight, the benzene-insoluble part of less than 30% by weight, preferably less than 20% by weight, and an intrinsic viscosity of the benzene-soluble part of 0.4 to 1.4 dl/g, preferably 0.6 to 1.0 dl/g, (at 30.degree. C) which is prepared by the emulsion copolymerization of vinyl acetate and ethylene and optionally at least one unsaturated monovinyl monomer in the presence of a protective colloid and a polyoxyethylenic nonionic sulfactant, or a base material comprising a blend of said aqueous emulsion of vinyl acetate-ethylene copolymer as set forth above and an emulsion of an acrylic ester copolymer; and the aqueous emulsion of vinyl acetate-ethylene copolymer useful as the base material for the pressure-sensitive adhesive.
