ABSTRACT:
An aqueous adhesive composition for wet lamination of substrate layers to form a laminated article includes from about 40 weight percent to about 65 weight percent solids dispersed in an aqueous medium, wherein the solids include a polymer having repeating units derived from a vinyl ester monomer and having a glass transition temperature of about -15.degree. C. to about +15.degree. C.; and from about 0.1 parts by weight to about 40 parts by weight of a plasticizer compound per 100 parts by weight of the polymer. A method for making a laminated article includes applying a wet layer of the aqueous laminating adhesive composition of the to a first substrate layer; covering the wet layer of adhesive composition with a second substrate layer; and drying the layer of adhesive composition to form the laminated article. A laminated article includes two substrate layers bonded together by an interposed layer of the dried adhesive composition.
