Patent number: 4588757Abstract: A method of forming an aqueous emulsion laminating adhesive having an extended pot life is disclosed in which monoethylenically unsaturated monomers are polymerized to form a copolymer having a glass transition temperature in the range of about -10.degree. C. to about -50.degree. C. The polymerization is carried out in aqueous emulsion in the presence of emulsified epoxy resin in an amount of from about 2% to about 60%, based on the weight of the monomers which are copolymerized. An aqueous emulsion of amine-functional resin is then mixed into aqueous emulsion containing copolymer and epoxy resin formed by the aqueous emulsion copolymerization to provide a weight ratio of amino hydrogen atoms to oxirane groups of from about 0.1 to about 1.0.Type: GrantFiled: February 11, 1985Date of Patent: May 13, 1986Assignee: DeSoto, Inc.Inventors: Ralph L.
