Aqueous adhesive emulsions based on aqueous emulsion copolymers of vinyl esters, such as vinyl acetate, with ethylene in the presence of an hydroxy functional protective colloid, are provided with increased gel content which provides superior resistance to cold flow and improved adhesion, by the inclusion in the copolymer of a monoethylenic amide monomer, especially acrylamide.
