This invention provides a process for preparing a stable aqueous emulsion composition which has excellent properties for application as a wet abrasion-resistant paper coating binder. The dispersed copolymer of the aqueous emulsion composition comprises a major proportion of vinyl acetate and a minor proportion of an amino-containing vinyl monomer. An important aspect of the emulsion preparation method is the addition of an aqueous solution of the amino-containing vinyl monomer as a separate feedstream, wherein the amine group in the said vinyl monomer is in the form of an amine-acid salt.
