ABSTRACT:
An aqueous dispersion comprising a polyester having repeat units from at least one difunctional sulfomonomer containing at least one metal sulfonate group attached to an aromatic nucleus wherein the functional groups are carboxyl or hydroxyl, and a polymer having a majority of repeat units from vinyl acetate, wherein this polymer is formed from monomers polymerized in an aqueous dispersion of said polyesters.
