The present invention is directed to improved aqueous dispersions containing polyurethane/vinyl polymers and to a method for making such aqueous polyurethane-vinyl polymer dispersion. The aqueous dispersions comprise a urethane prepolymer having carboxyl functionality therein and a vinyl monomer polymerized therewith. The improvement in these dispersions resides in shelf-stability and self crosslinkability at low temperature with the polyurethanes having the carboxyl functionality in quaternary form and such dispersions containing polymer having pendant epoxide groups. When the aqueous dispersions are cast as a film and the water removed, crosslinking between the carboxyl group and epoxide group occurs.

The aqueous polymer dispersion is prepared by
