ABSTRACT:
A stable aqueous dispersion of a room temperature curing polymer effective for forming films resistant to water and organic solvents, said polymer being a water-dispersible vinyl addition polymer containing a sufficient proportion of pendant N-methylolhydrazide groups to cause the polymer to cure in situ on a substrate when said dispersion is applied to the substrate and dried at ambient temperature. The polymer preferably sufficient pendant carboxylic salt groups to render the polymer water-dispersible or water soluble.
