An acrylate or methacrylate functional copolymerizable monomer which serves as an adhesion for emulsion polymers is disclosed. This monomer is the adduct formed by reacting an aminoalkyl alkylene urea with about 0.9 up to about 1.5 molar proportions of a saturated monoepoxide to consume most or all of one of the two amino hydrogen atoms available, and then reacting with about 0.8 up to about 2.0 molar proportions of a monoisocyanate having a single acrylate or methacrylate group in the presence of at least 0.02%, based on the total weight of hte reactants present, of an inhibitor which retards the free-radical polymerization of ethylenic unsaturation, such as hydroquinone, and phenothiazine.
