Abstract
A polyurethane hybrid dispersion comprising a carboxylated polyurethane dispersion and a functionalized polymer. The functionalized polymer is the emulsion polymerization product of an ethylenically unsaturated monomer and from 0.1 to 5 pphm of a ureido functional comonomer, wherein the functionalized polymer is prepared in the presence of the carboxylated polyurethane dispersion. he polyurethane hybrid dispersions of the invention exhibit improved wet adhesion to alkyd substrates. Moreover, the polyurethane hybrid dispersions provide the treated substrates with improved solvent resistance.
