Abstract:

Coating compositions include polymeric particles, an isocyanate-containing crosslinking agent, and water. The polymeric particles include at least one incorporated monoalkenyl aromatic monomer, at least one incorporated vinyl-containing surfactant macromonomer, and at least one incorporated acrylic monomer. At least one incorporated acrylic monomer in the polymeric particles includes a hydroxyl, amine, or a carboxylic acid functional group. The crosslinking agent is an isocyanate-containing organic compound or such a compound with blocked isocyanate groups. Coating compositions may be deposited and cured by heating to form crosslinked coating compositions. Such crosslinked coating compositions exhibit excellent solvent resistance.
