Abstract: Coating compositions include polymeric particles, a crosslinking agent, and water. The polymeric particles include at least one incorporated monoalkenyl aromatic monomer, at least one incorporated vinyl-containing surfactant monomer, and at least one incorporated acrylic monomer. At least one incorporated acrylic monomer in the polymeric particles includes a hydroxyl, a carboxylic acid, or an amide functional group. The crosslinking agent is an aminoplast resin, preferably an organic aromatic compound that has at least two functional groups selected from (alkoxymethyl)(hydroxymethyl)amines, di(hydroxymethyl)amines, di(alkoxymethyl)amines, or combinations of these. Suitable crosslinking agents include hydroxymethyl and alkoxymethyl derivatives of melamine and other aminoplast resins. Preferably, the coating compositions include a curing catalyst such as an aromatic sulfonic acid or a salt of an aromatic sulfonic acid such as a zinc salt of dinonylnaphthalenesulfonic acid.
