Abstract
Aqueous thermosetting coating compositions are disclosed in which water has dispersed therein: (1) an acidic hydroxy-functional resin dispersed in water as a salt with a volatile base; (2) a curing agent reactable with the hydroxy groups of the hydroxy-functional resin to cure the same, this curing agent being dispersed in the aqueous medium containing said component (1); and (3) an aqueous emulsion of cross-linked emulsion copolymer comprising, by weight: (A) from 2% to 20% of polyethylenically unsaturated monomer; (B) from 3% to 30% of hydroxy-functional monoethylenically unsaturated monomer (C) from 0% to 20% of monoethylenically unsaturated carboxylic acid monomer; and (D) the balance of the copolymer consisting essentially of copolymerizable nonreactive monoethylenically unsaturated monomer. The emulsion is used to provide the emulsion copolymer in an amount of from 10% to 80% of the total weight of resinous material.
