Abstract
The invention concerns a graft copolymer emulsion which is anionically stabilized and which contains an amino-functional monomer. The graft copolymer, useful in a coating composition, has a weight average molecular weight of at least about 3,000 and comprises 20 to 95 weight percent of a polymer backbone and 5 to 80 weight percent of a macromonomer. The polymer backbone further comprises 0.5 to 30 weight percent of an amino-functional monomer and the macromonomer comprises at least about 5 weight percent of an unsaturated acid-functional monomer.
