The present invention relates to: A graft copolymer emulsion which is anionically stabilized and which contains an amino functional monomer. The graft copolymer, used in a coating composition, has an average molecular weight of at least about 3,000 and comprises 20 to 95 weight percent of a polymer structure and 5 to 80 weight percent of a macromonomer. The polymer structure 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 functional acid monomer |
