This invention provides a graft copolymer of at least one acrylic monomer and a random copolymer of a styrene and allyl alcohol, in which at least about 8 percent of the total weight of said graft copolymer is derived from acrylic acid, methacrylic acid, or both. It also provides anionic aqueous dispersions of such graft copolymers and coating compositions containing them.
