Abstract: An anionically-stabilized aqueous emulsion composition includes a) a first emulsion polymer having a Tg from −60° C. to 40° C.; b) a volatile base; and c) polymeric particles, different from the first emulsion polymer and present in emulsified form. The c) polymeric particles are polyamine graft copolymers, in which vinyl monomers form a polymer grafted to a water-soluble amino-group containing polymer. The anionically-stabilized aqueous emulsion composition may have a pH of from 8 to 11.
