ABSTRACT:
Fluid, stable compositions containing aqueous disperse systems of anionizable material, e.g., a latex of an organic polymer having carboxylate functionality, and a water-dispersible amphoteric polyelectrolyte, e.g., a copolymer of 2-aminoethyl methacrylate and methacrylic acid, are coacervated by maintaining the pH of the composition at a value below the isoelectric point of the amphoteric polyelectrolyte and a value at which the disperse material contains anions.
