  • Patent number: 5312863
    Abstract: A novel coating composition, exhibiting improved adhesion to anionic substrates and a process for its preparation and use, is disclosed. The coating contains an aqueous dispersion of a cationic polymeric binder. The polymeric binder is preferably prepared by the polymerization of at least one monoethylenically unsaturated monomer, having amine functionality, in the presence of at least one nonionic or amphoteric surfactant, followed by the subsequent neutralization of the polymer using selected acids. Coatings containing the cationic latex polymeric binder and selected cationic pigment dispersants are provided.
