Abstract
An amphoteric polymer dispersion obtained in the presence of at least one of starch or a starch derivative by a two-stage polymerization using anionic and cationic monomers is useful as a sizing agent for paper products, as a coating for various substrates, and as a binder in pigment-free coatings or pigment-containing coatings. The dispersion is exceptionally compatible with widely differing sizing agent systems and coating chemicals.
