<p>This invention relates to pigment compositions, e.g., pigmented ink and coating compositions, which comprise pigment particles and a polymer. The polymer can be obtained, for example, by the copolymerization of monomers including: (1) a vinyl halide, e.g., vinyl chloride; (2) a vinyl ester, e.g., vinyl acetate; and (3) a monomer having a sulfuric acid group or a derivative thereof, e.g., an acrylate or methacrylate moiety having a sulfonic acid group or a metal or amine salt thereof. The polymer can impart enhanced dispersion property characteristics to the compositions while also having desirable adhesion and rheological characteristics and thermal stability.</p> |
