Abstract:
a polymeric colorant includes a pigment having a polymer covalently attached thereto, a dye covalently attached to the polymer, and a dispersant covalently attached to at least one of the pigment, the polymer, and the dye, wherein the dye covalently attached to the polymer includes a reactant coupled to the dye and to the polymer.
