ABSTRACT:
Dispersions of an aqueous carrier medium, an insoluble particle, and a graft copolymer dispersant having backbone and side chain portions wherein both portions are prepared from ethylenically unsaturated monomers and either the backbone or sidechain portion is hydrophilic and the other portion is hydrophobic. In a preferred embodiment, the dispersion is formulated as an ink that exhibits excellent resistance to flocculation and provides images with a high color strength and gloss when used in a thermal ink jet printer.
