    摘要: Water-based pigmented inks are disclosed. Such inks are formed from water-based dispersions of pigment particles having novel dispersants therein. The dispersions are formed from the reaction product of an amino acid compound with a nitrogen reactive compound with subsequent hydrolysis providing the capability of the dispersant to hydrophobically interact with the pigment particles. The resultinginks are well-suited for use in ink jet and other printing applications.

    摘要: The toner particles of this invention comprise pigment and a resin. The resin comprises a novel polymer formed from ethylenically unsaturated monomers, macromeric moieties that render the resin dispersible in hydrocarbon solvents, and a surface-release promoting moiety. When used for toner particles the polymer further comprises charge directing chelating moieties. The toner particles also include a charge director, preferably a metal cation. The toner particles, when dispersed in a carrier liquid, are useful as liquid toners for electrographic or electrophotographic processes.
