  • Aqueous ionically stablized dispersions
    Publication number: 20080071007
    Abstract: Ironically stabilized dispersions are described that are substantially free of steric stabilization of the pigment. These ionically stabilized dispersions are obtained from polymeric dispersants where the hydrophilic components are minimized. The dispersions can be utilized to prepare ink jet inks which when printed provide advantageous optical density and chroma. Inkjet inks comprising ionically stabilized dispersion are particularly well suited for use in combination with a fixer and the present invention is directed to an inks set with such a combination of inks and to a printing method using this ink set.

  • Aqueous ionically stabilized dispersions
    Publication number: 20070299198
    Abstract: Ionically stabilized dispersions are described that are substantially free of steric stabilization of the pigment. These ionically stabilized dispersions are obtained from polymeric dispersants where the hydrophilic components are minimized. These stabilized dispersions can be utilized to prepare ink jet inks which when printed result in improved optical density and chroma. The stability of the ionically stabilized dispersions are sufficient for ink jet inks.

  • Aqueous ionically stabilized dispersions
    Publication number: 20050090599
    Abstract: Tonically stabilized dispersions are described that are substantially free of steric stabilization of the pigment. These ionically stabilized dispersions are obtained from polymeric dispersants where the hydrophilic components are minimized. These stabilized dispersions can be utilized to prepare ink jet inks which when printed result in improved optical density and chroma. The stability of the ionically stabilized dispersions are sufficient for ink jet inks.
