Abstract: A process for preparing dispersions of particles, especially aqueous dispersions is described. The process relates to a dispersion process where a polar solvent is added during the dispersion process such that the hydrogen bonding solubility parameter component, ?h, of the initial dispersion mixture increases at least 1.5 units. When the polar solvent added is water the dispersion process is called a Solvent-to-Water Process.

Abstract: The present disclosure provides an ink-jet ink made with a pigment dispersion containing a dispersant, and a pigment coated by a polymer that is cross-linked with a crosslinker. The polymer swells in an application medium resulting in improved stability for the pigment dispersion.

Abstract: Inks that contain ionically stabilized dispersions and selected polyurethane ink additives are described. 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, chroma, gloss and especially distinctness of image. The stability of the ionically stabilized dispersions are sufficient for ink jet inks. The polyurethane ink additives are chosen from polyurethanes which are urea terminated or crosslinked.

Abstract: A process for preparing self-dispersing pigment dispersion for ink-jet application is provided in which a carbon black pigment is first oxidized in a gaseous phase and subsequently functionalized in an aqueous environment.
