    摘要: The present invention is drawn to pigment suspensions, methods of forming pigment suspensions, and ink sets. The pigment suspension can comprise an aqueous liquid vehicle and a polymer-encapsulated pigment suspended in the liquid vehicle. The polymer-encapsulated pigment can include a pigment core, a passivation layer formed from a passivation component including an amphiphilic polymer and deposited on a surface of the pigment core, and a polymer-encapsulation layer attached to or deposited on the passivation layer.

    摘要: Mixed phthalocyanine and naphthalocyanine water-soluble dyes with near-infrared absorption comprise four isoindole units linked together in a large ring to form a phthalocyanine macrocycle. At least one benzene ring is linked to an isoindole unit and at least one naphthalene ring is linked to another isoindole unit. The remaining two isoindole units each have a benzene ring or a naphthalene ring linked thereto, in any combination. A metal atom is optionally complexed to the phthalocyanine macrocycle.

    摘要: The present disclosure provides encapsulated pigments, ink-jet inks incorporating such pigments, and methods for manufacturing such pigments. In one embodiment, an encapsulated pigment can comprise a pigment, an encapsulating polymer that encapsulates the pigment, and a viscosity modifying polymer particulate that is cross-linked and which is dispersed within the encapsulating polymer.
