摘要:
The present invention is drawn to steric stabilized latex particulates, methods of forming such particulates, inks containing such particulates, and methods of ink-jetting inks containing such particulates. A steric stabilized latex particulate for use in an ink-jet ink can comprise a random copolymer of a steric stabilization oligomer and a hydrophobic monomer.

An inkjet printing composition comprises an aqueous liquid vehicle; at least one pigment having a concentration of about 1 to 5 wt %; and a latex polymer having a concentration of about 2.5 to 8 wt % and comprising a polymerized mixture of styrene, butyl acrylate, at least one of methacrylonitrile and acrylonitrile, methacrylic acid, and ethylene glycol dimethacrylate. An inkjet ink printing system comprises a vinyl medium; the at least one inkjet printing composition; and a heating device, wherein the system is configured such that upon applying heat from the heating device to the inkjet ink printed on the vinyl medium, the latex particles fuse, thereby forming a printed image with a film encapsulating at least a portion of the pigment on the vinyl medium. A method of forming a printed image of the latex polymer using the inkjet ink printing system is also provided.

The present disclosure includes naphthalocyanine dyes or fused naphthalocyanine dyes represented by one of the general structures I to XV; inkjet ink formulations including the naphthalocyanine dyes; and a detection system (300) including the dyes.
摘要:
A method for forming a functionalized latex polymer includes polymerizing a heterogeneous dispersion of water insoluble monomers in water, thereby forming a latex polymer. An at least partially water soluble halogenated non-ionic group is reacted with the latex polymer, whereby a halogen is displaced from the non-ionic group, thereby forming an at least partially water soluble non-ionic group that attaches to the latex polymer.

Polyphenylated phthalocyanine water-soluble dyes with near-infrared absorption comprise four isoindole units linked together in a large ring to form a phthalocyanine macrocycle, with either four anthracenyl groups or four naphthacenyl groups each linked to an isoindole, and a metal atom optionally complexed to the phthalocyanine macrocycle.
摘要:
Disclosed herein are pigment dispersions and inks formulated using the same; including at least one dispersed pigment, an aqueous carrier; and at least one block copolymer dispersant having Structure I and comprising a hydrophobic block (A) and a hydrophilic block (B); at least one block copolymer having Structure I and comprising a hydrophobic block (A) and a hydrophilic block (B);
摘要:
The present invention is drawn to polymer-encapsulated pigments and methods of making the same. The method includes providing an emulsion including water and a discontinuous coating phase having a copolymer dissolved in a monomer mix; providing a pigment dispersion including water, surfactant, and pigments dispersed therein; mixing the emulsion with the pigment dispersion under high shear conditions such that the coating phase is deposited on the pigments, thereby forming polymer and monomer coated pigments; and polymerizing the monomers at the surface of the polymer and monomer coated pigments to form polymer-encapsulated pigments dispersed in a fluid medium.

The present invention is drawn to pigment suspensions, methods of forming pigment suspensions, and ink sets. The pigment suspension can comprise a liquid vehicle and a polymer-encapsulated pigment suspended in the liquid vehicle. The polymer-encapsulated pigment can include a pigment core, a passivation layer of an alkoxy metal deposited on a surface of the pigment core, and a polymer encapsulation layer attached to or deposited on the passivation layer.
