    摘要： This invention pertains to an aqueous based dispersion of Pigment Yellow 74 which uses a certain class of polymeric dispersants which dispersant is particularly effective at dispersing the pigment and preventing pigment particle growth on storage. The classes of polymeric dispersants are based on random copolymers of an ionic momomer and a hydrophobic monomer chosen from benzyl(meth)acrylate or alkyl(meth)acrylate where the alkyl group has four to ten carbon atoms and (meth)acrylic acid. The invention also pertains to an inkjet ink comprising this Pigment Yellow 74 dispersion.

    摘要： The present disclosure provides a black ink-jet ink, having a pH greater than 7, comprising a first aqueous vehicle, a carbon black pigment, and an amphoteric polymeric dispersant, wherein the amphoteric polymeric dispersant is a block copolymer comprising an A block and a B block, wherein the A block is a segment consisting essentially of an amine monomer; and the B block is a segment comprising an acidic monomer and at least one hydrophobic monomer; wherein the dispersant is neutralized, and with the proviso that the acid number is greater that the amine number, and the B block does not contain an amine monomer. The disclosure further pertains to an ink set comprising this black ink and at least a second ink which contains a reactive species with appropriate cationic agent, salt, or pH capable of destabilizing the carbon black dispersion. Still further, the disclosure pertains to a method of printing wherein the black ink and second ink are printed in an adjacent relationship, thereby minimizing penetration, feathering and/or bleed of the black pigment and improving print quality.

    摘要： The present disclosure provides a ink-jet ink, having a pH greater than 7, comprising a first aqueous vehicle, a colorant, more typically a carbon black pigment, and an amphoteric polymeric dispersant, wherein the amphoteric polymeric dispersant is a block copolymer comprising an A block and a B block, wherein the A block is a segment consisting essentially of an amine monomer; and the B block is a segment comprising an acidic monomer and at least one hydrophobic monomer; wherein the dispersant is neutralized, and the B block is free of an amine monomer. The disclosure further pertains to an ink set comprising this ink jet ink and at least a second ink which contains a reactive species with appropriate cationic agent, salt, or pH modifying agent capable of destabilizing the colorant containing dispersion of the first ink. Still further, the disclosure pertains to a method of printing wherein the first ink and second ink of the ink set are printed in an adjacent relationship, thereby minimizing penetration, feathering and/or bleed of the colorant and improving print quality.
