    摘要： Bleed between two adjacent inks on a printing medium may be reduced by selecting inks having the same ionic character, at least one ink containing an aqueous carrier medium and a pigment dispersion wherein the dispersant is a quaternized amine containing polymeric dispersant, and wherein the second ink contains an aqueous carrier medium, a colorant and optionally a polymer, wherein the colorant or the polymer has a sulfonate or phosphonate group. A process for alleviating bleed in printed elements comprising applying the first and second inks to a substrate in contact with each another is also described.

    摘要： A graft polymer having (a) a hydrophilic backbone prepared from unneutralized acid containing monomers wherein the acid has a pKa of at least 3, and wherein the backbone is completely soluble in water and insoluble in non-polar organic solvents; and (b) at least one discrete hydrophobic side chain, wherein 20 to 100% of the side chains are prepared from non-polar aliphatic or aromatic monomers having a chain length of at least 4 carbon atoms; wherein the side chains are attached to the backbone at a single terminal point and wherein the at least one discrete hydrophobic side chain has a weight average molecular weight of 1000 to 30,000. These graft polymers are useful as dispersants in aqueous solutions, particularly in ink jet inks.

    摘要： Ink-receiving print media products having multiple capabilities including (A) minimal drying time; (B) improved smear-fastness; (C) a high level of water-fastness; (D) the ability to generate high-definition images; and (E) excellent ink compatibility. The media products have at least one ink-receiving layer on a substrate (e.g. paper pre-coated with one or more binders and/or pigments). The ink-receiving layer includes a pigment (boehmite, pseudo-boehmite, or mixtures thereof) optimally combined with a special binder blend [polyvinyl alcohol, a poly(vinyl acetate-ethylene) copolymer, and a poly(vinyl pyrrolidone-vinyl acetate) copolymer]. Also included is a special dye fixative (namely, a cationic emulsion polymer) which provides enhanced water-fastness. This fixative is of a particular type (a quaternary amine) that also allows high pigment levels to be employed (at least about 65% by weight) which further promotes the foregoing benefits.
