摘要:
In accordance with embodiments of the present invention, an ink-jet ink can comprise a dye and a liquid vehicle carrying the dye. The liquid vehicle can include a sulfonated aromatic compound present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness of said ink-jet ink.
摘要:
Anti-bronzing compounds are added to inkjet inks to prevent bronzing of the inks when printed on specialty quick-dry inkjet photographic media. These compounds inhibit bronzing by the proper buffering of the dyes relative to the media of interest.
摘要:
A puddling additive comprising a nonionic, polar group and a C6-C30 hydrocarbon tail for use in reducing puddling in an inkjet ink. The inkjet ink also comprises a dye and an ink vehicle. A method of reducing puddling in an inkjet ink is also disclosed. The method comprises adding a puddling additive to the inkjet ink, wherein the puddling additive comprises a nonionic, polar group and a C6-C30 hydrocarbon tail.
摘要:
A puddling additive comprising an anionic, polar group and a C6-C30 hydrocarbon tail for use in reducing puddling in an inkjet ink. The anionic, polar group is a carboxylate or phosphate group and the C6-C30 hydrocarbon tail is a saturated or unsaturated C6-C30 hydrocarbon chain. An inkjet ink comprises a puddling additive, a dye, and an ink vehicle. A method of reducing puddling in an inkjet ink is also disclosed. The method comprises adding the puddling additive to the inkjet ink.
摘要:
The inks provide excellent ink-jet prints having excellent imaging onto the media with sharp, smooth edge text print and overall print quality improvements. The aqueous inks each comprise an anionic colorant (CMYK), a short chain alcohol or diol and a cationic surfactant.
摘要:
A print medium having increased resistance to gasfade. An inhibitor comprising a sulfur-containing polymer is incorporated into the print medium. The sulfur-containing polymer is poly(1,4-phenylene sulfide) or poly(1,3-phenylene sulfide). The inhibitor is present in at least a surface of the print medium and may be present in the print medium in a concentration from approximately 0.25% by weight per cm2 of the print medium to approximately 30% by weight per cm2 of the print medium. A method of forming the print medium is disclosed as is a method of producing a printed image having increased resistance to gasfade.
摘要:
Cationic underprinting fluids, which together with pigment-based ink compositions achieve enhanced durability, chroma, optical density and print quality in inkjet printed images.
摘要:
An inkjet ink composition having good stability which is an aqueous dispersion and/or solution of large particles of water soluble pigments derived from laked dyes, the water solubilizing groups on the surface of the laked dyes being exposed by removing surface counter-cations with chelating agents.
