    摘要: Water-fastness in aqueous ink-jet inks containing water-soluble dyes is achieved by using a specific ionic species having a charge opposite to that on the dye molecule. Anionic dyes typically contain sulfonate (or carboxylate) anionic groups. Using at least one specific ionic species of opposite charge, specifically, phosphonium salts, causes the colorant components to “crash” or precipitate out of the water-based ink onto the print medium due to the formation of a suitable charge complex between the ionic parts of the dye and the opposite charge of the counter-ion species. Other positively charged salts, such as quaternary ammonium salts, carbonium salts, iodonium salts, sulfonium salts, and pyrillium salts may be used to improve aqueous dispersion stability and thus printability. Such additional cationic salt partially replaces the phosphonium salt(s). Alternatively, certain surfactants, such as aromatic ethoxylates, polyethylene oxide ethers, or polypropylene oxide ethers may be used to improve print quality.

    摘要: Color ink sets for use in printer systems are provided and formulated to provide improved plain paper and special media performance while maintaining good printing characteristics. The inks and ink sets of the present invention exhibit excellent color performance and lightfastness across a range of media, robust K/Y bleed resistance on plain paper at fast print speeds, as well as excellent printability and reliability. A specific dye set for formulating yellow, magenta, and cyan inks comprises a mixture of acid yellow 23 (AY23) and direct yellow 132 (DY132), a mixture of a cyan dye compound having the formula: —(SO3H)2.7 CuPc—(SO2NH2)0.5 —(SO2NH(C2H4OH)0.8 wherein Pc represents a phthalocyanine nucleus and acid blue 9; and a magenta dye compound having formula: wherein Q is a cation.

    摘要: Various ink formulations utilizing particular magenta dyes have excellent printing characteristics with high chroma and good lightfastness on plain paper and minimal humid bleed and hue shift on special media. The magenta humid bleed shift has been greatly reduced, especially on photo glossy materials. A single dye may be used in comparison to blended dyes which have been used in the past.
