    摘要： A process for increasing the solubility of carbon black in desired solvents is provided. The process comprises (a) forming a suspension of the carbon black in a non-reactive medium, such as an aromatic hydrocarbon, (b) adding a silylating agent, such as an organosilane, (c) removing the reaction product of the silating agent and the carbon black, and (d) forming a dispersion of the reaction product in a solvent for use as an ink-jet printing fluid.The increased dispersibility of the carbon black of the invention results in a more non-settling suspension of the carbon black "molecules" than otherwise obtained.

    摘要： A method and ink-jet ink composition are provided for reducing crystallization of Acid Yellow 23 anionic dye in ink-jet ink compositions printed on transparencies and glossy media, both film- and paper-based. The method comprises formulating the yellow ink-jet ink composition in accordance with at least one of the following three conditions: (a) a first condition, wherein the yellow ink-jet ink composition includes about 6 to 9 wt % ethylhydroxypropanediol, about 3 to 9 wt % 2-pyrrolidone, and about 3 to 9 wt % diethylene glycol; (b) a second condition, wherein the vehicle of the yellow ink-jet ink includes a buffer in amount sufficient to maintain the pH of the ink-jet ink within the range of about 5 to 7; and (c) a third condition, wherein the cation of the inorganic salt component of the ink-jet ink comprises calcium ions to the substantial exclusion of magnesium ions. While any or all of the foregoing conditions may be implemented to reduce crystallization in the yellow ink, a combination of the three is particularly efficacious. A narrower embodiment also incorporates two alternative techniques, namely reducing the dye load of the yellow ink to no more than about 3.5 wt % and increasing the thickness of the clear polymeric surface coating of the transparency or glossy media to at least about 12 .mu.m from its typical 10 .mu.m. The solution offered by the present method and ink-jet ink composition is easily and inexpensively implemented and does not sacrifice overall print quality.
