    摘要: Inkjet ink compositions and methods for increasing inkjet ink particle stability are disclosed herein. In an embodiment, a latex polymer-containing inkjet ink composition comprises a secondary alcohol ethoxylate and a fluoro-surfactant at a concentration ratio effective to increase particle stability of the inkjet ink composition when the pigment particles are substantially electrostatically dispersed. In another embodiment, an inkjet ink composition comprises a latex dispersion having a conductivity of no more than about 1.5 mS/cm.

    摘要: A method of selecting a dye for use with a spreading vehicle can comprise the steps of evaluating a first dye having polar atoms and a second dye having polar atoms to determine a first polarity index and a second polarity index, respectively; and selecting the first dye or the second dye for inclusion in the spreading vehicle based upon a comparison of the first polarity index and the second polarity index. Further, a method of evaluating a dye and formulating an ink-jet ink can comprise the steps of providing a spreading ink-jet ink vehicle; selecting a dye to be evaluated for inclusion in the spreading ink-jet ink vehicle; determining the ratio of polar atoms to carbon atoms within the dye; selecting a desired polarity index ratio range; and admixing the dye with the spreading ink-jet ink vehicle if the ratio is within the desired polarity index ratio range. Additionally, an ink-jet ink composition exhibiting reduced orifice plate puddling can comprise an ink-jet ink vehicle containing 7% to 15% by weight of a 1,2-hexanediol solvent in the absence of added surfactant; and an effective amount of a dye having a normalized polarity index from about 7 to 12.
