Abstract
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.
