Liquid vehicle systems for improving latex ink-jet ink frequency response

摘要

A latex particulate-containing ink-jet ink can comprise an aqueous liquid vehicle including 0.5 wt % to 10 wt % of an additive selected from the group consisting of a C₄ to C₈ 1,2-alkanediol, a high HLB nonionic surfactant having at least 15 ethylene oxide units, and mixtures thereof. The ink-jet ink can further include latex particulates dispersed in the liquid vehicle, and can also include a colorant solvated or dispersed in the liquid vehicle. In accordance with embodiments of the present invention, the ink-jet ink can be configured to have a stable mean drop velocity range that does not vary more than 40% when fired from thermal ink-jet architecture.
