Polymer colloid-containing ink-jet inks for printing on non-porous substrates

摘要

The present invention is drawn toward an ink-jet ink, comprising an aqueous liquid vehicle having acid-functionalized polymer colloid particulates and polymer-attached pigment colorants dispersed in the liquid vehicle. The liquid vehicle can include at least one volatile co-solvent, each volatile co-solvent present having a boiling point at or below about 285 DEG C. The total amount of volatile co-solvent present in the ink-jet ink can be from 5 wt% to 50 wt%. These ink-jet inks can be printed on traditional as well as non-porous substrates. Optionally, heat can be applied to an image printed with the ink-jet ink to drive off at least a portion of the volatile co-solvent(s).
