ABSTRACT:
The invention relates to an aqueous ink composition for use in ink jet printers comprising an aqueous carrier, an insoluble pigment, a polymeric dispersant, and a specific cosolvent mixture comprising 1,3-propanediol or 1,4-butanediol with a second component selected from polyethylene glycol-type materials and polyol/alkylene oxide condensates. The ink compositions demonstrate excellent stability, good maintenance characteristics for the printers in which they are used, and excellent optical density and print characteristics.
