Zusammenfassung: | An ink composition which comprises an aqueous liquid vehicle, a colorant, and silica particles in an amount of from about 0.1 to about 5 percent by weight. The inks are particularly suited for ink jet printing processes, including thermal ink jet printing processes, and exhibit increased drop volume and increased drop velocity when employed in ink jet processes. |
