ABSTRACT:
Inks used in ink-jet printing comprise a vehicle and a dye. The vehicle consists essentially of about 5 to 10 wt % of a glycol and/or glycol ether and the balance water. The dye is typically an anionic dye, associated with undesirable cations such as sodium or potassium cations. Several properties of such inks are improved by replacing substantially all of said cations on the anionic dye with lithium cations and removing such cations, preferably to leave a maximum concentration of such cations of less than about 500 ppm, and most preferably less than about 350 ppm.
