ABSTRACT:
An improved jet printing ink for use in jet drop printers and copiers is provided. The composition comprises an aqueous solution of a water soluble or solvent soluble dye, an organic chemical solvent comprising a glycol ether having 8 to 12 carbon atoms, a bridging agent for solubilizing the solvent and dye in solution comprising an ethoxylated higher alcohol amine-amide, a humectant, and a defoaming agent.
The ink runs well in a multi-jet printer and will not dry out or clog printing head orifices even if left in the printing head for an extended period. The ink is fast drying on paper once printed and is smudge and light resistant.
