Water based permanent jet printing ink and method of use

A jet drop printing process utilizing a water base permanent jet printing ink comprising:

• a. ejecting at high speed from an orifice or orifices an ink composition comprising:
• a water or solvent soluble dyestuff present in the ink in the range of from about 1 percent to about 10 percent by weight, an alkylene glycol ether as a solvent for said dyestuff and having from 8 to 12 carbon atoms and present in the ink in the range from about 1 percent to about 6 percent by weight, an ethoxylated higher alcohol amine-amide phosphate as a bridging agent for the dyestuff and glycol ether rendering them soluble in water and present in the ink in the range from about 1 percent to about 6 percent by weight, a hydroxylated aliphatic amide as a humectant and present in the ink in the range from about 10 percent to about 40 percent by weight, and the balance water, so that said ink composition issuing from said orifice or orifices breaks into droplets;
• b. passing said stream of droplets through a charge ring to thereby differentially charge said droplets;
• c. selectively deflecting said differentially charged droplets and directing them toward a substrate positioned so as to receive at least a portion of said differentially charged droplets;
• and
• d. depositing at least a portion of said droplets in a pattern on said substrate, whereby a permanent, fast drying, smudge and light resistant printed pattern is formed on said substrate.
