ABSTRACT:
Inks for printing on plain papers are provided for thermal ink-jet printers. The inks comprise a vehicle comprising about 5 to 20 wt % of a glycol or glycol ether and the balance water, about 1 to 6% of a dye, and about 0.1 to 1% of an alginate. The alginate increases the viscosity to increase the frequency of operation. Unexpectedly, good print quality associated with lower frequency of operation is retained at the higher frequency of operation.
