Ink compositions.

摘要

Disclosed is an ink composition which comprises an aqueous liquid vehicle, a colorant, and a phosphate ester. The inks described are particularly suitable for ink jet printing processes, especially thermal ink jet printing processes. The inks exhibit low viscosities and rapid drying times, particularly on plain paper. Also disclosed is a process for generating images on a substrate, which process comprise incorporating such an ink into an ink jet printing apparatus and causing droplets of the ink composition to be ejected in an imagewise pattern onto the substrate.
