Disclosed is a process which comprises incorporating into an ink jet printing apparatus an ink composition which comprises water, a colorant, and a comb copolymer, and causing droplets of the ink to be ejected in an imagewise pattern onto a substrate. In a particularly preferred embodiment, the printing apparatus employs a thermal ink jet process wherein the ink in the nozzles is selectively heated in an imagewise pattern, thereby causing droplets of the ink to be ejected in imagewise pattern.
