Abstract
Disclosed is an ink composition which comprises water, a colorant, and an additive selected from imidazolium formate, imidazolium phosphite, and mixtures thereof. Another embodiment of the invention includes a process which entails incorporating an ink composition of the present invention into an ink jet printing apparatus and causing droplets of the ink composition to be ejected in an imagewise pattern onto a substrate. In one 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. In another preferred embodiment, the ink is used in a printing process which employs microwave drying of the printed image.
