摘要 |
Disclosed is a printing process which comprises applying in imagewise fashion to a substrate (3) an ink composition which comprises an aqueous liquid vehicle, a colorant, and a drying component selected from the group consisting of zwitterionic compounds, and subsequently exposing the substrate (3) to microwave radiation, thereby drying the images on the substrate (3). In a preferred embodiment, the invention is directed to a thermal ink jet printing process which comprises incorporating into a thermal ink jet printing apparatus an ink composition which comprises an aqueous liquid vehicle, a colorant, and a drying component selected from the group consisting of zwitterionic compounds; heating the ink in an imagewise pattern to cause bubbles to form therein, thereby causing droplets of the ink to be ejected in an imagewise pattern onto a substrate (3), thereby generating images on the substrate (3); and exposing the substrate (3) to microwave radiation in the drying apparatus 1, thereby drying the images on the substrate (3). <IMAGE> <IMAGE> |
