    摘要： Disclosed is a printing process which comprises applying in imagewise fashion to a substrate an ink composition which comprises an aqueous liquid vehicle, a colorant, and an ionic compound at least partially ionizable in the liquid vehicle, said ink composition having a conductivity of at least about 10 milliSiemens per centimeter, and subsequently exposing the substrate to microwave radiation, thereby drying the images on the substrate. A specific embodiment of the invention is directed to a thermal ink jet printing process which comprises (1) incorporating into a thermal ink jet printing apparatus an ink composition which comprises an aqueous liquid vehicle, a colorant, and an ionic compound at least partially ionizable in the liquid vehicle, said ink composition having a conductivity of at least about 10 milliSiemens per centimeter; (2) 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, thereby generating images on the substrate; and (3) exposing the substrate to microwave radiation, thereby drying the images on the substrate.

    摘要： A toner composition for use in a xerographic or electrostatographic imaging process. The toner composition includes a toner particle and an optional primary external surface additive and a friable external surface additive. The friable external surface additive may also be a material that is capable of functioning as a primary external surface additive. The friable external surface additive is generally larger than the primary surface additive and capable of having portions of the friable particle broken or abraded off during the imaging process. The particles that are abraded off the friable additive can replace the primary external additive particles that become embedded into toner particles during the development process. The friable additives contribute to reducing toner aging and provide a toner with satisfactory flow and triboelectric properties.
