ABSTRACT:
Disclosed is a thermal ink jet printing process which comprises (a) incorporating into a thermal ink jet printer an ink composition comprising water, a dye, and pigment particles having an average particle diameter of from about 0.001 micron to about 10 microns, said pigment particles being present in the ink in an amount of less than 0.1 percent by weight; and (b) causing droplets of the ink to be ejected in an imagewise pattern onto a recording medium by selectively heating the ink in the printer in an imagewise pattern, thereby generating images on the recording medium. The disclosed ink is capable of producing a large drop mass, high ink velocity, good directionality, and high quality images on plain papers with excellent long-term jetting stability.
