摘要： An ink composition which comprises an aqueous liquid vehicle, a colorant, and silica particles in an amount of from about 0.1 to about 5 percent by weight. The inks are particularly suited for ink jet printing processes, including thermal ink jet printing processes, and exhibit increased drop volume and increased drop velocity when employed in ink jet printing processes.

摘要： Disclosed is a process for preparing an aqueous ink composition which comprises adjusting the pH of the ink with phosphorous acid or phosphite salts. Also disclosed are ink compositions prepared by this process. In certain preferred embodiments, the ink compositions can also contain betaine, sulfolane, dimethyl sulfoxide, or N,N'-bis(3-aminopropyl)-1,2-ethylenediamine, as well as mixtures thereof. In other preferred embodiments, the ink composition comprises an organic component selected from the group consisting of sulfolane, dimethyl sulfoxide, and mixtures thereof, and anions selected from the group consisting of phosphite, hypophosphite, phosphate, polyphosphate, sulfate, hexafluorophosphate, glycolate, acetate, ethylenediaminetetraacetate, formate, borate, sulfite, sulfamate, and mixtures thereof.
