ABSTRACT:
Disclosed herein are aqueous ink compositions containing a specific humectant or a mixture of such humectants. The use of such humectants in aqueous ink compositions greatly mitigates the problems arising with the crusting and clogging of orifice plates in thermal ink jet printers associated with aqueous ink compositions not employing a humectant. Additionally, the use of such humectants in aqueous ink compositions greatly mitigates the kogation problems arising in thermal ink-jet printers from humectants heretofore employed in aqueous ink compositions.
