ABSTRACT:
An ink composition is disclosed including a liquid vehicle and an ionically charged organic pigment and a hydroxylated hydrocarbon humectant having at least two hydroxyl groups. The ionically charged pigment may be black, blue, brown, cyan, green, violet, magenta, red, orange, yellow, mixtures thereof, and the like. The ionically charged pigment, due to the nature of its surface charge, is readily-dispersed in the liquid vehicle of the ink composition without the addition of a surfactant or other dispersing aid or additive. In a preferred embodiment, the ionically charged pigment has sufficient ionizable groups to maintain the colloidal stability of the pigment in the ink composition.
Further disclosed is a method for generating printed images which include incorporating into a printing apparatus the ink compositions described above and generating an image onto a substrate.
