Abstract: An ink jet ink composition comprises a liquid vehicle, a pigment, a pH adjusting component, and a chemical with a plurality of electron donating groups. The chemical with a plurality of electron donating groups comprises a chemical with at least three electron donating groups, wherein the at least three electron donating groups are situated in close proximity to provide high dried film resistivity. With the present invention, significant improvement in dried film resistivity of carbon pigment ink jet inks is achieved, sufficient to eliminate charge lead to charge lead shorts and improve machine runnability and can, therefore, be used in ink jet printers.

Abstract: An ink jet ink composition comprises a security component, a liquid vehicle, a dye, and an N-hydroxyalkyl imine substituted at about 80% of the available nitrogens. The security component in this ink jet composition causes the ink to maintain color when subjected to bleach to prevent alteration of a printed document, and can be used in ink jet printers.

Abstract: An ink jet ink composition comprises a liquid vehicle, a dye, and an N-hydroxyalkyl branched polyethyleneimine polymer or an N-hydroxyalkyl diphenylguanidine substituted at about 80% of the available nitrogens. The dye in this ink jet composition decreases the solubility of the ink and, therefore, can be used to formulate waterfast inks for ink jet printers.

Abstract: There is described an aqueous ink comprising at least about 40 wt % of a humectant, and a dye or dye admixture compatible with such large amounts of humectant, that is, an admixture which does not precipitate because of such large amounts of humectant.
