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.
