Abstract
An ink jet ink composition comprises a liquid vehicle and a dye modified to attach polymeric chains to the dye. The dye is water soluble and selected from the group consisting of Direct Dyes, Acid Dyes and Food Dyes. The polymer is selected from the group comprising polyethoxylated aromatic amines to enhance affinity of the dye to a cellulosic substrate. The modified dye in this ink jet composition has lower solubility and, therefore, can be used to formulate waterfast inks for ink jet printers.
