ABSTRACT:
A set of ink-jet inks and method for reducing bleed are provided in which the ink-jet ink is formulated to comprise at least one dye-based ink-jet ink composition and at least one pigment-based ink-jet ink composition, wherein the dye-based ink-jet ink composition includes at least one cationic surfactant and wherein the pigment-based ink-jet ink composition includes at least one negatively-charged dispersant. Bleed control between the dye-based ink and the pigment-based ink is achieved by the formation of a stable interface formed by the interaction of the negatively-charged dispersant and both the cationic and counterion groups of the cationic surfactant.
