    摘要: An aqueous ink-jet ink composition for MICR applications is provided comprising a metal oxide pre-dispersion combined with an aqueous ink-jet ink composition, wherein the metal oxide pre-dispersion contains metal oxide pigment or particles of a very small particle size, at least one surfactant to aid in the aid in the dispersion of the metal oxide particles. Particularly, the surfactant component is a combination of an anionic surfactant and an anionic-nonionic surfactant, or may be a combination of other types of surfactants.
