Abstract: The present invention is directed to a pigment dispersion for an aqueous ink. The pigment is dispersed in a liquid by a dispersing agent wherein the dispersing agent comprises a styrene/maleic anhydride (SMA) copolymer, a reaction product of the SMA copolymer and an alcohol, or a combination of the SMA copolymer and the SMA copolymer/alcohol reaction product. The weight ratio of the pigment to the dispersing agent in the dispersion is from about 5:1 to about 9:1, and preferably from about 6:1 to about 8:1. The pigment comprises at least about 33 wt% of the total weight of the dispersion, preferably at least about 36 wt. % of the dispersion, and most preferably at least about 40 wt. % of the dispersion. An aqueous ink is prepared combining the pigment dispersion with an emulsion comprising a polymer stabilized in water. The pigment comprises at least about 10 wt.% of the total weight of the ink composition.
