ABSTRACT:
A non-aqueous pigment dispersion includes a quinacridone pigment, a polymeric dispersant, and a dispersion synergist in a non-aqueous dispersion medium wherein the dispersion synergist is a quinacridone derivative substituted on one of the two nitrogen atoms of the quinacridone basic chromophore structure by a group including at least one carboxyl group or a salt thereof. Also, a method for printing an ink-jet image with an ink including the non-aqueous pigment dispersion.
