Abstract:
The present disclosure is drawn to ink compositions comprising from 1 wt % to 8 wt % of a colored pigment and a polymeric dispersant. The polymeric dispersant can be associated with the pigment and the weight ratio of the polymeric dispersant to pigment can be less than 0.33. The polymeric dispersant can have hydrophilic moieties and hydrophobic moieties and an acid number from about 40 to about 180. The ink composition can have an effective charge stabilization from about 0.3 to about 1.8 that is calculated based on a product of the acid number of the polymeric dispersant, the polymer dispersant to pigment weight ratio, and the pigment load in the ink.

Claim (Index 14):
An ink set, comprising at least two ink compositions of:\n a cyan ink, comprising:\n from 1 wt % to 8 wt % cyan pigment load, and \n a polymer dispersant associated with pigment and having hydrophilic moieties and hydrophobic moieties, wherein an acid number of the polymer dispersant is from about 40 to about 180, wherein a polymer dispersant to pigment weight ratio is less than 0.25, and wherein an effective charge stabilization of the cyan ink is from about 0.6 to about 1.5 calculated based on a product of the acid number of the polymer dispersant, the polymer dispersant to pigment weight ratio, and the cyan pigment load in the cyan ink composition; \n a magenta ink, comprising;\n from 1 wt % to 8 wt % magenta pigment load, and \n a polymer dispersant associated with pigment and having hydrophilic moieties and hydrophobic moieties, wherein an acid number of the polymer dispersant is less than 150, wherein a polymer dispersant to pigment weight ratio is less than 0.25, and wherein an effective charge stabilization of the magenta ink is from about 0.3 to about 1.2 calculated based on a product of the acid number of the polymer dispersant, the polymer dispersant to pigment weight ratio, and the magenta pigment load in the magenta ink composition; and \n a yellow ink, comprising:\n from 1 wt % to 8 wt % yellow pigment load, and \n a polymer dispersant associated with pigment and having hydrophilic moieties and hydrophobic moieties, wherein an acid number of the polymer dispersant is from about 40 to about 180, wherein a polymer dispersant to pigment weight ratio is less than 0.25, and wherein an effective charge stabilization of the yellow ink is from about 0.5 to about 1 calculated based on a product of the acid number of the polymer dispersant, the polymer dispersant to pigment weight ratio, and the yellow pigment load in the yellow ink composition.
