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 1):
An ink composition, comprising:\n from 1 wt % to 8 wt % pigment load, and a polymer dispersant associated with pigment, the polymer dispersant having hydrophilic moieties and hydrophobic moieties and an acid number from about 40 to about 180, wherein the polymer dispersant to pigment weight ratio is less than 0.33, and wherein an effective charge stabilization of the ink composition is from about 0.3 to about 1.8 calculated based on a product of the acid number of the polymer dispersant, the polymer dispersant to pigment weight ratio, and the pigment load in the ink composition.
