Summary: | An ink composition that includes a self-dispersing pigment that has about 0.02 to about 1.0 mMoles of S and about 0.2 to about 2.0 mMoles of active hydrogen per gram of pigment, water, and an organic solvent. A method of making an ink composition that includes sulfonating a pigment, subsequently oxidizing the pigment to produce a modified pigment, and incorporating the modified pigment into an ink. |
