ABSTRACT:
An ink composition and a method for preparing the ink composition are disclosed. The ink composition provides stability, bleed resistance and lightfastness without requiring the use of a cosolvent. The composition is based on a polymeric dispersant which is compatible with the hydrophobic surfaces of many pigments and which forms a stable dispersion of pigment in an aqueous environment. The ink composition is useful for organic and inorganic pigments.
