ABSTRACT:
An ink composition for an ink jet printer. The ink composition contains an oligomeric dispersant, a pigment and a solvent. The oligomeric dispersant simultaneously has a hydrophilic group capable of interacting with water soluble solvent and an anchoring group capable of interacting with the pigment. The ink composition provides good printing properties, water fastness, light fastness and storage stability, by using less amount of dispersant.
