Abstract:
The invention relates to an aqueous cyan inkjet ink composition for use in ink jet printers comprising an aqueous carrier, a self dispersed cyan pigment, a polymeric additive, a surfactant, and a specific cosolvent mixture comprising a C2-C8 terminal alkanediol, a cyclic amide compound and its derivative, a polyol/polyalkylene oxide condensate, and a trihydric alcohol. Preferably, the self dispersed cyan pigment is surface modified with bisphosphonate group. The cyan inkjet ink demonstrates excellent stability, superior chroma, good printhead maintenance characteristics and high heater reliability in permanent and semi permanent printheads.
