Abstract
The invention relates to an aqueous yellow inkjet ink composition for use in ink jet printers comprising an aqueous carrier, a yellow pigment, a polymeric dispersant, a surfactant, and a specific cosolvent mixture comprising a C-Cterminal alkanediol or a mixture thereof, a polyol/polyalkylene oxide condensate, a cyclic amide and its derivative, and a trihydric alcohol. The yellow inkjet ink demonstrates excellent stability, good maintenance characteristics and high heater reliability in permanent and semi permanent printheads. The ink also reduced post print paper curl without sacrificing print quality.
