摘要： An inkjet ink having sufficient water resistance on a recording sheet but having excellent re-solubility in an ink in a head portion and excellent ejection stability through a nozzle, the inkject ink comprising an aqueous liquid, a pigment and a water-soluble resin, the water-soluble resin being a terpolymer obtained from acrylic acid, styrene and .alpha.-methyl styrene and having a weight average molecular weight of 2,000 to 8,000 and an acid value of 90 to 130, and a process for the production of the inkjet ink, which comprises preparing a concentrated aqueous dispersion of a pigment and a terpolymer obtained from acrylic acid, styrene and .alpha.-methylstyrene, adding water and an additive to the concentrated dispersion to dilute the concentrated dispersion and maintaining the diluted dispersion at a temperature between 60.degree. C. and 80.degree. C. for 5 to 48 hours.
