Abstract
Provided are a method for producing an aqueous inkjet pigment dispersion, including producing a mixed liquid of water, a pigment, a pigment dispersing polymer, and rosin acid in an amount of from 3% by mass to 30% by mass relative to the total mass of the pigment, and reducing the amount of rosin acid included in the produced mixed liquid, to less than 3.0% by mass relative to the total mass of the pigment; an aqueous inkjet pigment dispersion; and an aqueous inkjet ink.
