Document Type and Number:
WIPO Patent Application WO/2015/151725
Kind Code:
A1
Abstract:
A method for producing an aqueous inkjet pigment dispersion, which comprises a mixed liquid production step for producing a mixed liquid of water, a pigment, a pigment dispersing polymer, and a rosin acid in an amount of from 3% by mass to 30% by mass (inclusive) relative to the total mass of the pigment, and a reduction step for reducing the amount of the rosin acid contained in the mixed liquid, which is obtained by the mixed liquid production step, 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.
