Abstract
The present invention relates to an aqueous pigment dispersion that shows excellent dispersibility and storage stability, an inkjet ink that shows excellent jetability, water resistance, and adhesion, and a process for producing an aqueous pigment dispersion that shows excellent dispersibility and storage stability, as well as superior jetability, water resistance and adhesion. An aqueous pigment dispersion of the present invention comprises a dispersion formed by dispersing a monoalkyl maleate graft polymer of a maleic anhydride/α-olefin copolymer in water in the presence of a base, a pigment, and an aqueous medium.
