摘要: An aqueous ink jet ink composition having improved dispersion stability comprises an aqueous carrier medium, a pigment having a pH value below 7.0, and an AB block polymer consisting of an A block comprising a hydrophobic polymer having at least one basic amine functional groups, and a B block comprising a hydrophilic polymer selected from the group consisting of nonionic polymers and polymers containing acidic functional groups.
