摘要： An aqueous ink comprising a polymer having hydroxyl groups and a pigment, which can provide images excellent in scratch resistance and highlighter resistance and can inhibit the seeping out phenomenon of the polymer and the deterioration of ejection characteristics even when it is stored for a long period of time. The aqueous ink comprises a polymer having hydroxyl groups, a pigment and a water-soluble organic solvent, wherein the water-soluble organic solvent comprises a poor medium for a polymer that is not adsorbed on the pigment (out of the polymer having hydroxyl groups), and wherein when the segment constituting the polymer that is not adsorbed on the pigment (out of the polymer having hydroxyl groups) is comprised of a segment A having hydroxyl groups and a segment B having no hydroxyl group, at least one of the poor medium is a good medium for either one of the segment A and the Segment B.
