摘要： An active energy ray-curable ink composition is disclosed which includes a colorant, a dispersant, a polymerizable compound and water. The dispersant includes a hydrophobic repeating unit including a residue obtained by removing one hydrogen atom from a compound selected from the group consisting of a benzene ring-containing compound, an aromatic hydrocarbon ring-condensed polycyclic compound, a heteromonocyclic compound and a hetero ring-condensed heteropolycyclic compound; a hydrophilic repeating unit including an ionic group; and a hydrophilic repeating unit including a nonionic group.
