The present invention relates to an aqueous ink containing a dispersant which is excellent in dispersibility of colorants such as pigments and which is composed of a crosslinked copolymer capable of maintaining a stable dispersion state for a long time in an aqueous medium. More specifically, an aqueous ink composed of a dispersant, a colorant and an aqueous medium composed of a crosslinkable copolymer comprising (A) a crosslinkable monomer, (B) an aromatic group-containing monomer and (C) an ionic monomer as essential components. It is about. |
