<p>An aqueous ink is disclosed which contains a dispersing agent composed of a crosslinked copolymer which has excellent dispersibility of a coloring agent such as pigment and is capable of stably maintaining the dispersed state of a dispersoid in an aqueous medium for a long time. Specifically, the aqueous ink comprises a coloring agent, an aqueous medium, and a dispersing agent which is composed of a crosslinked polymer essentially containing (A) a crosslinkable monomer, (B) an aromatic group- containing monomer and (C) an ionic monomer.</p> |
