ABSTRACT:
The present invention relates to an aqueous ink, particularly an aqueous ink suitable for ink jet recording. The ink is an aqueous ink comprising a modified pigment having organic groups chemically attached to the surface of a particle of the pigment and an aqueous medium which is a dispersant of the pigment, wherein the above-described organic group includes a reaction product of a functional group chemically attached to the surface of the pigment directly or via another atomic group with a copolymer of an ionic monomer and a hydrophobic monomer.
