There is disclosed an aqueous ink jet ink composition comprising an aqueous vehicle and a carbon black product having attached at least one organic group. The organic group comprises a) at least one aromatic group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The organic group is directly attached to the carbon black by an aromatic group. Also disclosed is an aqueous ink jet ink composition comprising an aqueous vehicle and a carbon black product having attached at least one organic group. The organic group comprisies a) at least one C.sub.1 -C.sub.12 alkyl group group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The organic group is directly attached to the carbon black by an alkyl group. Ink jet recording methods applying an ink jet ink of the present invention are also described.
