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