Abstract
Abstract A modified carbon product is described which comprises carbon having attached at least one organic group. The organic group comprises a) at least one aromatic group or a C 1 -C 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. The aromatic group or the C 1 -C 12 alkyl group of the organic group is directly attached to the carbon and the organic group is present at a level of from about 0.10 to about 2.7 micromoles/m 2 of the carbon used based on CTAB or t-area of the carbon or in an amount such that the modified carbon product has a residue value of more than about 5 wt %. Also described are aqueous and non-aqueous inks and coatings containing the modified carbon product. A method to increase the flow of an ink, as measured by glass plate flow, by incorporating the modified carbon product as part of the ink is also disclosed. Lastly, non-aqueous ink and coating formulations are described which contain an appropriate solvent and a modified carbon product comprising carbon having attached at least one organic group, wherein the organic group comprises a) at least one aromatic group or C 1 -C 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, wherein the organic group is present in any amount.
