  1. 1
    A composition comprising:(a) an anionic amphiphilic ion;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  2. 5
    A composition comprising:(a) a cationic amphiphilic ion selected from ammonium ions formed by adding an acid to: a fatty amine, an ester of an aminoalcohol, an alkylamine, a polymer containing an amine functionality, aniline derivatives, a fatty alcohol ester of an amino acid, a polyamine N-alkylated with a dialkyl succinate ester, a heterocyclic amine, a guanidine derived from a fatty amine, a guanidine derived from an alkylamine, a guanidine derived from an arylamine, an amidine derived from a fatty amine, an amidine derived from a fatty acid, an amidine derived from an alkylamine, an amidine derived from an arylamine, an ester of an aminodiol, an ester of an aminotriol, a polyethyleneimine, a polyvinylimidazole, a homo- or co-polymer of vinylpyridine, a polyvinylimidazole, mixed polymers containing at least one amino-functional monomer, a fatty alcohol ester of aspartic acid, a fatty alcohol ester of glutamic acid, a pyridine derivative, an imidazole, an imidazoline, or a copolymer of dimethylaminoethyl methacrylate and methyl methacrylate;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  3. 6
    A composition comprising:(a) a cationic amphiphilic ion;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion, wherein said organic group comprises: (i) at least one aromatic group or at least one C 1 -C 12 alkyl group;and (ii) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group, wherein the at least one aromatic group of the organic group is directly attached to the carbon, and wherein the at least one C 1 -C 12 alkyl group of the organic group is directly attached to the carbon.
  4. 12
    The composition of claims 1, 5 or 6, wherein said carbon is carbon black, graphite, vitreous carbon, carbon fiber, finely divided carbon, activated charcoal, or mixtures thereof.
  5. 14
    The composition of claims 1 or 5, wherein said organic group comprises:(a) at least one aromatic group or at least one 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 at least one aromatic group of the organic group is directly attached to the carbon, and wherein the at least one C 1 -C 12 alkyl group of the organic group is directly attached to the carbon.
  6. 15
    The composition of claims 1, 5 or 6, wherein the organic group includes a carboxylate, a sulfonate or a quaternary ammonium ion.
  7. 20
    An aqueous ink composition comprising an aqueous vehicle and the composition of claims 1, 5 or 6.
  8. 21
    A coating composition comprising an aqueous vehicle and a composition comprising a) an amphiphilic ion and b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  9. 22
    A non-aqueous ink composition comprising a non-aqueous vehicle and a composition comprising:(a) an amphiphilic ion;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  10. 23
    A non-aqueous coating composition comprising a non-aqueous vehicle and a composition comprising:(a) an amphiphilic ion;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  11. 24
    A non-aqueous ink jet ink composition comprising a vehicle and a composition comprising:(a) an amphiphilic ion;and (b) a modified carbon product comprising carbon having attached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  12. 25
    An aqueous emulsion ink jet ink composition comprising a solvent, water and a composition comprising a) an amphiphilic ion and b) a modified carbon product comprising carbon having at- tached at least one organic group, wherein said at least one organic group has a charge opposite to said amphiphilic ion.
  13. 27
