The invention relates to a non-aqueous coating composition and to a non-aqueous ink composition, both containing modified carbon product, as well as to a method of improving the optical properties of the compositions containing said product. A non-aqueous coating or ink composition having incorporated a modified carbon product comprising carbon, to which a substituted or unsubstituted aromatic group is attached directly to the carbon is described. Also described is a modified carbon product comprising carbon and an attached organic group having: a) an aromatic group and b) at least one group having the formula SO2NR2 or SO2NR(COR), wherein R is independently hydrogen, a C1-C20 substituted or unsubstituted alkyl, a C3-C20 substituted or unsubstituted alkenyl, (C2-C4alkyleneoxy)xR' or a substituted or unsubstituted aryl; R' is hydrogen, a C1-C20 substituted or unsubstituted alkyl, a C3-C20 substituted or unsubstituted alkenyl, a C1-C20 substituted or unsubstituted alkanoyl or aroyl, and x ranges from 1 to 40. |
