Non-aqueous inks and coatings containing modified carbon products

A non-aqueous ink composition comprising a non-aqueous solvent and a modified carbon product comprising carbon having attached a substituted or unsubstituted aromatic group.

A modified carbon product comprising a carbon having an attached organic group having a) an aromatic group and b) at least one group of the formula SO.sub.2 NR.sub.2 or SO.sub.2 NR(COR) wherein R is independently hydrogen, a C.sub.1 -C.sub.20 substituted or unsubstituted alkyl, a C.sub.3 -C.sub.20 substituted or unsubstituted alkenyl, (C.sub.2 -C.sub.4 alkyleneoxy).sub.x R' or a substituted or unsubstituted aryl;

• R' is hydrogen, a C.sub.1 -C.sub.20 substituted or unsubstituted alkyl, a C.sub.3 -C.sub.20 substituted or unsubstituted alkenyl, C.sub.1 -C.sub.20 substituted or unsubstituted alkanoyl or substituted or unsubstituted aroyl;
• and x is from 1 to 40.

A method for improving optical properties of a non-aqueous coating composition, comprising the step of:

• incorporating into the non-aqueous coating composition a modified carbon product comprising carbon having attached a substituted or unsubstituted aromatic group.
