Abstract
Abstract A modified carbon product is described which comprises carbon having attached at least one organic group wherein the organic group comprises a) at least one aromatic group or a C 1 -C 12 alkyl group, and b) a group having the formula -AG-Sp-LG-Z, wherein AG is an activating group, Sp is a spacer group, LG is a leaving group, and Z is a counterion, and wherein the aromatic or the C 1 -C 12 alkyl group is directly attached to the carbon, and wherein the organic group is present in any amount. The present invention also relates to ink and coating compositions comprising these modified carbon products.
