Abstract
A process for increasing the solubility of carbon black in desired solvents is provided. The process comprises (a) forming a suspension of the carbon black in a non-reactive medium, such as an aromatic hydrocarbon, (b) adding a silylating agent, such as an organosilane, (c) removing the reaction product of the silating agent and the carbon black, and (d) forming a dispersion of the reaction product in a solvent for use as an ink-jet printing fluid. The increased dispersibility of the carbon black of the invention results in a more non-settling suspension of the carbon black 'molecules' than otherwise obtained.
