Abstract
Aqueous carbon black dispersions contain carbon black and cationic and non-ionic surfactants in addition to water. The dispersions are produced by dispersing the carbon black and the other components in water with bead mills, ultrasonic mills or an Ultra Turrax mixer. The dispersions can be used to produce inks, lacquers and printing inks.
