Abstract

Aqueous carbon black dispersions contain carbon black and cationic surfactants in addition to water. The aqueous carbon black dispersions are produced by dispersing the carbon black and 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.
