Abstract: An aqueous dispersion of carbon black contains 1-45 wt.% carbon black and 1-40 wt.% cationic surfactant. An Independent claim is included for a process for the production of the dispersion by dispersing the carbon black and wetting agent in water, optionally by means of a bull mill, ultrasonic device or ultra-Turrax.

Abstract: A pigment preparation (I) contains a pigment and/or carbon black and a polymer and/or non-ionic surfactant, preferably cross-linked polyoxyethylene acrylic acid, fatty alcohol polyglycol ether, polyvinyl pyrrolidone, alcohol alkoxylate, alkylphenol glycol ether, lignin sulfonate and/or naphthalenesulfonic acid derivatives. An Independent claim is also included for a process for the preparation of the pigment preparation (I) by freeze drying of the aqueous preparation and optionally communication.

Abstract: Aqueous carbon black dispersions, wherein the carbon black dispersions contain no wetting agent and contain at least one ozone-oxidised carbon black. Said dispersions are produced by dispersing ozone-oxidised carbon black and the other constituents in water. Said dispersions may be used for the production of inks, printing inks and water-based lacquer systems.
