The invention relates to an oxidatively aftertreated carbon black. It is characterised in that its content of volatile constituents is more than 10 wt.%, based on its total weight, and the ratio of its CTAB surface area to the iodine number is greater than 2 m2/mg. The carbon black according to the invention is used preferably as pigment carbon black for the production of water-based paints, printing inks and as inks for mechanical and manual recording and drawing instruments. The combination of properties imparts to the carbon black an excellent dispersibility in water-based binder systems. The paints, printing inks and printer inks produced from it have an outstanding stability in storage.
