Abstract

Paints and printing inks are disclosed which contain carbon black as the pigment. The dispersion and storage stability of printing inks and paints may be improved by using carbon blacks containing silicon. The rheological behavior of the paints is improved by silicon-doping of the carbon blacks used. Paints having a reduced solvent content are consequently obtainable.
