Abstract
A process for the preparation of light-colored, electrically conductive pigments based on substrates having an expansion of not more than 500 .mu.m, which pigments consist of one or more metals, metal oxides or materials containing metal oxide, silicon oxide or silicate materials and contain, if desired above one or more other metal oxide and/or silicon oxide layers, an outer layer based on halogen-doped tin oxide and/or titanium oxide.
Claims9
An light-colored, electrically conductive pigment comprising a substrate optionally coated with at least one metal oxide layer and thereon a conductive layer comprising halogen-doped tin oxide and/or halogen doped titanium oxide.
