Abstract
The invention relates to a process for preparing electrically conductive pigments based on F - and/or PO -doped tin mixed oxides applied as an electrically conductive layer to a substrate, in which, first of all, SnO -coated substrates are prepared by precipitation and subsequent calcining and then, in further process steps, this SnO layer is converted into a tin mixed oxide layer doped with F and/or PO . The invention further relates to electrically conductive pigments prepared by the process of the invention, to the use of these pigments for pigmenting lacquers, printing inks, plastics systems or coatings, and to lacquers, printing inks, plastics systems or coatings pigmented with an electrically conductive pigment prepared by the process of the invention.
