The application relates to electrically conductive pigmentary platelets, where substrate platelets are coated with an electrically conductive layer, characterised in that the substrate platelets are in the form of metal oxide platelets or a platelet material which is coated with one or more metal oxides, and in that an optionally hydrated silicon dioxide layer or a layer of another insoluble silicate is arranged between the metal oxide layer and the electrically conductive layer.
