    • The invention relates to a process for preparing electrically conductive pigments based on F−- and/or PO43−-doped tin mixed oxides applied as an electrically conductive layer to a substrate, in which, first of all, SnO2-coated substrates are prepared by precipitation and subsequent calcining and then, in further process steps, this SnO2 layer is converted into a tin mixed oxide layer doped with F− and/or PO43−. 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.
    • 本发明涉及一种制备基于作为导电层施加到衬底上的掺杂有PO 3 - 和/或PO 4 3-的锡混合氧化物的导电颜料的方法,其中首先将SnO 2 - 通过沉淀和随后的煅烧制备涂覆的基材,然后在进一步的工艺步骤中,将该SnO 2层转化为掺杂有F和/或PO 4 3-的锡混合氧化物层。 本发明还涉及通过本发明的方法制备的导电颜料,用于这些颜料用于着色漆,印刷油墨,塑料体系或涂料以及漆,印刷油墨,塑料体系或用导电颜料着色的涂料 通过本发明的方法制备的颜料。
