A pearlescent pigment based on a metal oxide-coated, platelet-shaped substrate and a top layer on the metal oxide layer, where the top layer comprises silicon dioxide, at least one further metal hydroxide or metal oxide hydrate and at least one organic coupling reagent. The further metal hydroxides or metal oxide hydrates are hydroxides or oxide hydrates of cerium, aluminum or zirconium, or mixtures thereof. The coupling reagents employed are organofunctional silanes, zirconium aluminates or metal acid esters.

Pearlescent pigment for water-borne surface-coating systems

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.

Process for preparing electrically conductive pigments

The present invention relates to a pearl luster pigment on the basis of a platelet-shaped substrate coated with metal oxides and a top layer which is located on the metal oxide layer and can possess a multilayer structure, comprising a first layer, containing a hydroxide or oxide hydrate of the elements aluminum or silicon, a second layer, containing at least one hydroxide or oxide hydrate of the elements aluminum, silicon, cerium or zirconium, with the exception of the hydroxide or oxide hydrate which forms the first layer, and a third layer, containing at least one organic hydrophobic coupling agent. The present invention also relates to a preparation process and the use of pigments in paints, inks, plastics, coatings and cosmetics.

After coating of pearl luster pigments with hydrophobic coupling reagents

The invention relates to a pearl luster pigment which may possess a first, inner layer, consisting of a platelet-shaped substrate, a second layer, comprising one or more metal oxides, the first and second layers forming a calcined base pigment, a third layer, comprising the corresponding uncalcined oxide, hydroxide or oxide hydrate of the oxide of the second layer, a fourth layer, comprising oxides, hydroxides and/or oxide hydrates of silicon or aluminum, a fifth layer, comprising oxides, hydroxides and/or oxide hydrates of silicon, aluminum, zirconium and/or cerium, this layer differing from the fourth layer, and a sixth layer, comprising one or more organofunctional coupling reagents. The present invention relates to also a preparation process, and the use of the pigments in paints, inks, plastics, coatings and cosmetics.

Stabilization of pearl luster pigments

The invention relates to novel manganese dioxide electrodes containing modified, electrochemically active manganese dioxide, a method for their production and their use in primary electrochemical cells. The manganese dioxide electrode contains coated or uncoated inorganic particles, in which the carrier particles consist of a material chosen from the group: mica, SiO2, Al2O3, ZrO2 and ZnO.

Modified electrode material and its use

The invention relates to novel manganese dioxide electrodes comprising modified, electrochemically active manganese dioxide, to a method for fabricating these novel manganese dioxide electrodes and to the use of these in rechargeable cells.

Manganese dioxide electrodes, process for producing the same and their use

A pale electrically conductive pigment consisting of a substrate and an electrically conductive layer formed of phosphorus- and/or fluorine-doped tin oxide. There may be an interlayer disposed between the substrate and the conductive layer.
