Coatings of electrically conductive polythiophene salts, polythiophene.sup.+ /An.sup.-, and hydrolyzable silanes, wherein the polythiophene group contains positively charged and uncharged recurring units of the formula (I): ##STR1## where, n is an integer from 5 to 100, and

Scratch-resistant conductive coatings

Mixture of a polythiophene preparation which contains a polythiophene salt polythiophene.sup..sym. An.sup..crclbar. in which the polythiophene contains positively charged and uncharged recurring units of the formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another stand for hydrogen or a C.sub.1 -C.sub.4 alkyl group or together form an optionally substituted C.sub.1 -C.sub.4 alkylene radical, preferably a methylene radical optionally substituted with alkyl groups, an ethylene-1,2 radical optionally substituted with C.sub.1 -C.sub.12 alkyl groups or phenyl groups, a propylene-1,3 radical or a cyclohexylene-1,2 radical, and

Thermally and mechanically formable polymer film, characterised by a transparent antistatic coating of a mixture of 3,4-polyethylene dioxythiophene with a thermally or mechanically formable binder, its production and its use for packaging electronic components.

Flexible, deep-drawing, electrically conductive films

The invention relates to a process for the electrostatic lacquering of non-conductive surfaces. For this purpose, a layer of a conductive organic polymer from the class of the polypyrroles, polyanilines or polythiophenes is applied to the surface and this layer is then electrostatically lacquered.

Process for the electrostatic lacquering of non-conductive surfaces

This invention relates to new pure-colored iron oxide direct red pigments, to a process for their production and to their use for pigmenting lacquers, plastics, building materials and ceramics.

A process for preparing red ceramic molded bodies by rapid firing is disclosed, wherein low Si-content iron oxides are employed. The process produces molded bodies having improved colouristic properties.

Red ceramic moulded bodies as well as processes for their production

The invention relates to transparent iron oxide pigments having an average particle size, based on the longest needle axis, of less than 0.1 .mu.m, to processes for their production and to their use for pigmenting lacquers and plastics.
