The aim of the invention is to create a composition for coating electric conductors which is significantly more resistant to partial discharges than prior art compositions while the produced insulating layer is highly extensible. Said aim is achieved by a composition comprising 1 to 50 percent by weight of microparticles that have a specifically adjusted electronic defect structure in the crystal lattice, resulting in greater polarizability of the valence electrons, and an organic and/or organic-inorganic matrix. The microparticles that have a specifically adjusted electronic defect structure are composed of oxides, sulfides, selenides, tellurides of the elements which are part of the series encompassing silicon, zinc, aluminum, tin, boron, germanium, gallium, lead, the transition metals, lanthanides, and actinides, particularly from the series encompassing silicon, titanium, zinc, yttrium, cerium, vanadium, hafnium, zirconium, nickel, and/or tantalum, in such a way that the basic lattice is provided with vacant lattice positions by doping 4 the basic lattice with adequate low-valent or higher-valent elements, said vacant lattice positions increasing the electronic polarizability of the microparticles by means of defect chemistry (the defect structure).

Coating composition for electrical conductors and method of producing such a composition

The invention relates to a method for transferring surface structures such as interference layers, holograms, and other highly refractive optical microstructures to substrates. The aim of the invention is to devise a method which is used for transferring surface structures such as interference layers, holograms, and other highly refractive optical microstructures to substrates and can also be used in a high temperature range. The aim is achieved by a method comprising the following steps: a) a flexible intermediate support layer is applied to a support film as a release layer; b) an embossed sol is applied to the intermediate support layer and is provided with a surface structure; c) a stack encompassing a binder layer and the surface structure is produced; d) the support film is removed; e) the workpiece is thermally treated.

A composition for producing optical elements has a gradient structure, particularly for holographic applications, wherein the gradient structure is formed by a refractivity gradient. The composition is produced from a polymer and a light- and/or temperature-sensitive metal complex and the light- and/or temperature-sensitive metal complex is decomposed upon changing the local refractivity. The result is the formation of a refractivity gradient.
