20080261053 | Abrasion-Resistant and Scratch-Resistant Coatings Having a Low Index of Refraction on a Substrate - Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment. | 10-23-2008 |
20090035703 | Regeneratable, structured plate comprising oxidation catalysts - A regeneratable plate having a structured surface comprising hydrophilic and hydrophobic regions. The plate comprises a substrate, a first layer comprising a hydrophilic oxidation catalyst arranged on the substrate, and a second layer which is hydrophobic and is imagewise arranged on the first layer to thereby afford the structured surface comprising hydrophobic regions and hydrophilic regions. A process for making the plate by imagewise exposure is also described. | 02-05-2009 |
20090141359 | PLASTIC FILM WITH A MULTILAYERED INTERFERENCE COATING - A polymer film with an optical interference system. The optical interference system comprises at least two layers of different refractive index, which layers comprise nanoscale inorganic particles having organic surface groups that are polymerizable and/or polycondensable. The layers are at least partially crosslinked through the organic surface groups. | 06-04-2009 |
20100178491 | ULTRA-HARD COMPOSITE LAYERS ON METAL SURFACES AND METHOD FOR PRODUCING THE SAME - The invention relates to a metal substrate comprising an ultra-hard composite layer consisting of an inorganic, vitreous matrix containing one or more abrasive fillers. According to the invention, the diameter of the filler particles or, if the filler particles have a platelet-type form, the thickness of the filler particles is less than the layer thickness of the composite layer. | 07-15-2010 |
20100203308 | Production of a flexible, gas-tight,and transparent composite film - The invention relates to a method for the production of a flexible, gas-tight, and transparent composite film, comprising a transparent carrier layer made of plastic and a glass-like layer. The method comprises the following steps: a) a temperature-resistant substrate is coated with a lacquer comprising glass or glass-forming pre-stages by a wet chemical process, b) the coating is thermally compressed to form the glass-like layer, c) the transparent carrier layer made of plastic is applied onto the glass-like layer and bonded thereto, and d) the composite of the carrier layer and the glass-like layer is separated from the substrate. The composite films obtained in this way are suitable as encapsulation material or packing material, particularly for the use in displays, illumination and photovoltaics, for example for light-emitting diodes, solar cells, displays, or electronic circuits. | 08-12-2010 |

20120266780 | PROCESS FOR PRODUCING ENCAPSULATED METAL COLLOIDS AS INORGANIC COLOURED PIGMENTS - A process for producing encapsulated metal colloids useful as inorganic coloured pigments, including, reacting one or more glass-forming components according to the sol-gel process to obtain a sol dispersing a metal salt in the resulting sol in the presence of an additional reducing agent to form metal colloids, converting the resulting dispersion into xerogel-encapsulated metal colloids by spray drying, heating the resulting xerogel-encapsulated metal colloids to density them. The present invention relates, furthermore, to inorganic coloured pigments, in particular producible by the process of the invention, including metal colloids produced from metal salts and encapsulated in an encapsulation, the encapsulation being produced from glass-forming components according to the sol-gel process and being densified to a xerogel or glass, the proportion of metal colloid in the capsules being at least 80%. | 10-25-2012 |
20140017399 | ABRASION-RESISTANT AND SCRATCH-RESISTANT COATINGS HAVING A LOW INDEX OF REFRACTION ON A SUBSTRATE - Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment. | 01-16-2014 |
