  • Patent number: 9399206
    Abstract: A process for producing encapsulated metal colloids useful as inorganic colored 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 colored 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%.

  • Patent number: 8133573
    Abstract: A process for producing a crystalline substrate with an optical multi-layer system thereon and the crystalline substrate obtainable thereby. The process comprises the successive application of at least two free-flowing compositions which comprise nanoscale inorganic solid particles comprising at least one of a polymerizable and a polycondensable organic group to a surface of the crystalline substrate and the polymerization and/or polycondensation of the organic groups of the solid particles to form organically crosslinked layers on the substrate and a single-stage thermal consolidation of these layers with a burnout of organic constituents thereof. The at least two compositions give rise to layers with different refractive indices.

  • Patent number: 8034435
    Abstract: The invention relates to a plastic film with an interference multilayer system applied thereon that comprises at least two layers. Said layers can be obtained by hardening and/or applying thermal treatment to a coating composition containing nanoscale inorganic solid particles having polymerizable and/or polycondensable organic surface groups, thereby forming a layer that is crosslinked by means of the polymerizable and/or polycondensable organic surface groups. The films can be used as an optical laminating film.

  • Publication number: 20100203308
    Abstract: 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.
