20110063709 | ELECTROCHROMIC FORMULATION WITH AT LEAST TWO DYE SYSTEMS, METHOD FOR PRODUCTION THEREOF AND ELECTROCHROMIC COMPONENT - Electrochemically active formulations may be used for flashing electrochromic displays, in particular for those that in addition to blinking can switch on a permanent symbol with the blinking display. The formulations contain at least two chemically different dye systems. The formulations provide a first dye system that is reversibly switchable at a low voltage, hence suitable for blinking representation of symbols. A second dye system is activated at a higher voltage and is suitable for permanent display of symbols due to the bistability or irreversibility thereof. | 03-17-2011 |
20120069418 | ELECTROCHROMIC FORMULATION, METHOD FOR THE PRODUCTION THEREOF, AND ORGANIC ELECTROCHROMIC COMPONENT - The service life of EC components can be substantially increased by eliminating the need for conducting salt additives, which can decompose the formulation by adverse reactions. At the same time, salt-like structures are formed by the active electrochromic components themselves. | 03-22-2012 |
20120069419 | ELECTROCHROMIC FORMULATION, METHOD FOR THE PRODUCTION THEREOF, AND ORGANIC ELECTROCHROMIC COMPONENT - Formulations can be used in organically based electrochromic components, such as for the production of state indicators, the activated state of which is maintained for as long as possible without an electric current. Organically based electrochromic formulations contain one or more optionally cathodically (coloring) activatable electrochromic coloring systems, as well as an anodically activatable antagonist formed of an amine which dimerizes to a hydrazinium salt by releasing an electron. Titanium dioxide is introduced as an image background (maximum opacity), and additionally a dispersant is introduced which can be crosslinked or partly crosslinked. | 03-22-2012 |

20090130489 | UV PROTECTIVE COMPOSITIONS, PROCESSES FOR PREPARING SUCH COMPOSITIONS, METHODS OF COATING SUBSTRATES THEREWITH AND MULTI-LAYER ARTICLES FORMED THEREBY - Compositions, suitable for coating surfaces, methods for their preparation and for coating surfaces therewith, where said compositions comprise: (a) 100,000 parts by weight of a primer composition comprising a binder material (a1), a primer solvent (a2) and a UV absorber (a3), wherein the primer composition is suitable as an adhesion-promoting agent between a thermoplastic substrate and a siloxane-based top coat; (b) 0 to 900,000 parts by weight of a solvent, and (c) 1 to 3000 parts by weight of a compound according to the general formula (I): | 05-21-2009 |
20120101210 | NOVEL AQUEOUS 2-COMPONENT PUR COATING SYSTEMS FOR IMPROVED CORROSION PROTECTION - The invention relates to novel aqueous two-component coating agents based on hydroxy and/or amino-functional water-dilutable resins and nanoparticle-modified isocyanate-functional curing agents, to a method for the production thereof, and to the use thereof in paints, coatings, and sealants, particularly for corrosion protection applications. | 04-26-2012 |
20120135213 | COEXTRUDED FILMS WITH LOW TEMPERATURE IMPACT RESISTANCE - The invention relates to multilayer products comprising a layer (A) and a layer (B), wherein layer (A) contains polyalkyl(alkyl)acrylate and has a layer thickness <25 [mu]m, and layer (B) contains polycarbonate. The total thickness of layers (A) and (B) is 20 to 500 mm. | 05-31-2012 |
