Abstract: The invention relates to an laminated glass for use in vehicles or in architecture, having a selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight. According to the invention, an optical multi-layer system having a total solar transmission of TTS<40%, a transmission Tvis in the wavelength range of visible light >70% and a reflection Rvis in the wavelength range of visible light <12% is present on said laminated glass. For reflection upon vertical light incidence, it has a reflection colour according to ASTM 308 (illumination source D65 and standard observer 10°) within a colour space that is limited by the values Ra* from ?5 to 5 and Rb* from ?25 to ?40. Alone or in addition, the laminated glass has a reflection colour according to ASTM 308 for transmission and reflection upon verticle light incidence within a colour space (colour box) that is limited by the values Ra* from ?5 to 5 and Rb* from ?25 to ?40.

Abstract: The invention relates to multilayer systems for selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight, and to a method for producing said systems on suitable, preferably polymeric, carrier materials. Such a multilayer system of the invention is formed with at least one layer composed of silver or silver alloy, which is coated over the whole area on both surfaces with in each case a seed layer and a cap layer. In this case, the seed layer and cap layer are formed from dielectric material. These are ZnO and/or ZnO:X. In this case, at least one such multilayer system is formed on a flexible polymeric substrate, preferable a film which is optically transparent in the visible spectral range.

Abstract: The present invention relates to a process for the preparation of sulphonamide-substituted imidazotriazinones of the general formula (I) characterized in that compounds of the formula (II) are reacted with sulphuric acid and the products obtained are then reacted with thionyl chloride and converted in situ in an inert solvent using an amine into the compounds according to the invention and, if appropriate, reacted to give the corresponding salts, hydrates or N-oxides.

Abstract: The present invention relates to a thermodynamically stable modification of the active compound ramatroban of formula (I). The thermodynamically stable form is prepared either by melting of the metastable form and subsequent recrystallization or by seeding a solution of the metastable active compound with a seed crystal of the thermodynamically stable form. The thermodynamically stable active compound can be employed as an asthma agent.
