Description

Verfahren zur Herstellung feuchtigkeits- und temperaturbeständiger Lichtfilter Zusatz zum Patent 763 468 In den Patenten 767 468 und 767 724 wird ein Verfahren zur Herstellung feuchtigkeits- und temperaturbeständiger Lichtfilter beschrieben, das im wesentlichen dadurch gekennzeichnet ist, daß eingefärbte Folien auf einem temperaturbeständigen Glas befestigt und dann mit einer wasser- und temperaturbeständigen organischen Schicht überzogen werden.Process for the production of moisture- and temperature-resistant light filters Addendum to patent 763 468 Patents 767 468 and 767 724 describe a process for the production of moisture- and temperature-resistant light filters, which is essentially characterized in that colored films are attached to temperature-resistant glass and then be coated with a water and temperature resistant organic layer.

Bei der weiteren Entwicklung dieses Gegenstandes hat sich gezeigt, daß das Verfahren ganz besonders auch zur Herstellung von Tageslichtfiltern, Monochromatfiltern und von Luftschutzfiltern, die der fortschreitenden Entwicklung der Ultrarottechnik gerecht werden, geeignet ist. Dadurch, daß man entweder den nach dem Verfahren angewandten Folien, der Überzugsmasse oder dem Unterlagglas oder zweien oder allen dreien dieser Teile ultrarotabsorbierende Substanzen einverleibt, hat man eine weitgehende Variationsmöglichkeit, die es vor allem gestattet, möglichst solche Körper einzubauen, und zwar beliebig viele, welche wohl das störende Ultrarot in gewünschtem Ausmaß beseitigen, dabei aber trotzdem den auszunutzenden Spektralbereich möglichst wirtschaftlich durchlassen.In the further development of this object it has been shown that the process is particularly suitable for the production of daylight filters, monochromatic filters and of air protection filters, the advancing development of the ultrared technology be fair, is appropriate. By either using the method used according to the procedure Foils, the coating compound or the underlay glass or two or all three of these Incorporating parts of ultra-red absorbing substances, there is a wide range of options available, which above all allows such bodies to be built in as much as possible, in any way many, which probably the disturbing ultra-red to the desired extent remove, but nevertheless the spectral range to be used as economically as possible let through.

Diese letztere Forderung wird an und für sich gerade durch die im Hauptpatent beschriebene Verwendung gefärbter Folien besonders gut erfüllt, beispielsweise von Folien, die mit dem aus 1, 4, 5, 8-Naphthovlendibenzimidazol durch Behandlung mit starker Schwefelsäure gemäß Patent 536 911 abgeschiedenen, orange färbenden Küpenfarbstoff gefärbt wurden. Bei dem erfindungsgemäßen Verfahren wird ferner auch die geforderte, besonders scharfe spektrale Begrenzung erreicht, und zwar viel zuverlässiger und besser wiederholbar als durch Glasflüsse, Spritzen oder Anstriche. Es handelt sich also auch im vorliegenden Fall um die technische Herstellung sehr allgemein art-tvendbarer Filter, bei denen im Gegensatz zum Hauptpatent sämtliche Bauelemente zur optischen Korrektur herangezogen werden.This latter requirement is in and of itself met particularly well by the use of colored foils described in the main patent, for example foils that are deposited with the one from 1, 4, 5, 8-naphthovlenedibenzimidazole by treatment with strong sulfuric acid according to patent 536 91 1, orange-staining vat dye. In the method according to the invention, the required, particularly sharp spectral limitation is also achieved, and in fact much more reliably and more repeatably than by glass flows, spraying or painting. In the present case, too, it is a matter of the technical production of very general type-reversible filters, in which, in contrast to the main patent, all components are used for optical correction.
