Description

Verfahren zur Herstellung ultraviolettes Licht absorbierender Produkte. Es wurde gefunden, daß man beim Auflösen von Oxychinolinsulfosäuren und ihren Abkömmlingen in verschiedenen Solventien, z. B. in 'Wasser oder bei der Einverleibung ihrer Lösungen in Salben, Pasten usw., zu Produkten gelangt, welche gut wirkende Lichtfilter gegen ultraviolette Strahlen darstellen, da sie das gesamte ultraviolette Spektrum zu absorbieren vermögen.Process for the manufacture of products which absorb ultraviolet light. It has been found that dissolving oxyquinoline sulfonic acids and their derivatives in various solvents, e.g. B. in 'water or in the incorporation of their solutions in ointments, pastes, etc., comes to products that work well against light filters represent ultraviolet rays as they cover the entire ultraviolet spectrum able to absorb.

Als ähnlich wirkende Stoffe sind z. B. bereits die Naphthol- und Naphthilaminsulfosäuren beschrieben; ihnen gegenüber zeichnen sich die nach vorliegendem Verfahren herstellbaren Präparate durch eine glückliche Vereinigung einer Reihe von vorzüglichen Eigenschaften aus. Die Lösungen, Salben usw., die unter Verwendung von Oxychinolinsulfosäuren und ihren Abkömmlingen (Salze, Ester usw.) hergestellt werden, absorbieren nämlich, selbst wenn sie die Substanz nur in großer Verdünnung enthalten, die ultravioletten Strahlen praktisch restlos; ferner sind die Lösungen im Gegensatz zu denen der obengenannten Stoffe außerordentlich beständig und dunkeln infolgedessen nicht nach. Auf Papier, Geweben o. dgl. entstehen beim Eintrocknen von Lösungen der hier beanspruchten Körper im Gegensatz zu der Anwendung mancher bekannter Lichtfilter keine gefärbten Flecken. Weiterhin wird ihre Wirksamkeit durch den sauren Charakter der Lösungen keineswegs beeinträchtigt. Während in der obenerwähnten Veröffentlichung die blaue Fluoreszenz als besonderes Merkmal der Naphthol- und Naphthylaminsulfosäuren hervorgehoben ist, besitzen die vorliegenden Körper keinerlei Fluoreszenz, was für manche Anwendungszwecke von Vorteil ist.As substances with a similar effect are z. B. already the naphthol and naphthilamine sulfonic acids described; in contrast to them, those that can be produced by the present process stand out Preparations through a happy combination of a number of excellent properties the end. The solutions, ointments, etc. made using oxyquinoline sulfonic acids and their derivatives (salts, esters, etc.), namely absorb, even if they contain the substance only in great dilution, the ultraviolet ones Radiance practically completely; furthermore, the solutions are contrary to those of the above Fabrics are extremely durable and as a result do not darken. On paper, Tissues or the like are created when solutions of the bodies claimed here dry out In contrast to the application of some known light filters, no colored spots. Furthermore, their effectiveness is in no way reduced by the acidic character of the solutions impaired. While in the above-mentioned publication the blue fluorescence is highlighted as a special feature of naphthol and naphthylamine sulfonic acids, the present bodies have no fluorescence whatsoever, which is for some purposes is beneficial.

Von den Abkömmlingen der Oxychinolinsulfosäuren kommen, wie gefunden wurde, in erster Linie deren Salze und Äther in Betracht. U. a. haben sich gut bewährt: 8-Methoxychinolin-5-sulfosäure: Schmelzpunkt 30a° unter Zersetzung; entsprechende Athoxyverbindung : Schmelzpunkt z83° unter Zersetzung; 6 - methoxychinolin - 5 - sulfosaures Natrium: Schmelzpunkt der freien Säure 3q.5° unter Zersetzung.From the derivatives of the oxyquinoline sulfonic acids come as found primarily their salts and ethers. I.a. have proven themselves well: 8-methoxyquinoline-5-sulfonic acid: melting point 30 ° with decomposition; appropriate Ethoxy compound: melting point 83 ° with decomposition; 6 - methoxyquinoline - 5 - Sodium sulphate: melting point of the free acid 3q.5 ° with decomposition.

Die Überführung in Lösungen, Salben, Pasten usw. kann unter Anwendung üblicher Methoden erfolgen.The transfer into solutions, ointments, pastes, etc. can be done using usual methods.

Die nach der Erfindung herstellbaren Lichtfilter sollen Anwendung finden für alle Zwecke, bei welchen es auf die Ausschaltung oder Absorption ultravioletten Lichts ankommt, so z. B. vornehmlich als Schutz von Gegenständen, Waren, wie z. B. Kupferstichen, gefärbter Textilwaren usw., insbesondere solcher, welche in Schauauslagen der Einwirkung des Lichtes unterworfen sind, ferner bei der Herstellung von Platten, Filmen usw. Man kann sie auch dazu verwenden, um Auge und Haut gegen die Einwirkung der ultravioletten Strahlen zu schützen.The light filters that can be produced according to the invention are intended to be used found for all purposes in which there is the elimination or absorption of ultraviolet Light arrives, so z. B. primarily as protection of objects, goods such. B. copperplate engravings, dyed textiles, etc., especially those in display cases are subject to the action of light, also in the manufacture of panels, Films, etc. They can also be used to protect the eyes and skin against the effects to protect from ultraviolet rays.

In allen diesen Fällen können neben den genannten Substanzen auch andere für die erwähnten Zwecke brauchbaren Stoffe zur Verwendung gelangen. Durch den Gebrauch der pulverförmigen Produkte selbst kann der erstrebte Effekt nicht herbeigeführt werden.In all of these cases, in addition to the substances mentioned, other substances that can be used for the purposes mentioned are used. By the use of the powdered products themselves may be the most sought after Effect cannot be brought about.
