Description

Verfahren zur Herstellung von lichtempfindlichen Schichten Es wurde 'gefunden, -daß man mit Hilfe von Arylaziden der allgemeinen Formel R - N3 (R - aryl), die man in bekannter Weise. z. B. durch Umsetzung von Diazoverbindungen mit stickstoffwasserstoffsauren Salzen herstellen kann, lichtempfindliche Schichten erzeugen kann.Process for the preparation of photosensitive layers It has been 'found -that one can use arylazides of the general formula R - N3 (R - aryl), which you can use in a known manner. z. B. by reacting diazo compounds with Nitrogen acid salts can produce photosensitive layers can generate.

Zu diesem Zweck löst man die Arylazide in Wasser oder organischen Lösungsmitteln, wie z. B. Alkohol, auf und trägt die Lösungen auf eine Unterlage, z. B. Papier oder Film, auf. Bei der Belichtung solcher Schichten bilden sich an den Stellen, an welchen das Licht einwirkt, Farbstoffe, während die vom Licht nicht getroffenen Stellen unverändert bleiben. Man erhält also durch Belichten hinter einem Negativ ein positives Bild. Die Farbe der Bilder ist von der Wahl der Arylazide abhängig, und man hat es in der Hand, durch Verwendung von Ary 1-aziden mit bestimmten Substituenten Bilder in allen möglichen Farben, wie Gelb, Braun, Rot, Violett bis Schwarz, herzustellen.For this purpose, the arylazides are dissolved in water or organic Solvents such as B. alcohol, and carries the solutions on a pad, z. B. paper or film. When such layers are exposed, they form the places where the light acts, dyes, while those from the light do not affected areas remain unchanged. So you get behind by exposure a negative a positive image. The color of the pictures depends on the choice of aryl azides dependent, and one has it in hand, by using ary 1-azides with certain Substituent pictures in all possible colors, like yellow, brown, red, up to purple Black to manufacture.

Die Farbtöne kann man weiter durch Zusatz vonBasen, Säuren oderMetallsalzenbeeinflussen. Auch kann -man die Arylazide in Gegenwart von - Kolloiden, z. B. Gelatine, Kollodium u. a., anwenden. Nach dem Belichten genügt ein einfaches Auswaschen der untersetzten Substanz mit Wasser oder einem anderen geeigneten Lösungsmittel, um die Bilder haltbar zu machen.The color tones can be further influenced by adding bases, acids or metal salts. The arylazides can also be used in the presence of colloids, e.g. B. gelatin, collodion among others, apply. After exposure, it is sufficient to simply wash out the stocky ones Substance with water or another suitable solvent to make the images more durable close.

Beispiel Man bestreicht Papier mit einer 3prozentigen neutralen oder schwach alkalischen, wäßrigen Lösung des Umsetzungsproduktes von Diazosalicylsäure mit Natriumazid, belichtet unter einem Negativ und wäscht das entstandene Bild mit Wasser. Man erhält eine braune, positive Kopie. Stellt man die lichtempfindliche Lösung schwach sauer, so erhält man eine gelbstichige Kopie.Example Paper is coated with a 3 percent neutral or weakly alkaline, aqueous solution of the reaction product of diazosalicylic acid with sodium azide, exposed under a negative and washes the resulting image with it Water. A brown, positive copy is obtained. If you put the photosensitive If the solution is weakly acidic, a yellowish copy is obtained.
