Description

Verfahren zur Herstellung von lichtempfindlichen Schichten und von Lichtbildern Zusatz zum Patent 467089 In dem Patent 467 o89 wurde ein Verfahren zur Herstellung von Lichtbilderh mit Schichten beschrieben, in denen als lichtempfindliche Stoffe Ketone verwendet werden; auf diesen Schichten können nach Belichtung in Gegenwart von Silbersalzen- Silberbilder entwickelt werden.Process for the production of light-sensitive layers and of light images Addition to the patent 467089 In the patent 467,089 a process for the production of light images with layers was described in which ketones are used as light-sensitive substances; on these layers, after exposure in the presence of silver salts, silver images can be developed.

Es wurde nun gefunden, daß auch andere organische Stoffe für das Verfahren entsprechend dem Hauptpatent geeignet sind, sofern sie lichtempfindlich sind oder sich nach der Herstellung des Bildes leicht wieder aus der Schicht entfernen lassen. Schleierfreie Bilder werden insbesondere bei ausgesprochen saurer Entwicklung erhalten.It has now been found that other organic substances are also suitable for the process are suitable according to the main patent, provided they are photosensitive or can be easily removed from the layer after the image has been created. Fog-free images are obtained in particular with extremely acidic development.

Aus technischen Gründen scheiden von den vorgenannten Stoffen solche aus, die leicht verdunsten, in den Schichten nicht festgehalten werden oder nicht haltbar sind. Aus bildmäßigen Gründen scheiden solche aus, die keine reinen Weißen ergeben oder die sich, wenn sie in den erforderlichen Mengen der Schicht einverleibt werden, nicht genügend auswaschen lassen. Beispiele für geeignete Stoffe sind Aminonaphtholverbindungen und andere Zwischenprodukte der Farbstoffabrikation sowie Farbstoffe selbst, die sich genügend aus Schicht und Schichtträgern wieder auswaschen lassen. Ferner sind z. B. organische Bleiverbindungen dazu geeignet, um Schichten herzustellen für die Erzeugung von Röntgenbildern nach dem Verfahren der Erfindung.For technical reasons, these are different from the aforementioned substances which evaporate easily, are not retained in the layers or not are durable. For pictorial reasons, those who are not pure whites are ruled out arise or when incorporated into the layer in the required quantities not wash out enough. Examples of suitable substances are aminonaphthol compounds and other intermediate products of dye manufacture, as well as dyes themselves, the can be washed out sufficiently from the layer and substrate. Furthermore are z. B. organic lead compounds suitable to produce layers for the Generation of X-ray images according to the method of the invention.

Beispiel io ccm einer kalt gesättigten und filtrierten Lösung von Flavindulin O 11 werden mit 5o ccm einer 8prozentigen Lösung von Gelatinegemisch mit i ccm 8prozentiger Chromalaunlösung versetzt, durch Glaswolle filtriert und bei 3o bis 35° auf Glas oder Papier vergossen (io ccm der fertigen Lösung auf 270 cm' Fläche). Nach schnellem Trocknen mit warmer Luft wird unter einem Negativ belichtet. Die Belichtungszeit beträgt etwa l/", bis l/", der von Celluidinpapier. Das Bild wird etwa i Minute lang in einer iprozentigen wäßrigen Silbernitratlösung gebadet, etwa 5 Sekunden lang in einer Mischung von ioo ccin destilliertem Wasser und i ccm iprozentiger Essigsäure abgespült und etwa a Minuten lang entwickelt in: Wässer 9o ccm, iprozentige p-Phenylendiaminlösung d. ccm, ioprozentige Essigsäure a ccm.Example 10 ccm of a cold saturated and filtered solution of flavindulin O 11 are mixed with 50 ccm of an 8 percent solution of gelatin mixture with 1 ccm of 8 percent chrome alum solution, filtered through glass wool and poured at 30 to 35 ° on glass or paper (10 ccm of the finished solution on 270 cm 'area). After rapid drying with warm air, exposure is carried out under a negative. The exposure time is about 1 / "to 1 /" that of celluidine paper. The image is bathed for about 1 minute in an aqueous silver nitrate solution, rinsed for about 5 seconds in a mixture of 100% distilled water and 1% acetic acid, and developed for about a minute in: 90 cc water, 100% p-phenylenediamine solution. cc, 10 percent acetic acid a cc.

Nach kurzem Abspülen wird in mit Kaliumtnetabisulfit schwach angesäuerter 5prozentiger N atriumthiosulfatlösung etwa 5 Minuten lang fixiert, mehrere Stunden lang gewässert und getrocknet. ,After a short rinse, it is made weakly acidic with potassium netabisulphite 5% sodium thiosulphate solution for about 5 minutes long fixed, Watered and dried for several hours. ,
