Description

Verfahren zur Herstellung photographischer Bilder in mit lichtempfindlichen organischen Farbstoffen und mit Sensibilisatoren durchsetzten Kolloidschichten Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Bildern mittels lichtempfindlicher Schichten auf geeigneten Unterlagen, wie Glas, Papier, Film usw. Die Unterlagen werden mit Schichten, bestehend aus Kolloiden (z. B. Gelatine, Fischleim usw.), lichtempfindlichen Farbstoffen und Ausbleichsensibilisatoren bedeckt. Durch die Einwirkung des Lichtes auf derartige Schichten tritt eine Veränderung des Kolloids infolge Fällung der Substanzen oder durch Gerbwirkung u. dgl. ein. Diese Fällungen oder Gerbwirkungen können nach der Belichtung verstärkt werden. Nachbehandlungen, etwa mit Säuren, Alkalien, aber auch neutralen Substanzen, wie Wasser u. dgl., sind wirksam.Process for making photographic images in photosensitive organic dyes and colloid layers interspersed with sensitizers The invention is a method for producing images by means of photosensitive Layers on suitable substrates, such as glass, paper, film, etc. The substrates are coated with layers consisting of colloids (e.g. gelatin, isinglass, etc.), light-sensitive dyes and fade sensitizers covered. Through the Exposure to light on such layers results in a change in the colloid as a result of precipitation of the substances or due to the tanning effect and the like. These felling or tanning effects can be enhanced after exposure. Follow-up treatments, for example with acids, alkalis, but also neutral substances such as water and the like effective.

Die unbelichteten Stellen nehmen aus Farbstofflösungen Farbstoffe an je nach der Konstitution des belichteten und des anfärbenden Farbstoffes, während die belichteten die zur Anfärbung verwendete Farbe abstoßen oder wieder auswaschen lassen oder umgekehrt, wie dies bereits bei Chromatverfahren bekannt ist. Die Farbe kann auch an den löslichen Stellen samt dem Bindemittel ausgewaschen werden, während die Farbe an den anderen verbleibt. Das Auswaschen der Farbe oder des Bindemittels kann gegebenenfalls, besonders bei Überexpositionen, durch Säure, wie Milchsäure, oder durch Alkalien, wie Ammoniak, befördert werden.The unexposed areas take dyes from dye solutions on depending on the constitution of the exposed and the dyeing dye, while the exposed repel the color used for staining or wash out again leave or vice versa, as is already known from chromate processes. The color can also be washed out at the soluble points together with the binder while the color remains on the other. Washing out the paint or the binder can possibly, especially in the case of overexposure, by acid, such as lactic acid, or by alkalis such as ammonia.

Das Verfahren kommt nicht nur zur Erzeugung direkter Bilder durch auffallendes Licht in Anwendung, sondern auch zur Herstellung von Reflexkopien, wobei in bekannter Weise die lichtempfindliche Schicht auf das Original gelegt und durch die Schicht belichtet wird, worauf die weitere Entwicklung und Anfärbung des Bildes folgt unter Anwendung geeigneter Farbstoffe (Eder o.183). Das Verfahren eignet sich infolgedessen für die reproduzierenden Druckverfahren, wie Offsetdruck usw.The method doesn't just get through to generating direct images incident light in use, but also for the production of reflex copies, wherein in a known manner the photosensitive layer is placed on the original and is exposed through the layer, whereupon the further development and coloring of the Image follows using suitable dyes (Eder o.183). The procedure is suitable As a result, the reproductive printing processes, such as offset printing, etc.

Die belichtete Schicht kann auch mit fetter Farbe eingewalzt und dann an den nicht druckenden Stellen ausgewaschen werden. Das Bild kann mit trockener Farbe nach Art des Buridruckes eingestäubt werden.The exposed layer can also be rolled in with bold paint and then be washed out at the non-printing areas. The picture can be dry with Paint can be dusted in the manner of Buri printing.

Für die Ausführung dieses Verfahrens kommen Farbstoffe aus den verschiedensten Gruppen in Frage, genannt seien z. B. Phtaleine, Diphenyl-und Triphenylmethanfarbstoffe, Xanthonfarbstoffe, Azine, Oxazine, Thiazine, aber auch Pflanzenfarbstoffe, die alle in Gegenwart von Ausbleichsensibilisatoren zur Anwendung gelangen. Selbstverständlich kann man auch Mischungen der verschiedensten Farbstoffe anwenden.A wide variety of dyes are used to carry out this process Groups in question, such as B. phthaleins, diphenyl and triphenylmethane dyes, Xanthone dyes, azines, oxazines, thiazines, but also vegetable dyes, all of them be used in the presence of fading sensitizers. Of course you can also use mixtures of the most varied of dyes.

Zu bemerken ist, daß Farbstoffe für ähnliche Zwecke bereits vorgeschlagen wurden (Eder, Das Pigmentverfahren, q.. Aufl., S. 3g). Hierbei wurde jedoch nicht die günstige Wirkung von Ausbleichsensibilisatoren für ein derartiges Verfahren erkannt.It should be noted that dyes have already been proposed for similar purposes (Eder, Das Pigmentverfahren, q .. ed., p. 3g). However, this was not done the beneficial effect of bleach sensitizers on such a procedure recognized.

Außer Kolloid, Farbstoff und Sensibilisatoren können derartige Schichten noch die verschiedensten Zusätze, wie diese z. B. bei Chromatschichten üblich oder bekannt sind, enthalten, genannt seien: Pigmente, Seife, Zucker, Glycerin und ähnliches.In addition to colloid, dye and sensitizers, such layers can be used nor the various additives, such as these z. B. with chromate layers common or are known, contain, may be mentioned: pigments, soap, sugar, glycerin and similar.

Unter Gerbwirkung werden in vorstehender Beschreibung die unter diesem Begriff zusammengefaBten Veränderungen von Löslichkeit, Quellbarkeit, Absorption u. ä. verstanden.Under the tanning effect in the description above, those under this Term summarized changes in solubility, swellability, absorption and the like understood.

Statt die lichtempfindlichen Schichten auf Unterlagen, wie Glas, aufzubringen, kann man sie gegebenenfalls selbst als Film verwenden. Beispiel 3,5 Teile Gelatine, o,o5 Teile Eosin, 2 Teile Thiosinamin und ioo Teile Wasser werden zu einer Emulsion verarbeitet und; wie für Reflexphotographie üblich, in dünnen Schichten auf passende Träger gegossen. Nach dem Trocknen der Schicht belichtet man, wäscht mit warmem Wasser aus und färbt an.Instead of applying the light-sensitive layers to substrates such as glass, you can use them yourself as a film if necessary. Example 3.5 parts of gelatin, 0.05 parts of eosin, 2 parts of thiosinamine and 100 parts of water form an emulsion processed and; as usual for reflex photography, in thin layers on suitable Cast carrier. After the layer has dried, it is exposed to light and washed with warm Water out and stains.
