Description

Verfahren zur Herstellung von Gerbbildern unter Verwendung von Kolloiden Gegenstand des Patents 485 298 ist ein Verfahren zur Herstellung lichtempfindlicher Schichten und photographischer Bilder mittels Arylaziden. Nach diesem Verfahren werden die Farbstoffbilder in der Art hergestellt, daß man Arylazide auf eine Unterlage bringt und die entstandene lichtempfindliche Schicht unter einer Vorlage belichtet. An den vom Licht getroffenen Stellen bildet sich ein Farbstoff. Durch Entfernung der uniersetzten lichtempfindlichen Schicht wird die Kopie haltbar gemacht.Process for the production of tanning images using colloids The subject of patent 485 298 is a process for the production of photosensitive Layers and photographic images using arylazides. According to this procedure the dye images are produced in such a way that aryl azides are applied to a base brings and exposed the resulting photosensitive layer under an original. A dye forms at the points hit by the light. By distance The copy is made durable on the unieried photosensitive layer.

Gegenstand der vorliegenden Erfindung ist die Herstellung von Gerbbildern durch Belichten von Arylaziden in Kolloiden. Die mit Arylaziden durchsetzte Kolloidschicht erleidet an den vom Licht getroffenen Stellen eine intensive Gerbung, so daß hierdurch die Herstellung von Gerbbildern möglich ist, die eine ausgezeichnete Wiedergabe sämtlicher Tonwerte zeigen. Die erhaltenen Gerbbilder können in der üblichen, z. B. beim Chromatverfahren gebräuchlichen Weise weiter behandelt oder verarbeitet werden.The present invention relates to the production of tanning images by exposing aryl azides in colloids. The colloid layer interspersed with aryl azides suffers an intense tanning in the areas hit by the light, so that this the production of tanning images is possible, which has an excellent reproduction show all tonal values. The tanning patterns obtained can be used in the usual, e.g. B. further treated or processed in the usual manner in the chromate process will.

Als Kolloide können Gelatine, Fischleim, Kollodium u. dgl. benutzt werden, als Unterlage Glas, Film, Metallplatten, Papier usw.Gelatin, isinglass, collodion and the like can be used as colloids glass, film, metal plates, paper, etc.

Es sind zwar einige Farbstoffe der Phthaleingruppe bekannt, die beim Belichten Kolloide zu gerben vermögen (E der, Das Pigmentverfahren, q.. Aufl. S. 39), doch sind hierbei die Belichtungszeiten sehr groß und der Gerbeffekt nur gering, so d'aß eine praktische Verwendung dadurch ausgeschlossen ist. Gegenüber diesem Verfahren bringt die vorliegende Erfindung einen großen Fortschritt, da sie die Herstellung praktisch brauchbarer Gerbbilder bei kurzen Belichtungszeiten ermöglicht.Although some dyes of the phthalein group are known that are used in Exposing colloids to tanning (E der, Das Pigmentverfahren, q .. ed. P. 39), but the exposure times are very long and the tanning effect is only slight, so that a practical use is thereby excluded. Compared to this Method brings the present invention a great advance, since it the Allows production of practically usable tanning images with short exposure times.

Die nach dem vorliegenden Verfahren hergestellten Gerbbilder können mit besonders gutem Erfolg zum Drucken verwendet werden, indem man sie mit fetter Farbe einwalzt und die angenommene Farbe durch Drucken auf Papier überträgt. Durch die resultierende besondere Oberflächenstruktur der erfindungsgemäß gegerbten Kolloidschicht lasen sich auch ohne Einkopieren eines Rasters ausgezeichnete Ergebnisse erzielen.The tanning patterns produced by the present process can be used with particularly good success for printing by using them with bold Rolls in color and transfers the accepted color by printing on paper. By the resulting special surface structure of the colloid layer tanned according to the invention Excellent results can also be achieved without copying in a grid.

Außer Kolloiden und Arvlaziden können die zur Herstellung von Gerbbildern bestimmten Schichten noch Zusätze enthalten, wie sie bei dem Chromatv erfahren üblich sind; z. B. Glycerin, Zucker, hygroskopische Salze, Pigmente usw. In analoger Weise kann der O_uellzustand des Gerbbildes durch Säuren, Basen und Salzlösungen weitgehend beeinflußt werden.In addition to colloids and arvlazides, they can be used to produce tanning patterns certain layers still contain additives, as they are usually experienced with the Chromatv are; z. B. glycerine, sugar, hygroscopic salts, pigments, etc. in an analogous manner The original state of the tanning pattern can be largely due to acids, bases and salt solutions to be influenced.

ach dem beschriebenen Verfahren lassen sich nicht nur Gerbbilder in auffallendem Licht herstellen, sondern auch Reflexkopien, wobei die lichtempfindliche Schicht auf die Vorlage gelegt und dann durch die Schicht belichtet wird: Die Bilder können mit geeigneten Farbstoffen in üblicher Weise herausgearbeitet werden.After the process described, not only tanning patterns can be used in produce incident light, but also reflective copies, the photosensitive Layer on the Original placed and then exposed through the layer is: The images can be worked out in the usual way with suitable dyes will.

Beispiel Eine Emulsion, bestehend aus io Gewichtsteilen Gelatine, 3 Gewichtsteilen Natriumsalz der 5-Azido-2-oxybenzoesäüre, o,2 Gewichtsteilen Nickelchlorür, 0,3 Gewichtsteilen Bromalaun und i io Raumteilen Wasser wird auf eine Unterlage, z. B. Glas, Film oder Papier aufgebracht und nach dem Trocknen unter einer Vorlage belichtet. Man erhält ein braunes, negatives Gerbbild, das nach dem Behandeln mit einem Ouellmittel, beispielsweise Wasser, in üblicher Weise angefärbt oder mit fetter Färbe eingewalzt werden kann: Im letzteren Fall kann das Bild in bekannter Weise auf Papier umgedruckt werden.EXAMPLE An emulsion consisting of 10 parts by weight of gelatin, 3 parts by weight of the sodium salt of 5-azido-2-oxybenzoic acid, 0.2 parts by weight of nickel chloride, 0.3 parts by weight of bromoalum and 10 parts by volume of water is applied to a base, e.g. B. glass, film or paper applied and exposed after drying under a template. A brown, negative tanning pattern is obtained which, after treatment with a swelling agent, for example water, can be stained in the usual way or rolled in with a greasy dye: In the latter case, the image can be transferred to paper in a known manner.
