Description

Verfahren zur Herstellung von Diazolichtbildern Durch die deutsche Patentschrift 422 972 ist bekannt, daß sich Diazoverbindungen, die einen ähnlichen Charakter wie die Diazoanhydride haben, also gefärbt und beständig sind, zur Herstellung von lichtempfindlichen Schichten eignen. In der Patentschrift werden besonders Aniinodiazoverbindungen für Schichten empfohlen, die sowohl die Diazokomponente als auch die Azokomponente enthalten. Von Diazoverbindungen sind besonders Ami.nodiphenyl@am,ine und Diazoakylaniline gemannt.Process for the production of diazo light images by the German Patent 422,972 is known that diazo compounds that have a similar Character like the diazo anhydrides have, i.e. they are colored and stable, for production of photosensitive layers. Aniinodiazo compounds are particularly mentioned in the patent Recommended for layers containing both the diazo component and the azo component contain. Of diazo compounds, ami, nodiphenyl @ am, ines and diazoakylanilines are particularly important manned.

Es ist nun gefunden worden, daß sich die Diazoverbindungen aus halogenierten Aminomonoalkylarylaminen, besonders die aus den Paraverbindungen, für solche Diazotypieverfahren, bei denen die Diazoverbindung sich allein auf der Unterlage befindet und eine Entwicklung durch ein alkalisches Bad einer Az.okomponente vorgenommen werden muß, besonders gut eignen. Nimmt man nicht halogenier te Verbindungen, so ist es schwierig, scharfe Kopien zu erhalten, da .die Linien stärker zum Auslaufen neigen.It has now been found that the diazo compounds are halogenated Aminomonoalkylarylamines, especially those from the para compounds, for such diazotype processes, in which the diazo compound is alone on the base and a development must be made by an alkaline bath of an Az.okomponente, especially well suited. If you use non-halogenated compounds, it is difficult to get sharp Copies as the lines tend to run out more.

Außer den Halogenatomen können die Diazoverbindungen im aromatischen Kern noch andere Gruppen, wie z. B. Allcyl-, Aralkyl-, Oxalkyl- und Alkyloxygruppen, enthalten. Am besten geeignet als Azokomponenten sind mehrwertige Phenole und Aminooxyverbindungen. Beispiel 2o Gewichtsteile des Chlorzinndoppelsalzes der Diazoverbindung des q.-Amino-3-chlor-6-methyl-z-monoäthylanilins, 2o Gewichtsteile Weinsäure, 2o Gewichtsteile Borsäure und 3o Gewichtsteile Thioharnstoff werden zusammen mit Wasser von etwa 35° gelöst und die Lösung, wie üblich, auf Papier oder eine andere Unterlage aufgestrichen.In addition to the halogen atoms, the diazo compounds in the aromatic Kern still other groups, such as B. alkyl, aralkyl, oxalkyl and alkyloxy groups, contain. The most suitable azo components are polyhydric phenols and aminooxy compounds. Example 2o parts by weight of the chlorotin double salt of the diazo compound of q-amino-3-chloro-6-methyl-z-monoethylaniline, 2o parts by weight of tartaric acid, 2o parts by weight of boric acid and 3o parts by weight of thiourea are dissolved together with water at about 35 ° and the solution, as usual, on paper or another surface.

Nach der Belichtung unter einer Vorlage entwickelt man durch Antragen der alkalischen Lösung der Azokomponente mittels einer Gummiwalze. Die Lösung kann z. B. 30 g Soda, 5 g Trinatr iumphosphat, z oo g Salz und 39 Phloroglucin, in rooo ccm Wasser enthalten.After exposure under an original, development is carried out by applying the alkaline solution of the azo component using a rubber roller. The solution can e.g. B. 30 g of soda, 5 g of trisodium phosphate, z oo g of salt and 39 phloroglucine, contained in 100 cc of water.

Man erhält tief dunkelbraune bis schwarze Bilder auf weißem Grund.Deep dark brown to black images are obtained on a white background.
