Description

Herstellung von Diazotypien. Zusatz zum Patent 376385'r'). Im Patent 376385 ist gezeigt worden, daß sich von positiven Bildern unmittelbar positive Lichtpausen (oder aus negativen- Bildern negative Pausen) in der Weise herstellen lassen, daß man Diazoanhydride auf eine geeignete Unterlage aufträgt, die Schichtunter der Vorlage belichtet und alsdann das Bild durch Einführung in ein Bad von Fhenolen oder Aminen entwickelt. Als Di:azoanhydride werden die D'iazoverbindunb n der 1#2- oder 2#i Aminooxynaphthaline oder deren Derivate oder solche von heterozyklischen Verbindungen verwendet.Production of diazotypes. Addendum to patent 376385'r '). In the patent 376385 has been shown that positive images immediately produce positive blueprints (or negative pauses from negative images) in such a way that one applies diazo anhydrides to a suitable base, the layer under the template exposed and then the image by introducing it into a bath of phenols or amines developed. The diazo compounds of the 1 # 2 or 2 # i are used as di: azo anhydrides Aminooxynaphthalenes or their derivatives or those of heterocyclic compounds used.

Im Patent 381551 ist dann weiter gezeigt worden, - daß man vermittels der im Hauptpatente beschrierenen lichtempfindlichen Schichten Positive aus einem Positiv auch in der Weise herstellen kann, daß man die lichtempfindliche Schicht nach dem Belichten durch die Vorlage hindurch noch einige Zeit dem freien Licht aussetzt und die Schicht alsdann mit einem Alkali entwickelt.In the patent 381551 it was then further shown - that one mediates of the photosensitive layers described in the main patent positively from one Positive can also be produced in such a way that the light-sensitive layer after exposure through the original for some time to the free light and the layer is then developed with an alkali.

Es ist nun weiter gefunden worden, daß man Kopien mit Hilfe dieser Schichten auch auf folgende Weise ohne Flüssigkeiten entwickeln und fixieren kann.It has now been found that you can make copies with the help of this Layers can also develop and fixate in the following way without liquids.

Man setzt die unter der Vorlage belichtete, lichtempfindliche Schicht nach Wegnahme der Vorlage noch kurze Zeit dem freien Licht aus und bringt sie dann ins Dunkle. -An den nichtbelichteten Stellen bildet sich dann von selbst ein Farbstoff, indem die noch unzer-*) Früheres Zusatzpatent 381551. setzte Diazoverbindung und das durch die Nachbelichtung entstandene Produkt sich vereinigen. Es entsteht also aus einem Positiv ein Positiv oder aus einem Negativ ein Negativ.The light-sensitive layer exposed under the original is placed After removing the template, it is exposed to the open light for a short time and then brings it into the dark. -A dye then forms by itself in the unexposed areas, by the as yet uncompleted additional patent 381551. set diazo compound and the product created by the post-exposure unite. So it arises a positive a positive or a negative a negative.

Schneller erreicht man das Bild dadurch, daß man die Schicht nach dem Belichten durch :die Vorlage hindurch am Licht der Einwirkung eines gasförmigen Alkalis, wie Ammoniak, aussetzt.The picture can be reached more quickly by following the layer exposure through: the original through the light of the action of a gaseous Exposure to alkalis, such as ammonia.

Das Verfahren hat den großen Vorteil, daß es alle Entwickelungs- und Fixierungsflüssigkeiten sowie jegliches Tönen überflüssig macht und Bilder mit bester Deckung deshalb liefert, weil infolge Vermeidung von wäßrigen Bädern und Bädern überhaupt kein Farbstoff weggewaschen werden kann.The process has the great advantage that it is all development and Fixing fluids as well as any tones superfluous and images with the best Provides coverage because as a result of avoiding aqueous baths and baths no dye at all can be washed away.

Im allgemeinen eignen sich zu diesem Verfahren alle Diazoanhydride. -In general, all diazo anhydrides are suitable for this process. -
