  Verfahren zum Entwickeln von unsichtbaren Wasserstoffsuperoxydbildern mit ammoniakalischen   Mangansalzlösungen.   



   Im Stamm-Patent ist im Beispiel 4 ein Verfahren beschrieben, um von einem mit Wasserstoffsuperoxyd behandelten katalysierenden Original einen Abdruck in der Weise herzustellen, dass zunächst durch Anprosson des mit Wasserstoffsuperoxyd behandelten OriginalsgegenPapiereinunsichtbaresWasserstoffsuperoxydbildhergestelltunddieses   durch Behandeln   mit einer   Mangansalzlösung unter Zusatz   von   Ammoniak   entwickelt wird. 
 EMI1.1 
   superoxyd.   Derartige Stoffe sind beispielsweise gewisse Ammoniumsalze, wie   Ammonium-   chlorid. Ammoniumsulfat, Ammoniumnitrat u. dgl., bei deren Gegenwart keine   Faltung     durch   das   Ammoniak   eintritt.

   Wird die Entwicklung des Wasserstoffsuperoxydbildes mit einer derartigen Lösung vorgenommen, so erhält man ein braunes Bild mit reinen Weissen. weiches besonders dazu geeignet ist, auch seinerseits wieder als katalysierendes Bild zu dienen, wodurch der Vorteil erreicht wird, dass es an Stelle der ursprünglichen, bisweilen empfindlichen Originale verwendet werden kann. Eine geeignete Lösung wird beispielsweise

   Vorteil benutzt werden.

  Process for developing invisible hydrogen peroxide images with ammoniacal manganese salt solutions.



   In Example 4 of the parent patent, a process is described for producing an impression of a catalyzing original treated with hydrogen peroxide in such a way that initially an invisible hydrogen peroxide image is produced by attaching the original treated with hydrogen peroxide to paper and this is developed by treatment with a manganese salt solution with the addition of ammonia.
 EMI1.1
   superoxide. Such substances are, for example, certain ammonium salts, such as ammonium chloride. Ammonium sulfate, ammonium nitrate and the like Like., In the presence of which no folding occurs by the ammonia.

   If the hydrogen peroxide image is developed with such a solution, a brown image with pure whites is obtained. which is particularly suitable for serving as a catalyzing image, which has the advantage that it can be used in place of the original, sometimes sensitive originals. A suitable solution is for example
 EMI1.2
   Advantage can be used.
