KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Hauptpatent 157411 bezieht sich auf ein Verfahren zum Umwandeln von Silberbildern in beständigere katalysierende Bilder, deren wirksame Substanz aus höheren Oxyden des Mangans besteht. Das Verfahren des Hauptpatents läßt sich auf Silberpositive gleichfalls anwenden, und es werden nach diesem Verfahren scharfe und gute Manganbilder erhalten. Diese Manganbilder haben mit den schon anderweitig hergestellten die Eigenschaft gemeinsam, daß sie sich mit Leichtigkeit mit Hilfe von Anilinchlorhydrat und dergl. färben lassen.The main patent 157411 relates to a method of converting silver images into more permanent catalyzing images, whose active substance consists of higher oxides of manganese. The procedure of the The main patent can also be applied to silver positives, and there are after This process obtained sharp and good manganese images. Have these manganese images with those already produced elsewhere the property has in common that they deal with Color lightly with the help of aniline chlorohydrate and the like.
Durch die vorliegende Erfindung wird es also ermöglicht, Silberbilder beliebiger Art und Herkunft durch einfache Behandlung so zu tonen, wie es bisher nicht möglich war. Man hat zwar den Silberbildern die bekannten graublauen, braunen, purpurbraunen bis schwarzen Töne bereits durch anderweitige Behandlung geben können, jedoch ist bekanntlich die Zahl und Art der Töne eine sehr beschränkte. Auch waren häufig die Verfahren umständlich und lieferten nicht mit Sicherheit das gewünschte Ergebnis.The present invention thus makes it possible to produce silver images of any kind and origin to be tinted by simple treatment in a way that was previously not possible. One has the well-known gray-blue, brown, purple-brown to silver pictures can already give black tones through other treatment, but is known the number and type of tones are very limited. The procedures were also frequent awkward and did not deliver the desired result with certainty.
Nachfolgendes Beispiel erläutert das Verfahren. The following example explains the procedure.
Bromsilberpositive werden nacheinander in folgende Bäder gebracht.Bromide silver positives are placed in the following baths one after the other.
-Bad I wird aus folgenden Lösungen A und B in der angegebenen Weise gemischt.-Bath I is mixed from the following solutions A and B in the specified manner.
Lösung A: 3 ecm ioprozentige Kaliumbromidlösung, 2 ecm ioprozentige Zitronensäurelösung, 3 ecm der untenstehenden Manganilösung.Solution A: 3 ecm io percent potassium bromide solution, 2 ecm io percent citric acid solution, 3 ecm of the one below Manganese solution.
Hierzu setzt man:To do this, one uses:
Lösung B: 20 ecm 2prozentige Ferricyankaliumlösung, 80 ecm Wasser.Solution B: 20 ecm 2 percent potassium ferricyanide solution, 80 ecm of water.
Zu Lösung A verwendete Manganisalzlösung: 150 g Natriumtartrat, 25gManganosulfat, kristallisiert, 100 ecm Normalnatronlauge, 100 ecm 4prozentige Kaliumpermanganatlösung. Manganese salt solution used for solution A: 150 g sodium tartrate, 25 g manganese sulfate, crystallized, 100 ecm normal sodium hydroxide solution, 100 ecm 4 percent potassium permanganate solution.
Nachdem die Bilder einige Zeit mit Bad I bis zum Verschwinden des Silbers behandelt worden sind, werden sie kurze Zeit ausgewaschen und dann in einAfter treating the pictures with bath I for some time until the silver disappears they are washed out for a short time and then turned into a
Bad II von 90 ecm 2prozentiger Ferricyankaliumlösung, 10 ecm Norm.alnatronlauge gebracht, worauf das Bild mit brauner Farbe erscheint.Bath II of 90 ecm 2 percent potassium ferricyanide solution, Brought 10 ecm of normal sodium hydroxide solution, whereupon the picture turns brown appears.
Die so entstandenen Manganbilder werden nun wiederum gewaschen und können in bekannter Weise beliebig, beispielsweise mit Anilinchlorhydrat, gefärbt werden.The resulting manganese images are now washed again and can be used in a familiar Any way, for example with aniline chlorohydrate, can be colored.
