ADOLF TELLKAMPF in CHARLOTTENBURG. Verfahren zur Herstellung von Gelatineflachdruckformen.ADOLF TELLKAMPF in CHARLOTTENBURG. Process for the production of gelatin planographic printing forms.

Zusatz zum Patente 201968 vom 10. August 1905.Addendum to patents 201968 of August 10, 1905.

Patentiert im Deutschen Reiche vom 12. Januar 1906 ab. Längste Dauer: 9. August 1920.Patented in the German Empire on January 12, 1906. Longest duration: August 9, 1920.

In der Patentschrift 201968 ist ein Verfahren zur Herstellung von Gelatineflachdruckformen beschrieben worden, bei welchem eine noch nicht entwickelte Eisenlichtpause auf eine Gelatineschicht gelegt wird, welche ein die Gelatine durch Reaktion mit ferricyanwasserstoffsaurem Alkalisalz härtendes Eisenoxydulsalz enthält. Es hat sich nun gezeigt, daß an Stelle des in der Gelatineschicht vorhandenen Eisensälzes auch Schwermetallsalze, welche für sich keinerlei Einfluß auf die Gelatinelösung ausüben, verwendet werden können. Derartige Sake sind beispielsweise diejenigen des zweiwertigen Kobalts, Nickels, Kupfers und des einwertigen Silbers. Doch sind die Oxydationsstufen nicht von derselben Bedeutung wie bei den Eisensalzen. Das Verfahren ist im übrigen dasselbe wie bei dem Hauptpatent. Patent specification 201968 describes a process for the production of gelatin planographic printing forms has been described in which a not yet developed iron blueprint is placed on a gelatin layer, which is a The iron oxide salt hardening gelatine by reaction with the ferricyanide alkali salt contains. It has now been shown that instead of that present in the gelatin layer Iron salts also include heavy metal salts, which by themselves have no effect on the gelatin solution exercise can be used. Such sake are, for example, those of divalent cobalt, nickel, copper and monovalent silver. But they are The degrees of oxidation are not of the same importance as in the case of the iron salts. The procedure is otherwise the same as for the main patent.

Die folgenden Beispiele veranschaulichen die Zusammensetzung der zu verwendenden Gelatineschichten. The following examples illustrate the composition of the gelatin layers to be used.
