Zusatz zum Patent 250462 vom 5. März 1911.Addendum to patent 250462 from March 5, 1911.
Patentiert im Deutschen Reiche vom 28. Dezember 1911 ab. Längste Dauer: 4. März 1926.Patented in the German Empire on December 28, 1911. Longest duration: March 4, 1926.
Bei der weiteren Ausarbeitung der durch das Patent 250462 geschützten Erfindung hat sich gezeigt, daß auch die in einer Aminogruppe monoalkylierten Derivate des 2-5-Diamino-p-kresols wertvolle blaue Färbungen auf Pelzen und Haaren ergeben.In the further elaboration of the invention protected by patent 250462 it has been shown that the derivatives of 2-5-diamino-p-cresol monoalkylated in an amino group result in valuable blue colorations on fur and hair.
Die monoalkylierten 2 · 5-Diamino-p-kresole werden z.B. erhalten durch Ankuppeln einer Diazoverbindung an monoalkylierte o-Aminop-kresole und nachherige Reduktion des entstandenen Azofarbstoffes. Die freien Basen sind äußerst oxydabel, bilden aber beständige Salze, die in Wasser sehr leicht löslich sind. Die wäßrige Lösung der Salze wird durch Eisenchlorid rotviolett.The monoalkylated 2 x 5-diamino-p-cresols are obtained, for example, by coupling a Diazo compound on monoalkylated o-aminop-cresols and subsequent reduction of the resulting Azo dye. The free bases are extremely oxidizable, but form stable ones Salts that are very easily soluble in water. The aqueous solution of the salts is through Ferric chloride red-violet.
Die Färbungen werden z. B. in der Weise erzeugt, daß man die vorgebeizten oder ungebeizten Felle mit einer wäßrigen Lösung des Monoäthyl-2 · 5-diamino-p-kresols unter Zusatz von Wasserstoffsuperoxyd behandelt.The colorations are z. B. generated in such a way that one of the pre-pickled or unpickled Pelts with an aqueous solution of monoethyl-2 · 5-diamino-p-cresol with added treated by hydrogen peroxide.
Diese Färbungen zeichnen sich gegenüber den im Hauptpatent erwähnten durch eine wesentlich grünstichigere Nuance aus.These colorations are distinguished from those mentioned in the main patent by a a much greener shade.
