erhalten z. B. durch Ankuppeln von o-Aminop-kresol oder m-Amino-p-kresol und nachherige Reduktion des Azofarbstoffs, auf Pelzen und Haaren besonders wertvolle blaugraue bzw. blaue Färbungen ergibt. Dies ist um so überraschender, da das nächstniedere Homologe, das· 2 · 5-Diaminophenol, völlig unbrauchbare Färbungen von ganz anderer Farbe liefert. receive z. B. by coupling o-aminop-cresol or m-amino-p-cresol and afterwards Reduction of the azo dye on furs and hair gives particularly valuable blue-gray or blue colorations. This is so more surprising, since the next lower homologue, the · 2 · 5-diaminophenol, is completely unusable Provides dyeings of a completely different color.

Die Färbungen werden z. B. in der Weise erzeugt, daß man die mit Chrom-, Kupferoder Eisensalzen oder Mischungen dieser gebeizten Felle mit der wäßrigen Lösung des 2 · 5-Diamino-p-kresols unter Zusatz von Wasserstoffsuperoxyd behandelt. Die so erhaltenen Färbungen zeichnen sich insbesondere durch große Fülle und hervorragende Echtheit aus.The colorations are z. B. generated in such a way that one with chromium, copper or Iron salts or mixtures of these pickled skins with the aqueous solution of the Treated 2 · 5-diamino-p-cresols with the addition of hydrogen peroxide. The so obtained Dyeings are characterized in particular by great abundance and excellent fastness.
