Description

Verfahren zuni Färben von Pelzen, Haaren, Federn u. dgl. Wie gefunden wurde, lassen sich Naphthalinderivate, welche durch 4-Aminoarylaminogruppen der Benzolreihe substituiert sind, ausgezeichnet zum Färben von Pelzen, Haaren, Federn u.dgl. verwenden. Der Naphthalinrest kann außerdem noch substitniert sein, z.B. durch Oxy-, Amino-, Aminoarylaminogruppen.Method for dyeing fur, hair, feathers and the like. As found was, can be naphthalene derivatives, which by 4-aminoarylamino groups Benzene series are excellent for dyeing fur, hair, feathers and the like. The naphthalene residue can also be substituted, e.g. by oxy, amino, aminoarylamino groups.

Behandelt man das gebeizte oder ungebeizte Färbegut mit einer wäßrigen Lösung vonSalzen solcher 4-Aminoarvlaminoderivate des Naphthalins und dann mit einem geeigneten Oxvdationsmittel, so entstehen auf der Faser eilite rotviolette bis schwarzblaue und grünlichgraue Farbtöne.If the stained or unstained dyed material is treated with an aqueous one Solution of salts of such 4-Aminoarvlamino derivatives of naphthalene and then with one suitable oxidizing agents, then the fibers develop eilite red-violet to black-blue and greenish gray hues.

Beispiel i In einem Bade, das im Liter :2g 2-(4'-Aminophenylamino) - naplithalinchlorhydrat, etwas Alkohol und eine ganz geringe Üenge Chlorwasserstoffsäure enthält, wird das gut ,getötete und gegebenenfalls gebeizte Fell bei gewöhnlicher Temperatur einige Stunden behandelt. _N, ach dem Spülen folgt eine einstündige Behandlung in einem besonderen Bade, das im Liter 2o g Kaliumbichromat und 20 '," Essigsäure, 3oprozentig, enthält. Man erhält eine blaugraue Färbung, Ein mit Kaliumbichromat vorgebeiztes Fell wird blauer, wenn man es der ersten Behandlung nach dem Beispiel i und dann einer Nachbehandlung mit Wasserstoffsuperoxyd in amnioniakalischer Lösung unterwirft; eine Kupfervorbeize führt zu einer schwarzblauen Färbung.Example i In a bath containing 2g of 2- (4'-aminophenylamino) - naplithalin chlorohydrate, a little alcohol and a very small amount of hydrochloric acid per liter, the well-killed and, if necessary, stained fur is treated for a few hours at normal temperature. After rinsing, there is a one-hour treatment in a special bath that contains 2o g of potassium dichromate and 20 % acetic acid per liter. The result is a blue-gray coloration Treatment according to Example i and then subjected to an aftertreatment with hydrogen peroxide in amniotic fluid; a copper pre-pickling leads to a black-blue coloration.

Mit 1-(4-Aminophenylamino)-,naphthalin erhält man je nach den erwähnten Bedingungen rotviolette bis korinthfarbige Töne.With 1- (4-aminophenylamino) -, naphthalene, depending on the conditions mentioned, red-violet to corinth-colored tones are obtained.

Beispiel 2 In einem Bade, das im Liter 5 9 2-(4'-Aminophenylamino) -6- oxvnaphtlialinchlorlivdrat, etwas Alkohol und eine geringe Menge Chlorwasserstoffsäure enthält, wird das gut getötete und gegebenenfalls gebeizte Fell einige Stunden bei gewöhnlicher Temperatur behandelt. Nach dein Spülen wird mit Oxvdationsmitteln nachbehandelt. Eine angesäuerte Bichromatlösung liefert dabei dunkelgrünblaue Grautöne.Example 2 In a bath, the (4'-aminophenylamino) -6- oxvnaphtlialinchlorlivdrat in 5 liters of 9 2- containing a little alcohol and a small amount of hydrochloric acid is treated for several hours at ordinary temperatures well killed and optionally pickled hide. After rinsing, the skin is treated with oxidizing agents. An acidified bichromate solution produces dark green-blue gray tones.

Mit 2-(4'-Aminophenyl.amino)-6-(4'-aminoplienylamino)-naphtlialin erhält man ähnliche, mehr grünliche Grautöne; i-(4'-Amiliophenylamino) - 5 - (4' - aminopheilylamino") -ilaplitlialin liefert bei der Nachbehandlung mit einer Lösung von Alkalibichroinat und Essigsäure violettgraue Färbungen. I-W-Aminophenylamino) -5-oxynaphthalin gibt unter gleicfien Bedingungen ein Blauviolett, :2- (.4'-Aininophenylarnino) - 7 - oxynaplitlialin ein blaustichiges Violett, 2-(4'-Arninopheiivlamino) -7-(4'-aiiiiilophenylarnino - ) -naphthaiin ein violettstichiges Grau, Töne, welche bei län-erer Behandlung mit Biehromat und Essigsäure in violett- oder blaustichige Graufärbungen übergehen.With 2- (4'-aminophenyl.amino) -6- (4'-aminoplienylamino) -naphthalene, similar, more greenish gray tones are obtained; i- (4'-Amiliophenylamino) - 5 - (4 ' - aminopheilylamino ") -ilaplitlialin gives violet-gray colorations on aftertreatment with a solution of alkali bichroinate and acetic acid. IW-aminophenylamino) -5-oxynaphthalene gives a blue-violet, under the same conditions: 2- (.4'-Aininophenylarnino) - 7 - oxynaplitlialin a bluish violet, 2- (4'-Aminopheiivlamino) -7- (4'-aiiiiilophenylarnino -) -naphthaiin a violet-tinged gray, tones which after prolonged treatment with Biehromat and acetic acid turn into violet or bluish gray colors.

Eine Substitution der Phenylgruppe, z. B. durch Alkyl oder Halogen, beeinträchtigt nicht die Verwendbarkeit der erwähnten jKaplithalinderivate.Substitution of the phenyl group, e.g. B. by alkyl or halogen, does not affect the usability of the abovementioned caplithalin derivatives.
