Verfahren zur Erzeugung wa8ch- und lichtechter FArbungen auf der Faser.
Es wurde gefunden, dass durch Kombination der l-Diazonaphtalm-2'sulfosaure mit a-Naphtylamin, Diazotierung des so erhaltenen Zwischenproduktes und Kupplung mit 2-Amino-5-oxynaphtalin-7-sulfosäure ein Farbstoff entsteht, der nach dem Weiterdiazotieren auf der Faser und Kuppeln mit einem Naphtnl wertvolle wasch-und lichtechte Färbungen liefert.
Beispiel 1.
24'5 Teile des Natriumsalzes der l-Aminonaphtalin-2-sulfosäure werden in Wasser gelöst und in üblicher Weise mittels Natriumnitrit + Salzsäure diazotiert. Zu der erhaltenen Diazoverbindung gibt man dann 14-3 Teile oc-Naphtylamin, in Wasser und Salzsäure gelöst, hinzu, desgleichen während der Reaktion eine entsprechende Menge Kalziumkarbonat, um die überschüssige Säure zu binden. Nach beendeter Kupplung wird der Monoazofarbstoff abfiltriert und gewaschen. Hierauf wird er durch Zugabe von Soda in das Natriumsalz umgewandelt, mit Natriumnitrit + Salzsäure diazotiert und die gebildete Diazoverbindung nach dem Abfiltrieren gewaschen.
Man rührt sie alsdann mit kaltem Wasser an und lässt sie in 24 Teilen in kaltem Wasser gelöster 2-Amino-5-oxynaphtalin- -7-sulfosäure unter Zugabe von Soda einlaufen. Das erhaltene Produkt wird abfiltriert, gewaschen und getrocknet.
Der Disazofarbstoff bildet ein bronzig schimmerndes Pulver, das in Wasser mit rotvioletter Farbe löslich ist. Säuren fällen aus dieser Lösung die Farbstoffsäure in Form violetter Flocken, während beim Zusatz von Alka1ihydroxydeu die Farbe der Lösung nach
Blau umschlägt, wobei das Alkalisalz des Farbstoffes gefällt wird. Es löst sich in Alkohol mit kirschroter, in konzentrierter Schwefelsäure mit bläulichschwarzer Farbe ; in Äther ist es unlöslich und nahezu unlöslich auch in Benzin.
Zur Entwicklung des Farbstoffes auf der Faser bedient man sich der für Diazo- tierungs- und Entwicklerfarbstoffe allgemein üblichen Methode.
Beispiel 2.
Die mit dem nach Beispiel 1 erhaltenen Diazofarbstoff gefärbte Baumwolle wird durch ein Bad wässeriger salpetriger Säure gezogen. Wenn die ursprüngliche Färbung verschwunden ist, geht man mit der Ware in ein alkalisches Bad von -Naphtolnatrium ein. Die Kupplung ist nach einigen Umzügen beendet. Die erzielte Färbung stellt ein waschechtes Blau dar, während die ursprüngliche Färbung ein waschunechtes Violett war.
Mit analog zusammengesetzten Farbstoffen, die an erster Stelle andere Komponenten enthalten, können-selbst nach der Entwicklung mit ss-Naphtol-keine Färbungen erreicht werden, die bei gleich guter Lichtechtheit eine ähnliche Waschechtheit besitzen.

Process for creating color and lightfast colors on the fiber.
It has been found that the combination of 1-diazonaphthalene-2-sulfonic acid with a-naphthylamine, diazotization of the intermediate product thus obtained and coupling with 2-amino-5-oxynaphthalene-7-sulfonic acid produces a dye which, after further diazotization, is produced on the fiber and domes with a naphtha provide valuable washable and lightfast colors.
Example 1.
24'5 parts of the sodium salt of l-aminonaphthalene-2-sulfonic acid are dissolved in water and diazotized in the usual way using sodium nitrite + hydrochloric acid. 14-3 parts of oc-naphthylamine, dissolved in water and hydrochloric acid, are then added to the diazo compound obtained, as is an appropriate amount of calcium carbonate during the reaction in order to bind the excess acid. When the coupling has ended, the monoazo dye is filtered off and washed. It is then converted into the sodium salt by adding soda, diazotized with sodium nitrite + hydrochloric acid and the diazo compound formed is washed off after filtering off.
It is then stirred with cold water and allowed to run in 24 parts of 2-amino-5-oxynaphthalene-7-sulfonic acid dissolved in cold water with the addition of soda. The product obtained is filtered off, washed and dried.
The disazo dye forms a bronzy shimmering powder that is soluble in water with a red-violet color. Acids precipitate the dye acid from this solution in the form of violet flakes, while when alkali hydroxide is added the color of the solution changes
Turns blue, precipitating the alkali salt of the dye. It dissolves in alcohol with a cherry-red color, in concentrated sulfuric acid with a bluish-black color; it is insoluble in ether and almost insoluble in gasoline.
The method generally used for diazotizing and developer dyes is used to develop the dye on the fiber.
Example 2.
The cotton dyed with the diazo dye obtained in Example 1 is drawn through a bath of aqueous nitrous acid. When the original color has disappeared, the goods are placed in an alkaline bath of sodium naphthol. The coupling ended after a few moves. The coloration achieved is a washable blue, while the original coloration was a washable violet.
With similarly composed dyes, which primarily contain other components, it is not possible, even after development with ss-naphtol, to achieve dyeings which have similar washfastness with the same good lightfastness.
