Verfahren zur Darstellung eines Disazofarbstoffes.Process for the preparation of a disazo dye.
Patentiert im Deutschen Reiche vom 11. August 1910 ab.Patented in the German Empire on August 11, 1910.
Es wurde gefunden, daß der Farbstoff aus der Tetrazoverbindung der ρ · p'-Diaminodiphenylharnstoff-m ■ m'-disulfosäure des Patents 140613 mit 2 Molekülen m-Phenylendiamin vorzüglich geeignet ist, auf der Faser durch Nachbehandlung mit diazotiertem p-Nitranilin ein weiß ätzbares, waschechtes, sehr gut lichtechtes Rotbraun zu liefern, das sich vor den mit den Farbstoffen des Patents 216685 erhältlichen, auf der Faser entwickelten Färbungen durch größere Vertiefung der Nuance und erhöhte Lichtechtheit auszeichnet. Bei der bekannten Lichtunechtheit der Chrysoidine war dieses Verhalten in keiner Weise vorauszusehen.It has been found that the dye from the tetrazo compound of the ρ · p'-diaminodiphenylurea-m ■ m'-disulfonic acid of patent 140613 with 2 molecules of m-phenylenediamine is eminently suitable for post-treatment on the fiber to deliver a white, etchable, washable, very lightfast reddish brown with diazotized p-nitroaniline, which is in front of the Dyes of patent 216685 available, developed on the fiber by larger dyeings Deepening of the nuance and increased lightfastness. With the well-known light infastness of the Chrysoidine, this behavior was in no way predictable.
Beispiel. 402 Teile der Tetrazoverbindung aus der ρ · p'-Diaminodiphenylharnstoff-m · m'-disulfosäure des Patents 140613 werden in schwach alkalischer Lösung mit 216 Teilen m-Phenylendiamin zum Farbstoff gekuppelt; derselbe gibt auf Baumwolle direkt ein Gelbbraun, bei Nachbehandlung mit diazotiertem p-Nitranilin ein sehr schönes volles Rotbraun von güter Waschechtheit, Ätzbarkeit und großer Lichtechtheit.Example. 402 parts of the tetrazo compound from the ρ · p'-diaminodiphenylurea-m · m'-disulfonic acid of the patent 140613 are in weakly alkaline solution with 216 parts of m-phenylenediamine coupled to the dye; the same gives a yellow-brown directly on cotton, after treatment with diazotized p-nitroaniline a very beautiful full reddish brown of good washfastness, etchability and great lightfastness.
