Description

Verfahren zur Darstellung von Monoazofarbstoffen. In dem Hauptpatent wurde gezeigt, daß durch Einwirkung von diazotierten m-Amino-1 unzaldehyden auf Pyrazolone wertvolle echlu gelbe saure Wollfarbstoffe entstehen.Process for the preparation of monoazo dyes. In the main patent it was shown that by the action of diazotized m-amino-1 unzaldehydes on Pyrazolone valuable echlu yellow acidic wool dyes are formed.

Es wurde weiter gefunden, daß durch E, inivirkung dieser Diazoverbindungen auf :ii der Aminogruppe alkylierte oder arylierte Derivate der 2-Arniiio-S-iiaplithol-6-sulfosätire neue bis rotbratin färbende saure Wollfarbstoffe entstehen, die bei gutem Egalisieren und guter Alkali- und Lichtechtheit eine überraschend gute Wasch- und Mi'asserechtheit besitzen.It was further found that by E, this diazo inivirkung on alkylated ii the amino group or arylated derivatives of 2-Arniiio-S-iiaplithol-6-sulfosätire new ones to rotbratin coloring acid wool dyes with good leveling and good alkali and Lightfastness have surprisingly good washfastness and waterfastness.

12,1 kg ni-Aininobeiizaldehy,1 wei-Jen in bekannter Weise diazotiert und init (ler sodaalkalischen Lösung von V,5 k- 2-Phen#I-aiiiiiie-8-iiaphtlic)l-6-stilfosäure wie üblich gekuppelt. Der ausgesalzene Farbstoff egalisiert gut und färbt Wolle aus saurem Bade in lebhaft rotbraunen echten Tönen an. Er eignet sich auch zum Wolldruck.12.1 kg of ni-Aininobeiizaldehy, 1 Wei-Jen diazotized in a known manner and coupled with (ler soda-alkaline solution of V, 5 k- 2-phen # I-aiiiiiie-8-iiaphtlic) l-6-stilfosäure as usual. The salted-out dye levels out well and dyes wool from an acid bath in vivid red-brown real tones. It is also suitable for wool printing.
