Description
Verfahren zur Herstellung eines direktziehenden o-Osyazofarbstoffes. Es wurde gefunden, dass durch Kuppeln von diaz.otiertem 2-Aniino-4-clilor-l-oxyberi- zol mit dem Harnstoffe der 2-Amino-5-oxy- naphtalin-7-sulfosäure ein direktziehender o-Oxyazofarbstoff erhalten wird, welcher Baumwolle in licht- und alkaliempfind- lichen, gelbrosa Tönen anfärbt.
Durch Nach kupfern oder noch besser durch Färben in der für direktziehende Farbstoffe üblichen Weise unter Zusatz von Kupferverbindun- gen zum Bade werden hervorragend liclit- und alkaliechte blaurote Töne erhalten.
<I>Beispiel:</I> 28,7 kg 2-Amirio-4-chlor-l-oxyberizol wer den in die Diazoverbindung übergeführt und diese in eine Lösung von 50,4 kg Harnstoff der 2-Amino-5-oxynaphtalin-7-sulfosäure und 50 kg Soda einfliessen gelassen. Nach 12 Stunden wird der Farbstoff a-usgesalzen, fil triert und getrocknet.
Process for the production of a substantive o-osyazo dye. It has been found that by coupling diaz.otosed 2-aniino-4-clilor-1-oxyberizole with the urea of 2-amino-5-oxynaphthalene-7-sulfonic acid, a substantive o-oxyazo dye is obtained, which Dyes cotton in light- and alkali-sensitive, yellow-pink tones.
After coppering or, even better, coloring in the manner customary for substantive dyes with the addition of copper compounds to the bath, excellent licit- and alkali-fast blue-red tones are obtained.
<I> Example: </I> 28.7 kg of 2-amirio-4-chloro-l-oxyberizole are converted into the diazo compound and this is converted into a solution of 50.4 kg of urea of the 2-amino-5-oxynaphthalene- 7-sulfonic acid and 50 kg of soda are allowed to flow in. After 12 hours, the dye is salted out, filtered and dried.
