oder seiner Substitutionsprodukte mit Kupplungskomponenten, die keine löslich machenden Gruppen enthalten, wertvolle wasserunlösliche Azofarbstoffe erhält. Die auf der Faser hergestellten Farbstoffe zeichnen sich neben guter Chlor- und Kochechtheit durch gedeckte, volle Nuancen aus.or its substitution products with coupling components that are not solubilizing Contain groups that contain valuable water-insoluble azo dyes. The dyes produced on the fiber stand out in addition to good chlorine and boiling fastness through muted, full nuances.

50 g Baumwollgarn werden in 11 einer mit 2 g ι - (2' · 3'- Oxynaphthoylamino) - 3 - nitrobenzol auf übliche Weise hergestellten Lösung 1J2 Stunde bei 300C grundiert und gut ausgewunden. Nach dem Entwickeln mit einer durch Natriumacetat abgestumpften Lösung, die 2,45 g diazotiertes Bz-i-Aminobenzanthron im Liter enthält, wird gespült und kochend geseift. Man erhält ein blaustichiges Schwarzviolett von guten Echtheitseigenschaften.50 g of cotton are a 2 g ι in 11 - (2 'x 3' oxynaphthoylamino) - 3 - nitrobenzene primed in a usual manner prepared solution 1 J 2 hour at 30 0 C and well-wrung. After developing with a solution blunted by sodium acetate, which contains 2.45 g of diazotized Bz-i-aminobenzanthrone per liter, it is rinsed and soaped at the boil. A bluish black violet with good fastness properties is obtained.
6 g 2 · 3-Oxynaphthoylaminobenzol werden wie in Beispiel 1 gelöst. Behandelt man das mit dieser Lösung grundierte Baumwollgarn mit einer Lösung, die 2,75 g diazotiertes Bz-i-Amino-2-methoxybenzanthron im Liter enthält, so bekommt man nach dem Seifen ein grünstichiges Blau von hervorragender Chlorechtheit. 6 g of 2x3-oxynaphthoylaminobenzene will be as solved in example 1. Treat the cotton yarn primed with this solution with a solution containing 2.75 g of diazotized Bz-i-amino-2-methoxybenzanthrone per liter contains, you get a greenish blue with excellent chlorine fastness after soaping.
3 g ι - (2' · 3 '-Oxynaphthoylamino) -2-methyl-4-methoxybenzol werden in der üblichen Weise gelöst und die Lösung auf 1 1 gestellt. 50 g Baumwollgarn werden in dieser Lösung bei 300C grundiert. Nach dem Entwickeln in einer Lösung, die 2,75 g diazotiertes Bz-i-Amino-2-methoxybenzanthron im Liter enthält, wird kochend geseift. Man bekommt ein klares rotstichiges Blau von hervorragender Koch- und Chlorechtheit.3 g of ι - (2 '· 3' -oxynaphthoylamino) -2-methyl-4-methoxybenzene are dissolved in the usual manner and the solution is made up to 1 liter. 50 g of cotton yarn are primed at 30 ° C. in this solution. After developing in a solution containing 2.75 g of diazotized Bz-i-amino-2-methoxybenzanthrone per liter, soapy is carried out at the boil. You get a clear, reddish blue with excellent boiling and chlorine fastness.
2 g i- (2' · 3'-Oxynaphthoylamino) -2-methoxy^-methoxy-S-cnlorbenzol werden wie in Beispiel 1 gelöst.

enthält, so bekommt man nach dem Seifen ein Marineblau von sehr guten Echtheitseigenschaften. contains, a navy blue with very good fastness properties is obtained after soaping.
o,6 g i-(2'-Oxyanthracen-3'-cafboylamino)-2-methylbenzol werden auf die übliche Weise zum Liter gelöst. 50 g Baumwollgarn werden mit dieser Lösung grundiert, abgequetscht, und die Färbung wird mit einer Lösung, die 2,75 S diazotiertes Bz-i-Amino-2-methoxybenzanthron im Liter enthält, entwickelt. Dann wird gespült und geseift. Man erhält ein gelbstichiges Grün von guter Chlorechtheit.0.6 g of i- (2'-oxyanthracene-3'-cafboylamino) -2-methylbenzene are dissolved in the usual way to the liter. 50 g of cotton yarn are primed with this solution, squeezed off, and the color is developed with a solution containing 2.75 S diazotized Bz-i-amino-2-methoxybenzanthrone per liter. Then it is rinsed and soaped. A yellowish green of good fastness to chlorine is obtained.
