Description
Verfahren zur Herstellung einer Farbstoffmischung. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung einer Farbstoff mischung, dadurch gekennzeichnet, da.ss man den Farbstoff, hergestellt gemäss Schweizer Patent Nr.
1-81166 durch Einführung von 2 Chloratomen in,das Benzoylierungsprodukt des alkalischen Kondensationsproduktes von Bz, -Benzanthronyl-1-amino-5-aminoa.nthra- ehinon. mit dem blauen Farbstoff der Di- benzanthronreihe mischt, der durch Einwir kung von Brom auf Dibenzanthron in Gegen wart von Chlonsulfonsäure erhalten wird.
Mit dieser Mischung erhält man auf Baum wolle eine kräftige, grünstichige Schwarz färbung.
<I>Beispiel:</I> 4,2 Teile des Farbstoffes, hergestellt nach Schweizer Patent Nr. 181166, werden mit 3,6 Teilen des blauen Farbstoffes der Dibenz- a.nthronreihe bemisaht, hergestellt,durch Ein- wirkung von Brom auf Dibenzanthron in Gegenwart von Chlorsulfonsäure.
Process for the preparation of a dye mixture. The present patent relates to a method for producing a dye mixture, characterized in that the dye, produced according to Swiss patent no.
1-81166 by introducing 2 chlorine atoms into the benzoylation product of the alkaline condensation product of Bz, -Benzanthronyl-1-amino-5-aminoa.nthra- ehinon. Mixes with the blue dye of the dibenzanthrone series, which is obtained by the action of bromine on dibenzanthrone in the presence of chlorosulfonic acid.
This mixture gives cotton a strong, greenish black color.
<I> Example: </I> 4.2 parts of the dye, produced according to Swiss Patent No. 181166, are covered with 3.6 parts of the blue dye of the Dibenz-a.nthron series, produced by the action of bromine Dibenzanthrone in the presence of chlorosulfonic acid.
