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.
