Description

  

      Zusatzpatent    zum Hauptpatent Nr. 163542.         Verfahren    zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhalten kann, wenn       man    den     Azofarbstoff    aus dianotierter     4-Sulfo-          2-aminobenzol-l-karbonsäure    und     1-(2'-Chlor-)-          phenyl-3-methyl-5-pyrazolon    mit chromabge  benden Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkelgelbes Pulver dar, das sich in  Wasser mit gelber Farbe löst und Wolle aus  saurem Bade in     rötlichgelben    Tönen färbt,  die sich durch eine hervorragende Lichtecht  heit auszeichnen.  



  <I>Beispiel:</I>  Eine Lösung von<B>21,6</B> Teilen des     Azo-          farbstoffes    aus dianotierter     4-Sulfo-2-amino-          benzc,1-1-karbonsäur#e    und     1-(2'-Chlor-)phenyl-          3-rnethyl-5-pyrazolon    in 400 Teilen Wasser  wird nach Zugabe einer Lösung von     Chrom-          fluorid,    enthaltend 4,6 Teile     Chromoxyd,    etwa    1\? Stunden unter     Rückfluss    gekocht. Die  Chromverbindung wird mit Kochsalz abge  schieden und getrocknet.



      Additional patent to main patent No. 163542. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye can be obtained if the azo dye is obtained from dianotated 4-sulfo-2-aminobenzene-1-carboxylic acid and 1- (2'-chloro -) - phenyl-3-methyl-5-pyrazolone treated with chromium-releasing agents.



  The metal-containing dye obtained is a dark yellow powder which dissolves in water with a yellow color and dyes wool from an acid bath in reddish-yellow tones, which are characterized by excellent lightfastness.



  <I> Example: </I> A solution of <B> 21.6 </B> parts of the azo dye from dianotated 4-sulfo-2-aminobenzc, 1-1-carboxylic acid and 1- ( 2'-chloro) phenyl-3-methyl-5-pyrazolone in 400 parts of water, after adding a solution of chromium fluoride containing 4.6 parts of chromium oxide, about 1 \? Boiled under reflux for hours. The chromium compound is separated out with common salt and dried.
