      Zusatzpatent    zum Hauptpatent Nr. 212415.    Verfahren zur Herstellung eines neuen     Beizenfarbstoffes.       Es wurde gefunden, dass man zu einem  neuen     Beizenf        arbstof    f gelangt, wenn man 1     Mol.     2     -Amino    - 5     -naphtol-1    :

   7 -     disu,lfosäure    mit 1       Mol.        diazotierter        1-Oxy-2-amino-6-chlorbenzol-          4-sulfosäure    alkalisch kuppelt, den erhaltenen       Monoazofarbstoff    weiter     diazotiert    und mit  der alkalischen Lösung von     1-(4'-Oxybenzol-          1'-sulf        oylamino)-8-oxynaphtalin-3    :     6-disulf        o-          säure-3'-carbonsäure    kombiniert.  



  Der erhaltene     Disazofarbstoff    kann vor  teilhaft mit einer chromabgebenden Substanz  behandelt werden, um als chromhaltiger Farb  stoff verwendet zu werden.  



       Beispiel:     223 Teile     1-Oxy-2-amino-6-chlorbenzol-4-          sulfosäure    werden wie üblich     diazotiert    und  in alkalischer Lösung mit 319 Teilen     2-          Amino-5-naphtol-1        :7-disulfosäure    vereinigt.  Der gebildete     Monoazofarbstoff    wird weiter       diazotiert    und mit einer alkalischen Lösung  von 519 Teilen     1-(4'-Oxybenzol-1'-sulfoyl-          amino)-8-oxynaphtalin-3    : 6- disulfosäure-3'-         carbonsäure    kombiniert.

   Nach beendeter       Kupplung    wird der erhaltene     Disazofarbstoff     in üblicher Weise durch     Aussalzen    abgeschie  den.  



  Der neue, so erhaltene Farbstoff bildet  ein dunkles Pulver, das sich in Wasser mit       blaustichigvioletter    Farbe und in konzentrier  ter Schwefelsäure mit     grünstichigblauer     Farbe löst. Im Chromdruck auf Baumwolle  liefert er blaue Töne, die sich durch gute       Echtheiten    auszeichnen.



      Additional patent to main patent No. 212415. Process for the production of a new stain dye. It has been found that a new stain dyestuff is obtained if 1 mol. 2-amino-5-naphthol-1 is added:

   7 - disu, lfoic acid with 1 mol. Of diazotized 1-oxy-2-amino-6-chlorobenzene-4-sulfonic acid, the resulting monoazo dye is further diazotized and with the alkaline solution of 1- (4'-oxybenzene-1'- sulfoylamino) -8-oxynaphthalene-3: 6-disulfoic acid-3'-carboxylic acid combined.



  The disazo dye obtained can be treated before geous with a chromium-releasing substance to be used as a chromium-containing dye.



       Example: 223 parts of 1-oxy-2-amino-6-chlorobenzene-4-sulfonic acid are diazotized as usual and combined with 319 parts of 2-amino-5-naphthol-1: 7-disulfonic acid in an alkaline solution. The monoazo dye formed is further diazotized and combined with an alkaline solution of 519 parts of 1- (4'-oxybenzene-1'-sulfoylamino) -8-oxynaphthalene-3: 6-disulfonic acid-3'-carboxylic acid.

   After coupling has ended, the disazo dye obtained is deposited in the customary manner by salting out the.



  The new dye obtained in this way forms a dark powder which dissolves in water with a bluish violet color and in concentrated sulfuric acid with a greenish blue color. In chrome print on cotton, it delivers blue tones that are characterized by good fastness properties.
