Description

  

  Verfahren zur Herstellung eines neuen     Beizenfarbstofes.       Es wurde gefunden, dass man zu einem  neuen     Beizenfarbstoff    gelangt, wenn man  1     Mol.        2-Amino-        "5        -naphtol-    7     -sulfosäure    mit  1     Mol.    dianotierter     1-Oxy-    2     -aminobenzol-4-          sulfosäure        alkalisch    kuppelt,

   den erhaltenen       Monoazofarbstoff    weiter dianotiert und mit  der alkalischen Lösung von     1-(4'-Oxybenzol-          1'-        sulfoylamino)    - 8     -oxynaphtalin-3    :     6-disulfo-          säure-3'-carbonsäure    kombiniert.  



  Der erhaltene     Disazofarbstoff    kann vor  teilhaft mit einer chromabgebenden Substanz  behandelt werden, um als chromhaltiger  Farbstoff verwendet zu werden.         Beispiel:       189 Teile     1-Oxy-2-aminobenzol-4-sulfo-          säure    werden wie üblich dianotiert und in  alkalischer Lösung mit 239     Teilen        2-Amino-          5-naphtol-7-sulfosäure    vereinigt.

   Der gebildete       Monoazofarbstoff        wird    weiter dianotiert und  mit einer     alkalischen    Lösung von 519 Teilen  1- (4 '-     Oxybenzol-1'-        sulfoylamino)-    8-oxynaph-         talin-3    :     6-disulfosäure    - 3'-     carbonsäure    kombi  niert. Nach beendeter     Kupplung        wird    der  erhaltene     Disazofarbstoff    in     üblicher    Weise  durch Aussahen abgeschieden.  



  Der neue, so erhaltene     Farbstoff    bildet  ein dunkles Pulver, das sich     in    Wasser mit       rotstichigblauer    Farbe und     in        konzentrierter     Schwefelsäure mit     grünstichigblauer    Farbe  löst. Im Chromdruck auf Baumwolle liefert:  er blaue Töne, die sich durch gute     Echt-          heiten    auszeichnen.



  Process for the production of a new stain dye. It has been found that a new mordant dye is obtained if 1 mole of 2-amino- "5-naphthol-7-sulfonic acid is coupled alkaline with 1 mole of dianotated 1-oxy-2-aminobenzene-4-sulfonic acid,

   the monoazo dye obtained is further dianotized and combined with the alkaline solution of 1- (4'-oxybenzene-1'-sulfoylamino) -8-oxynaphthalene-3: 6-disulfonic acid-3'-carboxylic acid.



  The disazo dye obtained can be treated with a chromium-releasing substance before geous in order to be used as a chromium-containing dye. Example: 189 parts of 1-oxy-2-aminobenzene-4-sulfonic acid are dianotized as usual and combined with 239 parts of 2-amino-5-naphthol-7-sulfonic acid in an alkaline solution.

   The monoazo dye formed is further dianotized 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 the coupling has ended, the disazo dye obtained is deposited in the customary manner by looking.



  The new dye obtained in this way forms a dark powder which dissolves in water with a reddish blue color and in concentrated sulfuric acid with a greenish blue color. With chrome printing on cotton: it delivers blue tones that are characterized by good authenticity.
