  Zusatzpatent zum Hauptpatent     Nr.    -212415.    Verfahren zur Herstellung eines neuen     Beizenfarbstoffes.       Es wurde gefunden,     dass    man zu einem  neuen     Beizenfarbstoff    gelangt, wenn man  <B>1</B>     Mol.        2-Amino-5-naplitol-7-sulfosäure    mit  <B>1</B>     Mol.        diazotierter        1-Oxy-2-aminobenzol-4-          sulfosäure    alkalisch kuppelt,

   den erhaltenen       Monoazofarbstoff    weiter     diazotiert    und mit  der alkalischen Lösung von     1-(4'-Oxybenzol-          l'-sulfoyla,miiio)   <B>- 8 -</B>     oxynaphtalin-6-sulfosäure-          3'-carbonsäure    kombiniert.  



  Der erhaltene     Disazofarbstoff    kann vorteil  haft mit einer     ehromabgebenden    Substanz  behandelt werden, um als     ehromhaltiger    Farb  stoff verwendet zu werden.    <I>Beispiel:</I>    <B>189</B> Teile     1-Oxy-2-a-rninobenzol-4-sulfo-          säure    werden wie üblich     diazotiert    und in  alkalischer Lösung mit<B>239</B> Teilen     2-Amino-          5-iiaphtol,-7-sulfosäure    vereinigt.

   Der gebildete       Monoazofarbstoff    wird weiter     diazotiert    und  mit einer alkalischen Lösung von 439 Teilen  <B>1 -</B>     (4'-        Oxybenzol-        l'-sulfoylamino)-   <B>8</B> -oxynaph-         talin-   <B>6</B>     -sulfosäure-        3'-carbonsäure    kombiniert.  Nach beendeter Kupplung wird der erhaltene       Disazofarbstoff    in üblicher Weise durch     Aus-          salzen    abgeschieden.  



  Der neue, so erhaltene Farbstoff bildet       ein    dunkles Pulver, das sich in Wasser mit       rotsticliigblauer    Farbe und in konzentrierter  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 mordant dye. It has been found that a new mordant dye is obtained if 1 mole of 2-amino-5-naplitol-7-sulfonic acid is mixed with 1 mole of diazotized 1-oxy -2-aminobenzene-4-sulfonic acid alkaline coupling,

   the monoazo dye obtained is further diazotized and combined with the alkaline solution of 1- (4'-oxybenzene-l'-sulfoyla, miiio) - 8 - oxynaphthalene-6-sulfonic acid-3'-carboxylic acid.



  The disazo dye obtained can advantageously be treated with an Ehrom-donating substance to be used as an Ehrom-containing dye. <I> Example: </I> <B> 189 </B> parts of 1-oxy-2-α-rninobenzene-4-sulfonic acid are diazotized as usual and in an alkaline solution with <B> 239 </B> Parts of 2-amino-5-iiaphtol, -7-sulfonic acid combined.

   The monoazo dye formed is further diazotized and treated with an alkaline solution of 439 parts 1 - (4'-oxybenzene-1'-sulfoylamino) - 8 -oxynaphthalene- <B > 6 </B> -sulfonic acid- 3'-carboxylic acid combined. After the coupling has ended, the disazo dye obtained is deposited in the customary manner by salting out.



  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. In chrome print on cotton, it delivers blue tones that are characterized by good fastness properties.
