      Zusatzpatent    zum     Hauptpatent    Nr. 147796.    Verfahren zur Herstellung eines     chromhaltigen        Farbstoffes.       Es wurde     gefunden,    dass man .einen echt  blau färbenden, in Wasser leicht löslichen       chromhaltigen.    Farbstoff, der aus schwach  sauren     Farbbädern    auf die Faser aufzieht  und durch Verstärken der     Acidität    des  Färbebades auf der Faser entwickelt werden  kann, erhält,

   wenn man den Farbstoff aus  der     Diazoverbindung    der     1-Amino-2-oxy-          naphthalin-4-sulfosäure    und     ss-Naphthol    in  Gegenwart solcher     Mengen        Alkalimetall-          ionen,    die weder     aussalzend    auf den Farb  stoff wirken noch dessen     färberische    Eigen  schaften     ungünstig    beeinflussen, derart mit       chromabgebenden    Mitteln behandelt, dass auf  jede     ehromierbaxe    Gruppe des     Farbstoffmole-          küls    mindestens ,

  ein Atom Chrom     eintritt.     



  Der erhaltene Farbstoff färbt Wolle in  echten blauen Tönen und eignet sich auch  zum Bedrucken von     Viskos-e    in     Gegenwart     von Chrombeizen.  



  <I>Beispiel:</I>  41,7 Teile des     Natronsalzes    des Farb  stoffes aus     diazotierter    1-Amino-2-oxynaph-         thalin-4-sulfosäure    und     (3-Naphtliol    werden  in 1500 Teilen siedendem Wasser gelöst und  mit 66 Teilen einer     14%igen        Chromoxa1at-          lösung,    enthaltend 9,2 Teile     CrA;,,    so     langi@     gekocht, bis eine herausgenommene Probe  zeigt, dass der entstandene     Komplex    die     Llr-          forderliohen    Eigenschaften zeigt.

   Nach Küh  len auf<B>50'</B>     wird    die erhaltene     Suspension     der Chromverbindung durch     Zuceben    von  10%iger Natronlauge gelöst und gleich her  nach mit einer der verbrauchten Natronlauge  äquivalenten Menge Essigsäure neutral     o-e-          stellt    und der Farbstoff durch     Aussülzen    ab  geschieden.  



       7u    einem sich     färberisch    gleichverhal  tenden, Farbstoffe gelangt man auch, wenn  man statt mit dem im Beispiel erwähnten  Mittel die     Chromierung    mit andern     Mitteln     durchführt, so zum Beispiel mit     Fluorchrom     und     Natrium,sulfit;    Chromacetat und Na  triumacetat;

   Chromsulfat,     Natriumbisulrit     und     Natriumacetat;        Fluorcbrom,        Chromoxa-          lat    und     Natriumoxa.lat;        Fluorchrom,    Chrom-           formiat    und     Natriumformiat;        Chromoxalat     und     Natriumacetat;    Chromsulfat und     Alkali-          sa.lze    organischer     Sulfo"äuren;    Chromsalze       orga.nisclier        Sulfosäuren    und Natriumsulfat.



      Additional patent to main patent No. 147796. Process for the production of a chromium-containing dye. It has been found that a chromium-containing chromium which is really blue in color and is readily soluble in water can be found. Dye which is absorbed onto the fiber from weakly acidic dye baths and which can be developed on the fiber by increasing the acidity of the dye bath,

   if you take the dye from the diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid and ss-naphthol in the presence of such amounts of alkali metal ions that neither act salting out on the dye nor affect its coloring properties unfavorably, such treated with chromium-releasing agents that for each Ehromierbaxe group of the dye molecule at least,

  an atom of chromium enters.



  The dye obtained dyes wool in real blue tones and is also suitable for printing viscose in the presence of chrome stains.



  <I> Example: </I> 41.7 parts of the sodium salt of the dye from diazotized 1-amino-2-oxynaphthalene-4-sulfonic acid and (3-naphthiol are dissolved in 1500 parts of boiling water and 66 parts of a 14% chromium oxalate solution containing 9.2 parts of CrA; boiled until a sample taken out shows that the complex formed shows the required properties.

   After cooling to <B> 50 '</B>, the resulting suspension of the chromium compound is dissolved by adding 10% sodium hydroxide solution and immediately made neutral with an amount of acetic acid equivalent to the used sodium hydroxide solution, and the dye is separated off by purging .



       Dyes can also be obtained with the same behavior in terms of color if, instead of using the agent mentioned in the example, the chromating is carried out with other agents, for example with fluorochrome and sodium sulfite; Chromium acetate and sodium acetate;

   Chromium sulfate, sodium bisulrite and sodium acetate; Fluorocbromine, chromium oxalate and sodium oxalate; Fluorochrome, chromium formate and sodium formate; Chromium oxalate and sodium acetate; Chromium sulphate and alkali salts of organic sulphonic acids; chromium salts of organic sulphonic acids and sodium sulphate.
