  <B>Zusatzpatent</B> zum Hauptpatent Nr. 202856.    Verfahren zur Herstellung eines neuen, metallhaltigen     Beizenfarbstoffes.       Es     wurde        :gefunden,    dass man     einen,    neuen,       chromhaltigen        Beizenfarbstoff    erhält,

   wenn  man ein Molekül     2-Amino-5-oxynaphthalin-7-          sulfonsäure    zuerst in schwach     saurem    Medium       mit    einem Molekül     diazotierter        4-Amino-l-          oxybenzol    - -6 -     carbonsäure    und nachher in  schwach alkalischem Medium mit einem  Molekül     diazotierter        1-Oxy-2-amino-6-nitro-          benzol-4-sulfonsäure    kuppelt und ,

  den erhal  tenen     Disazofarbstoff    mit einer     c11romabge-          benden    Substanz     behandelt.     



  <I>Beispiel:</I>  15,3 Teile     4-Amino-l-oxybenzol-6-carbon-          säuTe    werden wie üblich     diazotiert    und in  essigsaurer Lösung auf     23,9    Teile     2-Amino-          5    -     oxynaphthalin    - 7 -     sulf        onsäure    gekuppelt.

    Dann wird der erhaltene     Monoazofarbstoff    in       alkalischer    Lösung mit der     Diazoverbindung     aus 23,4 Teilen     1-Oxy-2-amino-6-nitrobenzol-          4-sulfonsäure        weitergekuppelt.        Nach    beende  ter Kupplung wird der erhaltene     Disazofarb-          stoff        Hausgesalzen,        abgerutscht,    in 2000 Tei-         len    kochendem     Wasser    gelöst und die Lö  sung unter Zusatz einer     Chromacetatlösung     entsprechend 30,

  4 Teilen     Cr203    während 15       Stunden    unter     Rückfluss    ,gekocht. Die neue       Chromverbindung    wird durch Eindampfen  der Lösung in fester Form     gewonnen.     



  Der neue,     chromhaltige    Farbstoff bildet,  wenn getrocknet, ein , dunkles Pulver, löst  sich     in,    Wasser mit blaugrauer, in     konzen-          trierter        Schwefelsäure    mit     violetter    Farbe  und liefert im Chromdruck     auf    Baumwolle,       Kunstseide    aus regenerierter Zellulose oder  auf Naturseide tiefe,     grünstichig        graue    Töne,  die sich durch gute     Echtheiten    auszeichnen.



  <B> Additional patent </B> to main patent no. 202856. Process for the production of a new, metal-containing stain dye. It was found that a, new, chromium-containing stain dye is obtained,

   if one molecule of 2-amino-5-oxynaphthalene-7-sulfonic acid is first mixed in a weakly acidic medium with a molecule of diazotized 4-amino-l-oxybenzene - -6 - carboxylic acid and then in a weakly alkaline medium with a molecule of diazotized 1-oxy- 2-amino-6-nitrobenzene-4-sulfonic acid couples and,

  the disazo dye obtained is treated with a chromium-releasing substance.



  <I> Example: </I> 15.3 parts of 4-amino-1-oxybenzene-6-carbon acids are diazotized as usual and in acetic acid solution to 23.9 parts of 2-amino-5-oxynaphthalene-7-sulf on acid coupled.

    The monoazo dye obtained is then coupled in an alkaline solution with the diazo compound from 23.4 parts of 1-oxy-2-amino-6-nitrobenzene-4-sulfonic acid. After the coupling is complete, the disazo dye obtained is house salts, slipped off, dissolved in 2000 parts of boiling water and the solution is dissolved with the addition of a chromium acetate solution corresponding to 30,

  4 parts of Cr203 refluxed for 15 hours, boiled. The new chromium compound is obtained in solid form by evaporating the solution.



  When dried, the new chromium-containing dye forms a dark powder, dissolves in water with a blue-gray color, in concentrated sulfuric acid with a violet color and, when printed with chrome, produces deep, green-tinged gray tones on cotton, artificial silk made from regenerated cellulose or natural silk , which are characterized by good fastness properties.
