Description

  

  Verfahren zur Herstellung eines neuen, metallhaltigen     Beizenfarbstofes.       Es wurde gefunden, dass man einen neuen,  chromhaltigen     Beizenfarbstoff    erhält, wenn  man ein Molekül     2-Amino-5-oxynaphthaliri-7-          sulfonsäure    zuerst in schwach saurem Medium  mit einem Molekül dianotierter     2-Amino-l-          oxybenzol-6-carbonsäure    und nachher in  schwach alkalischem Medium mit einem Mole  kül dianotierter     1-Oxy-2-amino-6-nitrobenzol-          4-sulfonsäure    kuppelt und den erhaltenen       Disazofarbatoff    mit einer chromabgebenden  Substanz behandelt.  



  <I>Beispiel:</I>  15,3 Teile     2-Amino-l-oxybenzol-6-carbon-          säure    werden wie üblich dianotiert und in  essigsaurer Lösung auf 23,9 Teile     2-Amino-          5-oxynaphthalin-7-sulfonsäuregekuppelt.    Dann  wird der erhaltene     Monoazofarbstoff    in alka  lischer Lösung mit der     Diazoverbindung    aus  23,4 Teilen     1-Oxy-2-amino-6-nitrobenzol-4-          sulfonsäure    weitergekuppelt.

   Nach beendeter  Kupplung wird der erhaltene     Disazofarbstoff          ausgesalzen,        abgenutscht,    in 2000 Teilen    kochendem Wasser gelöst und die Lösung  unter Zusatz von 80 Teilen Ameisensäure  und einer     Ohromformiatlösung    entsprechend  30,4 Teilen     Crs03    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 graues Pulver, löst sich  in Wasser mit graublauer, in konzentrierter  Schwefelsäure mit violetter Farbe und liefert  im Chromdruck auf Baumwolle, Kunstseide  aus regenerierter     Cellulose    oder auf Natur  seide graublaue Töne, die sich durch gute       Echtheiten    auszeichnen.



  Process for the production of a new, metal-containing stain dye. It has been found that a new, chromium-containing mordant dye is obtained if one molecule of 2-amino-5-oxynaphthalene-7-sulfonic acid is first mixed with a molecule of dianotized 2-amino-l-oxybenzene-6-carboxylic acid in a weakly acidic medium and then coupling in a weakly alkaline medium with a mole of kül dianotized 1-oxy-2-amino-6-nitrobenzene-4-sulfonic acid and treated the disazo carbate obtained with a chromium-releasing substance.



  <I> Example: </I> 15.3 parts of 2-amino-1-oxybenzene-6-carboxylic acid are dianotized as usual and coupled to 23.9 parts of 2-amino-5-oxynaphthalene-7-sulfonic acid in acetic acid solution . The monoazo dye obtained is then coupled further in alkali solution with the diazo compound from 23.4 parts of 1-oxy-2-amino-6-nitrobenzene-4-sulfonic acid.

   When the coupling is complete, the disazo dye obtained is salted out, suction filtered, dissolved in 2000 parts of boiling water and the solution is refluxed for 15 hours with the addition of 80 parts of formic acid and an odor formate solution corresponding to 30.4 parts of Crs03. The new chromium compound is obtained in solid form by evaporating the solution.



  The new chromium-containing dye forms a gray powder when dried, dissolves in water with a gray-blue color, in concentrated sulfuric acid with a violet color and, when printed with chrome on cotton, rayon made from regenerated cellulose or on natural silk, it produces gray-blue tones that are characterized by good fastness properties .
