Description

  

  Verfahren zur Herstellung eines neuen, metallhaltigen     Beizenfarbstoffes.       Im Patentanspruch des Hauptpatentes ist  ein Verfahren zur Herstellung eines neuen,  kupferhaltigen     Beizenfarbstoffes    gekenn  zeichnet, gemäss welchem man     diazotierte     1-     Ogy-    2     -amino    -4 -     chlorbenzol-    6     -sulfonsäure     auf das Kondensationsprodukt aus     Salicyl-          e,äuresu@lfoehloricl        und    1 .

   8 -     Aminonaphtol-          3.        6-disulfosäure    kuppelt und den erhaltenen       Monoazofarbstoff    mit einer kupferabgeben  den Substanz behandelt.  



  Gemäss dem vorliegenden Zusatzpatent er  hält man einen ähnlichen neuen Farbstoff,  wenn man im Verfahren des Hauptpatentes  die 1' . 8 -     Ani.nonaphtol    - 3 . 6 -     diGulfosänre          .durch    die 1 . 8 -     Aminonaphtol    - 4. 6 -     disulfo-          säure    ersetzt.

      <I>Beispiel:</I>    22,5 Teile 1-     Ogy    -2-     amino    -4-     chlorbenzol-          6-sulfosäure    werden wie üblich     diazotiert    und  die     Diazolösung    mit einer alkalischen Lösung  von 51,9 Teilen des Kondensationsproduktes  aus     Salicylsäuresulfochlorid    und 1 . 8-Amino-         naphtol    - 4 .

   6 -     disulfosäure        gekuppelt.    Der  entstandene     Monoazofarbstoff    wird mit der  wässerigen     Lösung    von 25 Teilen kristalli  siertem Kupfersulfat während 1     Stunde    auf  90   C erhitzt und die Kupferverbindung  durch     Aussalzen    isoliert. Durch Kochen einer  Lösung der Kupferverbindung bei Gegen  wart von Alkali kann,     wenn    nötig, nicht  komplexgebundenes Kupfer gefällt werden.  



  Der neue kupferhaltige Farbstoff bildet,  wenn getrocknet, ein violettes Pulver, löst  sich     in    Wasser mit rotvioletter, in verdünn  ter Natronlauge mit blauvioletter Farbe     und     liefert im Chromdruck auf Baumwolle,       Kunstseide    aus regenerierter     Cellulose    oder  auf Naturseide lebhafte, rotviolette Töne, die  sich durch gute     Echtheiten,    insbesondere  durch eine gute Lichtechtheit, auszeichnen.



  Process for the production of a new, metal-containing stain dye. In the claim of the main patent, a process for the production of a new, copper-containing mordant dye is marked, according to which diazotized 1- Ogy- 2 -amino -4-chlorobenzene- 6-sulfonic acid on the condensation product of salicyl e, äuresu @ lfoehloricl and 1.

   8 - aminonaphthol- 3. 6-disulfonic acid couples and the resulting monoazo dye is treated with a copper-releasing substance.



  According to the present additional patent, you get a similar new dye if you use the 1 '. 8 - ani.nonaphtol - 3. 6 - diGulfosänre .by the 1st 8 - aminonaphtol - 4. 6 - disulfonic acid replaced.

      <I> Example: </I> 22.5 parts 1- Ogy -2- amino -4- chlorobenzene- 6-sulfonic acid are diazotized as usual and the diazo solution with an alkaline solution of 51.9 parts of the condensation product of salicylic acid sulfochloride and 1 . 8-amino naphtol - 4.

   6 - disulfonic acid coupled. The resulting monoazo dye is heated to 90 ° C. for 1 hour with the aqueous solution of 25 parts of crystallized copper sulfate and the copper compound is isolated by salting out. By boiling a solution of the copper compound in the presence of alkali, copper that is not complexed can be precipitated if necessary.



  The new copper-containing dye forms a violet powder when dried, dissolves in water with red-violet, in diluted caustic soda with blue-violet color and, when printed with chrome on cotton, artificial silk made from regenerated cellulose or on natural silk, produces lively, red-violet tones that are distinguished by good Distinguish fastness properties, in particular good light fastness.
