  <B>Zusatzpatent</B> zum Hauptpatent Nr. 310250    Verfahren     zur        Herstellung        eines        metallisierbaren        Polyazofarbstoffes       Gegenstand des vorliegenden Patentes ist       ein    Verfahren     zur    Herstellung eines     metalli-          sierbaren        Polyazofarbstoffes,    welches darin  besteht, dass man 1     Mol        tetrazotiertes        4,4'-          Diamino-3,3'-dimethoxy    -1,

  1' -     diphenyl    einer  seits mit 1     Mol    der durch saures Kuppeln  von     diazotiertem        2-Amino-l-oxy-4-methylsul-          fonylbenzol    mit     2-Phenylamino-5-oxynaphtha-          lin-7-sixlfonsäure    erhältlichen     Aminomonoazo-          verbindung    und anderseits mit 1     Mol        2-Oxy-          naphthalin    kuppelt.  



  Im nachfolgenden Beispiel bedeuten die  Teile Gewichtsteile.  



  <I>Beispiel</I>  24,4 Teile     4,4'-Diamino-3"3'-dimethoxy-1,1'-          diphenyl    werden mit 65 Teilen konzentrierter  Salzsäure und 13,8 Teilen     Natriumnitrit    bei  0 bis 5      tetrazotiert.    Man versetzt die     Tetrazo-          lösung    mit einer     alkalischen        Lösung    von  51,

  3 Teilen der durch saures     Kuppeln    von  1     Mol        diazotiertem        2-Amino-l-oxy-4-methyl-          sulfonylbenzol    mit 1     Mol        2-Phenylamino-5-          oxynaphthalin    - 7 -     sulfonsäure    erhältlichen       Aminomonoazoverbindung    und 10 Teilen       Natriumearbonat    in 1000 Teilen Wasser.

    Hierauf fügt man der Reaktionsmasse  eine Lösung von. 50 Teilen     Natrium-          earbonat    in 250 Teilen Wasser zu, wor  auf sehr rasch     einseitige    Kupplung zwi  schen     Tetrazokörper    und     Aminomonoazover-          bindung    eintritt. Die so gebildete Zwischen-         verbindung    fällt vollständig aus.

   Sobald der       Tetrazokörper    völlig verschwunden ist,     wird     die Reaktionsmasse mit einer Lösung von  15,2 Teilen     2-Oxynaphthalin,    4 Teilen Na  triumhydroxyd und 100 Teilen eines techni  schen     Pyridinbasengemisches    in 300 Teilen  Wasser vereinigt. Nach mehrstündigem Rüh  ren der Reaktionsmasse ist die Bildung des       Trisazofarbstoffes    beendet. Er wird mit Na  triumchlorid abgeschieden, hierauf     abfiltriert     und getrocknet.  



  Der neue,     metallisierbare        Polyazofarb-          stoff    ist ein     dunkles        Pulver,    das sich in Was  ser mit     dunkelblauer    Farbe löst     und    Baum  wolle und Fasern aus regenerierter     Cellu-          lose    nach dem ein- oder     zweibadigen    Nach  kupferungsverfahren in marineblauen Tönen       vön    sehr guten Nass- und Lichtechtheits  eigenschaften färbt.



  <B> Additional patent </B> to main patent no. 310250 Process for the production of a metallizable polyazo dye The subject of the present patent is a process for the production of a metallizable polyazo dye, which consists in adding 1 mol of tetrazotized 4,4'-diamino- 3,3'-dimethoxy -1,

  1 '- diphenyl on the one hand with 1 mol of the aminomonoazo compound obtainable by acidic coupling of diazotized 2-amino-1-oxy-4-methylsulfonylbenzene with 2-phenylamino-5-oxynaphthalin-7-sixlfonic acid and on the other hand with 1 Mole of 2-oxynaphthalene couples.



  In the following example, the parts are parts by weight.



  <I> Example </I> 24.4 parts of 4,4'-diamino-3 "3'-dimethoxy-1,1'-diphenyl are tetrazotized at 0-5 with 65 parts of concentrated hydrochloric acid and 13.8 parts of sodium nitrite. The tetrazo solution is mixed with an alkaline solution of 51,

  3 parts of the aminomonoazo compound obtainable by acid coupling of 1 mole of diazotized 2-amino-1-oxy-4-methylsulfonylbenzene with 1 mole of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid and 10 parts of sodium carbonate in 1000 parts of water.

    Then you add a solution of the reaction mass. 50 parts of sodium carbonate in 250 parts of water are added, whereupon one-sided coupling between tetrazo bodies and aminomonoazo compound occurs very quickly. The intermediate connection formed in this way fails completely.

   As soon as the tetrazo body has completely disappeared, the reaction mass is combined with a solution of 15.2 parts of 2-oxynaphthalene, 4 parts of sodium hydroxide and 100 parts of a technical pyridine base mixture in 300 parts of water. After several hours of stirring the reaction mass, the formation of the trisazo dye is complete. It is precipitated with sodium chloride, then filtered off and dried.



  The new, metallisable polyazo dye is a dark powder that dissolves in water with a dark blue color, and cotton and fibers made from regenerated cellulose after the one or two bath post-copper plating process in navy blue tones with very good wet and lightfastness properties colors.
