      Zusatzpatent    zum Hauptpatent Nr. 307327.    Verfahren zur     Herstellung    eines wasserlöslichen und     beizenziehenden          Azophthalocyaninfarbstoffes.       Die     vorliegende    Erfindung betrifft ein       Verfahren    zur Herstellung eines wasserlösli  chen und     beizenziehenden        Azophthalocyanin-          fa.rbstoffes,    welches dadurch gekennzeichnet  ist, dass man 1     Mol        Chromphthalocyanin-4,4',          4",

  4'"-tetrasulfochlorid    mit 3     Mol        3-Amino-4'-          oxv-1,1.'-azobenzol-5'-carbonsäure    in Gegen  wart einer Mineralsäure neutralisierenden  Substanz zur Umsetzung bringt. Im übrigen  gelten die Ausführungen, welche im Haupt  patent gemacht wurden.  



  Das     naelistehende    Beispiel erläutert das       neue    Zerfahren. Die angegebenen Teile bedeu  ten Gewichtsteile.  



       Beispiel:     47,9 Teile (1/20     Mol)        Chromphthalocyanin-          4,4',4",4"'    -     tetx-asulfoehlorid,    erhalten durch  Einwirkung von     Chlorsulfonsäure    auf     Chrom-          phthaloeyanin    - 4,4',4",4"' -     tetrasulfonsäure,     werden auf Eis ausgeladen und das abge  trennte Reaktionsprodukt als feuchte Paste  einer Lösung von 42 Teilen (3/20     Mol)    des       Natriumsalzes    der     3-Amino-4'-oxy-1.,1'-a.zoben-          zol-5'-carbonsä.ure    in 300 Teilen Wasser,

   der  man noch 20 Teile     Calciumearbonat    zufügte,  rasch zugegeben. Man lässt zunächst während  10 Stunden bei     1.0 C    und hernach während  40 Stunden bei<B>20-250</B> C rühren. Der Parb-    Stoff wird auf übliche Weise in Form eines       Natriumsalzes    isoliert.  



  Der so erhaltene Farbstoff stellt ein dun  kelgrünes Pulver dar, das sich in Wasser mit  grüner und in     konz.    Schwefelsäure mit gelb  brauner Farbe löst.  



  Der neue Farbstoff liefert im Chromdruck  auf Baumwolle olivgrüne Farbtöne von sehr  guten Echtheitseigenschaften.



      Additional patent to main patent no. 307327. Process for the production of a water-soluble and co-licensing azophthalocyanine dye. The present invention relates to a process for the production of a water-soluble and licensing azophthalocyanine dye, which is characterized in that 1 mole of chromophthalocyanine-4,4 ', 4 ",

  4 '"- tetrasulfochloride with 3 moles of 3-amino-4'-oxv-1,1 .'-azobenzene-5'-carboxylic acid in the presence of a mineral acid neutralizing substance for implementation. Otherwise, the statements in the main patent apply were made.



  The following example explains the new disintegration. The specified parts mean parts by weight.



       Example: 47.9 parts (1/20 mol) chromium phthalocyanine 4,4 ', 4 ", 4"' - tetx-asulfoehlorid, obtained by the action of chlorosulfonic acid on chromophthalocyanine - 4,4 ', 4 ", 4" '- Tetrasulfonic acid, are unloaded onto ice and the separated reaction product as a moist paste of a solution of 42 parts (3/20 mol) of the sodium salt of 3-amino-4'-oxy-1., 1'-a.zoben- zol -5'-carboxylic acid in 300 parts of water,

   to which 20 parts of calcium carbonate were added, quickly added. The mixture is initially stirred for 10 hours at 1.0 ° C. and then for 40 hours at 20-250 C. The Parb substance is isolated in the usual way in the form of a sodium salt.



  The dye obtained in this way is a dark green powder that differs in water with green and in conc. Sulfuric acid dissolves with a yellow-brown color.



  In chrome printing on cotton, the new dye provides olive green shades with very good fastness properties.
