  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-          farbstoffes,    welches dadurch gekennzeichnet  ist, dass man 1     Mol        Kupferphthalocyanin-3,3'-          3",3"'-tetra-sulfochlorid    mit 1     142o1        4-Amino-2-          methyl-5-methoxy-        2'-oxy-1,

  1'-azobenzol-3'-car-          bonsäure    in Gegenwart einer Mineralsäure  neutralisierenden Substanz zur Umsetzung       bringt.    Im übrigen gelten die     Ausführungen,     wie sie im Hauptpatent gemacht wurden.  



  Das nachstehende Beispiel erläutert das  neue Verfahren. Die angegebenen Teile bedeu  ten Gewichtsteile.  



  <I>Beispiel:</I>       -18,5    Teile     (1/2oMol)        Kupferphthalocyanin-          3,3',3",3l"    -     tetrasulfochlorid,    erhalten durch  Einwirkung von     Chlorsulfonsäure    auf     Kup-          ferphthaloeyanin,    werden als feuchte Paste in  eine     Lösung,    bestehend aus 17 Teilen (1/20       1-1o1)    des     Kaliumsalzes    der     4-Amino-2-methyl-          5-methoxy='-oxy-1,1'-azobenzol-3'-carbonsäure     in 400 Teilen Wasser und 25 Teilen     Pyridin,

       bei 0-5  C eingetragen und bei dieser     Tem-          perat        .ur    24 Stunden rühren gelassen. Der  Farbstoff wird durch Ansäuern abgetrennt,    von anhaftenden     Verunreinigungen    befreit  und als     Natriumsalz    isoliert.  



  Der so erhaltene Farbstoff stellt ein graues  Pulver dar, das sich in Wasser mit blaugrüner  und in     konz.    Schwefelsäure mit dunkelbrauner  Farbe löst. Im Chromdruck werden blau  stichig grüne Farbtöne von guten Echtheits  eigenschaften erhalten.



  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 preparation of a water-soluble and associated azophthalocyanine dye, which is characterized in that 1 mol of copper phthalocyanine-3,3'- 3 ", 3" '- tetra-sulfochloride with 1 142o1 4-amino 2- methyl-5-methoxy-2'-oxy-1,

  1'-azobenzene-3'-carboxylic acid in the presence of a mineral acid neutralizing substance brings to implementation. Otherwise, the statements made in the main patent apply.



  The following example illustrates the new procedure. The specified parts mean parts by weight.



  <I> Example: </I> -18.5 parts (1 / 2oMol) of copper phthalocyanine 3,3 ', 3 ", 3l" - tetrasulfochloride, obtained by the action of chlorosulfonic acid on copper phthaloeyanine, are in a moist paste Solution consisting of 17 parts (1/20 1-1o1) of the potassium salt of 4-amino-2-methyl-5-methoxy = '- oxy-1,1'-azobenzene-3'-carboxylic acid in 400 parts of water and 25 Share pyridine,

       entered at 0-5 ° C. and left to stir at this temperature for only 24 hours. The dye is separated off by acidification, freed from adhering impurities and isolated as the sodium salt.



  The dye obtained in this way is a gray powder which turns blue-green in water and in conc. Sulfuric acid dissolves with a dark brown color. In chrome printing, blue, green shades with good fastness properties are obtained.
