Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 261978.    Verfahren zur Herstellung eines graugrünen Farbstoffes der     Phthaloeyaninreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur     Herstellung    eines graugrünen  Farbstoffes der     Phthalocyaninreihe,    das da  durch gekennzeichnet ist, dass man symmetri  sches Tetra     -p-thiokresoxy-eisenphthalocyanin     mit sulfonierenden Mitteln behandelt.  



  <I>Beispiel:</I>  10 Gewichtsteile symmetrisches     Tetra-p-          thiokresoxy-eisenphthalocyanin,    erhältlich     aus     symmetrischem     Tetrachloreisenphthalocyanin     und     p-Thiokresol,    werden in der sechsfachen       Menge        Schwefelsäure        von        95        bis        100%        gelöst     und bei 70 bis 120  so lange gerührt, bis die         Sulfonierung    beendet ist. Der in üblicher  Weise isolierte Farbstoff färbt Papier in grau  grünen Tönen an.

   Der Farbstoff löst sich in  konzentrierter Schwefelsäure mit     braunoliver     Farbe.



  <B> Additional patent </B> to main patent No. 261978. Process for the production of a gray-green dye of the phthaloeyanine series. The present patent relates to a process for the production of a gray-green dye of the phthalocyanine series, which is characterized in that symmetrical tetra-p-thiocresoxy-iron phthalocyanine is treated with sulfonating agents.



  <I> Example: </I> 10 parts by weight of symmetrical tetra-p-thiocresoxy-iron phthalocyanine, obtainable from symmetrical tetrachloroiron phthalocyanine and p-thiocresol, are dissolved in six times the amount of 95 to 100% sulfuric acid and stirred at 70 to 120 for as long as until the sulfonation has ended. The dye, isolated in the usual way, stains paper in gray-green tones.

   The dye dissolves in concentrated sulfuric acid with an olive-brown color.
