  <B>Zusatzpatent</B> zum Hauptpatent Nr.<B>261978.</B>    Verfahren zur Herstellung eines grünen Farbstoffes der     Phthaloeyaninreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Herstellung eines grünen Farbstof  fes der     Phthalocyaninreihe,    das dadurch ge  kennzeichnet ist, dass man symmetrisches     Te-          trathiophenoxykupferphthalocyanin    mit     Chlor-          sulfonsäure    sulfoniert.  



  <I>Beispiel:</I>  10 Gewichtsteile     symmetrisches        Tetrathio-          phenoxykupferphthalocyanin,    erhalten nach  dem Schweizer Patent Nr. 269708, werden in  120 Gewichtsteilen Chlorbenzol verrührt und  mit 4,5 bis 6 Gewichtsteilen     Chlorsulfonsäure     versetzt, worauf man so lange auf dem Was  serbad erwärmt; bis die     Farbstoffbildung    be  endet ist     und    eine Probe nach Entfernen des  Chlorbenzols in Wasser vollständig löslich ge-    worden ist. Es wird nun     mit    Wasser verrührt,  das Chlorbenzol mit Wasserdampf abgetrieben  und der Farbstoff durch Fällen mit Kochsalz,  Filtration und Auswaschen mit verdünnter  Kochsalzlösung isoliert.

   Der Farbstoff färbt  Papier, Baumwolle und Seide in schönen grü  nen Tönen.



  <B> Additional patent </B> to main patent no. <B> 261978. </B> Process for the production of a green dye from the phthaloeyanine series. The present patent relates to a process for producing a green dye of the phthalocyanine series, which is characterized in that symmetrical tetrathiophenoxy copper phthalocyanine is sulfonated with chlorosulfonic acid.



  <I> Example: </I> 10 parts by weight of symmetrical tetrathiophenoxy copper phthalocyanine, obtained according to Swiss Patent No. 269708, are stirred in 120 parts by weight of chlorobenzene and mixed with 4.5 to 6 parts by weight of chlorosulfonic acid, whereupon the bath is kept on for a long time warmed; until the dye formation has ended and a sample has become completely soluble in water after the chlorobenzene has been removed. It is then stirred with water, the chlorobenzene is driven off with steam and the dye is isolated by precipitation with sodium chloride, filtration and washing with dilute sodium chloride solution.

   The dye dyes paper, cotton and silk in beautiful green tones.
