Description

  

      Gnsatzpatent    zum Hauptpatent Nr. 261978.    Verfahren zur Herstellung     eines    gelbgrünen Farbstoffes der     Phthaloeyaninreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur     Herstellung    eines neuen gelbgrü  nen Farbstoffes der     Phthalocyaninreihe,    das  dadurch gekennzeichnet. ist, dass man das sym  metrische Tetra- (2)     -thionaphthoxy-kupfer-    .       phthalocyanin    mit     sulfonierenden    Mitteln be  handelt.  



  <I>Beispiel:</I>  10 Teile     symmetrisches    Tetra- (2)     -thio-          naphthoxy-kupferphthalocyanin,    erhalten nach  dem Schweizer     PatentNr.   <B>269710,</B> werden in der  vier- bis sechsfachen Menge Monohydrat gelöst.  und bei 200 so lange gerührt, bis eine Probe    in Wasser löslich geworden ist. Der gelbgrüne  Farbstoff wird in üblicher Weise isoliert und  färbt Papier gelbgrün an.



      Additional patent for main patent No. 261978. Process for the production of a yellow-green dye of the phthaloeyanine series. The present patent relates to a process for the production of a new yellow-green dye of the phthalocyanine series, which is characterized. is that one has the symmetrical tetra- (2) -thionaphthoxy-copper-. phthalocyanine with sulfonating agents.



  <I> Example: </I> 10 parts of symmetrical tetra- (2) -thio- naphthoxy-copper phthalocyanine, obtained according to the Swiss patent no. <B> 269710, </B> are dissolved in four to six times the amount of monohydrate. and stirred at 200 until a sample has become soluble in water. The yellow-green dye is isolated in the usual way and stains paper yellow-green.
