Description

  

      -Verfahren    zur Herstellung eines     Farbstoffzwischenproduktes.       Es wurde gefunden,     dass    ein wertvolles       Farbstoffzwischenprodukt    erhalten wird.  wenn man     5.5'.5".5"'-Tetrahalogenkupfer-          phthalocyanin-4    . 4' . 4" .     4"'=tetrasulfosäureu     mit     wässrigem    Ammoniak erhitzt.

   Die Um  setzung wird zweckmässig in Gegenwart von       Kupfer        oder    Kupfersalzen     durchgeführt.    An       Stelle        eines        Cupros:alzes    kann man auch die  Mischung eines     Cuprisalzes    mit Kupfer ver  wenden.  



       Das    erhältliche     Farbstoffzwischenpro-          dukt    ist sowohl in Säuren als auch in     Alka-          lien    löslich, und zwar in -ersteren mit einer       rotstichig    blauen und in letzteren     mit        einer          s    stumpfen blaugrünen Färbung.

   Es ist     acy-          lierbar,    wobei je nach .der Natur der einge  führten     Acylgruppe    Farbstoffe mit mehr  oder minder     gelbstichig    grüner Nuance und  ausgezeichneten Echtheitseigenschaften     ent-          o        stehen.       <I>Beispiel:

  </I>  Ein Gemisch von 500 Gewichtsteilen  27 %     igem    Ammoniak, 0,5 Gewichtsteilen    Kupferbronze, 1,0 Gewichtsteilen Kupfer  chlorid, 50 Gewichtsteilen der 5     .5'.    5". 5"'- 2       Tetrabromkupf        erphthalocyanin    - 4 . 4'. 4".     4'"-          tetrasulf        osäure    (als     Natriumsalz)    wird in  einem     Autoklaven    unter Rühren zirka 10       .Stunden    auf 155-165  erhitzt. Der abge  schiedene Niederschlag wird     abfiltriert,    in ;  Wasser gelöst und von ungelösten Verunrei  nigungen befreit.

   Anschliessend wird das       Farbstoffzwischenproduktdurch    Zugabe von  Kochsalz Busgesalzen.  



  An Stelle der oben erwähnten     Tetrabrom-          verbindung    kann mit dem gleichen Erfolg  eine äquivalente Menge der entsprechenden       Tetrachlorverbindung    benutzt werden.



      -Process for the preparation of a dye intermediate. It has been found that a valuable intermediate dye is obtained. if one 5.5'.5 ".5" '- tetrahalocopper phthalocyanine-4. 4 '. 4 ". 4" '= tetrasulfonic acid heated with aqueous ammonia.

   The implementation is expediently carried out in the presence of copper or copper salts. Instead of a cupro salt, you can also use a mixture of a cupric salt with copper.



       The obtainable intermediate dye product is soluble both in acids and in alkalis, namely in the former with a reddish-tinged blue and in the latter with a dull blue-green color.

   It can be acylated, and depending on the nature of the acyl group introduced, dyes with a more or less yellowish green shade and excellent fastness properties are formed. <I> example:

  </I> A mixture of 500 parts by weight of 27% ammonia, 0.5 part by weight of copper bronze, 1.0 part by weight of copper chloride, 50 parts by weight of the 5 .5 '. 5 ". 5" '- 2 tetrabromo copper phthalocyanine - 4. 4 '. 4 ". 4 '" - tetrasulfonic acid (as sodium salt) is heated in an autoclave with stirring for about 10 hours to 155-165. The deposited precipitate is filtered off, in; Dissolved water and freed from undissolved impurities.

   The intermediate dye product is then bus salts by adding table salt.



  In place of the above-mentioned tetrabromo compound, an equivalent amount of the corresponding tetrachloro compound can be used with the same success.
