  Imperial     Chemical        Industries        Limited,    London (Grossbritannien).  Verfahren zur Herstellung eines neuen     Phthaloeyaninderivates.       Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Herstellung eines neuen       Phthalocyaninfarb,stoff    -     Zwischenproduktes,     welches dadurch gekennzeichnet ist, dass Kup  fer -     tetra    - 4     -(in    -     nitrobenzol        -,sulfonylamino)

          -          phthalocyanin    zum     Kupfer-tetra-4-(m-arnino-          henzol-sulfonylamino)-phthalocyanin.    redu  ziert wird.  



  Die Reduktion lässt sich in der für die Re  duktion von     Nitroverbindungen    zu     Aminover-          bindungen    bekannten Weise, beispielsweise  durch Einwirkung von     Alkalimetallsulfiden,          Schwefelwasserstoffen,    Polysulfiden,     Sulfi-          ten,        Bis.ulfiten    oder     Hydrosulfiten,    oder mit  Hilfe von Zinn,     Zink,    oder     Stannochlorid    und  Säure durchführen.  



  Das erfindungsgemäss anfallende neue       Phthalocyaninzwischenprodukt    ist ein dunk  les,     bläulichgrünes,    festes Produkt, welches  in Wasser unlöslich ist, jedoch unter Bildung  einer     Diazoniumverbindung,    welche zur Her  stellung von     Azofarbstoffen    Verwendung fin  den kann,     diazotiert    werden kann.

           Beispiel:       Die     i(1%ige    Paste von     Kupfer-tetra-4-          (m-nitrobenzol-sulfonylamino)-pht3ialocyanin     (erhalten in der weiter unten beschriebenen  Weise) wird bei 0, bis 5  C gerührt und     mit     147 Teilen     konz.    Salzsäure vom     spez.        Gew.     1,18 versetzt.

   Dann wird eine     Lösung    von 160  Teilen     Stannochlorid-Dihydrat    in 200     Teilen     Wasser hinzugegeben und das     Gemisch    wäh-         rend    16 Stunden gerührt, wobei man die Tem  peratur langsam auf 20 C     ansteigen    lässt. Das       Produktwirdfiltriertunddaszurückbleibende     feste Produkt so lange     gründlich    mit ver  dünnter Salzsäure gewaschen, bis es keine  Zinnsalze mehr enthält, worauf     es    mit Was  ser und schliesslich mit verdünnter     Ammo-          niumhydrogydlösung    gewaschen wird.

   An- ,  schliessend wird noch so lange gewaschen, bis  der Rückstand     ammoniakfrei    ist. Das so er  haltene     Kupfer-tetra-4-(m-aminobenzol-sul-          fonylamino)-phthalocyanin    kann zu einem       dunkelbläulichgrünen    Produkt getrocknet.  werden, doch wird man es zu Gebrauchs  zwecken     vortelhafterweise    in Form einer       wässrigen    Paste     aufbewahren.     



  Die     wässrige    Paste des in diesem     Beispiel     verwendeten     Kupfer-tetra-4-(m-nitrobenzol-          sulfonylamino)-phthalocyanins    wird wie     folgt     hergestellt:  Eine     wässrige,   <B>10,5</B> Teile     Kupfer-tetra-4-          aminophthalocyanin    enthaltende Paste wird  filtriert und der Filterkuchen mit Aceton ge  waschen, bis er wasserfrei ist.

   Hierauf     wird     der     acetonfeuchte    Filterkuchen in<B>178</B> Teile  trockenes Nitrobenzol eingetragen und die  Temperatur des so erhaltenen Gemisches der  massen erhöht, bis das Aceton     abdestilliert    ist.  Dann versetzt man diese Suspension mit 50  Teilen     m-Nitrobenzol-sulfonylchlorid    und  lässt die Temperatur auf 180 C ansteigen,  welche während 8 Stunden aufrechterhal  ten wird. Das erzielte Gemisch     wird    auf      100  C gekühlt, mit     25G    Teilen     heissem        Ätha-          nol        verdünnt    und filtriert.

   Der Filterkuchen  wird mit 200     Teilen        heissem    Äthanol     dige-          riert    und filtriert; dieser Vorgang wird so  lange wiederholt,     bis        ein    farbloses. Filtrat er  halten wird. Dann wird der Filterkuchen zur  Beseitigung des Alkohols gründlich     mit    Was  ser gewaschen und schliesslich mit Wasser       angeteig-t,    um eine annähernd 10 %     ige    Paste  zu erhalten.



  Imperial Chemical Industries Limited, London (Great Britain). Process for the production of a new phthaloeyanine derivative. The present invention relates to a process for the production of a new phthalocyanine dye, intermediate product, which is characterized in that copper - tetra - 4 - (in - nitrobenzene -, sulfonylamino)

          - phthalocyanine to copper tetra-4- (m-arninohenenzene-sulfonylamino) phthalocyanine. is reduced.



  The reduction can be carried out in the manner known for reducing nitro compounds to amino compounds, for example by the action of alkali metal sulfides, hydrogen sulfides, polysulfides, sulfites, bisulfites or hydrosulfites, or with the aid of tin, zinc, or stannous chloride and Perform acid.



  The novel phthalocyanine intermediate product obtained according to the invention is a dark, bluish-green, solid product which is insoluble in water, but can be diazotized to form a diazonium compound which can be used for the manufacture of azo dyes.

           Example: The 1% paste of copper-tetra-4- (m-nitrobenzene-sulfonylamino) -pht3ialocyanine (obtained in the manner described below) is stirred at 0 ° to 5 ° C. and mixed with 147 parts of concentrated hydrochloric acid from specific weight 1.18 offset.

   Then a solution of 160 parts of stannous chloride dihydrate in 200 parts of water is added and the mixture is stirred for 16 hours, the temperature being allowed to rise slowly to 20.degree. The product is filtered and the remaining solid product is washed thoroughly with dilute hydrochloric acid until it no longer contains any tin salts, whereupon it is washed with water and finally with a dilute ammonium hydrogen solution.

   Subsequently, washing is continued until the residue is free of ammonia. The copper tetra-4- (m-aminobenzene-sulphonylamino) -phthalocyanine obtained in this way can be dried to give a dark bluish-green product. , but it will advantageously be kept in the form of an aqueous paste for use purposes.



  The aqueous paste of the copper tetra-4- (m-nitrobenzenesulfonylamino) phthalocyanine used in this example is prepared as follows: An aqueous paste containing <B> 10.5 </B> parts of copper-tetra-4-aminophthalocyanine The paste is filtered and the filter cake is washed with acetone until it is anhydrous.

   The filter cake moist with acetone is then introduced into 178 parts of dry nitrobenzene and the temperature of the mixture of masses thus obtained is increased until the acetone has distilled off. This suspension is then mixed with 50 parts of m-nitrobenzenesulfonyl chloride and the temperature is allowed to rise to 180 ° C., which is maintained for 8 hours. The resulting mixture is cooled to 100 ° C., diluted with 25G parts of hot ethanol and filtered.

   The filter cake is digested with 200 parts of hot ethanol and filtered; this process is repeated until a colorless one. Filtrate he will hold. The filter cake is then washed thoroughly with water to remove the alcohol and finally made into a paste with water to obtain an approximately 10% paste.
