Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>141535.</B>         Verfahren    zur Herstellung eines     metallhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen  neuen metallhaltigen Farbstoff erhält, wenn  man den Farbstoff aus     diazotiertem        2-          Amino-l-naphthol    und     1-(o'-Chlorphenyl)-3-          methyl-5-pyrazolon    in Gegenwart von     Al-          kalien    mit aluminiumabgebenden Mitteln be  handelt.  



  Die     Aluminiumverbindung    des Farbstof  fes ist in organischen Lösungsmitteln mit  blaustichig roter     Farbe    löslich     und    ergibt  aus einer Lösung in     Zaponlack    auf Metall  folien blaurote Überzüge.  



  <I>Beispiel:</I>  7,58 Teile des Farbstoffes aus     diazotier-          tem        2-Amino-l-naphthol    und     1-(o'-Chlor-          phenyl)    - 3 -     methyl    - 5 -     pyrazolon    werden in  500 Teilen Wasser und 10 Teilen Natronlauge  von 36       Be    aufgekocht und mit einer Lö  sung von 3,4 Teilen Aluminiumsulfat in 50  Teilen Wasser und 20 Teilen Natronlauge    eine Stunde im Sieden gehalten. Nach dem  Erkälten wird mit Essigsäure neutralisiert  und der metallhaltige Farbstoff abgeschie  den.



      Additional patent to main patent no. <B> 141535. </B> Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye is obtained from diazotized 2-amino-1-naphthol and 1- (o'-chlorophenyl) -3-methyl-5-pyrazolone in the presence of alkalis with aluminum-releasing agents Funds treated.



  The aluminum compound of the dyestuff is soluble in organic solvents with a bluish red color and, from a solution in zapon varnish on metal foils, produces blue-red coatings.



  <I> Example: </I> 7.58 parts of the dye from diazotized 2-amino-1-naphthol and 1- (o'-chlorophenyl) -3-methyl-5-pyrazolone are in 500 parts of water and 10 parts of 36 Be sodium hydroxide solution and boiled with a solution of 3.4 parts of aluminum sulfate in 50 parts of water and 20 parts of sodium hydroxide solution for one hour. After cooling, it is neutralized with acetic acid and the metal-containing dye is deposited.
