  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 165155.    Verfahren zur Herstellung eines metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen me  tallhaltigen Farbstoff durch Behandeln des       Azofarbstoffes    aus     diazotiertem        4-Nitro-2-          amino-l-phenol    und     1-Phenyl-3-methyl-5-          pyrazolon    mit     manganabgebenden    Mitteln in  alkalischem Medium erhalten kann, wenn  diese Behandlung in Gegenwart von Salzen  der Zitronensäure erfolgt.  



  Der erhaltene     manganhaltige    Farbstoff  stellt ein gelbrotes Pulver dar, das in Alkohol  mit oranger Farbe löslich ist und aus einer  Lösung in     Nitrozelluloselack    auf geeigneten  Unterlagen gelborange gefärbte Überzüge gibt.

      <I>Beispiel:</I>  6,72 Teile des Farbstoffes aus dianotier  tem     4-Nitro-2-amino-l-phenol    und     1-Phenyl-          3-methyl-5-pyrazolort    werden in 400 Teilen  Wasser und 2,7 Teilen     3011/oiger    Natronlauge  aufgeschlämmt und mit einer Lösung aus  4,6 Teilen kristallisiertem     Mangansulfat,    30  Teilen Wasser, 8,5 Teilen Zitronensäure und  20 Teilen     3011/oiger    Natronlauge kurze Zeit    am     Rückfluss    zum Kochen erhitzt. Nach dem  Erkalten neutralisiert man     rnit    Essigsäure,  filtriert den ausgeschiedenen     Farbstoff    ab  und trocknet.



  <B> Additional patent </B> to main patent no. 165155. Process for the production of a metal-containing dye. It has been found that a metal-containing dye can be obtained by treating the azo dye from diazotized 4-nitro-2-amino-1-phenol and 1-phenyl-3-methyl-5-pyrazolone with manganese-releasing agents in an alkaline medium, if these Treatment takes place in the presence of salts of citric acid.



  The resulting manganese-containing dye is a yellow-red powder which is soluble in alcohol with an orange color and, from a solution in nitrocellulose varnish, gives yellow-orange colored coatings on suitable substrates.

      <I> Example: </I> 6.72 parts of the dye from dianotier tem 4-nitro-2-amino-1-phenol and 1-phenyl-3-methyl-5-pyrazole are in 400 parts of water and 2.7 Parts of 3011 /% sodium hydroxide solution slurried and heated to the boil under reflux for a short time with a solution of 4.6 parts of crystallized manganese sulfate, 30 parts of water, 8.5 parts of citric acid and 20 parts of 3011 /% sodium hydroxide solution. After cooling, it is neutralized with acetic acid, the precipitated dye is filtered off and dried.
