Description

  

  Verfahren zur Herstellung eines     metallhaltigen        Farbstoffes.       Es wurde gefunden, dass man einen me  tallhaltigen Farbstoff durch Behandeln des       Azofarbstoffes    aus     diazotiertem        4-Chlor-2-          amino-l-phenol    und     2-Aminonaphthalin    mit       kobaltabgebenden    Mitteln in alkalischem  Medium erhalten kann, wenn diese Behand  lung in Gegenwart von Salzen der Wein  säure erfolgt.  



  Der erhaltene     kobalthaltige        Farbstoff     stellt ein blauschwarzes Pulver dar, das in  organischen Lösungsmitteln mit blauvioletter  Farbe sehr leicht löslich ist, und aus einer  Lösung in     Nitro-    oder     Acetylzelluloselack     auf geeigneten Unterlagen, wie zum Beispiel  Metallfolien, blauviolette bis     violettschwarze     Überzüge gibt.  



  <I>Beispiel:</I>  14.3 Gewichtsteile     4-Chlor-2-amino-l.-          plieriol    werden mit 21 Teilen 30     0%iger    Salz  säure     und    6,9 Teilen     Natriumnitrit    in übli  cher Weise     diazotiert    und mit einer Lösung  von 15,3 Teilen     2-Aminonaphthalin    in 160    Teilen Wasser und 13,8 Teilen Salzsäure  bei 35-40  gekuppelt.

   Nach Beendigung  der Kupplung versetzt man mit 40 Teilen       30        %iger        Natronlauge        und        bei        450        mit     der aus 14,1 Teilen kristallisiertem Kobalt  sulfat, 3,75 Teilen Weinsäure und 26 Teile  Natronlauge erhaltenen     Kobaltlösung.    Nach  zweistündigem Erwärmen auf<B>65-700</B> wird  der ausgeschiedene     Farbstoff        abfiltriert,    neu  tral gewaschen und getrocknet.



  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-chloro-2-amino-1-phenol and 2-aminonaphthalene with cobalt-donating agents in an alkaline medium if this treatment is in the presence of salts of the wine acid takes place.



  The cobalt-containing dye obtained is a blue-black powder which is very easily soluble in organic solvents with a blue-violet color, and gives blue-violet to violet-black coatings from a solution in nitro or acetyl cellulose lacquer on suitable substrates, such as metal foils, for example.



  <I> Example: </I> 14.3 parts by weight of 4-chloro-2-amino-l-plieriol are diazotized in the usual way with 21 parts of 30% hydrochloric acid and 6.9 parts of sodium nitrite and then diazotized with a solution of 15 , 3 parts of 2-aminonaphthalene in 160 parts of water and 13.8 parts of hydrochloric acid at 35-40.

   After the coupling has ended, 40 parts of 30% strength sodium hydroxide solution are added and, at 450, the cobalt solution obtained from 14.1 parts of crystallized cobalt sulfate, 3.75 parts of tartaric acid and 26 parts of sodium hydroxide solution. After two hours of warming to <B> 65-700 </B>, the precipitated dye is filtered off, washed neutral and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines metall haltigen Farbstoffes durch Behandeln des Azofarbstoffes aus diazotiertem 4-Chlor-2- amino-l-phenol und 2-Aminonaphthalin mit kobaltabgebenden Mitteln in alkalischem Me dium, dadurch gekennzeichnet, dass diese Be handlung in Gegenwart von Salzen der Wein säure erfolgt. PATENT CLAIM: Process for the preparation of a metal-containing dye by treating the azo dye from diazotized 4-chloro-2-amino-1-phenol and 2-aminonaphthalene with cobalt-releasing agents in alkaline medium, characterized in that this treatment in the presence of salts of the Tartaric acid occurs. Der erhaltene kobalthaltige Farbstoff stellt ein blauschwarzes Pulver dar, das in organi- sehen Lösungsmitteln mit blauvioletter Farbe sehr leicht löslich ist und aus einer Lösung in Nitro- oder Acetylzelluloselack auf ge- eigneten -Unterlagen, wie zum Beispiel Me tallfolien, blauviolette bis violettschwarze Überzüge gibt.
