  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 152880.    Verfahren zur Herstellung     eines        chromhaltigen        Farbstoffes.       Es     wurde    gefunden, dass ein neuer     chrom-          haltiger    Farbstoff, der auf jede     chromierbare     Gruppe des     Farbstoffmoleküls    1 Atom Chrom  enthält, erhalten wird, wenn man den Farb  stoff aus dianotierter     1-Amino-2-oxynaph-          thalin-4-sulfosäure    und     2-Oxynaphthalin    mit  Chromsulfat behandelt.  



  Der gebildete Farbstoff stellt ein dunkel  gefärbtes Pulver dar, das sich in verdünnter  Soda mit     rotstichig    blauer Farbe löst und  Wolle aus schwefelsaurem Bade in blauen  Tönen färbt.  



  <I>Beispiel:</I>  39,4 Teile des     Farbstoffes    aus dianotierter       1-Ainino-2-oxyna,phthalin-4-sulfosäure    und       2-Oxynaphthä,lin    werden in 2000 Teilen Wasser  aufgekocht und mit einer aus 9,1 Teilen       Cr20s    und 11,7 Teilen     H2804    erhaltenen       Clu-omsulfatlösung    während 30-40 Stunden    am     Rückflusskühler    zum lochen erhitzt. Die  Chromverbindung scheidet sich aus; sie wird  nach dem Erkalten     abfiltriert    und bei mässiger  Temperatur getrocknet.



  <B> Additional patent </B> to the main patent No. 152880. Process for the production of a chromium-containing dye. It has been found that a new chromium-containing dye which contains 1 atom of chromium for each chromable group of the dye molecule is obtained when the dye is obtained from dianotized 1-amino-2-oxynaphthalene-4-sulfonic acid and 2- Oxynaphthalene treated with chromium sulfate.



  The dye formed is a dark-colored powder that dissolves in dilute soda with a reddish-tinged blue color and dyes wool from sulfuric acid bath in blue tones.



  <I> Example: </I> 39.4 parts of the dye from dianotized 1-alino-2-oxyna, phthalene-4-sulfonic acid and 2-oxynaphtha, lin are boiled in 2000 parts of water and mixed with one from 9.1 parts Cr20s and 11.7 parts H2804 obtained Clu-omsulfatlösung heated for 30-40 hours on the reflux condenser to punch. The chromium compound separates out; it is filtered off after cooling and dried at a moderate temperature.

PATENTANSPRUCH: Verfahren zur Herstellung eines chrom- haltigen Farbstoffes, der auf jede chromierbare Gruppe des Farbstoffmoleküls 1 Atom Chrom enthält, dadurch gekennzeichnet, dass man den Farbstoff aus dianotierter 1-Ainino-2-oxy- riaphthalin-4-sulfosäure und 2-Oxynaphthalin mit Chromsulfat behandelt. Der gebildete Farbstoff stellt ein dunkel gefärbtes Pulver dar, das sich in verdünnter Soda mit rotstichig blauer Farbe löst und Wolle aus schwefelsaurem Bade in blauen Tönen färbt. PATENT CLAIM: A process for the production of a chromium-containing dye which contains 1 atom of chromium for each chromable group of the dye molecule, characterized in that the dye is made from dianotated 1-amino-2-oxyriaphthalene-4-sulfonic acid and 2-oxynaphthalene Chromium sulfate treated. The dye formed is a dark-colored powder that dissolves in dilute soda with a reddish-tinged blue color and dyes wool from sulfuric acid bath in blue tones.
