  <B>Zusatzpatent</B> zum Hauptpatent Nr. 115111    Verfahren zur     Herstellung    eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, wenn man den     Azofarbstoff     aus dianotierter     1-Amino-benzol-4-chlor-3-sul-          fosäure    und     Salizylsäure    mit     Chromichromat     behandelt.

   Der neue     Farbstoff    bildet ein gel  bes Pulver, löst sich in Wasser und in  10     o/oiger    Natronlauge     rnit    gelber Farbe und  färbt Wolle aus schwefelsaurem Bade in grün  stichiggelben Tönen mit guten Echtheitseigen  schaften.

           Beispiel:       37,8 Teile des     Farbstoffes    aus dianotier  ter     1-Aminobenzol-4-chlor-3-sirlfosäure    und       Salizylsäure    werden in 1200 Teilen Wasser  kochend gelöst und mit einer     7o/oigen        Chro-          michromatpaste,    hergestellt zum Beispiel aus       Natriumbichromat    und     Natriumthiosulfat,    de  ren     Gesamtchromgehalt    22,8 Teilen     Crs0a       entspricht, längere Zeit am     Rücliflusskühler     gekocht.

   Das überschüssige Chromoxyd wird  hierauf filtriert und der Farbstoff durch Ein  dampfen und     Aussalzen    isoliert.



  <B> Additional patent </B> to main patent no. 115111 Process for the production of a new dye. It has been found that a new dye is obtained if the azo dye consisting of dianotated 1-amino-benzene-4-chloro-3-sulphonic acid and salicylic acid is treated with chromium chromate.

   The new dye forms a yellow powder, dissolves in water and in 10% sodium hydroxide solution with a yellow color and dyes wool from a sulfuric acid bath in green, pale yellow shades with good fastness properties.

           Example: 37.8 parts of the dye from dianotier ter 1-aminobenzene-4-chloro-3-sirlfosäure and salicylic acid are dissolved in 1200 parts of boiling water and mixed with a 70% chromium chromate paste, prepared for example from sodium dichromate and sodium thiosulfate, de Ren total chromium content corresponds to 22.8 parts of Crs0a, cooked for a long time on the reflux cooler.

   The excess chromium oxide is then filtered and the dye is isolated by evaporating and salting out.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man den Azofarbstoff aus dianotierter 1-Amino- benzol-4-chlor-3-sulfosäure und Salizylsäure mit Chromichromat behandelt. Der neue Farb stoff bildet ein gelbes Pulver, löst sich in Wasser und in 10 o/oiger -Natronlauge mit gelber Farbe und färbt Wolle aus schwefel saurem Bade in grünstichiggelben Tönen mit guten i'chtheitseigenschaften. PATENT CLAIM: Process for the production of a new dye, characterized in that the azo dye from dianotated 1-amino-benzene-4-chloro-3-sulfonic acid and salicylic acid is treated with chromium chromate. The new dye forms a yellow powder, dissolves in water and in 10% sodium hydroxide solution with a yellow color and dyes wool from a sulfuric acid bath in greenish-yellow tones with good fastness properties.
