PATENTANSPRUCH: Verfahren zur Herstellung eines eliroiri- haltigen Azofarbstoffes, dadurch gekenn- zeichnet. dass man den o-OYy-o-aminoazofarli- stoff aus ss-1Taphthyl.a.min un:cl d-117_ctllyl-?- amino - 1 - Phenol - 5 - sulfosäure mit Chroin- formiat behandelt. PATENT CLAIM: Process for the production of an azo dye containing eliroiri, characterized thereby. that the o-OYy-o-aminoazofarli- substance from ss-1Taphthyl.a.min un: cl d-117_ctllyl -? - amino - 1 - phenol - 5 - sulfonic acid is treated with chromoformate. Der so gewonnene ehronl- haltige Azofarbstoff bildet ein schwärzliches Pulver. dessen wässerige Lösungen in dünner Schicht blau und in dickerer Schicht violeit erscheinen. Fr färbt Wolle aus saurem Bade in grünen Farbtönen von ausgezeichneten Lchtheitseigens-chaften. The azo dye containing Ehronl obtained in this way forms a blackish powder. whose aqueous solutions appear blue in a thin layer and purple in a thicker layer. For dyes wool from an acid bath in green shades with excellent lightness properties.
