Abstract:
NITROAZO DYESTUFFS OF THE FORMULA
2-((X,Y-PHENYL)-NH-(2-NO2-1,4-PHENYLENE)-N=N-),
4-R,Z-PHENOL
IN WHICH X AND Y ARE EACH HYDROGEN, CHLORO, LOWER ALKYL, LOWER HYDROXYALKYL, LOWER ALKOXY, LOWER HYDROXYALKOXY PHENOXY, PHENYL-LOWER ALKOXY, LOWER ALKYLMERCAPTO, PHENYLMERCAPTO, OR LOWER ALKANOYLAMINO, R IS CHLORO, BROMO, LOWER ALKYL, CYCLOHEXYL, PHENYL, B-CYANOETHYL OR LOWER ALKOXY AND Z IS HYDROGEN OR LOWER ALKYL. THE NEW DYESTUFFS ARE USEFUL FOR DYEING CELLULOSE ACETATE, CELLULOSE TRIACETATE, POLYAMIDE AND ESPECIALLY POLYESTER FIBERS, ON WHICH THEY YIELD YELLOW TO ORANGE SHADES OF EXCELLENT FASTNESS PROPERTIES.
