- 4-Halogeno-s-triazin-2-yl-phosphoramide acid containing reactive dyestuffs
-
Reactive dyestuffs of the formula STR1 WHEREIN STR2 IS AN AMINO-SUBSTITUTED AZO DYESTUFF RADICAL WHERE B is the azo dyestuff radical thereof; R is hydrogen or lower alkyl which is unsubstituted or substituted by methoxy, ethoxy or hydroxy; m is 1-2; And wherein Y is STR3 where X is chloro, bromo or fluoro; Z is STR4 where EACH M+ is alkali metal or ammonium, or both M+ together represent magnesium, calcium or zinc; and R' is hydrogen, lower alkyl or lower alkyl substituted by methoxy, ethoxy or hydroxy. These dyestuffs are useful in dyeing textile materials of cotton, regenerated cellulose, wool, silk, cellulose acetate, polyamides, polyacrylonitrile and modified polyacrylonitrile.
