摘要:
Copper formazan reactive dyes of the formula: ##STR1## where X is cyano, halogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, one of two radicals Y and Z is hydrogen and the other is hydroxysulfonyl, R.sup.1 is hydrogen, C.sub.1 -C.sub.4 -alkyl or cyano- or carbamoyl-substituted C.sub.2 -C.sub.4 -alkyl and R.sup.2 is fluorine or chlorine, and salts thereof are useful for dyeing cellulose fibers, resulting in blue shades. Such dyes are soluble in water and have a high fastness level and tinctorial strength.
