Water-soluble copper formazan compounds of the general formula ##STR1## in which: Y is vinyl or ethyl which is substituted by a substituent eliminatable under alkaline conditions; the benzene nucleus A can be substituted by further substituents; M is hydrogen or a metal; B is substituted or unsubstituted phenylene or naphthylene; Z.sup.1 is hydrogen or a water-solubilizing group, or --B--Z.sup.1 together denote hydrogen, carboxy, cyano or nitro; D is a substituted or unsubstituted benzene or naphthalene radical; and R is hydrogen or a group of the formula ##STR2## in which R* is hydrogen or a substituted or unsubstituted lower alkyl, n denotes the number zero or 1, and Y.sup.2 is defined in the same manner as Y. These copper formazan compounds possess fiber-reactive dye properties and dye particular cellulose fiber materials in deep reddish blue to greenish blue fast shades.
