    • Copper complex formazan compounds useful as dyestuffs and having fiber-reactive dyestuff properties, which are capable of providing fast, deep dyeings and prints on fiber materials, preferably of cellulose and polyamide fibers, have the following structural formula ##STR1## in which m and n are 1 or 2, A is a benzene ring or a naphthalene ring, either of which is necessarily substituted by the sulfo group in the ortho-position relative to the N-atom and which can optionally be further substituted with one to three substituents; B is phenyl or naphthyl, either of which can be substituted or unsubstituted;M is hydrogen or one equivalent of a metal;X is hydrogen or sulfo;Z is hydrogen or a group which confers water-solubility, one or both of which--besides the sulfo group necessarily required in the o-position relative to the N-atom of the hydrazone component A--are bonded to A on an aliphatic or aromatic carbon atom,Z.sup.1 is hydrogen or a group which confers water-solubility, one or both of which are bonded to B on an aliphatic or aromatic carbon atom of B, Z and Z.sup.1 together denoting not more than three sulfo groups if X is a sulfo group, and Y is the vinyl group or a group of the formula --CH.sub.2 --CH.sub.2 --E, in which E represents a substituent which can be removed under alkaline conditions.
    • 可用作染料并具有纤维活性染料性质的铜复合甲an化合物能够在纤维材料(优选纤维素和聚酰胺纤维)上提供快速,深色的染色和印花,具有以下结构式:其中m和n 是1或2,A是苯环或萘环,其中任一个必须被相对于N-原子的邻位的磺基取代,并且可以任选地被一至三个取代基进一步取代; B是苯基或萘基,其中任一个可以是取代或未取代的; M是氢或1当量的金属; X是氢或磺基; Z是氢或赋予水溶性的基团,除了在相对于腙组分A的N-原子的o位置必需的磺基基团之外,其中一个或两个与在脂肪族或芳香族基团上的A键合 碳原子,Z1是氢或赋予水溶性的基团,其中一个或两个键合到B上的B,Z和Z1的脂族或芳族碳原子上,如果X是磺基,则表示不超过三个磺基 并且Y是乙烯基或式-CH 2 -CH 2 -E的基团,其中E表示可在碱性条件下除去的取代基。
