    • Copper complex formazan compounds of the general formula (1) ##STR1## in which A and B both independently of one another denote a benzene or naphthalene ring, both of which can be substituted by substitutents customary in fiber-reactive dyestuffs, these substituents being, in particular, the groups Z which confer water-solubility and fiber-reactive groups --SO.sub.2 --Y shown in formula (1);Z is a group which confers water-solubility, such as a carboxy of sulfo group, and can be bonded to A, B and R;m is the number 1, 2, 3 or 4;R is an aryl radical, for example phenyl or naphthyl, which can be substituted by one or two groups Z of the above meaning and/or by halogen, lower alkyl and/or lower alkoxy, or is a lower alkyl radical, which can be substituted by halogen, sulfo and/or carboxy;the group --SO.sub.2 --Y can be bonded to A and B;n is the number 1 or 2;Y is vinyl or an ethyl group, which is substituted in the .beta.-position by a substituent which can be eliminated by alkali;X is an oxygen atom or a carbonyloxy or sulfo group;M is hydrogen or a salt-forming metal, such as an alkali metal.The copper complex formazan compounds of the formula (1) are particularly suitable as fiber-reactive dyestuffs for dyeing materials containing hydroxy groups and/or carboxamide groups, such as, for example, wool and synthetic polyamide fiber materials, and in particular cellulose fiber materials, such as cotton, which they dye in deep fast shades.
    • 通式(1)其中A和B彼此独立地表示苯基或萘环的通式(1)的复合化合物甲并咪唑化合物,它们都可以被纤维反应性染料中常规的取代基取代, 取代基特别是赋予式(1)所示的水溶性基团和纤维反应性基团-SO 2-Y的基团Z; Z是赋予水溶性的基团,例如磺基的羧基,并且可以与A,B和R键合; m是数字1,2,3或4; R是芳基,例如苯基或萘基,其可以被一个或两个上述含义的基团Z和/或被卤素,低级烷基和/或低级烷氧基取代,或者是低级烷基,其可以是 被卤素,磺基和/或羧基取代; 基团-SO 2 -Y可以键合到A和B上; n是数字1或2; Y是乙烯基或乙基,其在β-位中被可被碱去除的取代基取代; X是氧原子或羰基氧基或磺基; M是氢或成盐金属,例如碱金属。 式(1)的铜络合物甲脒化合物特别适用于用于染色含有羟基和/或羧酰胺基团的材料的纤维反应性染料,例如羊毛和合成聚酰胺纤维材料,特别是纤维素纤维材料 ,如棉花,它们以深色色调染色。
