    • Optionally metallized azo dyestuffs which in the form of the free acid correspond to the formula ##STR1## wherein K is the radical of a benzene, naphthalene, pyrazolone, pyridone, pyrimidone, acetoacetic acid arylide or aminopyrazole coupling component;A is a non-ionic substituent;X is ##STR2## wherein W is a direct bond or a bridge member to a C atom of the benzene or naphthalene nucleus or the coupling component K;R is hydrogen or C.sub.1 -C.sub.4 -alkyl;B is a direct bond or a bridge member, especially -CO- or -SO.sub.2 -, to a C atom of Q;Q is a reactive radical;m is 0, 1 or 2;n is 0, 1 or 2;p is 0 or 1;q is 0, 1 or 2; andr is 0 or 1;and their use for the dyeing and printing of natural and regenerated cellulose fibre materials such as cotton and rayon, as well as natural and synthetic polyamide fibre materials, for example those of wool, silk, poly-.epsilon.-caprolactam or polycondensate of hexamethylene-diamine and adipic acid. The dyeings obtained, espeically those on cotton and rayon, are distinguished by good fastness properties, especially fastness to wet processing and to light.
    • 任选的以游离酸形式的金属化偶氮染料对应于下式:其中K是苯,萘,吡唑啉酮,吡啶酮,嘧啶酮,乙酰乙酸芳基化物或氨基吡唑偶联组分的基团; A是非离子取代基; X是其中W是苯或萘核的C原子或偶联组分K的直接键或桥键元素; R是氢或C 1 -C 4 - 烷基; B是Q的C原子的直接键或桥结构,特别是-CO-或-SO 2 - ; Q是反应性基团; m为0,1或2; n为0,1或2; p为0或1; q是0,1或2; r为0或1; 以及它们用于天然和再生纤维素纤维材料如棉和人造丝的染色和印花,以及天然和合成的聚酰胺纤维材料,例如羊毛,丝绸,聚ε-己内酰胺或六亚甲基二胺的缩聚物 和己二酸。 获得的染色,特别是在棉和人造丝上的染色,具有良好的牢度特性,特别是湿法加工和光照牢度的区别。
