Fibre-reactive anthraquinone dyestuffs are disclosed which are of the formula ##STR1## wherein X and Y represent independently of each other hydrogen or SO.sub.3.sup.- M.sup.+, Z represents a fibre-reactive radical bound to -NH- directly or via a bridging member selected from carbonyl, sulphonyl or carbonylimino; and forming with the substrate especially polyamide or cellulose at least one covalent bond, and M.sup.+ represents one equivalent of a colorless cation. These dyestuffs are useful for the pad-dyeing and printing of organic materials, especially materials made from polyamide or cellulose. The resulting dyeings are distinguished by excellent fastness to wet processing such as, in particular to washing, water, perspiration, alkali and rubbing, as well as by a good fastness to light.
本发明揭示了一种纤维反应性蒽醌染料,其化学式为##STR1##其中X和Y分别独立地表示氢或SO.sub.3.sup.-M.sup.+,Z表示与基质(尤其是聚酰胺或纤维素)直接或通过选择的桥接成员(包括羰基,磺酰基或羰基亚胺)结合的纤维反应性基团,形成至少一种共价键,M.sup.+表示一当量无色阳离子。这些染料适用于有机材料的垫染和印花,尤其是聚酰胺或纤维素制成的材料。由此产生的染色具有良好的耐湿加工性,特别是耐洗涤,耐水,耐汗液,耐碱和耐摩擦性,以及良好的耐光性。
