    • The present invention relates to reactive dye-compounds of formula I, ##STR1## in which Y is hydrogen or sulpho,X is a straight chain or branched (C.sub.2-6) alkylene group or ##STR2## in which each of A.sub.1 and A.sub.2, independently, is a direct bond or a (C.sub.1-4) alkylene group, n is 1 or 2 and the ring D is optionally substituted by up to three (C.sub.1-4) alkyl groups,with the proviso that when n is 2, the group ##STR3## is the radical of an unsymmetrical diamine, R.sub.1 is hydrogen; (C.sub.1-4) alkyl; (C.sub.2-4) alkyl substituted in the .beta.,.gamma.-or .delta.-position by hydroxy and/or carboxy; or (C.sub.5-6) cycloalkyl or (C.sub.1-4) alkyl-substituted (C.sub.5-6) cycloalkylZ is the radical of a fibre reactive group which contains a single fibre reactive componentor mixtures thereof, which compounds are in free acid or water-soluble salt form and are useful as dyestuffs for dyeing or printing hydroxy group-containing or nitrogen containing organic textile substrates.
    • 本发明涉及式I的活性染料化合物,其中Y为氢或磺基,X为直链或支链(C2-6)亚烷基或“IMAGE”,其中A1和A2各自为 独立地是直接键或(C 1-4)亚烷基,n是1或2,并且环D任选被至多三个(C 1-4)烷基取代,条件是当n是2时, 该组是不对称二胺的基团,R1是氢; (C 1-4)烷基; 被羟基和/或羧基取代的β-,γ-或δ-位的(C2-4)烷基; 或(C 5-6)环烷基或(C 1-4)烷基取代的(C 5-6)环烷基Z是含有单纤维反应性组分或其混合物的纤维反应性基团的基团,该化合物在游离酸或水 可溶性盐形式,可用作染色或印刷含羟基或含氮有机织物基材的染料。
