Water-soluble monoazo compounds according to the general formula (1) below having valuable fiber-reactive dyestuff properties which dye carboxamido- and/or hydroxy-containing materials, in particular cellulose fibers, in fast yellow to orange hues. ##STR1## in which the symbols denote: M is hydrogen or an alkali metal, R.sup.1 is hydrogen, methyl, ethyl, methoxy, ethoxy, chlorine, bromine, carboxy or sulfo, R.sup.2 is hydrogen, methyl, ethyl, methoxy, ethoxy, chlorine, or bromine, R is carboxy or lower carbalkoxy, n is the number zero or 1, X and Y independently of each other are each .beta.-thiosulfatoethyl or .beta.-sulfatoethyl or vinyl, however, in the case of X and/or Y being equal to vinyl the index n must be 1.
根据以下一般公式(1)的水溶性单偶氮化合物具有有价值的纤维反应性染料特性,可染色含有羧胺基和/或羟基的材料,特别是纤维素纤维,呈现快速的黄色至橙色色调。其中符号表示:M为氢或碱金属,R.sup.1为氢、甲基、乙基、甲氧基、乙氧基、氯、溴、羧基或磺基,R.sup.2为氢、甲基、乙基、甲氧基、乙氧基、氯或溴,R为羧基或较低的羧酰氧基,n为数值零或1,X和Y彼此独立地为β-硫代磺酸乙基、β-磺酸乙基或乙烯基,但是如果X和/或Y等于乙烯基,则指数n必须为1。
