Dyestuffs are disclosed having the formula ##STR1## in which W is a reactive radical; D is the radical of an organic dyestuff; X.sub.1 is hydrogen or alkyl; X.sub.2 and X.sub.3 are hydrogen, alkyl, cycloalkyl, aralkyl or aryl; or X.sub.2 and X.sub.3 together are alkylene; Alkylene is C.sub.1 -C.sub.6 -alkylene or cycloalkylene; and n is 0 or 1. The dyestuffs are used in the dyeing of textile materials containing hydroxyl groups and nitrogen, especially natural and regenerated cellulose, wool, silk, synthetic polyamide fibers and synthetic polyurethane. The dyeings obtained are, in general, distinguished by good to very good fastness properties, especially by excellent wet fastness.
染料的公式为##STR1##,其中W是一个反应性基团;D是一个有机染料的基团;X.sub.1是氢或烷基;X.sub.2和X.sub.3是氢、烷基、环烷基、芳基或芳基烷基;或者X.sub.2和X.sub.3组合在一起是亚烷基;亚烷基是C.sub.1-C.sub.6-亚烷基或环烷基;n为0或1。这些染料用于染色含有羟基和氮的纺织材料,特别是天然和再生纤维素、羊毛、丝绸、合成聚酰胺纤维和合成聚氨酯。一般来说,所获得的染色品具有良好到非常好的耐久性,特别是在潮湿条件下具有优异的耐久性。
