Abstract
Abstract Dyestuffs are disclosed having the formula ##STR1## in which W is a reactive radical; D is the radical of an organic dyestuff; X 1 is hydrogen or alkyl; X 2 and X 3 are hydrogen, alkyl, cycloalkyl, aralkyl or aryl; or X 2 and X 3 together are alkylene; Alkylene is C 1 -C 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.
