ABSTRACT:
Reactive dyestuffs of the formula ##STR1## in which D is the radical of an organic dyestuff, e.g. an azo dyestuff; R is hydrogen or lower alkyl; O is a bridge member, e.g. --SO.sub.2 --; n is the number 0 or 1; R.sub.1 is hydrogen or a substituent; R.sub.2 is hydrogen, optionaly substituted alkyl, alkenyl, aralkyl or aryl; and F is fluoro; are disclosed. These dyestuffs are suitable for dyeing textile materials containing hydroxyl groups or nitrogen, e.g. cellulose and wool. The dyeings have excellent fastness properties especially wet processing fastness.
