ABSTRACT:
Reactive dyestuffs of the formula ##STR1## in which D is the residue of an organic dyestuff, R is hydrogen or a lower alkyl, R.sub.1 is hydrogen or a substituent, R.sub.2 is hydrogen, halogen, substituted or unsubstituted alkyl, alkenyl, aralkyl or aryl radical, carboxylic acid ester radical, carboxylic acid amide radical, alkylsulphone, or arylsulphone; and F is fluoro; and process for the preparation of such dyestuffs. These dyestuffs are particularly useful in dyeing materials containing hydroxyl groups and nitrogen, e.g. regenerated cellulose, wool, silk, synthetic polyamide, and polyurethane which dyeings possess excellent fastness to wet processing and good fastness to washing, milling and potting on wool.
