Abstract

The invention is directed to reactive azo dyestuffs, free from anionic groups and which contain a basic group and a halogenotriazinyl radical and are of the general formula ##STR1## in which D is the radical of an organic azo dyestuff which is free from anionic groups and is preferably free from basic groups, PA1 B is a direct bond or a bridge member to a ring C atom of D, PA1 R.sub.1 is H, alkyl, aralkyl or aryl and PA1 W is a halogenotriazinyl radical containing a basic group; the dyestuffs are useful for the dyeing and printing of fibre materials containing cellulose.
