Reactive azo dyestuffs, free from anionic groups and containing a basic group and halogenotriazinyl radical and useful for dyeing cellulose/polyester

摘要

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 in which D is the radical of an organic azo dyestuff which is free from anionic groups and is preferably free from basic groups, B is a direct bond or a bridge member to a ring C atom of D, R1 is H, alkyl, aralkyl or aryl and W is a halogenotriazinyl radical containing a basic group; the dyestuffs are useful for the dyeing and printing of fibre materials containing cellulose.
