Abstract:
Trifunctional reactive dyestuffs of the formula ##STR1## a process for their preparation and their use, wherein D=the radical of a diazo component of the benzene or naphthalene series,K=the radical of a coupling component of the formula ##STR2## where the radical of the formula II and the azo group are linked to one another via the bond marked with *,X=a radical of the formula ##STR3## Z=a heterocyclic fibre-reactive radical which differs from X and the other substituents have the meaning given in the description.
