Reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein D is the radical of an organic dyestuff of the mono-azo, polyazo or metal complex azo series and the other substituents have the meaning given in the description, show improved application properties.

Compounds useful for the preparation of bi-and polyfunctional reactive

Reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein D is the radical of an organic dyestuff of the monoazo, polyazo or metal complex azo series and the other substituents have the meaning given in the description, show improved application properties.

Bi -and polyfunctional reactive dyestuffs, their prepartion and their use

Reactive dyestuffs of the formula ##STR1## in which Z is a cyano-free pyrimidine reactive group and the remaining groups have the meaning given in the description, are highly suitable for the dyeing and printing of hydroxyl- or amido-containing materials.

Reactive dyestuffs having reactive fluorine-containing pyrimidyl radicals

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,

Azo dyestuffs carrying sulphonylated amino-halo-triazinyl reactive site
