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 dyestuff mixtures containing one or more monochlorotriazine dyestuffs of the formula (1) ##STR1## and one or more monofluorotriazine dyestuffs of the formula (2) ##STR2## in which the substituents have the meaning given in the description, show on-tone exhaustion onto fibres and are fixed uniformly even under different fixation conditions.

Bifunctional reactive dyestuff mixture

Reactive dyestuffs which, as the free acid, have the following formula ##STR1## in which K is ##STR2## the bonding to the triazinyl radical taking place in each case via the amino function of K, and the remaining substituents have the meaning given in the description, are suitable in particular for the dyeing and printing of natural and synthetic OH- and/or amido-containing materials.

Azo dyestuffs containing fluorotriazinyl and vinylsulfonylmethyl-type

Reactive dyestuffs have the following formula ##STR1## in which D is the radical of an organic dyestuff B is a direct bond or a bridging member on a ring C atom of an aromatic-carbocyclic or on a ring C atom or N atom of an aromatic-heterocyclic ring in D, R.sub.a, R.sub.b, identical or different, are H, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkyl substituted by OH, CN, CO.sub.2 H, OSO.sub.3 H or SO.sub.3 H, U is Cl, F or a pyridinium radical which is unsubstituted or substituted by CO.sub.2 H, CONH.sub.2, SO.sub.3 H or C.sub.1 -C.sub.4 -alkyl, W is straight-chain or branched C.sub.1 -C.sub.6 -alkylene, Y is CH.dbd.CH.sub.2 or CH.sub.2 --CH.sub.2 --X, in which X is a radical which can be eliminated by alkali, V is H, halogen, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.3 -alkyl, CN, COOH, CONH.sub.2, SO.sub.3 H.
