Fibre-reactive dyestuffs

Fiber-reactive monoazo and disazo compounds of the formula

Fibre-reactive azo dyestuffs containing a halo substituted pyrimidine

Fiber-reactive disazo dyes correspond to formula I, ##STR1## and they are present as free acids or in salt form. They are used as reactive dyes for dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates, especially leather or fibrous material, which consists of or contains natural or synthetic polyamides or natural or regenerated cellulose. The dyeings obtained have high fixation values and good light fastness.

Reactive disazo dyestuff compounds containing halo-substituted triazinyl

Compounds of the formula ##STR1## and salts thereof, wherein each

Substituted 5-�5'-�(5'- Chloro-2', 4'-difluoropyrimid-6'-ylamino)

Dyes containing 5-cyano-2,4 or 4,6-dichloropyrimidyl fiber-reactive

Compounds of the formula ##STR1## and salts thereof, and mixtures of such compounds and salts, wherein F.sub.c is ##STR2## wherein D.sub.1 is an unsubstituted or substituted phenyl or naphthyl diazo component radical,

Monoazo and disazo compounds having 5-cyano-2,4-and

Compounds of the formula ##STR1## and salts thereof, wherein R.sub.1 is hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkoxy,

Metal-free compounds of the formula ##STR1## a 1:1 or 1:2 metal complex of a metallizable compound of said formula or a salt of a metal-free compound of said formula or of a 1:1 or 1:2 metal complex thereof each cation of which is independently a non-chromophoric cation, or a mixture, thereof, wherein

Dyes having one or two 2,4- or 4,6-dichloro-5-cyanopyrimidyl groups

Complexes of the formula ##STR1## and salts thereof, wherein

Copper complexes of disazo compounds having di- or tri- sulfonaphthol

Complexes of the formula ##STR1## or a water-soluble salt thereof each cation of which is independently a non-chromophoric cation, wherein X is chloro or hydroxy,

Mixtures of copper complexes of disazo compounds:

Metal-free azo compounds of the formula ##STR1## wherein Ra is an aromatic group or an active methylene coupling component radical as defined in the specification,
