Abstract
Fiber-reactive dyestuffs, processes for their preparation and their use Dyestuffs of the formula (1) are described ##STR1## The dyestuffs have fiber-reactive properties and dye materials containing hydroxy groups and/or containing carboxamide groups, in particular fiber materials, such as, for example, cellulose fibers, wool and synthetic polyamide fibers, in deep, fast shades by the methods known for this process.

A dyestuff corresponding to the formula F--Z, in which
- F is the radical of a mono-, dis- or polyazo dye-stuff containing sulfo groups or of a heavy metal complex mono-, dis- or trisazo dyestuff, or of an anthraquinone, phthalocyanine, formazan, azomethine, nitroaryl, dioxazine, phenazine or stilbene dyestuff and
- Z is a group of the formula (2) ##STR47## in which R.sup.x is hydrogen or alkyl having 1 to 4 carbon atoms, and in which --N(R.sup.x)-- is optionally part of a saturated heterocyclic radical,
- R.sup.y is hydrogen or alkyl having 1 to 4 carbon atoms, R.sup.z is hydrogen,
- Q is phenylene, which can be substituted by 1 or 2 of the following substituents;
- alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, nitro, hydroxy, carboxy or sulfo, or is naphthylene, which can be substituted by 1, 2 or 3 sulfo groups, or Q is alkylene having 1 to 6 carbon atoms, or is alkylene having 2 to 8 carbon atoms, which is interrupted by 1 or 2 hetero groups, or Q is alkylene-A-phenylene, phenylene-A-alkylene, alkylene-A-phenylene-A-alkylene, phenylene-A-alkylene-phenylene or phenylene-A-phenylene, in which each phenylene independently of one another is phenylene which is optionally substituted by 1 or 2 of the following substituents:
- from the alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, nitro, hydroxy, carboxy or sulfo, each alkylene independently of one another is alkylene having 1 to 6 carbon atoms or alkylene having 2 to 8 carbon atoms, which is interrupted by 1 or 2 hetero groups, and each A independently of one another is a direct bond or a hetero group of the formulae --O--, --SO.sub.2 --, --CO--, --NH--, --CO--NH--, --NH--CO--, --SO.sub.2 --NH--, --NH--SO.sub.2 --, --SO.sub.2 -- or --N(R)--, in which R is alkyl having 1 to 4 carbon atoms,
- which is optionally substituted by hydroxy, sulfato, phosphato, sulfo or acetyloxy, or is propionyl or acetyl, or
- z is the number zero or 1,
- y is the number 1 or 2, and y is 1 if z is 1,
- Y is vinylsulfonyl, .beta.-chloroethylsulfonyl, .beta.-phosphatoethylsulfonyl or .beta.-sulfatoethylsulfonyl,
- Hal is chlorine or fluorine and
- X.sup.0, is chlorine or fluorine.
