DESCRIPTION:
BRIEF SUMMARY
The invention relates to the technical field of fiber-reactive dyestuffs.
The practice of dyeing using reactive dyestuffs has recently led to increased requirements being imposed on the quality of the dyeings and the efficiency of the dyeing process. There consequently continues to be a need for novel reactive dyestuffs which have improved properties, not only in respect of the fastnesses but also in respect of a high degree of fixing on the material to be dyed.
Fiber-reactive dyestuffs which contain an s-triazine radical to which a fiber-reactive group from the vinylsulfone series is bonded and in which the third substituent is an optionally substituted amino group or a methoxy group are thus known from U.S. Pat. No. 4,740,592 and from the Japanese Patent publications Sho-40-17113 and Sho-50-31566. Dyestuffs which contain a 2-chloro-4-cyanamido-s-triazin-6-ylamino radical are furthermore known from U.S. Pat. No. 3,758,470. However, the known dyestuffs have certain technological deficiencies; thus, they have a degree of fixing which is no longer completely satisfactory from today's standpoint, and they produce dyeings which do not have an adequate coloristic depth of color.
Novel water-soluble dyestuffs which have been improved in this respect have now been discovered with the present invention, these dyestuffs corresponding to the following formula (1) ##STR3## In formula (1): F is the radical of a monoazo, disazo or polyazo dyestuff or of a heavy metal complex azo dyestuff derived therefrom, or of an anthraquinone, phthalocyanine, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthene, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dyestuff; such as the methyl or ethyl group, which can be substituted by halogen, such as chlorine and bromine, hydroxyl, cyano, alkoxy having 1 to 4 carbon atoms, such as methoxy and ethoxy, alkoxycarbonyl having 2 to 5 carbon atoms, carboxyl, sulfamoyl, sulfo or sulfato, preferably the methyl or ethyl group and in particular a hydrogen atom; ##STR4## in which R.sup.z is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, such as, in particular, the methyl or ethyl group, which can be substituted by halogen, such as chlorine and bromine, hydroxyl, cyano, alkoxy having 1 to 4 carbon atoms, such as methoxy and ethoxy, carboxyl, sulfamoyl, sulfo or sulfato or by a phenyl radical which is optionally substituted by substituents from the group comprising halogen, such as chlorine and bromine, alkoxy having 1 to 4 carbon atoms, such as methoxy and ethoxy, alkyl having 1 to 4 carbon atoms, such as methyl, sulfo and carboxyl, or is a cyclohexyl radical or a phenyl radical which is optionally substituted by substituents from the group comprising halogen, such as chlorine and bromine, alkoxy having 1 to 4 carbon atoms, such as methoxy and ethoxy, alkyl having 1 to 4 carbon atoms, such as methyl, sulfo and carboxyl, arylene-alkylene or alkylene-arylene-alkylene or arylene-alkylene-arylene radical, in which the alkylene radicals are those having 1 to 8, preferably 2 to 6 and in particular 2 to 4, carbon atoms and can be substituted and the arylene radicals are optionally substituted phenylene or naphthylene radicals, and in which the alkylene radicals can be interrupted by 1 or more, such as 1 or 2, hetero groups, such as amino groups, or oxygen or sulfur atoms or groups of the formulae --SO.sub.2 --, --CO--, --SO.sub.2 --NH-- or --CO--NH--, and the alkylene and arylene portions in the combined alkylene/arylene radicals can in each case be separated from one another by such a group, .beta.-phosphatoethyl group or a .beta.-alkanoyloxy-ethyl group having 2 to 5 carbon atoms in the alkanoyl radical, such as the .beta.-acetoxyethyl group, or the .beta.-benzoyloxy-ethyl, .beta.-(sulfobenzoyloxy)-ethyl or .beta.-(p-toluenesulfonyloxy)-ethyl group or a .beta.-haloethyl group, such as the .beta.-bromoethyl or .beta.-chloroethyl group, preferably the vinyl group and in particular the .beta.sulfatoethyl group, where B is 2, the groups of t
