Water-soluble fibre-reactive dyes, process for their preparation, and their use

摘要

A description is given of dyes which contain one or two fibre-reactive radicals of the general formula <IMAGE> and also of the novel amino compounds of the formula HN(R DEG )-(CH2)3-SO2-Y<1>, which are used as intermediate. In these formulae, R<A> is hydrogen or lower alkyl which may be substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkoxycarbonyl, carboxyl, sulphamoyl, sulpho, sulphato or phosphato; R is alkyl of 1 to 6 carbon atoms which may be substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkoxycarbonyl, carboxyl, sulphamoyl, sulpho, sulphato, phosphato, phenyl or sulphophenyl, or is phenyl which may be substituted by halogen, lower alkyl, lower alkoxy, sulpho and/or carboxyl; X is halogen, cyanoamino, methylsulphonylamino, ethylsulphonylamino, carboxypyridyl, aminocarbonylpyridyl, or a group of the formula -N(R)-W-(SO2-Y)z where R, W, X and z are as defined above or below; W is alkylene with 3 to 8 carbon atoms which may be substituted by alkoxy, halogen, alkoxycarbonyl, carboxyl, sulpho and/or sulphato or by a phenyl radical which is itself optionally substituted by sulpho, carboxyl, methoxy, ethoxy and/or methyl, or W may be alkylene substituted by such an optionally substituted phenyl radical and by a sulpho, sulphato or carboxyl group, or by a heterocyclic radical; Y is vinyl, beta -sulphatoethyl, beta -thiosulphatoethyl, beta -phosphatoethyl, beta -alkanoyloxyethyl, beta -sulphobenzoyloxyethyl,...
