    Abstract: The invention comprises water-soluble dyes of the formula where F is the radical of a dioxazine, triphenyl-methane, phthalocyanine or nitro dye, R is hydrogen or a hydrocarbon radical, A is an alkylene radical or an arylene-alkylene, arylene-sulphonylamino-alkylene or arylene-carbonyl-amino-alkylene radical in which the arylene group is attached to the nitrogen atom and the alkylene group to the -SSO3Me group, the aromatic nucleus of which may contain alkyl or alkoxy groups or halogen atoms, Z is -SO2- or -CO-, Me is an alkali metal ion or ammonium and n is 1, 2, 3 or 4 and which dyes may contain further groups imparting solubility in water. The invention further comprises a process for making the above dyes and dyes of the above formula where F is an anthraquinone or azo dye radical and A, R, Me, Z and n are as above, by condensing an amine of the formula with a dye of the formula wherein F is the radical of a dye mentioned above, Z and n are as above and the halogen atom is capable of reacting with the amine defined above, in an aqueous or non-aqueous medium in the presence of an acid-binding agent at a temperature from about 0 DEG to 60 DEG C. at a pH of about 7 to 10 and the dye-stuff is then precipitated as an alkali metal or ammonium salt. Examples are given. The dyes dye wool, silk, polyamides and polyurethanes from an acid bath.
