Abstract: The black water-soluble sulphur dyes of the formula in which e.g. F is the dye chromophore of C.I. Leuco Sulphur Black 1, R is hydrogen or alkyl, M is an alkali metal cation, and n is a number such that the dye contains from 5 to 20% by weight of COO groups, are outstandingly suitable, inter alia, for the production of recording fluids.
