Abstract

The invention comprises a process for the reduction of sulphur dyes in which an alkali metal borohydride is used in conjunction with sodium sulphide or hydrosulphide in alkaline solution. The reduction may be effected using dyes which are soluble or insoluble in water to produce a dye composition in the liquid form. Alternatively the dyestuff may be reduced to the substantive form in the presence of a cellulosic material to be dyed. The preferred borohydrides are those of sodium and potassium and are used as 0.01% to 1% preferably 0.1 to 0.6% based on the weight of sulphur dye to be reduced. The temperature of reduction is from room temperature to 230 DEG F. at pH usually above 9.5.
