    Abstract: The invention comprises dyes of the formula wherein X is amino, or alkylamino; Y is hydrogen, amino, alkylamino, hydroxy, piperidinyl or alkylmercapto; Z is a linear or branched chain alkyl of up to 8 carbon atoms which may bear alkoxy, cyano, unsubstituted or substituted carbamoyl or carbalkoxy groups, or denotes an aralkyl radical or the propinyl group. The compounds are prepared by reacting a carboxylic hydrazide of the formula where Z11 is No2 or as Y, either with CS2 in a alkaline reacting agent, and simultaneously or subsequently reacting with an alkylating agent which yields Z, or with a mercapto formamide chloride of the formula where R1 and R2 are substituted or unsubstitute alkyl or aryl radicals or together with the nitrogen form a piperidinyl or morpholino ring, and subsequently reducing the nitro group to an amino group. The mercapto formamide chloride may be formed in situ by treating a dithiocarbamic ester of the formula with chlorinating agents.
