Process for the production of 2,5-diamino-6-nitro-pyridine derivatives, their use in hair dye compositions and new 2,5-diamino-6-nitropyridine derivatives

A process for producing 2,5-diamino-6-nitropyridine derivatives having the general formula (I) STR1 wherein R1 to R4 represent hydrogen or the radicals alkyl, hydroxy alkyl, dihydroxy alkyl, alkoxy alkyl, alkoxy carbonyl, hydroxy- or chlorine-substituted alkoxy carbonyl, aminoalkyl and aminoalkyl substituted by alkyl or hydroxy alkyl groups, the alkyl groups in each case containing 1 to 4 carbon atoms or an oxazolidinone ring being formed by R1 and R2 and/or R3 and R4. The present invention also relates to novel 2,5-diamino-6-nitropyridine derivatives and to a hair dyeing agent containing 2,5-diamino-6-nitropyridine derivatives, which are direct nitro dyes coloring the hair yellow orange to blue violet and are physiologically harmless.
