Dye mixture containing at least four diazo dyes having the same color

Process of preparing diaminopyridine compounds

Dye mixtures comprising at least six isochromatic dyes of the formula ##STR1## where D is the radical of a diazo component of the aniline, aminothiophene, aminothiazole, aminoisothiazole or aminobenzisothiazole series and

Dye mixtures containing azo dyes having a coupling component from the

Dye mixtures comprising at least six isochromatic dyes of the formula ##STR1## where D is the radical of a diazo component of the aniline, aminothiophene, aminothiazole, aminoisothiazole or aminobenzisothiazole series and one of the radicals X.sup.1 and X.sup.2 is amino and the other is a radical of the formula ##STR2## where L is unsubstituted or substituted C.sub.2 -C.sub.8 -alkylene

The compounds of the general formula I ##STR1## where X is fluorine, chlorine, bromine, SO.sub.2 E or unsubstituted or substituted hydroxyl or mercapto, E is alkyl, alkenyl, cycloalkyl, aralkyl, aryl, chlorine or unsubstituted or substituted hydroxyl or amino, Y is cyano, nitro, alkanoyl, aroyl, alkylsulfonyl, arylsulfonyl, carboxyl, a carboxylic ester group or unsubstituted or substituted carbamyl, T is hydrogen, C.sub.1 -C.sub.4 -alkyl, a radical which can be introduced by electrophilic substitution or a radical of the formula --CH.dbd.B, in which B is a radical of a methylene-active compound or of an amine, and K is a radical of a coupling component, are very useful for dyeing synthetic fibers or plastics.

Dyes containing thiophene radicals

Azo dyes having the formula ##STR1## wherein the substituents are as defined in the specification and are useful for dyeing or printing textile materials.

Thiopheneazo dyes with a coupling component of the diaminopyridine series

The compounds of the general formula ##STR1## where X is fluorine, chlorine, bromine, SO.sub.2 E or unsubstituted or substituted hydroxyl or mercapto, E is alkyl, alkenyl, cycloalkyl, aralkyl, aryl, chlorine or unsubstituted or substituted hydroxyl or amino, Y is cyano, nitro, alkanoyl, aroyl, alkylsulfonyl, arylsulfonyl, carboxyl, a carboxylic ester group or unsubstituted or substituted carbamyl, T is hydrogen, C.sub.1 -C.sub.4 -alkyl, a radical which can be introduced by electrophilic substitution or a radical of the formula --CH.dbd.B, in which B is a radical of a methylene-active compound or of an amine, and K is a radical of a coupling component, are very useful for dyeing synthetic fibers or plastics.
