Beschreibung
Zusammenfassung:	The invention relates to a process for the trichromatic dyeing or printing of natural and synthetic polyamide materials with dye mixtures, in which process there is used the dye of the formula (1) wherein R1 is methyl or ethyl, and R2 is cyclohexyl or phenyl, together with at least one dye of the formula (2) wherein B1, B2 and E1 are hydrogen, C1-C4-alkyl or C1-C4-alkoxy, and X is straight-chain or branched-chain C1-C4-alkyl, or straight-chain or branched-chain C2-C4-hydroxyalkyl, and a dye of the formula (3) wherein one Y is hydrogen or methyl, and the other Y is C2-C4-alkanoylamino or C2-C4-hydroxyalkylsulfamoyl, or with a mixture of the dyes of the formulae (4) and (5) where Y1 in the formula (4) is C2-C4-hydroxyalkylsulfamoyl, and Z is hydrogen or methyl, and Y2 in the formula (5) is C2-C4-alkanoylamino, Z in the formula (4) being hydrogen when Y2 in the formula (5) is the propionyl amino group in the m-position with respect to the NH group. The process according to the invention is suitable for dyeing natural or synthetic polyamide materials from an aqueous liquor, or for printing with printing pastes; and it is particularly suitable for dyeing from short liquors.
