Process for trichromatic dyeing or printing

A process for the trichromatic dyeing or printing of natural or synthetic polyamide fibre materials, which comprises using at least one blue-dyeing anthraquinone dye of the formula ##STR16## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4, independently of one another, are hydrogen or C.sub.1 -C.sub.6 alkyl, the sum of the carbon atoms of the radicals R.sub.1, R.sub.2, R.sub.3 and R4 being 4, 5 or 6 and the sulfo group in the anthraquinone dye of the formula (1) being attached in the position designated as 6 or 7, together with at least one red-dyeing dye of the formula ##STR17## in which R.sub.5 is phenyl or cyclohexyl and R.sub.6 is C.sub.1 -C.sub.4 alkyl, or the radicals R.sub.5 and R.sub.6 together with the nitrogen atom linking them form an azepinyl ring, and at least one of the yellow- or orange-dyeing dyes of the formulae (3), (4) and (5) ##STR18## in which R.sub.7 and R.sub.8 independently of one another, are hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, R.sub.10 is sulfo, C.sub.2 -C.sub.4 alkanoylamino, halogen or sulfo, R.sub.9 is hydrogen or C.sub.1 -C.sub.4 alkyl, and n is 1, 2, 3 or 4, ##STR19## in which B.sub.1, B.sub.2 and E.sub.1 are hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy and X is straight-chain or branched C.sub.1 -C.sub.4 alkyl or straight-chain or branched C.sub.2 -C.sub.4 hydroxyalkyl, ##STR20## in which W.sub.1 is phenylsulfonyl which is unsubstituted or substituted in the phenyl ring by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halogen, W.sub.2 is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, W.sub.3 is C.sub.1 -C.sub.4 alkyl or unsubstituted or C.sub.1 -C.sub.4 alkyl-, C.sub.1 -C.sub.4 alkoxy- or halogen-substituted phenyl, and W.sub.4 is hydrogen or C.sub.1 -C.sub.8 alkyl.
