Process for trichromatic dyeing or printing

A process for the trichromatic dyeing or printing of natural and synthetic polyamide fibre material by means of mixtures of reactive dyes, which comprises treating these fibre materials with a dye liquor or printing paste which contains a blue-dyeing reactive dye of the formula ##STR79## in which X is halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, cyano or nitro, n is the number 0, 1 or 2, q is the number 0 or 1, m is the number 1, 2 or 3, Z is halogen and Y is a CN, CHO or S(O).sub.p R group in which p is the number 0, 1 or 2 and R is phenyl or C.sub.1 -C.sub.8 alkyl which is unsubstituted or substituted by halogen or phenyl, together with at least one yellow- or orange-dyeing sulfo-containing reactive dye of the formulae ##STR80## and at least one red-dyeing sulfo-containing reactive dye of the formulae ##STR81## in which acyl is acetyl or benzoyl, R' is difluorochloropyrimidinyl, .alpha.,.beta.-dihalogenopropionyl or .alpha.-halogenoacryloyl, and the fused rings indicated by dots represent naphthalene systems which are a possible alternative.
