Abstract:
A method for the trichromatic dyeing or printing of natural or synthetic polyamide fibre material, which method comprises contacting the fibre material with a tinctorially effective amount of a dye mixture comprisingat least one blue-dyeing dye of formula whereinX is halogen, hydroxy, C1-C4alkoxy, Sâ€”C1-C4alkyl, â€”NHR1, â€”NR1R2, morpholino, piperidino or azepano, R1 being unsubstituted C1-C4alkyl or hydroxy- or carboxy-substituted C1-C4alkyl, and R2 being unsubstituted C1-C4alkyl or phenyl or hydroxy-, sulfo-, carboxy- or phenyl-substituted C1-C4alkyl or phenyl, W is â€”NR3â€” or â€”Oâ€”, R3 being hydrogen or C1-C4alkyl, A and B are each independently of the other a cycloaliphatic or aromatic bridge member, Q1 and Q2 are each independently of the other an anthraquinone radical, and z is an integer 2, 3 or 4, together with at least one red-dyeing dye of formula whereinR and Râ€² are each independently of the other hydrogen or unsubstituted or substituted C1-C4alkyl, R5, R6, R7 and R8 are each independently of the others hydrogen, C1-C4alkyl, C1-C4alkoxy, C2-C4alkanoylamino, ureido, halogen or sulfo, and X1 is halogen, hydroxy, C1-C4alkoxy, Sâ€”C1-C4alkyl, â€”NHR1, â€”NR1R2, morpholino, piperidino or azepano, R1 being unsubstituted or hydroxy- or carboxy-substituted C1-C4alkyl, and R2 being unsubstitutied or hydroxy-, sulfo-, carboxy- or phenyl-substituted C1-C4alkyl or phenyl, and together with at least one yellow- or orange-dyeing dye of formula or of formula whereinR and Râ€² are each independently of the other hydrogen or unsubstituted or substituted C1-C4alkyl, X2 and X3 are each independently of the other halogen, hydroxy, C1-C4alkoxy, Sâ€”C1-C4alkyl, â€”NHR1, â€”NR1R2, morpholino, piperidino or azepano, R1 being unsubstituted or hydroxy- or carboxy-substituted C1-C4alkyl, and R2 being unsubstituted or hydroxy-, sulfo-, carboxy- or phenyl-substituted C1-C4alkyl or phenyl, and R9, R10, R11, R12, R13, R14, R15 and R16 are each independently of the others hydrogen, C1-C4alkyl, C1-C4alkoxy, ureido, halogen, sulfo, or C2-C4alkanoylamino or C1-C4alkoxycarbonylamino each of which is unsubstituted or substituted in the alkyl moiety.
