Abstract
The present invention relates to a method for the trichromatic dyeing or printing of natural or synthetic polyamide fiber material, which method comprises using at least one blue-dyeing dye of formula wherein X, W, A, B, Q1, Q2 and z are as defined in claim 1 for formula (1), together with at least one red-dyeing dye of formula wherein R, R′, R5, R6, R7, R8 and X1 are as defined in claim 1 for formula (2), and together with at least one yellow- or orange-dyeing dye of formula or of formula wherein R, R′, X2, X3, R9, R10, R11, R12, R13, R14, R15 and R16 are as defined in claim 1 for formulae (3) and (4), and to new acid dyes.
Claims6
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 comprising
- at least one blue-dyeing dye of formula
- wherein
- X is halogen, hydroxy, C1-C4alkoxy, S—C1-C4alkyl, —NHR1, —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 —NR3— or —O—, 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
- wherein
- R and R′ 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, S—C1-C4alkyl, —NHR1, —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
- wherein
- R and R′ 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, S—C1-C4alkyl, —NHR1, —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.
