ABSTRACT:
The present invention relates to a process for dyeing or printing manufactured natural polymer or synthetic hydrophobic fiber materials, characterized in that it comprises using dyes of the formula (I), where R1is hydrogen, hydroxyl or a radical —NHCO—R6, where R6is C1-C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R2is hydrogen, hydroxyl or a radical W—R7, where W is —NHCO— or —S— and R7is C1C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R3is hydrogen, R4is hydrogen or hydroxyl, R5is hydrogen, halogen, methoxy, phenoxy or phenylthio, or R3and R4combine to form the radical of the formula (II), where the rings A and B may independently bear further substituents, to the use of these dyes for trichromatic dyeing of manufactured natural polymer or synthetic hydrophobic fiber materials and mass dyeing of plastics materials and to producing solid on-tone combinations of plastics material and manufactured natural polymer or synthetic fiber material.
