| 摘要 |
The present invention relates to a process for dyeing or printing manufactur ed natural polymer or synthetic hydrophobic fibre materials, characterized in that it comprises using dyes of the formula (I), where R~1 is hydrogen, hydroxyl or a radical -NHCO-R~6, where R~6 is C~1-C~6alkyl or unsubstituted or C~1-C~4alkyl- or halogen-substituted phenyl, R~2 is hydrogen, hydroxyl or a radical W-R~7, where W is -NHCO- or -S- and R~7 is C~1C~6alkyl or unsubstituted or C~1-C~4alkyl- or halogen-substituted phenyl, R~3 is hydroge n, R~4 is hydrogen or hydroxyl, R~5 is hydrogen, halogen, methoxy, phenoxy or phenylthio, or R~3 and R~4 combine 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 fibre materials and mass dyeing of plastics materials and to producing solid on-tone combinations of plastics material and manufactured natural polymer or synthetic fibre material.
