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 Ris hydrogen, hydroxyl or a radical —NHCO—R, where Ris C-Calkyl or unsubstituted or C-Calkyl- or halogen-substituted phenyl, Ris hydrogen, hydroxyl or a radical W—R, where W is —NHCO— or —S— and Ris CCalkyl or unsubstituted or C-Calkyl- or halogen-substituted phenyl, Ris hydrogen, Ris hydrogen or hydroxyl, Ris hydrogen, halogen, methoxy, phenoxy or phenylthio, or Rand Rcombine 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.
