DYEING OR PRINTING OF MANUFACTURED NATURAL POLYMER AND SYNTHETIC HYDROPHOBIC FIBRE MATERIALS

摘要

The present invention relates to a process for dyeing or printing manufacturednatural polymer or synthetic hydrophobic fibre materials, characterized inthat 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 orC~1-C~4alkyl- or halogen-substituted phenyl, R~2 is hydrogen, hydroxyl or aradical W-R~7, where W is -NHCO- or -S- and R~7 is C~1C~6alkyl orunsubstituted or C~1-C~4alkyl- or halogen-substituted phenyl, R~3 is hydrogen,R~4 is hydrogen or hydroxyl, R~5 is hydrogen, halogen, methoxy, phenoxy orphenylthio, 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 theuse of these dyes for trichromatic dyeing of manufactured natural polymer orsynthetic hydrophobic fibre materials and mass dyeing of plastics materialsand to producing solid on-tone combinations of plastics material andmanufactured natural polymer or synthetic fibre material.
