Method for the preparation of fibre-reactive formazana dyes as well as aminophenols |
| abstract |
Process for the preparation of fiber-reactive formazan dyes by diazotization of a hydroxyphenylenediamine protected by a formyl group and coupling with a hydrazone compound, metallization, removal of the protective group, reaction with a halotriazine and optionally subsequently with an amine or a hydroxy compound and aminophenols as intermediates for the new process. |
