Process for the preparation of new crystal modification of an azo dyestuff |
| abstract |
In the process for the preparation of the dyestuff of the formula I <IMAGE> (I) by diazotization and coupling, the aqueous suspension present when the coupling has ended is heated to temperatures of 50 DEG C. up to the boiling point of the aqueous phase in the presence of a dispersing agent. |
