Abstract
The invention provides a process for the preparation of a concentrated solution of an azo dyestuff from a diazotisable amine and a coupling component by diazotisation and coupling in the presence of water and of at least one water miscible solvent in which the diazotisation is effected by sodium nitrite in the presence of sulphuric acid, and the sodium sulphate formed is eliminated by filtration.
