On the other hand, it is also possible to vary the method for preparing the new azo dyes by carrying out the formation of the carbonate groups only in the final stage of the process, that is to say therefore after the coupling of the diazooom.posé and in this case of the aniline coupling component containing oxyethyl groups, or by converting an acylamino group Z in the final stage of the process, by selective saponification and further acylation, into an acylamino group of another kind.
