摘要： The invention relates to a method for producing a liquid formulation of salts of sulfoacidic azo dyes, comprising the following steps: a) production of vesuvine from m-phenylenediamine; b) without the intermediate isolation of the vesuvine, coupling of at least an equimolar quantity of diazotized aminoaryl sulfonic acids (I) H2N - Ar - SO3H, to vesuvine, whereby in said formula Ar represents phenylene, which is monosubstituted with a sulfo group, or represents naphthylene, which can be mono- or disubstituted with a sulfo group and/or monosubstituted with a hydroxy group; and c) isolation of the dyes in their acidic form and subsequent dissolution in aqueous bases.

摘要： The invention relates to a method for producing liquid adjustments of basic azo dyes from a phenylenediamine I, which can be substituted by alkyl or alkoxy, by diazotization and coupling in an acidic solution. According to said method, the phenylenediamine is diazotized with sodium nitrite in the presence of at least two organic acids comprising at least one first acid (A) with a pkA value of = 4.0 and at least one second acid (B) with a pKA value = 4.1 and a nanofiltration is carried out once the coupling has been completed.
