    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： Disclosed are dye formulations containing A) 5 to 25 percent by weight of at least one unsulfonated azo metal complex dye, B) 75 to 95 percent by weight of an organic solvent, C) 1 to 40 percent by weight of polyvinylpyrrolidon, and D) 1 to 40 percent by weight of a non-ionic surfactant, the percentages by weight being in relation to 100 percent by weight of the mixture of components A and B. Also disclosed are the production of the inventive dye formulations, the use thereof for dying leather, and correspondingly dyed leather.
