Abstract: A process for producing a liquid formulation of a basic azo dye from a phenylenediamine I, which may be alkyl or alkoxy substituted, by diazotizing and coupling in acidic solution comprises diazotizing the phenylenediamine with sodium nitrite in the presence of at least two organic acids comprising at least one first acid (A) having a pk A value of A value >=4.1 and performing a nanofiltration after the coupling has ended.

Abstract: Dye formulation comprises 100 parts by weight (pbw) of a solution of a nonsulfonated azo metal complex dye (5-25 wt.%) in an organic solvent (75-95 wt.%), 1-40 pbw polyvinylpyrrolidone and 1-40 pbw of a nonionic surfactant. Independent claims are also included for: (1) production of the dye formulation by mixing the polyvinylpyrrolidone and nonionic surfactant with the dye solution; (2) leather dyed with the dye formulation.

Abstract: A process for preparing liquid formulations of dyes of the general formula I (see formula I) where Y is chlorine or bromine, Z is hydrogen, chlorine, bromine, sulfonic ester, nitro or optionally substituted sulfamoyl, X is -O- or (see formula II) R is alkylene optionally interrupted by oxygen, (see formulas III or IV) m is 1 or 2, n is 0 or 1, p is 0, 1 or 2, An.THETA. is the equivalent of an anion, R1 and R2 are independently hydrogen, optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl or aryl or combine with the joining nitrogen to form a heterocycle, R3 is hydrogen or optionally substituted alkyl, B is hydrogen or C1- to C4-alkyl, B1 is hydrogen, hydroxyl, C1- to C4-alkoxy or C1- to C4-alkyl, where R4 is optionally substituted alkyl and R5 is hydrogen or C1- to C4-alkyl, and the radical may also be an optionally substituted piperazine radical, by diazotizing an amine of the formula II and then coupling the diazonium salt onto a compound of the formula III and also optionally adding solubilizing additives, comprises effecting said diazotizing at a pH set to an acidic value using pure methanesulfonic acid or at least 20 mol% mixtures of methanesulfonic acid in monobasic acids.
