Abstract: Azo dyes of the formula in which R and R are each hydrogen, C1-C4-alkyl or C1-C4-alkoxy, R is hydrogen or C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, R is C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, and X is cyano or optionally substituted C1-C8-alkoxycarbonyl, with the proviso that at least one hydroxyalkyl radical is present in the molecule, mineral oils containing one or more of the novel dyes, and the use of the novel dyes for labelling mineral oils.

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.
