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: The use of azo dyes of the formula (I) in which ring A can be benzoanellised, n is 0 or 1, R1 is hydrogen or possibly substituted C1-C5 Alkyl, R2 is possibly substituted C1-C15 alkyl, R3, R4, R5, R6 and R7 are hydrogen, C1-C15 alkyl or C1-C15 alkoxy, and R8 is hydrogen, C1-C15 alkyl, C1-C15 alkoxy, cyano, nitro or a carboxyl radical which may be esterified, as pH-dependent markers for hydrocarbons, hydrocarbons containing said azo dyes, a process for detecting said azo dyes in hydrocarbons and novel azo dyes.
