ABSTRACT:
Monoazo and disazo dyes having an unsubstituted or substituted aniline or p-aminoazobenzene as diazo component and an N-substituted .beta.-naphthylamine of six to eighteen carbon atoms in the N-substituent as coupling component. Preferred diazo components are phenyl, tolyl, phenylazophenyl and tolylazotolyl, and preferred coupling components are provided by .beta.-naphthylamine which is N-monosubstituted by n-hexyl, n-octyl, .beta.-ethylhexyl, 3,5,5-trimethylhexyl, tridecyl, .beta.-ethylhexoxypropyl, cyclohexyl, benzyl or phenylethyl. The dyes are eminently suitable for the coloring of for example mineral oils, gasoline, fats and waxes because of their excellent solubilities.
