Abstract
A process for dyeing surface coatings, organic solvents and petroleum products, wherein the dye used is a compound of the general formula I ##STR1## where R is C.sub.1 -C.sub.17 -alkyl, which may or may not be interrupted by oxygen and may or may not be substituted by hydroxyl or phenoxy, or is allyl, R.sup.1 is hydrogen or C.sub.1 -C.sub.8 -alkyl, R.sup.2 is C.sub.1 -C.sub.12 -alkyl which may or may not be interrupted by oxygen and may or may not be substituted by hydroxyl or phenoxy, or is C.sub.7 -C.sub.11 -aralkyl, X is hydrogen, chlorine, bromine, methyl or methoxy, Y is hydrogen, methyl or chlorine and R.sup.1 and R.sup.2 may also together be the radical ##STR2##
