Abstract

Use of aminotriarylmethanes of the formula ##STR1## where the ring A may be benzofused, and PA1 R.sup.1 and R.sup.2 are each substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl or substituted or unsubstituted phenyl, or R.sup.1 and R.sup.2 are together with the nitrogen atom joining them together a heterocyclic radical, or else R.sup.1 is hydrogen, PA1 R.sup.3 and R.sup.4 are substituted or unsubstituted C.sub.1 -C.sub.20 -alkyl or else R.sup.3 is hydrogen, and PA1 X.sup.1 and X.sup.2 are each substituted or unsubstituted C.sub.1 -C.sub.13 -alkyl or a radical of the formula NR.sup.1 R.sup.2, or else one of X.sup.1 and X.sup.2 is hydrogen, for marking hydrocarbons, hydrocarbons comprising the abovementioned aminotriarylmethanes, a method for detecting the aminotriarylmethanes in hydrocarbons, and novel aminotriarylmethanes.
