Use of compounds of general formula (I) or (II) as markers for liquids, where R1- R6 and R11- R18 independently, identically or differently represent H, C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C3-C15 cycloalkyl, aryl, aryloxy, heterocycles, halogen, NR7R8, CN, NO2, CONR7R8, OR9, COR9, COOR9, SO3R9; R7 - R9 independently, identically or differently represent H, C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C3-C15 cycloalkyl, aryl, and where one or more C atoms in any position in the aromatic ring, along with the respective substituent R1- R6 and R11- R18, can be identically or differently substituted by N, O, or S atoms, wherein preferably no more than 3, especially preferably no more than 2, and in particular no more than 1 C atom(s) in formulae (I) or (II) is/are substituted, and wherein substituents R1- R6, R7 - R9, R11 - R18 can be interrupted in any position by one or more, but no more than 10, preferably no more than 8, especially preferably no more than 5, and in particular no more than 3 heteroatoms, and/or can be substituted in any position, but no more than five times, preferably no more than four times, and especially preferably no more than three times, by NR7R8, CONR7R8, COR9, COOR9, SO3R9, CN, NO2, C1-C20 alkyl, C1-C20 alkoxy, aryl, aryloxy, heterocycles, heteroatoms, or halogen, wherein the same can also be substituted up to twice, preferably no more than once, by said groups, provided that at least two of substituents R1- R6 in formula (I) represent COOR9, wherein the presence of the marker is detected using a method allowing markers of general formula (I) to be distinguished from other compounds of general formula (I) if exactly two of substituents R1- R6 represent COOR9, and provided that at least two of substituents R11 - R18 represent COOR9 in formula (II). |
