METAL SALTS AS MARKING AGENTS FOR COMBUSTIBLE BITUMEN
The present invention relates to the use of metal salts of formula (I) in which M is the equivalent of a cobalt or iron ion, Q is C4-C22-alkyl, C4-C22-alkenyl, aryl or hetaryl, L is carbonyl or sulphonyl, X is a monovalent inorganic anion, m is 1, 2 or 3, y is 0, 1 or 2, and n is the sum of m and y...
