Abstract:
The present invention relates to the use of specific phthalocyanines which bear substituents on the basic phthalocyanine structure bonded via methylene groups as markers for liquids, especially mineral oils, to liquids, especially mineral oils which comprise at least one such phthalocyanine as a marker, and also to novel specific phthalocyanines which bear substituents on the basic phthalocyanine structure bonded via methylene groups.
