摘要:
Phthalocyanines of the formula where Me is twice hydrogen, twice lithium, magnesium, zinc, copper, nickel, VO, TiO, AlCl, AlOH, AlOCOCH3, AlOCOCF3, SiCl2 or Si(OH)2, at least four of the radicals R1 to R16 are each independently of the others a five- or six-membered saturated nitrogen-containing heterocyclic radical which is bonded to the phthalocyanine structure via a ring nitrogen atom and which can additionally contain further hetero atoms, and any remaining radicals R1 to R16 are each hydrogen, halogen, hydroxysulfonyl or C1-C4-dialkylsulfamoyl, subject to the proviso that tetrakispiperidinylphthalocyanine shall be excluded, and heterocyclyl-substituted phthalocyanines are useful for marking liquids, in particular mineral oils.
