Patent

CA 2288703

The invention relates to phthalocyanine of formula (I), wherein Me means twice hydrogen, twice lithium, magnesium, zinc, copper, nickel, VO, TiO, AlCl, A1OH, AlOCOCH3, AlOCOCF3, SiCl2or Si(OH)2, at least four of the radicals R1 to R16 independently mean a five or six-membered saturated nitrogenous heterocyclic radical which is bonded to the phthalocyanine sceleton by a cyclic nitrogen atom and may contain other heteroatoms, and optionally, the remaining radicals R1 to R16 mean hydrogen, halogen, hydroxy sulfonyl or C1-C4 dialkyl sulfamoyl, with the exception of tetrakispiperidinyl phthalocyanine. The invention also relates to the use of phthalocyanines by heterocyclic radicals for marking liquids such as mineral oils which contain phthalocyanines of this type.

L'invention concerne de la phtalocyanine de la formule (I) dans laquelle Me désigne deux fois hydrogène, deux fois lithium, magnésium, zinc, cuivre, nickel, VO, TiO, AlCl, AlOH, AlOCOH3, AlOCOCF3, SiCl2 ou Si(OH)2, au moins quatre des restes R<1> à R<16> désignent indépendamment les uns des autres un reste hétérocyclique saturé contenant de l'azote, ayant 5 ou 6 chaînons, ledit reste étant lié par un atome d'azote cyclique au squelette de la phtalocyanine et pouvant contenir également d'autres hétéroatomes, et éventuellement les restes résiduels R<1> à R<16> désignent hydrogène, halogène, hydroxysulfonyle ou dialkylsulfamoyle C1-C4, la tétrakispipéridinylphtalocyanine étant exceptée. L'invention concerne l'utilisation de phtalocyanines substituées par des restes hétérocycliques pour marquer des liquides, ainsi que des huiles minérales contenant une phtalocyanine de ce type.
