Abstract: The present invention relates to a method of marking liquids using at least two markers, wherein said markers absorb in the 600-1200 nm region of the spectrum and reemit fluorescent light and the absorption range of at least one marker overlaps with the absorption range of at least one other marker.The present invention further relates to a method for detecting markers in liquids marked by the method of the invention, which comprises using light sources which emit radiation in the absorption ranges of said markers and detecting the fluorescent light reemitted by said markers, at least one of said light sources emitting radiation in the overlapping absorption range of at least one marker with that of at least one other marker and the number of light sources being less than or equal to the number of markers.The present invention further relates to liquids marked by the method of the invention.

Abstract: Phthalocyanines of the formulawhereMe 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, andany 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.

Abstract: The invention relates to chiral compounds containing at least one divalent or polyvalent chiral group, at least one polymerizable group, at least one spacer and at least one mesogenic group, and to their use as polymerizable, chiral dopes for the preparation of cholesteric networks. The novel compounds are suitable for use in electro-optical displays or as chiral dopes for nematic or cholesteric liquid crystals in order to produce layers which reflect in colors.
