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: A process for printing or coating a substrate with a liquid-crystalline composition and at least one non-liquid-crystalline print or coating as a multilayer and a substrate produced by this process is described. The liquid-crystalline composition contains at least one compound having two polymerizable groups and at least one compound having only one polymerizable group, and optional further additives. The non-liquid-crystalline print or coating contains one or more IR- or UV-absorbent or fluorescent dye or pigment. The process and the printed substrate are useful in producing counterfeiting-proof marking of articles.

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.
