Definitions
- the invention relates to a document of value, such as security, identification card or the like, with at least one authenticity feature in the form of a luminescent substance.
- the invention further relates to a security element with at least one authenticity feature in the form of a luminescent Substance and a method for marking products, wherein the product is provided with a luminescent substance.
- Marking products are particularly useful for security applications long used luminescent substances.
- the advantage of one Such marking is that with suitable lighting of the marked object the luminescent substances with high intensity emit and thus detectable, while areas without the luminescent Substances appear essentially dark. To this The markings can be detected with high sensitivity.
- numerous luminescent substances were used for marking used that have very broad emission bands. This is particularly typical for organic dyes whose luminescence line widths are some Can be 50 nm and more. They also have similar line widths many classic inorganic luminescent substances.
- EP 0 522 627 A1 describes the production of luminescent molecular sieves and their use as lamp fluorescent.
- reactants complexing agents and rare earth ions
- the Cavities of zeolites are introduced, where they react to chelate complexes.
- the chelate complex is fixed inside the cavities.
- colored molecular sieves are the metal salts as color Component included, for a long time under the name "Ultramarine dyes / -pigments known (German Reichspatent No. 1, 1877).
- This pure Inorganic systems are made, for example, by heating zeolite molecular sieves with alkali metal sulfides in a non-oxidizing atmosphere and then in an oxidizing atmosphere at temperatures above 300 ° C (JP-A-63-017 217; JP-A55-071 762).
- Organic dyes are usually made by treating colorless ones Molecular sieves with dye solutions applied to the molecular sieves (see e.g. JP-A-63-0 17 217; JP-A-53-0 22 094 and JP-A-75-0 08 462).
- dye solutions applied to the molecular sieves see e.g. JP-A-63-0 17 217; JP-A-53-0 22 094 and JP-A-75-0 08 462).
- Adhesion is achieved with strongly basic dyes.
- pigments consisting of an inorganic carrier (often layered minerals, zeolites or zeolite-like materials) and an adsorbed colorant, in paints and emulsion paints is known (JP-PS-75-0 08 452).
- JP-PS-75-0 08 452 When using these pigments it is necessary to change the composition choose the color so that the color pigment does not match the surrounding medium reacts in the solvent used is insoluble and uniformly sedimented, which is particularly the case with mixed colors is important. This makes many of them interesting for color production Solvents and binders excluded and the possibilities of mixed color production severely restricted using the pigments described.
- the systems and uses described have in common that the luminescent substances retain their characteristic properties that they also in solutions or as a powder. By installation in the zeolite only slight shifts, especially with organic dyes and broadening of the spectral bands were observed. For the However, these effects are not advantageous when used as a marker. There they overlap the emission bands of numerous different luminescent substances, the selectivity of the detection of the substances is severely restricted. Although there are chemically different substances, the differences are their emission bands often so low that their luminescence over a wide spectral range can be investigated with complex means must be so that identification is possible at all. For many applications is the effort of a clear identification so high, that it can only be carried out in exceptional cases.
- the invention is therefore based on the object of a document of value as well a security element for marking any product with at least propose a luminescent substance that is easy to detect and is identifiable.

- the coding arises from the presence or absence of one or more Particle.
- the characteristic properties of the dye-molecular sieve systems only become apparent when there is intensive optical excitation with light of a suitable wavelength. Due to the threshold behavior of the systems, the optical irradiance must exceed a threshold value that is characteristic of the systems. Typical threshold values are 0.2-4 MW / cm 2 .
- Light sources of suitable wavelength with sufficient radiation power can be used as the excitation source.
- An optical device can be used to concentrate the light from the excitation source on a sufficiently small spot and thus to increase the irradiance of the systems.

- the characteristic increase in intensity in a narrow wavelength range with excitation above threshold the characteristic Threshold behavior of the increase in intensity when the Irradiance using a suitable spectrally constricting element be detected in the detection channel.
- the characteristic narrowing of the luminescence line can be determined by the Comparison of the intensities in the characteristic of the dye system narrow wavelength range with the intensity in other wavelength ranges be detected. This happens e.g. using a spectrometer setup sufficient spectral resolution or by measuring in different Detection channels by suitable spectrally selective elements measure the intensity in the required spectral range. In case of transient A characteristic spectral distribution is observed with excitation with an intensity maximum at the characteristic wavelength or characteristic intensity relationships in the different channels, that do not occur with conventional luminescent dyes.
- Another characteristic feature of the systems is the saturation of the optical transition only at much higher luminescence intensities, so that with these systems much higher luminescence intensities can be observed than with conventional luminescent substances.

Description
DE 41 26 461 beschreibt die Herstellung solcher Materialien sowie deren Einsatz als Pigment und optischen Datenspeicher. Farbstoffe, wie z.B. Phthalocyanine, Phenoxazine, Azofarbstoffe usw. werden irreversibel fixiert, indem das Molekularsieb um den Farbstoff herum in-Situ gebildet wird. Diese Technik wird allgemein als "Crystallisation-Inclusion" bezeichnet (G. Schulz-Ekloff "Nonlinear optical effects of dye-loaded molecular sieves" in Advanced Zeolite Science and Application Studies in Surface Sciences Catalysis, Vol. 85 (1994), 145 -175). Eine weitere Methode zur irreversiblen Fixierung von Farbstoffen in Molekularsieben, die "ship-in-the-bottle-Synthese", wurde z.B. von G. Meyer et al. beschrieben (Zeolites 4 (1984), 30). Hierzu werden Übergangsmetall-ausgetauschte Zeolithe mit o-Phthalodinitril umgesetzt, wobei der Farbstoff (Cobalt-, Nickel- oder KupferPhthalocyanin) in den ca. 12 Å großen Superkäfigen des Faujasits gebildet wird. Da diese Superkäfige nur durch ca. 7 Å bis 8 Å große Öffnungen zugänglich sind, kann zwar das Phthalodinitril in die Hohlräume hineindiffundieren, ein Herausdiffundieren des gebildeten Farbstoffes ist jedoch aus sterischen Gründen nicht mehr möglich.
