  • the ID card can also be examined under lighting conditions in which it is illuminated exclusively with UV excitation radiation, ie with the exception of the luminescence, the illumination space is completely or at least largely dark.
  • a UV light source UV for example, emits electromagnetic radiation at 365 nm.

Absorptive pattern elements 210 in the form of an absorptive pattern element layer 240 are subsequently formed on the luminescence pattern elements. The absorptive pattern elements are also largely formed register-accurate on the luminescence pattern elements. With regard to the structure of the pattern elements 280 of absorptive and luminescent pattern elements and the selection of the luminescent means and absorptive spectral filter means, reference is made to the example of FIG Fig. 3a Referenced.

  • a single pattern element layer 260 of pattern elements 280 is obtained, for example, even if absorptive pattern element layers 240 and luminescence pattern element layers 250 (as shown in FIG Fig. 3a or 3b ) are formed and this product layer then combined with a further product layer 110 'and further processed under the action of elevated temperature and elevated pressure to form a laminate.
  • the luminescent means and absorptive spectral filter means diffuse into the adjacent product layers 110, 110 'and into each other, respectively, so that a single pattern element layer 260 of combined luminescent and absorptive pattern elements is formed ( Fig. 3d ).
  • Fig. 4 are the conditions when irradiated with white light (VIS) ( Fig. 4a ) and with UV radiation (UV), for example with narrow-band radiation at 312 nm, ( Fig. 4b ).
  • the visible light is symbolized by the basic colors blue (b), green (g) and red (r).
  • the at least one luminescent agent which forms this luminescence pattern element is completely or at least substantially radiation-transparent in the visible spectral range and also preferably non-scattering, therefore transparent (or optionally translucent) and colorless (or only slightly colored). That is in Fig.
  • Absorptive pattern element 210 located below the luminescent pattern element has a red and a green absorption and therefore appears blue to the human eye. For this reason, the red portion (r) and the green portion (g) of the incident light are absorbed in the absorptive pattern element 210 while the blue portion (b) passes through the absorptive pattern element and is remitted. By remission of this proportion of light, the pattern element 280 therefore appears blue.
  • Fig. 4b the conditions are reflected in a lighting exclusively with UV light (UV).
  • the UV radiation entering the pattern element 280 produces in the overhead luminescence pattern element 220 approximately white luminescent light with the color components blue (b), green (g) and red (r).
  • This radiation is emitted non-directionally and enters the underlying absorptive pattern element 210 where it is filtered: the red portion (r) and green portion (g) are absorbed in the absorptive pattern member while the blue portion (b) passes and is remitted , As a result, this pattern element appears blue due to the UV excitation.
  • an underlying luminescence pattern element 220 and an overhead absorptive pattern element 210 which respectively form a luminescence pattern element layer 250 and an absorptive pattern element layer 240 ( Fig. 5 ).
  • VIS visible light illumination
  • Fig. 5a the red component (r) and the green component (g) are already absorbed in the above absorptive pattern element, so that the pattern element 280 appears blue overall.
  • UV radiation UV radiation
  • broadband visible luminescence radiation with a blue component (b), a green component (g) and a red component (r) is generated. Only the blue component of this radiation can pass through the overhead absorptive pattern element, since the green component and the red component are filtered out by the absorptive pattern element.
  • Fig. 6 Further, the relationships with two different pattern elements 280, 280 'differing in the spectral absorption of the absorptive pattern element 210, 210' are shown.
  • the luminescent pattern elements together form a luminescent pattern element layer 250
  • the absorptive pattern elements together form an absorptive pattern element layer 240.
  • the two luminescent pattern elements are formed with the same luminescent agent.
  • different absorptive spectral filter means are in each of the two absorptive pattern elements.
  • the uppermost left pattern element 280 has an absorptive pattern element 210 that absorbs the red portion (r) and the green portion (g) of visible radiation (VIS) that appears blue (b), and each right pattern element 280 'has the blue portion (b ) and the green part (g) absorbing absorptive pattern element 210 'so that this pattern element 280' appears red (r).
  • This structure corresponds to that in Fig. 5 shown.
  • Fig. 6a the situation is shown in the illumination and viewing of the pattern with visible light (VIS) and in Fig. 6b with UV excitation radiation (UV).
  • VIS visible light
  • UV UV excitation radiation
  • the blue portion (b) is remitted in the left pattern element 280, while in the right pattern element 280 ', the red portion (r) is. Therefore, the left pattern element is blue under visible light illumination and the right pattern element is red.
  • a corresponding image is produced under UV irradiation: the red component (r) and the green component (g) of the luminescent light are absorbed in the overhead left absorptive pattern element 210 so that only the blue component (b) of the luminescent light is emitted by the left pattern element 280, while in the overhead right absorptive pattern element 210 ', the blue portion (b) and the green portion (g) of the luminescent light are absorbed and only the red portion (r) of the luminescent light is emitted from the right pattern element 280'. Therefore, the pattern 201 generated by luminescence looks substantially the same as that obtained under visible light irradiation.
  • a luminescent layer with a luminescent agent and an absorptive layer with an absorptive spectral filter means are formed by printing these directly on top of each other on the same surface of a polymer film.
  • the luminescent agent luminesces when excited with UV radiation approximately white.

  • the first name of the document holder and a date in the luminescent color and its face image are printed with a conventional ink containing an absorptive spectrum filter means. Together, this results in a superposition of the first name of the document holder and the date with its facial image, whereby the first name and the date only become visible when the image is irradiated with the UV radiation.
  • the first name and the date not the facial image superimposed, they appear with the original luminescent color of the luminescent agent, namely approximately white.

  • a bar pattern in the luminescent color and the face image of the document holder are printed with a conventional ink containing an absorptive spectrum filter means. Together, this results in a superposition of the bar pattern with the face image of the document holder, whereby the bar pattern is only visible when the image is irradiated with the UV radiation. In the areas of the bar pattern which are not superimposed on the face image, this appears with the original luminescent color of the luminescent agent, namely approximately white. In the areas superimposed on the face image, the bar pattern appears under luminescent lighting conditions with the color of the face image.
  • the luminescent layer in the examples of Fig. 8 can be either rasterized or non-rasterized. This pressure can also be achieved with a planographic printing process, be generated as the offset printing method. Likewise, in these examples, the absorptive layer may be either screened or not screened. Preferably, at least the absorptive pattern is generated with a digital printing process, such as an inkjet process, to take advantage of its flexibility for personalizing patterns.
