Description

The The invention relates to a security element for security papers, value documents and the like, one open and one illuminated Security Elements contains readable hidden image information. The The invention also relates to a safety arrangement and a method for producing such a security element.

On Product identifiers, value documents or securities applied Holograms, holographic grids and other hologram-like ones Diffraction structures have proven to be non-copyable authenticity features enforced worldwide in recent years. In the meantime, will be but also holograms of counterfeiters imitated and circulated, which the citizen not readily as forgeries can be recognized.

Around an objective authenticity check holograms or hologram-like ones To enable structures are therefore often additional Information in the design of the hologram or in the holographic Foil introduced, which quickly with appropriate read-out devices can be verified.

An example of the introduction of hidden information in the design of a hologram shows the document US 5,396,559 , It discloses a security element with a pattern of hologram points containing hidden information or coding. The pattern of hidden information includes a reference pattern that allows reading the hidden information. When observing the coding pattern by the reference pattern in register-accurate arrangement, the hidden information is decoded and thus visible.

In the design of the publication U.S. 4,684,795 a hologram is combined with a machine-readable, non-optical information. In this case, hidden information on a badge is placed on a magnetic strip on which a holographic image is provided.

It is also known and for example in the document US Pat. No. 6,392,768 B1 described to record in a dot matrix hologram hidden optical information, which can be read by irradiation of the hologram with convergent laser light as a real image on a projection screen.

However, these possibilities for securing authenticity are now often known to counterfeiters. The invention is therefore based on the object to provide a security element of the type mentioned above _; which avoids the disadvantages of the prior art. In particular, the security element should be provided with novel hidden image information and thus have higher counterfeit protection.

These Task is characterized by the security element with the characteristics of Main claim solved. A safety arrangement and a method for producing a Security element according to the invention are given in the independent claims. further developments The invention are the subject of the dependent claims.

• – einen Wiedergabebereich mit ersten Bildelementen, die die offene Bildinformation darstellen, und mit zweiten Bildelementen, die die versteckte Bildinformation erzeugen,
• – einen von dem Wiedergabebereich beabstandeten Beleuchtungsbereich, und
• – einen den Wiedergabebereich und den Beleuchtungsbereich verbindenden Lichtleiter, der auf den Beleuchtungsbereich auftreffende Auslesestrahlung zum Wiedergabebereich leitet,

wobei die zweiten Bildelemente so eingerichtet und ausgelegt sind, dass sie die versteckte Bildinformation nur erzeugen, wenn sie mit vom Lichtleiter zum Wiedergabebereich geleiteter Auslesestrahlung beaufschlagt sind.According to the invention contains a generic security element

• A display area having first picture elements representing the open picture information and second picture elements generating the hidden picture information,
• A lighting area spaced from the display area, and
• A light guide connecting the display area and the lighting area, which passes to the display area incident on the illumination area,

wherein the second picture elements are arranged and designed such that they generate the hidden image information only when they are loaded with readout radiation guided by the light guide to the reproduction area.

The Invention is thus based on the idea of hidden image information to make visible that not as usual the area in which the hidden information is lit up with a read beam but one of them spatially separate area. This is already the presence of a hidden Information for not Insiders difficult to detect. Even if the effect is detected is, is for his reenactment requires a high physical-optical know-how, so that a security element equipped therewith a high security against counterfeiting offers.

The Open image information of the first picture elements is preferred already visible with ambient lighting of the playback area, while the hidden image information preferably only at admission of the illumination area is detectable with laser radiation.

In preferred embodiments of the inventions The open image information represents a hologram, a holographic grating image or another hologram-like diffraction structure. The first image elements of the reproduction area can be produced holographically, by the dot-matrix method or by electron beam lithography.

The second picture elements of the reproduction area are advantageously holographic produced. In particular, the second picture elements are included produced at such an angle between reference and object beam, that they only generate the hidden image information when the readout radiation impinges substantially parallel to the plane of the security element. However, the second picture elements of the playback area can also in the dot-matrix method or produced by electron beam lithography.

In an advantageous variant of the invention are the first and / or second picture elements by embossed Relief structures formed. In other variants of the invention, the first and / or second picture elements also in a volume hologram be formed.

It lends itself to the first and second picture elements within each other of the playback area overlapping train. With overlap is meant that the first and second picture elements at least partly the same surface areas of the playback area so that these areas are both pixels included at the same time. Are the first and second picture elements for example, by embossed Relief structures formed, so can these relief structures occupy the same areas and at appropriate lighting the open or additionally the hidden image information produce.

alternative can the first and second picture elements also separate area areas occupy. For example, you can necessary for generating the open and hidden image information Pixels are broken down into narrow strips and these strips alternate be arranged in the playback area, so that a nested Structure of first and second picture elements is created without a surface area contains both picture elements at the same time. Of course, instead of the stripes other small, similar or dissimilar shaped surface elements chosen be the width of the strip or the extent of the small surface elements preferably in at least one dimension below the resolution limit of the bare one Chosen eye will, so the subdivision for the viewer is not visible.

Of the Lighting area of the security element advantageously contains a holographic Grid for coupling the incident read radiation in the Light guide. The holographic grating can, for example, by embossed Relief structures or formed in a volume hologram be. The lattice constant of the holographic grating is suitably chosen so that it hits at a predetermined angle of incidence read radiation a predetermined wavelength in a direction parallel to the surface of the security element distracts the playback area. Preferably, the predetermined is Incidence angle between 45 ° and 90 ° to the surface of the security element.

Of the Distance between the lighting area and the playback area is preferably between 2 mm and 30 mm, particularly preferred between 5 mm and 15 mm. At these intervals, on the one hand, a good transmission the coupled radiation from the illumination area to the playback area On the other hand, the lighting area on the Safety element visually clearly separated from the display area be so that the interaction of the invention Areas will not become obvious.

It It is understood that the lighting area for this purpose too integrated into the other design of the security element can to its importance for the authenticity check to hide. In an advantageous development, the illumination area therefore additionally third picture elements containing another open picture information, and / or fourth picture elements, which provide further hidden picture information produce. That way the intended purpose of the lighting area is even further obscured. The interaction of the lighting and the playback area is practically not recognizable.

In preferred embodiments provides the more open image information the third picture elements a hologram, a holographic lattice image or another hologram-like one Diffraction structure. For example, several holographic Lattice with different lattice constants arranged side by side and so an appealing play of colors when tilting the security element produce. One of the holographic grids is designed to that it works as a lighting area according to the invention, So with illumination with suitable read radiation the impinging Radiation, as described above, coupled into the hologram film.

The third picture elements and / or the fourth picture elements are advantageous holographic, dot-matrix or electron beam lithography produced.

The fourth picture elements can For example, be set up and designed such that the further hidden image information only by irradiation with light predetermined wavelength on a projection screen can be read out. The one for it provided read-out radiation differs in terms of its wavelength appropriate from the selection radiation, in which the second picture elements hid the Generate image information.

alternative can the fourth picture elements are set up and designed so that they only generate the more hidden image information if they with incident on the playback area and the light guide to the illumination area guided read radiation vorbestimmter wavelength are charged. The playback area works in this case for the fourth Picture elements as a lighting area and the lighting area accordingly as a playback area.

It lends itself to the generation of the other open and / or hidden image information necessary third and fourth picture elements as well as for coupling the readout radiation into the light guide serving holographic grating into small surface elements and to disassemble to arrange them alternately in the lighting area, so that a nested Structure of holographic grating and third and / or fourth Picture elements are created.

In an advantageous development, the security element contains a embossed Foil whose embossing areas form the display area and / or the lighting area. Especially Both the reproduction area and the illumination area are preferred through embossed areas formed of the film. The film itself represents a light guide, the coupled from the illumination area in the film readout radiation leads to the playback area.

It lends itself to, the embossed Foil, for example, to improve the light guide properties with high-indexing dielectrics or metal layers to be. The foil may be used to apply the security element to a substrate as well be provided with an adhesive layer whose refractive index of the Refractive index of the film deviates, the deviation .DELTA.n preferably is about 0.01. According to others Embodiments of the invention may further provide the embossed film be printed with transparent and / or opaque inks. These print layers can the improvement of the optical fiber properties of the film or else the embedding of the illumination area and / or the reproduction area to serve in the design of the security element.

It It is understood that the security element also additional Layers, such as a protective layer or further effect layers, may have with other security features.

The Invention contains also a security arrangement for Security papers, value documents and the like with a security element, which contains an open and a readable hidden image information, and with a separate light guide element. In this case, the security element a display area with first picture elements that the open Represent image information, and with second pixels that the create hidden image information as well as one spaced from the display area Lighting area. The light guide element is during the read process optically coupled to the display area and the illumination area, around the illumination radiation incident on the illumination area to the playback area. The second picture elements of the playback area are set up and designed so that they are hidden Generate image information only if it is guided by the light guide to the playback area Read radiation are applied.

The Invention finally includes also a security paper for the production of value documents or the like, with a Security element of the type described is equipped, as well a disk, in particular a document of value, such as a banknote, identity card or The like, with a security element of the type described.

Further embodiments as well as advantages of the invention are described below with reference to FIGS explains in their representation on a scale and proportion Play has been omitted in order to increase the clarity.

It demonstrate:

1 a schematic representation of a holographic security element according to an embodiment of the invention,

2 the security element of 1 upon exposure of the illumination area with suitable read-out radiation in a designated viewing direction,

3 a cross section through a holographic security element according to the invention,

4 a schematic diagram for explaining the production of security elements according to the invention, and

5 a cross section through a holographic security element according to another embodiment of the invention.

To further illustrate the invention shows 1 a schematic representation of a holographic security element 10 , which is intended as a product identifier or for application to securities or security documents.

The security element 10 contains a playback area 12 and a lighting area 14 , Under normal lighting conditions, such as daylight, the playback area will show 12 an open image information 16 in the form of a holographic motif, such as the one in 1 exemplified cube model.

The playback area 12 also contains hidden information 18 However, in normal lighting conditions and also when the playback area is illuminated 12 is not visible with laser radiation. Only if the lighting area 14 , as in 2 shown at a preselected angle of incidence with readout radiation 20 a suitable preselected wavelength is illuminated, the hidden image information 18 , which is represented in the embodiment by the letter sequence "OK", visible from a particular viewing direction.

The construction and the basic operation of the invention will now be described with reference to 3 which illustrates a cross section through a security element according to the invention 30 shows. There are in the 3 only the elements of the security element essential to the invention 30 shown. It is understood, however, that a real security element typically has a number of other elements, such as a carrier layer, a protective layer, one or more print layers, etc.

The security element 30 contains a hologram foil 36 with two embossed areas 32 and 34 that the playback area 12 or the lighting area 14 of the security element. The two embossing areas are typically arranged at a distance of between 2 and 30 mm from each other on the security element. In the embodiment, a distance d of 10 mm is selected.

The the lighting area 14 forming embossing area 34 contains a holographic grating, the lattice constant of which is chosen so that it reaches at a predetermined angle of incidence readout radiation 40 a predetermined wavelength in the hologram foil 36 couples. For example, the grating may be aligned with a vertical incidence of the radiation of commercial laser pointers with λ = 635 nm. Incident radiation whose wavelength or angle of incidence is outside a certain tolerance range does not enter the film from the holographic grating 36 coupled.

In addition, the lighting area 14 forming embossing area 34 Also contain other holographic gratings with lattice constants, which differ from the lattice constant of the coupling of the read-out radiation 40 differentiating grid. The stamping area 34 For this purpose, it can be broken down into small area elements which alternate or arranged in another way flat with each other nested. The extent of the small surface elements is chosen in at least one dimension below the resolution limit of the naked eye, so that the subdivision is not visible to the viewer. The further holographic gratings can, for example, produce an appealing color play when tilting the security element, as a result of which the interaction of the reproduction area 12 and the lighting area 14 is practically not recognizable.

The hologram foil 36 self-forms in the area 38 between the two embossed areas 32 . 34 a light guide, the coupled radiation 42 from the lighting area 14 to the playback area 12 passes.

The playback area 12 forming embossing area 32 Contains first and second picture elements, overlapping each other, in the hologram foil 36 embossed relief structures are formed. The first picture elements generate the open image information with ambient lighting 16 , such as the holographic representation of the cube model of 1 and 2 ,

The second picture elements can be the hidden picture information 18 In the exemplary embodiment, the letter sequence "OK" is produced, and according to the invention, they are designed such that they display the hidden image information 18 only reconstruct if the readout radiation 42 essentially parallel to the security element level 30 impinges on the second image elements forming relief structure. If this condition is fulfilled, the second picture elements generate from the readout radiation which is running in the light guide 42 the hidden image information 18 otherwise the image information remains 18 hidden.

Depending on the design of the second picture elements, the hidden picture information 18 be visible only at a certain viewing angle or in a wider range of angles. It is understood that the hidden image information can also contain more complex information than the letter sequence shown in the embodiment. The hidden image information may contain, for example, a plurality of sub-image information that is generated when different subareas of the illumination area are illuminated, or that are reconstructed when the illumination area is illuminated in different viewing directions. The partial image information can be, for example, a series of movements of an image motif or an enlarging or reducing contour of an image motif, so that a sequence of movements or a pump image of the image motif is generated during readout.

The inventive design of the second picture elements ensures that the hidden image information 18 only when lighting the lighting area 14 and not by lighting the playback area 12 can be read, since in the latter case, the reconstruction condition can not be met regardless of the lighting conditions. Such a security element offers a high security against counterfeiting, since it is difficult to reproduce for potential imitators because of the physical-optical know-how required for its production.

To produce such a security element, for example, proceed as follows:
With reference to the outline of the 4 First, a hologram with the desired open image information 16 on a photoresist plate 50 exposed. This exposure step can be carried out by known methods, for example by dot-matrix technique, holographic exposure or electron beam technique. The first exposure step is in the photoresist plate 50 a latent image 52 the first picture elements of the playback area 12 generated.

Subsequently, the latent image 52 on the not yet developed photoresist plate 50 a second time, for example, holographically exposed to a latent image of the second picture elements within the display area 12 to create. This is done in the object beam 54 a screen 56 in combination with a film mask 58 with the image information to hide 18 brought in.

The angle φ between the reference beam 60 and the object beam 54 is chosen according to the invention so that the image information to be hidden 18 can be reconstructed during the read-out process only when the read-out radiation impinges substantially parallel to the plane of the hologram.

Thereafter, at a distance of 2 to 30 mm, preferably 5 to 15 mm, to the latent image of the reproduction area 12 a holographic grating is imprinted, whose lattice constant is chosen so that, for example, vertically incident laser light of a defined wavelength of the holographic grating deflected in a direction parallel to the resist surface and in the playback area 12 is decoupled again.

After these exposure steps, the exposed photoresist plate becomes 50 developed with conventional photoresist developer and close to the usual steps for the production of embossing matrices and embossing in embossable films 36 or provided with Prägelackschichten films to Mas sen production of hologram labels, hot stamping foils, hologram laminate films and the like.

5 shows a security element 70 according to a further embodiment of the invention. At the security element 70 is the embossed hologram foil 36 over an adhesive layer 72 on a substrate 74 , such as a plastic card or a paper substrate applied. To improve the light conduction within the hologram foil 36 The refractive index n _{K of} the adhesive layer expediently deviates from the refractive index n _{F of} the film by about 0.01.

To amplify the optical fiber effect and / or to add further information or effects is the hologram film 36 after application with transparent lacquer 76 printed. In addition, in the exemplary embodiment, the area between the illumination area 14 and playback area 12 with a non-transparent printing ink 78 Printed to embed the two areas in the overall design of the security element.
