Definitions

  • the invention relates to a security document with a lateral and a perpendicular extension, with a surface extending along the lateral extension, and with an image layer assigned to the surface and arranged below an optically transmissive layer, the surface taking up a certain depth dimension has unit extending into the optically permeable layer along the vertical extent.
  • the invention also relates to a method for producing a security document with a lateral and a perpendicular extension, and a surface extending along the lateral extension.
  • a security document is understood to be any document or value document that has a security feature.
  • This can be a security and / or value document made of any material, e.g. B. paper or plastic.
  • this can be a card for any purpose, in particular for electronic payments or an ID card, driver's license or another card.
  • the cards are usually made of plastic and multilayered using foils.
  • a security document and / or a data carrier is usually accommodated in a security document as a unit which takes up a certain depth dimension and extends along the vertical extent into an optically permeable layer.
  • a unit of any other type can also be accommodated, e.g. B. a chip module.
  • the thickness of such a unit inevitably affects the design of the security document. If the thickness of the security document is specified in accordance with ISO, the thickness of the units must be taken into account in the design and limits the freedom in the design.
  • the milling depth of a cavity to be provided for a chip module in the security document thus determines the depth dimension of the chip module that is used. If the unit is implemented in the form of an optical structure, the depth dimension is essentially determined by the focal length of the optical structure. In the case of a volume hologram, the thickness of the volume hologram determines the depth dimension used.
  • a security feature can be implemented in a particularly simple manner by means of a so-called "tilt image". Such a tilt image generally has a lateral extent and is realized in the form of a lens structure as an optically effective imaging structure and with an information structure stored in an image layer of the lens structure. Depending on the version of the flip image, a latent image or the latent image disappears in different viewing directions. Such tilting pictures are attached, for example, as security features on check cards. The advantage of this security feature lies in the fact that the tilting pictures can be checked visually relatively easily, which is given even in simple lighting conditions.
  • tilting picture is disclosed for example in EP 0219 012 A2.
  • Tilted pictures of this type are consequently often used as security features, even though the image layer should be arranged at least at a distance of the focal length from the optical imaging structure and they therefore have a certain minimum thickness, which is usually greater than that of holograms.
  • an image layer In conventional card assemblies, such as that shown in FIG. 1, an image layer must therefore maintain a minimum distance from the imaging structure that is predetermined by the focal length of the optical imaging structure of the tilted image. Therefore, the image layer must be placed at a predetermined minimum depth to the surface assigned to it. This adversely limits the design of the structure of the security document. For example, such a security document of FIG. 1 must have a corresponding minimum thickness if one does not want to use a thinner but more complex hologram instead of the particularly easy to implement tilt image.
  • a tilted image is also understood to mean a grating or diffraction structure, as described, for example, in the publication WO 02/11063 A2, in which an angle-dependent effect occurs when reading out, the reading out and reading in of the information into the image layer optionally being laser-assisted, optionally in the invisible area of light.
  • Such an invisible and inconspicuously hidden security feature is known for example from DE 32 33 197 A1.
  • FIG. 2 Another disadvantage arises in the case of a security document according to FIG. 2, which is constructed according to the current state of the art to be arranged on a surface of the security document and to attach a chip module to the surface of the security document opposite this surface without the depression required for the chip module breaking through the image layer provided for the tilted image.
  • This has the disadvantage that the chip module is visible from the surface of the tilt image when the further layers of the
  • Security document optically transparent, d. H. transparent or translucent.
  • Document DE 10032 128 A1 describes a security paper for the production of documents of value in which a chip module is secured in such a way that a layer with a visually testable optical effect is arranged above the chip module and covers the chip module.
  • WO 96/15912 in Fig. 20 z.
  • the embodiment of a security document is shown in which only optical imaging structures are used for a security feature that have a particularly small focal length, and these can thus be arranged on opposite surfaces of a security document.
  • such a security document of FIG. 20 of WO 96/15912 must have a thickness that is somewhat more than twice as large as the focal length of the optical imaging structures arranged on opposite surfaces of the security document.
  • the publication describes a relatively complex manufacturing process for the security document, in which the security feature implemented as an optical imaging structure is produced as a separate unit and must be subsequently implemented in the security document. The latter is shown in Figures 15 to 20 of WO 96/15912.
  • Another object of the present invention is to provide a simple manufacturing method for a security document.
  • the image layer has a first part running laterally in the region of the unit and a further second part running laterally beyond the unit, wherein
  • the first part is arranged along the vertical extent at a first height which is greater than or equal to the determined depth dimension of the unit, and the second part is arranged at a second height which is different from the first height.
  • the invention is based on the consideration that a large part of security documents have a unit which extend into the security document over a substantial part of the thickness of the document along the vertical extension of a security document.
  • the invention has recognized that the image layer in the body of the security document can be arranged at a different height in the area of the unit than in the remaining part of the security document. The height is measured from the surface to which the image layer is assigned.
  • Image layer means any type of layer, for example some kind of information in the form of a printed sheet of paper or plastic can record and is not completely optically transparent. Information here is, for example, colored visible elements represented by letters, numbers or dot patterns.
  • Information can also be recorded through the layer if the spectrum and / or the intensity of the electromagnetic radiation passing through or reflected by the image layer compared to the incident electromagnetic radiation is changed.
  • the term "visible” includes not only the spectrum of electromagnetic radiation visible to the human eye but also information that can be read out by any sensor. This can also include the spectrum of electromagnetic radiation that is not visible to the human eye
  • the image layer may be inherently contained or applied to the image layer by printing, spraying, etc. or be lasered into the image layer. The information can be lasered in before the layer is processed, during the production of the security document or after the security document has been completed on.
  • the first part of the image layer can be assigned to the surface of the security document as an optically effective imaging structure.
  • the unit is designed as an optical security feature.
  • the first part of the image layer can also serve to cover the back of a cavity provided for a chip module in the security document.
  • the first part extends laterally at least partially in the area of the unit.
  • the second part extends at least partially laterally beyond the unit.
  • the first and the second part are arranged at a different height along the vertical extension of the security document.
  • the image layer runs laterally in the area of the unit in a different plane than laterally beyond the unit. This is achieved in that the first part and the second part of the image layer are offset from one another in steps.
  • the invention has recognized that the layer arrangement in the body of the security document in the area of the unit can be rearranged across the surface with respect to the image layer.
  • a security document of the proposed type can be produced particularly easily in a manufacturing process explained below
  • the invention provides that the first part of the image layer is arranged along the vertical extent at a first height which is greater than or equal to the determined depth dimension of the unit
  • the second part of the image layer is arranged at a second height that is lower than the first height. That is, the first part of the image layer is arranged closer to the surface assigned to it than the second part of the image layer. In particular, a second part of the image layer corresponding to the lateral region of the unit is further away from the surface than the first part of the image layer. This proves to be particularly expedient, since the second part set back from the surface is thereby practically on the side of the unit for the lateral region limited necessary area.
  • a particularly preferred embodiment of the security document provides that the image layer is formed in one piece.
  • the image layer can be formed in one piece by only partially separating the first part of the image layers from the second part of the image layer. This can be done in a variety of ways. Further developments that are particularly easy to implement in the course of the manufacturing process are explained in the course of the process
  • optically permeable layer which is preferably formed in one piece. Similar to the image layer, this can be achieved in particular in that a first part of the optically transparent layer is only partially separated from a second part of the optically transparent layer
  • the unit is in the form of an optical structure, in particular a tilted image.
  • the depth dimension is essentially determined by the focal length of the optical structure.
  • the unit can also be in the form of a data carrier, in particular in the form of a chip module.
  • the chip module can additionally have elements for contactless data transmission, for example an antenna the depth dimension is essentially determined by the thickness of the data carrier.
  • the concept proposed here proves to be particularly advantageous, in particular if a first and a second unit are to be arranged on opposing surfaces of the security document.
  • the security document has a first and a second surface, wherein the first surface is assigned a first unit, a first optically transmissive layer and a first image layer.
  • a second unit, a second optically transparent layer and a second image layer are assigned to the second surface.
  • the security document is structured at least with regard to one of the surfaces and the units and layers assigned to it, as explained above.
  • At least one of the image layers has a laterally extending first part in the region of the respective unit and a further laterally extending second part beyond the respective unit, the first part being arranged at a first height along the vertical extension, which is greater than or equal to the determined depth dimension of the respective unit, and the second part is arranged at a second height different from the first height.
  • the security document can be constructed both with regard to its first surface and the unit and layers assigned to it and with regard to the second surface and the unit and layers assigned to it, as explained above.
  • the at least one layer of the optically transmissive layer is arranged between the first and the second image layer.
  • the at least one layer is preferably accommodated in the middle of the security document and is assigned to the first and / or the second surface.
  • the security document bears a first unit on the first surface and bears a second unit on the second surface
  • the first unit is in the form of an optical structure
  • the second unit is in the form of a data carrier is.
  • both units could also be formed in the form of a data carrier or both units could be formed in the form of an optical structure.
  • the security document with two units explained above can be configured particularly advantageously in comparison to conventional security documents, in the event that the sum of the depth dimensions of the first and second units is greater than or equal to the thickness dimension of the security document.
  • the first image layer is in the form of a front side and the second image layer is in the form of a rear side of a single, one-piece image layer assigned to the first and second surface. That is, instead of providing an image layer separately for the first and second surface, it is it is also possible to provide a single image layer for both surfaces
  • the object is achieved by the invention by means of a method for producing a security document of the type mentioned in the introduction, in which an image layer assigned to the surface, which has a first and a second part, is provided first, and furthermore an optical one assigned to the surface transparent layer, which has a first and a second part, is provided in each case the image layer and the layer are formed in one piece and the first part is only partially separated from the second part. Then the image layer is arranged over the optically transparent layer in such a way that the the first part of the image layer comes to lie over the first part of the optically transmissive layer.
  • the first part of the image layer and the first part of the layer are then pushed past one another, so that the first part of the image layer is below it Most part of the layer comes to rest
  • the first part and the second part of the image layer are arranged at different heights along the vertical extent
  • the main advantage of the production method proposed here is that the security document can still be built up in layers over the entire surface, as is the case with security documents of the usual type, as a result of the fact that the image layer and the layer are formed in one piece and the first part only partially from the second Part is separated, it is possible as part of the manufacturing process to shift the height of the layers in the body of the security document to a height position required for the design of the unit to be used. This is achieved in that the first part of the image layer and the first part of the layer are pushed past one another, so that the first part of the image layer comes to lie below the first part of the layer.
  • a first further layer is arranged above the image layer and a second further layer is arranged below the layer.
  • this is achieved by pressing two mandrels from two opposite sides onto the first part of the image layer and the first part of the layer and pushing the two overlapping first parts past one another.
  • the arrangement of the first and the second further layers can take place in the context of a lamination process.
  • the layers can already be connected to one another permanently or initially only for the purpose of the production process, eg. B. by stapling in the edge area.
  • the method proposed above provides that the image layer and the layer are each formed in one piece and the first part is only partially separated from the second part. This can be done in different ways. It proves to be particularly expedient within the scope of the method proposed here that the first and the second part are separated along a dividing line and connected to one another along a connecting line, the dividing line and the connecting line forming a closed line.
  • This line can have an irregular shape.
  • a geometric shape is particularly expedient, in particular the shape of a rectangle.
  • the line can also be used to create a circular shape.
  • the arrangement is selected such that the connecting line of the image is advantageously Layer and the connecting line of the optically transparent layer opposite.
  • the connecting line of the image is advantageously Layer and the connecting line of the optically transparent layer opposite.
  • the image layer is advantageously arranged over the optically transparent layer in such a way that its first parts largely overlap.
  • the image layer is preferably arranged above the optically transmissive layer in such a way that the first part of the image layer comes to lie congruently with the first part of the optically transmissive layer.
  • the method proposed above is particularly expedient to use in the event that the first further layer is a surface layer and in particular forms an optically transparent layer together with the layer.
  • a microlens structure for example, can be introduced into this surface layer in the lateral area of the unit, which then forms a security feature together with the first part of the image layer lying at the first height as an optically effective structure.
  • the second further layer is a second image layer.
  • a second image layer can preferably be assigned to a second surface of the security document.
  • a further optically transparent surface layer is arranged below the second image layer.
  • a further unit for example a cavity for a data carrier, can then be introduced into the security document in the second surface layer.
  • a first image layer assigned to the first surface is offset in the area of a unit arranged on the first surface in comparison to the second part of the image layer.
  • the second image layer is offset in a first part in the area of a second unit assigned to the second surface compared to the second part of the second image layer.
  • a security document can thus be produced that is largely made up of optically transparent layers and has one or more units that take up a not insignificant specific depth dimension. Nevertheless, a security document produced according to such a method can be comparatively thin in its final thickness dimension. In addition, with such a security document, one or more units can be arranged on opposite surfaces of the security document without one of the units being able to be seen from the respectively opposite surface.
  • Such a security document with two units can be compared particularly advantageously to form customary security documents, in the event that the sum of the depth dimensions of the first and second units is greater than or equal to the thickness dimension of the security document t This is achieved by the rearrangement of the image layer and the layer in the lateral region of such a unit, which is proposed according to the manufacturing process
  • the invention proves to be particularly useful for application to a plastic card built up in layers, for example using foils, which can be used in a wide variety of areas as a security document, for example in cashless payment transactions or as an identification card, for example for an identity card or Driver's license Nevertheless, the concept described here is also useful in other applications related to other types of security documents

Abstract

Souvent, la configuration habituelle d'un document de sécurité et une profondeur définie d'une unité montée dans ce document de sécurité résultent en un aspect défavorable ou en une épaisseur trop grande dudit document de sécurité. L'unité peut se présenter sous la forme d'une structure optique ou d'un module puce. Un tel document de sécurité (1) usuel présente une longueur latérale et une longueur transversale par rapport à celle-ci, ainsi qu'une surface (13, 15) qui s'étend sur la longueur latérale et une couche image (23, 25) qui est associée à cette surface (13, 15) et est placée sous une couche optiquement transparente. La surface (13, 15) comporte une unité (3, 17) pour laquelle une certaine profondeur (B1) est prise en compte et qui s'étend sur la longueur transversale pour pénétrer dans la couche optiquement transparente. On obtient, grâce à l'invention, une configuration, avantageuse sous plusieurs aspects, du document de sécurité (31) présenté, par le fait que la couche image (41, 75) présente une première partie (51, 77) s'étendant latéralement dans la zone de l'unité (43, 63) et une seconde partie (53, 79) s'étendant latéralement à l'extérieur de l'unité (43, 63). La première partie (51, 77) est disposée sur la longueur transversale (35), à une première hauteur (55) qui est supérieure ou égale à la profondeur (B1, B2) définie de l'unité (43, 63), et la seconde partie (53, 79) est disposée à une seconde hauteur (57), laquelle est différente de la première hauteur (55). L'invention concerne également un procédé particulièrement avantageux pour la production d'un tel document de sécurité (101).
