Definitions
- the invention relates to a security document with a flat extended
- Composite body which is composed of several substrate layers.
- Security documents are all those documents which have at least one feature that makes it difficult and / or impossible to copy, falsify or duplicate or unauthorize the document.
- Security documents include, for example, ID cards, driving licenses, passports, identity cards, access cards, but also credit cards, postage stamps, shares, visas and the like, to name but a few.
- ID cards for example, ID cards, driving licenses, passports, identity cards, access cards, but also credit cards, postage stamps, shares, visas and the like, to name but a few.
- Verification is understood to mean checking the feature for authenticity and / or integrity.
- the recording medium has an upper layer which has on its outer side a plurality of lenticular lenses and on the back a display element which appears to be movable about at least one axis when the recording medium is tilted.
- the lenticular lenses extend over only a portion of said outside.
- the presentation element is a security element printed on an inner card layer.
- Such appearing display elements are known from the prior art in the form of tilting images or as so-called CLI and MLI security features in which a document body in focus areas of the lenticular lenses is marked by lenticular lenses with the aid of laser radiation. It is possible for different directions of irradiation different information in the
- CLI Changeable Laser Images
- Paper base are made, assembled into a book or book.
- An example of this are passport books with a passport formed as a composite body.
- the plastic materials used to form the composite usually have no sufficient elasticity and bending or bending capabilities to be able to be integrated directly into a passport book like paper pages.
- the booklet has several sheets between an envelope and each sheet has a front and a back. At least one data page is provided which is firmly connected to the envelope.
- the data page has a flexible layer and this flexible layer protrudes with an area out of a data carrier. In this area, the data page is connected to the envelope and the remaining sheets.
- the flexible layer is connected in a planar manner with at least one further layer, for example, by welding or gluing and thus permanently connected without a mechanical connecting part.
- the insert sheet consists of at least one layer of a thermoplastic elastomer and at least one further layer.
- the at least one further layer extends in the direction of the insert sheet plane substantially from the side opposite the seam to the hinge region and the at least one layer of the thermoplastic elastomer extends into the hinge region.
- the layers forming the insert sheet are laminated together.
- thermoplastic elastomer thermoplastic polyurethane (TPU) is proposed.
- High-temperature-stable plastics for example polycarbonates (PC), are proposed for the at least one further layer.
- the personalization of the insert sheet which is a composite of several layers, takes place in the high temperature stable plastics.
- thermoplastic elastomer insert sheet and at least one further layer of a high-temperature-stable plastic such as polycarbonate (PC) laminated therewith
- PC polycarbonate
- the personalized PC layer can be almost undamaged by the thermoplastic
- Solve elastomer formed layer This is very disadvantageous with regard to the forgery-proof passport.
- a non-destructively releasable connection is understood in the following to mean a connection between two layers which is not resolvable without causing damage, in particular at the layer provided with the higher melting temperature.
- PC polycarbonate
- TPU thermoplastic elastomer thermoplastic polyurethane
- thermoplastic polyurethane TPU completely melts, which is detrimental to its dimensional stability. Therefore, laminates between thermoplastic elastomers in high temperature stable thermoplastics in normal lamination processes are not of sufficient quality to ensure a non-destructively releasable bond in any case, as practice has shown.
- the invention is based on the idea of creating novel security documents which use a textile as part of a composite body. An heightened
- Composite body of the security document is arranged so that the textile is superimposed with a visually detectable representation of the security document or overlay and cooperates with that through the top of the
- Compound image can be detected, the contents of which depend on a detection direction relative to the top of the composite body.
- a detection direction relative to the top of the composite body.
- a representation is designated, of which an image can be detected with an imaging method and by means of a
- a pictorial representation, ie graphical representation, of information is referred to as an optically detectable representation, from which an optically executed image can be detected, for example with a camera or with the eye, and from the image the information shown can be extracted.
- An optically detectable Representation can be formed for example by printing on a substrate.
- the optically detectable representation can also be stored in a hologram, and becomes perceptible and detectable only during the reconstruction of the hologram.
- a graphical representation of information printed by means of luminescent colors may not be visible under illumination with light in the visible wavelength range, but optically detectable and perceptible under illumination with UV light and thus represents an optically detectable representation.
- every pictorial representation is understood. This also includes characters, symbols, pictograms, graphs, images, but also line patterns, such as guilloches, or intersecting lines, etc., to enumerate a few examples. This list is only exemplary and not exhaustive.
- a security document which has a surface
- Bottom side which is composed of at least two substrate layers, and comprises a formed from filaments textile, of which at least a planar portion between the at least two substrate layers is arranged, wherein at least one optically detectable representation is arranged in the security document, which at least part of the between the at least two substrate layers arranged portion of the textile is covered or überdeckbar, wherein the textile and the at least one optically detectable representation are formed so that a detected by the top of the composite body mapping of the superposition of at least a portion of the portion of the textile over the at least one optically detectable representation is dependent on a detection direction relative to the top of the composite body.
- the textile is formed as a fabric.
- the textile is woven so that the threads preferably provide rectangular or square grid basic elements. It can also be formed diamond-like grid basic elements.
- an advantage of using a textile, in particular a fabric is that in a lamination process, those formed in the fabric
- Substrate layers can be formed. It is thus possible to choose the threads of the textile from a material which has a higher temperature resistance than the materials which are directly adjacent to the textile in the composite body and are preferably welded or laminated together.
- the threads of the fabric are for a wavelength range of the optical spectrum, preferably for the entire Wavelength range of the optical spectrum, which is perceptible by a human observer, formed opaque.
- the grid of the textile is usually visible optically without or in addition to the moire effect, which is perceptible by the overlay with the graphic grid of the at least one optically detectable representation.
- the threads of the textile are transparent to at least a wavelength range of the optical spectrum that is detectable by a human observer, preferably for the entire wavelength range that a human observer can detect.
- the viewer does not usually perceive the textile grid as a stand-alone grid or pattern of the composite or security document. For the viewer is therefore not immediately obvious how the viewing direction dependent or
- the textile is provided with a tab portion over edges of the at least two substrate layers of the composite body, between which the textile is arranged with the one section, and the tab portion is combined with other book pages to form a book.
- a book-trained security document is a passport or the like.
- Textiles have proven to be particularly suitable, which are made of plastic threads.
- textiles are based on polyester threads.
- the threads of a polyester material have a higher
- Substrate layers Polycarbonate-based (PC) layers and films, but also other thermoplastics such as ABS, polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethersulfone (PES), polyetherketone (PEEK), polyphenylene oxide (PPO),
- PC polycarbonate-based
- PVC polyvinyl chloride
- PET polyethylene terephthalate
- PET polyethersulfone
- PEEK polyetherketone
- PPO polyphenylene oxide
- Lamination can be selected to form a stable tamper-resistant composite body, as is otherwise necessary in integrating a Lasch enabitess or other portion of a plastic component in a composite body.
- inventions are also useful in which the textile does not protrude beyond edges of the remaining substrate layers joined to the composite body.
- the textile can be integrated into the composite body so that it is arranged over the entire area between the upper side and the lower side of the composite body.
- a textile-free edge exists. This significantly reduces the risk of delamination attacks.
- a textile section is arranged on a substrate layer around which a peripheral edge of the substrate layer remains uncovered. At least one further substrate layer is then arranged on this substrate layer and a composite body is produced, for example by means of a lamination process.
- Compound body extends.
- the at least one optically detectable representation is arranged in the composite body itself and at least part of the optically detectable grid of the at least one optically detectable representation of the at least a portion of the disposed between the at least two substrate layers portion of the textile is covered.
- the optically detectable representation against counterfeiting is likewise particularly well protected, since it is in the composite body
- the at least one optically detectable representation is formed on another component of the security document.
- trained security document can thus be carried out on the inserted into the composite textile in cooperation with an educated on a passbook page optically detectable representation of a review of the security feature, which is formed by the interaction of at least one optically detectable representation and the textile.
- the composite body comprises a preferably opaque substrate layer having a recess in which the portion of the textile is arranged, which is arranged between the at least two substrate layers.
- a see-through window can be created in the composite body.
- the insertion of the textile into a recess is one between the at least two
- Substrate layers arranged further substrate layer advantageous because due to the additional textile material a composite strength increase is avoided.
- Composite bodies can be created in which the textile does not protrude beyond an edge of the at least two substrate layers, between which the textile is arranged. There are thus also card-shaped security documents useful with a textile equipable, no tab section for incorporation into a book-like
- Detection direction relative to the top is obtained in embodiments in which the at least one optically detectable representation perpendicular to the planar extension of the arranged between the at least two substrate layers portion of the textile is spaced therefrom.
- An increased distance in this case leads to a stronger directional dependence of the detected Moire pattern in the superimposition of the textile grid and the graphic grid.
- a transparent substrate layer is thus arranged between the textile and that substrate layer on or in which the at least one optically detectable representation is arranged or formed.
- the optically detectable representation can be formed, for example, in the form of a grid comprising fine lines.
- the at least one optically detectable representation by means of a printing process on a
- Substrate layer surface which is preferably arranged after a lamination step in the interior of the composite formed.
- a grid is stored, which contributes to a detection through the section of the textile through to a moire effect.
- the hologram is
- Reconstruction light can be made over the top of the composite, over which also a detection of the image is made. In other embodiments, it may also be a
- Transmission hologram act in which an exposure to the reconstruction by a bottom of the composite body.
- the optically detectable representation is structured in a contiguous display area by means of graphical structural elements, wherein by means of the structural elements information is encoded and the optically detectable grid is not the entire area in the contiguous display area, but only in one Representation area of a structural element or in the display area of several of the structural elements is formed.
- the structural elements in one embodiment may include, for example, alphanumeric characters, pictograms, or even a silhouette or a silhouette of a profile of a facial image or the like.
- the moiré effect is then visible only in the area of the graphic structural elements, the information of which is then still undisturbed and can still be detected, but is modified with regard to a graphic or pictorial appearance by the detection direction-dependent effect.
- a use of a grid is not the only possible embodiment of the optically detectable representation to effect a detection direction-dependent effect, which is achievable in the interaction between the textile and the at least one optically detectable representation.
- at least a part of the threads of the textile, in particular of a fabric be transparent and with regard to the thread cross-sections such that the threads act to focus light in the visible wavelength range, if they are between
- Plastic materials are introduced, which have a different refractive index of the refractive index of the thread material.
- the threads of the fabric consist of a transparent plastic material which has a refractive index which is of the refractive index of a directly adjacent to the textile Substrate layer or differs from the refractive indices of the two immediately adjacent to the textile substrate layers and the threads have a cross-sectional shape, so that focus light at least one wavelength when passing through and the at least one optically detectable representation or another optically detectable representation for at least one of the detection directions in
- Focal regions of the threads include CLI markings for a first CLI mark.
- additives may be added to one of the substrate layers which promote absorption of laser light of a wavelength used for imprinting the CLI marks. These additives are usually designed so that they do not affect a transparency of the substrate in the unexposed state or not appreciably perceptible.
- An imprinting of the CLI markings then takes place in the composite body, preferably by means of laser light, the intensity of which is chosen so that a significant light absorption, which lead to an optically detectable change in the composite body, take place only in the region of the focal points or focal lines of the threads.
- the at least one optically detectable representation or the further optically detectable representation comprises further CLI markings which can be detected from a detection direction deviating from one detection direction or from a plurality of detection directions deviating from one detection direction and which one or more further CLI information coded by means of the further CLI markings, which deviate from the one CLI information, are encoded.
- the CLI markings between the textile and the graphic grid are particularly preferably arranged in the composite body.
- a particular advantage of using a textile for forming lens elements in a composite body in which the textile is disposed between the substrate layers is also that unstructured smooth lamination sheets can be used in lamination. These are much cheaper and cheaper
- lens elements are arranged in the interior of the composite body and are thus very well protected against damage and manipulation.
- the textile is inserted into a recess of a further substrate layer whose material thickness is adapted to a material thickness of the textile.
- Composite body can be applied. These layers do not affect the security feature of the invention.
- a hologram or protective lacquer can be applied to this surface, since the lens structure would be impaired in the process. This disadvantage is eliminated in the embodiments proposed here.
- a flat, smooth surface of the composite body can usually be achieved even if the textile is not introduced into a recess of a substrate layer. Often, however, higher temperatures and / or pressures are needed to form such a smooth surface, particularly in textiles having a high thickness.
- a small layer thickness of the textile is selected, preferably 10 ⁇ to 150 ⁇ , more preferably 60 ⁇ to 130 ⁇ .
- a substrate layer into which the textile is introduced may be transparent or translucent. In many cases, however, the substrate layer becomes opaque be formed so that a see through window, at least through the opaque
- Substrate layer created at the point of the textile.
- the composite body is formed so that below a continuous from the top of the composite body contiguous area, which coincides with the at least part of the portion of the textile between the at least two substrate layers covering the at least one optically detectable representation or with the an optically detectable representation can be covered, consists of base material that is transparent in the volume, or consists of base material that is transparent in the volume, at least between the top side and the optically detectable representation.
- optically detectable representation Interaction of the optically detectable representation and the textile in the optically captured images is detectable.
- transparent base material is understood as such material, through which an optical imaging in accordance with the laws of geometric optics is possible.
- the material can have a color and thus absorb light of individual wavelengths in the visible range and transmit only light of specific wavelengths.
- individual markings for example CLI markings in the form of blackening, are formed.
- individual printed layers may be formed in the material, which, however, may not be formed in a coherent, continuous manner in such a way that they make a geometric imaging through the printed layer completely impossible.
- a textile for forming a security feature even without performing a function as a hinge or tab element, can be used in a composite body.
- textiles with different thread sizes and / or made of different materials can be used to lenses with different focal lengths produce. Such an effect can also be achieved if different threads are processed together in a textile.
- the textile is not a woven fabric but, for example, a nonwoven fabric
- storage of CLI markings is quasi random due to the "disordering" of the fibers in the nonwoven fabric and is not reproducible, but the information encoded by the CLI markings may be due to the nonwoven fabric is integrated into the composite body as a textile, be read out again.

- Fig. 8 is a schematic representation of graphical structural elements.
- Fig. 1 is schematically a security document 1 in the form of a passbook 2 schematically illustrates.
- the passbook 2 comprises a composite body 3, which is joined together with passbook pages 5, 7, 9 and a passport cover 1 1 to the passport book 2.
- the assembly is carried out via a binding 19, which is indicated schematically here.
- any known in the art and training method for assembling a passbook can be used.
- a thread binding using a metal wire or the like may be used.
- the passport cover 1 1 comprises an upper passport cover 13 and a lower passport cover 15, which are connected to each other via a passport spine 17 and are preferably formed in one piece. In the illustrated embodiment, the upper passport cover 13 is opened.
- the composite body 3 is in the illustrated embodiment of an upper
- Section 43 of the fabric 41 between the upper substrate layer 35 and the lower substrate layer 37 are arranged.
- Substrate layer 39 and lower substrate layer 37 and portion 43 of textile 41 disposed between upper substrate layer 35 and lower substrate layer 37 are bonded to composite body 3 in a lamination process.
- the textile 41 is preferably formed as a fabric.
- the textile may also be a knit, provided that this forms a regular textile grid 47 analogous to that which form the threads 45.
- the threads 45 may be both opaque and opaque to light in the visible wavelength range.
- the textile grid 47 is a regular grid in which by warp threads 45-1 and weft threads (not shown) square or rectangular grid units are formed.
- an optically detectable representation 61 in the form of a graphic grid 63 is printed on the passbook page 5.
- the arrangement of the graphic grid 63 is selected relative to the section 43 of the textile 41 such that the textile grid 47 overlays the graphic grid 63 in a planar manner.
- an overlap with respect to a viewing perpendicular to the upper side 31 of the composite body 3 is considered as a planar overlay. This means that whenever one
- the graphic grid 63 is formed, for example, in the form of lines which extend perpendicular to the plane of the drawing. Corresponding to this parallel, for example, the illustrated warp threads 45-1 of the textile 41 are oriented in the section 43.
- the textile grid 47 has a grid spacing 48 between the warp threads 45-1, which is slightly different from a grid spacing 68 of the graphic grid 63.
- the moire pattern 151 of FIG. 150 also changes. This ensures that the textile 41 is integrated into the composite body 3.
- the grid 63 may also have equally spaced further lines formed on the passport page 5 and oriented transversely, preferably perpendicularly, to the lines perpendicular to the plane of the drawing , A grid spacing of the further lines can correspond to the grid spacing 68 of the lines running perpendicular to the plane of the drawing. In other embodiments, the pitch of the further lines deviates from the pitch 68 of the vertical to the drawing plane extending lines.
- the grid 63 may consist only of a group of parallel lines that are equally spaced, as shown in FIG.
- another optically detectable representation 71 is formed in the form of CLI markings 73, which are shown schematically in the form of letters "A".
- the CLI markings are formed into an optically detectable image of the letter A through the threads 45 of the textile 41. This results in addition to a CLI feature, so another viewing direction-dependent or by a
- Detection direction 173 dependent security feature in which information, here schematically represented as "A”, can be coded.
- FIG. 2 shows a further embodiment similar to that of FIG. 1. Same technical features are in all figures with the same reference numerals
- FIG. 2 differs from that of FIG. 1 in that in this embodiment the graphic grid 63 of the at least one optically detectable representation 61 on a material layer in the interior of the
- Composite body 3 is formed, which corresponds to substrate layer boundaries of the lower substrate layer 39 and an additional substrate layer 38.
- the additional substrate layer 38 is connected to the upper substrate layer 35 of the lower
- the at least one optically detectable representation 61 is preferably printed in the form of a graphic grid 63 on one of the substrate layer surfaces. This can for example be done during a printing process, with the other
- Security features are printed on one of the substrate layer surfaces. These other security features are not shown here for the sake of simplicity and are of course formed in the composite body 3 or in the passport pages 5, 7, 9.
- a security document 1 is shown, which is in the form of a plastic card formed as a composite body 3.
- no portion of the fabric 41 projects beyond the edges 135, 137 of the top and bottom substrate layers to form a tab portion.
- the middle Substrate layer 39 is opaque in this embodiment.
- a first optically detectable representation 61 is formed in the form of a graphic grid 63, which is formed by any marking method, for example a printing method, in which one of the substrate layers is prior to assembly
- a substrate layer surface is printed, which forms a material layer in the interior of the composite body 3.
- the material threads have a higher refractive index than the material of the adjacent substrate layers 35, 37.
- multiple CLI markers 73, 75 are different CLI information "A", "B" shown schematically.
- the CLI markings 73, 75 are in each case for a detection direction 173, 174 in a focal line of one of the threads 45 of the textile 41. Under the detection direction 173, the CLI information A is detectable, under the detection direction 174, the CLI information B. In a central plan view along the detection direction 171, however, only a moiré pattern 151 is detected, which by the superposition of the textile grid 47 on the graphical grid 63 is created. Upon variation of the detection direction 171, the detected image 150 and hereby the moiré pattern 151 changes.
- FIG. 4 shows a further embodiment, in which, unlike in FIG. 3, the first optically detectable representation 61 is designed in the form of a hologram 80, in which an optically detectable grid is reproduced during a reconstruction of the hologram.
- This forms in the superposition with the textile grid 47 again a moire effect in a captured image 150, wherein this is dependent on the detection direction 171.
- the directional dependence is not due to a directional dependence of the hologram 80, but is due to a change in the parallax between the textile grid 47 and the graphic grid 63 of the hologram 80 reproduced during the reconstruction. This is so
- This grid consists for example of groups of lines that intersect at right angles or at another angle other than 90 °, the lines of a group each having a constant distance to the adjacent line of their group, and thus, for example, diamond-shaped, form rectangular or square grid basic elements. If a grid has three groups of lines, triangular grid primitives can also appear.
- the grid may also consist of a group of equally spaced parallel lines.
- a grid can also be formed from regularly arranged similar geometric shapes, such as circles, dots, etc. Such a grid can be generated, for example, in which the geometric figures are arranged at points of intersection of an assigned (but not graphically represented) grid formed by lines.
- Fig. 5 is a schematic plan view of a composite body 3 for insertion into a passport document is shown.
- the graphic grid 63 is indicated by dashed lines.
- Tab section 49 of the textile out In a section 35 of the textile 41, this is arranged between the upper substrate layer 35 and the lower substrate layer 37.
- the section 43 of the textile overlies a graphic grid 63, which is formed for example in the lower substrate layer 37 and is indicated by dashed lines.
- a moiré pattern is formed, which is not recognizable here, since the grid spacings 68 of the graphic grid and 48 of the textile grid 47 are chosen to be very large and too different from each other for clarity. It is essential for the formation of a moiré pattern that the grid spacings 48 of the textile grid 47 and 68 of the graphic grid 63 are not identical but slightly different.
- the orientation of the raster lines, i. the threads and the printed lines of the graphic grid for example, need not be oriented parallel to one another. Even a slight twisting leads to a moire effect, which, however, differs from the moiré effect that results in parallel orientation.
- FIG. 6 schematically illustrates the resulting moiré effect. Shown is a schematic plan view of a security document on which the entire surface of a graphic grid of alternating green and yellow lines is formed. A lower half of the security document 1 is superimposed by a textile which has transparent threads. Good to see is a Moire pattern with a Grid spacing 158, which is much larger than a grid spacing 68 of the graphical grid 63. The slight curvature of the lines appearing in the Moire pattern is due to slight deviations of the linear course of the textile threads.
- manipulations of security documents can be detected.
- manipulations of security documents can be detected.
- FIG. 7 shows a further exemplary illustration of a resulting moiré pattern, which results, for example, in a rotation of an otherwise rectangular textile grid in relation to a graphic grid of vertically extending fine lines.
