Description

The The invention relates to a security and / or value document according to the preamble of claim 1.

Especially Personal documents, banknotes, securities, certificates, service cards, such as credit cards or the like, postage stamps, general products, which must be authorized are often produced in a process easy nachzustellenden.

It is desirable for these products, To provide evidence of their authenticity, d. H. of their originality enable.

The Security features should be as inseparable be associated with the product to be authorized and / or properties which are difficult to reproduce.

The Manufacture and use of security features in security and / or securities are generally state of the art.

It is a variety of security features known as fluorescent Fibers / planchettes / colors, micro-typefaces, moiré-producing structures, holograms and the like ..

When Security feature are often in the product to be protected special colors with spectral features or with magnetic properties or with temperature dependencies (thermochromic colors) introduced. Barcode is used, where the reflectivity differences of the surface is exploited, or it will be grid structures or film antennas used to exploit the resonant frequency in a resonant circuit.

From the AU 488 652 B and security documents known in which security features can be checked by means of transmitted light inspection. Between plastic sheets an optically variable security element is arranged, which can be viewed through a transparent window in the overlying cover sheet. It is disadvantageous in particular that the attached security features are visible only in the process by light with the naked eye, and that the material properties of the document are greatly changed.

It is also the introduction of only a transparent window in banknotes known as a security feature (Australian banknotes).

In the DE 43 34 847 A1 is described a document of value with window in which the carrier is subsequently provided with a window-like opening, which is closed with a transparent cover, wherein the cover is provided in this area of the window with additional security features. The preparation of the subsequent breakthrough of the carrier of the security to a window and the cover with a transparent cover, which in turn is partially provided with a security feature, is technologically complex and has an increase in the thickness of the security result. The requirement that areas of the window must remain transparent in order to be able to recognize the security features in the transmitted light method with the naked eye restricts the possibilities of concealed security features. These are just as in the known window threads in banknotes to elements, which are used in themselves only as a security element, but do not take on any other function. The known windows, taken alone, can also include security features.

The authentication the known security features usually requires the use of special devices, methods and in particular of external ones Testing equipment such as Magnifying glasses for checking Micro-typefaces, lenticular for verification of hidden, graphic Elements, UV lamps for visualizing fluorescence, or in the transmitted light method, the optical recognizability of the security feature.

In the DE 36 09 090 A1 is a security with embedded embedded security thread, which is visually verifiable without technical aids. The security thread is made of a transparent material. On a surface a grid of cylindrical lenses is imprinted. On the opposite surface of the film of the thread directly a printed image is applied. The printed image is designed taking into account the optical properties of the cylindrical lenses. By appropriate design of the printed image so that information can be introduced, which are visible only from certain angles.

adversely is that directly is arranged under the thread of paper, so that the security feature only in reflection and not in transmission can be considered. The safety is only in the thread. The thread is a common one Safety element.

In the EP 256 176 A1 For example, a security document, such as a passbook, which has a certain "irregular indicia" in one part of the document and a reading screen in another part, is read to read the indicia. At a A signature can be read on top of each other.

In the EP 930 979 B1 , which is an older copending application, discloses a token document having a self-check unit that includes a portion of a transparent plastic material that can be used to check the security document when the document is being bent or folded. However, a verification and / or security element according to the present invention is in the EP 930 979 B1 not revealed.

In the DE 43 34 847 A1 a document of value is disclosed in which a carrier is provided with a window-like opening which is closed by a partially transparent covering film. This cover film can be provided in particular in the region of this opening with additional security features such as diffraction structures. However, a verification and / or security element according to the present invention is in the DE 43 34 847 A1 also not disclosed.

Of the Invention is based on the object, a generic safety and / or document of value, in which the security against counterfeiting elevated and the simplified exam Guaranteed document authenticity without external means are.

The solution This object is apparent from the features of the claim 1. By providing security features and verification means like detectors to verify the security features on or in a document is achieved that no external aids to check the Authenticity of the document needed become. It can be the authenticity for example, on a banknote security features by, for example, one or more transparent windows be checked on the same banknote. The combination of security features and a verification system raised on the same banknote their forgery security, because the verification system is also a security feature can be configured. To check the Authenticity can the show and back the banknote to be used. By suitable folding of the banknote or any other document required by law of the invention, or by superimposing several banknotes, a security feature can be checked by using the security feature with the verification system, e.g. B. Window, brought into effect.

It can with the verification element applied to the value document security features introduced at various points in the document.

In a passport can for Example two opposite Pages serve to verify the document. This can be a page with the verification element, the other side with the analyzer Security feature, be provided. By suitable overlapping the authenticity is checked. As well can two banknotes, checks or two other identically designed value documents be checked for authenticity.

critical is the functionality the window or windows integrated in the document. It essentially becomes no additional Thickness of the document generated as the detection means and the security features are arranged on a document at different locations and not on top of each other.

The preferably forming the verification element as a detector / analyzer or decoder in the form of one or more transparent windows or even a window with several analyzer areas with detection elements guaranteed a variety of variants to verify the authenticity a variety of possible Security features.

The Verification elements on / in one or more windows or in areas of a window are preferably of a clear, transparent material.

The Verification elements are preferably polarizing filters educated.

Prefers Two clear windows are arranged next to each other or a window is divided into two analyzer areas.

The Windows can as two polarizers for the observation of polarization stereo images to be formed.

It can be achieved that at least a specially shaped window forms a "Polaroid Vectograph".

• – Die hellen und dunklen Bereiche eines Bildes sind linear polarisierende Bereiche mit abwechselnd horizontaler und vertikaler Polarisationsrichtung.

It can windows for realizing a contrast envelope are formed between transmissive and impermeable. Such structures can be realized by applying lambda-half regions to a linearly polarizing film, for example by suitably oriented films of the correct thickness:

• The light and dark areas of an image are linearly polarizing areas with alternating horizontal and vertical polarizations direction.

It can Windows are shaped, which give a clear color change after the Principle of "color Shutter "realize.

Further advantageous embodiments of the invention will become apparent from the Dependent claims.

4 the schematic representation of a banknote with windows on a corner.

As shown in the 1 is a value document, for. B. a banknote 1 , with a transparent window 2 formed, which is used by the equipment with verification elements as a detector or the like. To a security feature in one area 3 the banknote 1 to verify. The verification of the security feature in the area 3 the banknote 1 takes place for. B. by the superposition of the two areas 2 and 3 ,

In one embodiment, a polarizing filter on / in a preferably transparent film material as a verification element in the area 2 , z. B. a banknote 1 , in combination with another similarly designed polarizing filter in the range 3 integrated. The polarization filter in the range 3 is preferably perpendicular or parallel to the polarizing filter in the range 2 designed and acts as an analyzer, so that by appropriately superimposing the areas 2 and 3 the banknote 1 and rotation of the superimposed areas 2 and 3 against each other, the optical transparency (light / dark) changes or changes.

A further embodiment is formed by applying to one of the two polarizing filters in the areas 2 . 3 an additional dichroic (birefringent), graphically structured layer, e.g. B. by printing, sputtering, casting and the like., Applied, so that by suitably superimposing the areas 2 . 3 the banknote 1 and rotation of the superimposed areas 2 . 3 against each other, a graphic element, eg. As a font, is visible.

Another embodiment is achieved by placing one of the two polarizing filters in the areas 2 . 3 is replaced by a reflective layer, wherein additionally a dichroic, graphically structured layer is applied to this reflective layer. By suitable overlapping of the areas 2 . 3 the banknote 1 and rotation of the superimposed areas 2 . 3 against each other is a graphic element, eg. As a font, visible.

A further embodiment provides for replacing one of the two polarization filters with a reflective layer, wherein additionally a dichroic, graphically structured layer is applied to this reflective layer. This birefringent transparent layer may preferably be formed from a liquid crystal-containing film. By suitable overlapping of the areas 2 . 3 the banknote 1 , z. B. by folding, and by rotating the superposed areas against each other is a graphic element, for. As a font, visible.

For many verification effects, it is desirable to easily and quickly bring two different types of verification elements across the security feature. This often facilitates the perception of a change in the case of movement or color shift effects. It facilitates verification in cases where rotation of the verification element relative to the security feature is required. Such a rotation would be at a single verification window 2 very impractical. To solve these problems, the distribution of the verification window will be used 2 into two adjacent analyzer areas ( 2 . 2a to 2d ) or the arrangement of two adjacent windows 2 ( 3 ) proposed with different verification elements.

In the 2c is an embodiment of a window 2 shown as a verification element, on the banknote 1 as verification elements at least two clear analyzer areas 5 . 6 side by side as a window 2 are arranged.

An embodiment according to 2a provides that the at least two adjacent clear analyzer areas 5 . 6 in a window 2 are designed as a so-called "Vectrograph". A "Vectograph" consists of two superimposed laminated polyvinyl alcohol films which form linear polarizing filters when printed with iodide inks. The two films are oriented such that the front surface forms a vertical polarization upon contact with the iodide color and a horizontal polarization upon contact with the iodide color (FIG. 2a . 2 B ). On the front sheet is selected with iodide color a selected first pattern, eg. For example, a square 10 ( 2a . 2 B ), and on the back a selected second pattern, e.g. B. a star 11 ( 2a . 2 B ), printed. Looking at the superimposed films with a linear analyzer (window 2 , Area 5 of the 2a . 2 B ) appears when the analyzer is oriented horizontally 5 the first pattern (square 10 ) and with a vertical orientation of the analyzer 6 the second pattern (star 11 ). Likewise, color changes can be realized.

A shared in this way verification window 2 with analyzer areas 5 . 6 spares the rotation of the window 2 , the window 2 will only be moved.

Similarly shaped areas 5 . 6 can be designed to realize a contrast envelope between transmissive and impermeable. Such structures can be realized by applying to a linearly polarizing film 8th ( 2d ) so-called "lambda-half" areas 9 (Phase plates with a phase shift of 180 ° between ordinary and extraordinary beam), for example, by suitably oriented film materials of the correct thickness can be applied ( 2d ). In these areas, the polarization direction is rotated by 90 °. This effect is particularly impressive with area filling patterns. Similarly shaped structures are used to realize a clear color change on the principle of the so-called "color shutter".

In another embodiment, at least two are clear analyzer regions 5 . 6 as shown in the 2 and 3 arranged side by side. These areas 5 . 6 are formed as at least two color filters for viewing so-called anaglyphs (stereo images), with the anaglyphs on the area 3 the banknote 1 are located. By suitable overlapping of the areas 5 . 6 and 3 at a certain distance from each other a stereo impression is created.

All windows can in any form, preferably in a form that best corresponds to the type of the selected verification element, as well as thread-like or as in the 4 shown is triangular, be formed.

The windows can be placed anywhere on the document, as well as on a corner of the document, as in the 4 shown by way of example only have to fulfill the condition that security features and verification elements for verifying the security feature can be brought into operative connection with one another, for example by folding, twisting, superimposing one or more documents.

The overlapping can be in direct contact or in some cases even at a distance between the security feature and the verification element.
