Description

VALUE OR SAFETY PRODUCT AND PROCESS FOR PRODUCING IT

The present invention relates to a valuable or security product with a single or multi-layered base body, at least one of the layers of the base body comprising a planar upper side and a, in particular parallel to this, preferably also planar underside which is provided with a recess, in particular with a window, which is formed from an edge connecting the top to the bottom. The value or security product is, for example, a (plastic) data card that is used in a passport. Value or security products can be, for example, a personal document, a check card, a personalized authorization card, or a value or security element intended for product security. The invention also relates to a method for producing such a value or security product.

Value or security products, in particular value or security documents, serve to verify the identity of a person or thing or a claim, for example for payment of a sum of money or for the surrender of a product or the provision of a service. For this purpose, it must be ensured that the product cannot be imitated, counterfeited or adulterated, or only with considerable effort. The product therefore contains security features which it is extremely difficult or even practically impossible to copy. For example, like banknotes, the product is made of a material that is not readily available. Additionally or alternatively you can Security features can be formed by special colors, for example luminescent or optically variable colors, optical elements such as tilt images, kinegrams, lenses or prism arrays, and also guilloches, mottled fibers, security threads and others. Furthermore, it is also necessary that the value or security documents can be easily produced and that they can be recognized by visually impaired persons.

Although there are many security features that are used, there are still many counterfeits of valuable or security products, especially those used in passports, that are successful.

It is therefore the object of the present invention to provide a valuable or security product and a method for its production which take into account the disadvantage mentioned above.

This object is achieved with a valuable or security product with the features of claim 1 and with a method with the features of claim 8. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.

The valuable or security product comprises the base body with the recess, the edge of the recess running at least in sections inclined at an angle with respect to a normal to the top or bottom. The recess can also extend over several layers of a multi-layer base body, so that in particular an irregular edge with an inclination by a predetermined or predeterminable angle with respect to the normal of the top or bottom of the card results. There can be different inclinations with respect to the respective normal along the edges. The edge is preferably formed irregularly so that it can itself be used as a security feature. In this context, it is possible that the edge of the recess at a first section is inclined by a first angle with respect to the normal of the top or the bottom, and that the edge of the recess at a second section is inclined by a second angle deviating from the first angle with respect to the normal to the top or bottom. It is thus possible to provide different angles and also different roundings on the recess, so that these make counterfeiting more difficult. The recess then no longer has to be produced with a mere punching tool, as is described, for example, in DE 102014 000 133 A1 or DE 102016201 976 B3 by the applicant. Compared to the punching production, variable cutting contours, that is, shapes for the edge, can be realized both two-dimensionally and three-dimensionally by laser cutting the recess.

According to the invention it is provided that the recess is at least partially, preferably completely filled with a filling. The filling can also be formed from a plastic-based substrate and preferably also cut with a laser cutting device. It is possible to make the filling thinner or thicker in terms of its thickness than the actual recess is formed, so that a depression or an elevation can be felt in the finished valuable or security product. A security feature that can be detected by means of haptics is thus present.

The filling has a, in particular planar, surface and a, in particular, parallel to this, preferably planar, lower surface, the surface being connected to the lower surface by means of a side cheek which is at least partially adapted to the edge of the recess. This ensures that the filling can be inserted into the recess and is at least partially in contact with the edge of the recess. The side wall of the filling and the edge of the recess are designed at least in sections or areas, preferably completely complementary to one another, so that the filling can be inserted into the recess in the manner of a window, i.e. in the “frame” given by the recess. are the edge and / or the side cheek lasered at an angle, this also facilitates the insertion of the filling into the recess.

It is therefore advantageous if both the recess and the filling are based on a laser cut. When punching, burrs are created that can only be removed manually with great effort. The laser cut is burr-free, so that cycle times are reduced and assembly is easier for the production of such valuable or security products.

In addition, in order to increase the protection against forgery, there is the possibility that the filling has a color which differs from the color of the base body or the layer provided with the recess. If the wrong color is inserted into the recess, this can be determined during the check and thus indicates a forgery.

Additionally or alternatively, the coloring of the filling can be adapted to product-specific and / or person-specific information. As an example of person-specific information, the color of the filling can be related to the date of birth, for example to the day of the birthday, if a total of 31 different colors are available and present for the days of a month. Alternatively or in addition, it is possible to specify different colors for the filling in a product-specific manner, so that, for example, the filling of a driver's license is given a different color than the filling of an identity card.

It is additionally or alternatively possible that a contour or the side wall of the filling and / or a contour of the recess are adapted to product-specific and / or person-specific information. For example, it is possible here for the contour or the shape of the filling to reflect the date of birth as person-specific information. For example, a first shape (for example a polygon) for an identity card or a second shape (for example an oval) for a driver's license can be specified on a product-specific basis. Other shapes, depending on the application, can also be used. The valuable or security product is preferably in ID 1, ID 2, ID 3 or in any other format, for example in booklet form, as in the case of a passport-like object. The valuable or security product is generally a laminate of several document layers that are flatly connected to one another, for example under the action of heat and under increased pressure. These products should meet the standardized requirements, for example ISO 10373, ISO / IEC 7810, ISO 14443.

The product layers preferably consist of a carrier material that is suitable for lamination. The valuable or security product can, however, preferably be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminally disubstituted bis (hydroxyphenyl) cycloalkane, polyethylene terephthalate (PET), their derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS) , Polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and their derivatives, and / or paper and / or Cardboard and / or glass and / or metal and / or ceramic.

In addition, the product can also be made from several of these materials. It preferably consists of PC or PC / TPU / PC. The polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque. The above information relates both to films to be joined together and to liquid formulations that are applied to a preliminary product, such as a protective or topcoat. The product is preferably made from three to twelve, preferably four to ten, films. The foils can also have printed layers. A laminate formed in this way can then be coated on one or both sides with the protective or topcoat or with a film. The film can in particular be a scratch protection film. Overlay layers formed in this way protect a security feature arranged underneath and / or give the document the required abrasion resistance. The method according to the invention for producing such a valuable or security product comprises the step of laser cutting by means of a laser cutting device at least one layer of a base body having an upper side and an underside, a recess being produced which is formed by an edge connecting the upper side and the lower side, which runs at least in sections inclined at an angle with respect to a normal of the top or the bottom.

In contrast to the known method and the use of a window punch, a laser is used in the present case to introduce three-dimensional or, in sections, two-dimensional contours into the card-shaped valuable or security product. In addition, the card edge of the value or security product can be lasered at an angle. For individualization or personalization, for example, a diagonally slightly distorted card or a card edge personalized with notches or the like can be lasered. The notches are particularly related to the name on the document.

By using the (plastic) laser cut, the burrs that usually occur during punching can be avoided. Suitable laser protection films also prevent smoke or combustion residues. In addition, appropriate inert gas flushing or suction devices can be present to suck off any smoke or combustion residues, so that the time for post-processing is drastically reduced.

The resulting recess can preferably be filled with a filling, at least partially, but in particular completely. This makes it possible to compensate for any unevenness that arises, with the possibility also being opened up of realizing a tactile security feature through a different thickness of the filling and the layer provided with the recess.

It has proven to be sensible and process-efficient if the filling is cut from a substrate by means of the laser cutting device and the side cheek is formed on the filling, which at least partially adjoins the Edge of the recess is adapted. Preferably, however, the side cheek is formed complementary to the edge of the recess, so that the filling can be inserted into the recess with an accurate fit. With a suitable inclination of the side cheek and / or the edge, it is also easier to insert the filling, and therefore the pill, into the recess. If the side cheek and the edge are formed complementary to one another, both the recess and the filling can be cut with one and the same laser cutting device. Due to the identical contour, there is also a time saving in the production of the valuable or security product, which is provided with a filling.

The present invention is explained in more detail below with reference to figures, the examples shown being merely exemplary and not representing any restriction with regard to the scope of the invention described. They show in detail:

1 shows a schematic isometric illustration of a value or security product in the form of an identity card;

Fig. 2 is a schematic sectional view of the identity card along the line I-I; and FIG. 3 shows a schematic representation of a layer or a single-layer base body with the recess and personalized filling shown above.

A valuable or security product 100 is shown in FIG. The value or security product 100 can be an identity document, such as a passport or a part thereof, an identity card, an access card or the like, a check card or a bank note or some other document. All of the following examples are described using such a card as representative of other document types. The value or security product 100 can also be a component of another value or security document, for example a passport.

In FIGS. 1 and 2, the value or security product 100 is shown in the form of an identity card, which has been joined together, for example, to form a base body in the form of a laminate of several inner layers, in particular polymer layers 140. For example, the polymer layers 140 can consist of PC and / or PET. The individual layers can be unfilled or filled with fillers. In the latter case they are opaque, otherwise transparent. The layers can preferably be connected to one another in such a way that they form a monolithic block which practically cannot be split.

In FIG. 2, the layers of a base body of the valuable or security product 100, which were still isolated prior to lamination, are shown visibly for illustration purposes only. The interfaces are no longer visible in the finished laminate. The outer layers 150 of the card can be formed as a final plastic protective film or consist of a protective varnish that has been applied to the card after lamination. The plastic protective film or protective varnish is transparent so that the information underneath is visible from the outside. In particular, however, one or more printed layers 140a, for example of a portrait picture 110, remain visible, which is or are preferably arranged immediately next to or behind the outer layer 150.

The valuable or security product 100 has an upper substrate surface 101 and a lower substrate surface 102. On the upper substrate surface 101 are the face or portrait image 110 of the holder of the card and four data fields, namely a first data field 120, a second data field 130 with card and owner data in plain text and a third data field 125 and a fourth data field 135 with the Card and holder information in Braille, such as Braille. The third data field gives the data of the first Data field 120 in Braille, and the fourth data field 135 specifies the data of the second data field 130 also in Braille. The data in the first and in the second data field 120, 130 are produced by printing layers which lie on an outer layer of the document, but directly below the outer protective layer 150.

The valuable or security product 100 shown in the figures has in the present case a recess 200 which is introduced into every layer of the base body. The layers each have a planar upper side 202 and a likewise planar underside 204 aligned parallel to this. The recess 200 thus forms a type of window, the “frame” of which is formed by an edge 206 connecting the upper side 202 to the lower side 204. As can be seen from the figures, the edge 206 is formed to run at least in sections inclined at an angle with respect to a normal of the upper side 202 and the lower side 204. Thus, the edge 206 cannot simply be realized with a punching tool, which is why a laser cutting device is used in the present case in order to create the recess 200 with regard to its shape and design; or in other words the recess 200 is based on a laser cut.

In order to provide the edge 206 with as many irregularities as possible and thereby increase the counterfeit security for the edge 206 and thus for the valuable or security product 100, the edge 206 of the recess 200 runs inclined at a first section by a first angle with respect to the normal of the Upper side 202 or the lower side 204, wherein the edge 206 of the recess 200 runs inclined at a second section by a second angle deviating from the first angle with respect to the normal of the upper side 202 or the lower side 204. In this way, two-dimensional and three-dimensional cuts can thus be realized through the shaping of the edge 206, which would not be possible with a simple window punch. It is also possible to provide the edge of the valuable or security product 100 with an obliquely lasered contour. It is also possible to form a diagonally slightly distorted card or a card edge personalized by notches or the like. By position The notches introduced can then be used to make references to the name or also to the document type of the valuable or security product 100, which also serves to protect against forgery.

In Figure 3, a valuable or security product 100 is shown comprising a single layer, the recess 200 being made in this layer. The edge of the card is also formed at an incline with respect to the normal of the upper side 202 and the lower side 204 or is even rounded, which improves the feel of the valuable or security product 100. In addition, the recess 200 is provided with a contour, which in the present case is adapted to personal information of the card holder, which in the present case relates purely by way of example to the year of birth, which is the year 1996 as an example. However, the contouring of the recess 200 also makes it possible to laser product-specific information.

The position shown is contrasted with a filling 208, which in the present case is formed in one piece. The filling 208 is preferably inserted into the recess 200 by means of a fast picker or a SCARA robot (English for “Selective Compliance Assembly Robot Arm”). However, it is possible to design the filling 208 in several parts. The filling 208 also has an overhead or upper surface 210 which is aligned parallel to a lower or lower lower surface 212. Both surfaces are planar. The surface 210 is connected to the lower surface 212 by means of a side cheek 214, which in the present case is completely adapted to the contour of the edge 206 of the recess 200. In other words, the side cheek 214 of the filling 208 is formed complementary to the shape of the edge 206 of the recess 200. Thus, the side cheek 214 also has, in sections, an inclination with respect to a normal to the surface 210 or the lower surface 212, since it is adapted to the shape of the edge 206 of the recess 200. An inclined side wall 214 of the filling 208 also makes it easier to insert the filling 208 into the recess 200. The filling 208 is also based on a laser cut. There is the possibility that the filling 208 has a coloring which differs from a color of the base body or the layer provided with the recess 200 in the present case. The coloring of the filling 208 itself can also be adapted to product-specific and / or person-specific information, which can preferably also be found on the card. For example, the year of birth (as shown) or corresponding letters of the name or a reference to the birthday of the user of the valuable or security product 100 can be used as personalization. It is also possible that the filling 208 is formed from a different material such as the layer or the base body of the valuable or security product 100, so that this different material configuration can also be perceived or felt.

The use of a corresponding laser cutting device for producing the recess 200, the card edge and the contour of the filling 208 results in significant efficiency gains compared to known methods which make such openings in the layers by means of a punching tool. In the present case, for example, there is no post-processing with regard to burr removal. In addition, additional two-dimensional and / or three-dimensional security features can be implemented in a simple manner, which would not be possible if a window punch were used.
