Description

State of the art

The invention is based on an insert sheet for a book-type identification document, a book-type identification document and a method for producing a book-type identification document according to the preamble of the independent claims.

Book-type identification documents generally consist of a plastic or cardboard or linen envelope and data pages of paper and / or plastic. The data pages are attached by a seam on the envelope or on the inside cover page. The data pages have a personal data page on which the most important personal data and the image of the holder of the identification document are arranged. Other data pages may contain further entries for the holder of the identification document or free areas for subsequent entries, for example visas. The data pages can be made of different materials and have a different thickness.

Under identification documents, for example, passports, book-like identity cards or driver's licenses, provisional personal documents or the like understood below.

From the publication EP 0 430 282 A2 Multi-layer identity cards are already known which contain intermediate layers of a thermoplastic elastomer, for example of thermoplastic polyurethane.

There is always the problem that data pages containing plastic, have no satisfactory bending properties. Repeated bending causes first cracks in the laminated sides and finally a break of the side, especially in the area of the seam or where different materials merge into one another. The broken data page is replaced in the worst case by the book-type identification document.

To solve this problem are in the document EP 0 917 966 B1 Insert sheets for book-like identification documents described, which consist of several layers, but at least partially not adhere to each other in the region of the interface.

EP 1 245 407 A2 FIG. 12 shows and describes a flexible and multilayer datasheet of a security document, for example, a passport having a laser-writable layer and a flexible backing layer bonded to the laser-writable layer via a lamination layer. The datasheet has an area where the seam for attaching the datasheet to the passport is placed. The carrier layer extends into this region while the laser-writable layer ends before it.

Advantages of the invention

The insert sheet according to the invention with the features of the independent claim has the advantage that all layers of the insert sheet are firmly connected to each other and thus have a high stability and security against counterfeiting. Furthermore, the insert sheet has very good bending properties and cracks in the document and thus breaks in the side, in particular in the area of the seam, are avoided. It is also possible to personalize such insert sheet as usual and einzulaser data in this data page. Such data may be image data, letters and numbers as well as codes, for example a barcode. Furthermore, it is possible to provide various security features such as tilting or holograms and other known from the ID-1 area security features in the insert sheet.

The basic idea of the invention is that, in an insert sheet for a book-type identification document, which is connectable to a seam in a hinge area along one side with the other book parts and consists of at least one layer of a thermoplastic elastomer and at least one further layer which at least to extend a layer of a thermoplastic elastomer into the hinge area and to let the at least one further layer extend only to the hinge area. According to the invention, it is provided due to the required strength that the layer thickness of the thermoplastic elastomer in the hinge region in the range between 400 .mu.m and 800 .mu.m, preferably between 500 .mu.m and 800 .mu.m.

For insert sheets to be equipped with microchip and contactless data transmission, it is provided according to the invention to embed the transponder coils in the layer of thermoplastic elastomer, because this material flows around the coil well, the coil is stored sprung in this layer, thereby avoiding damage to the coil become. The coil is embedded outside of the hinge area in the layer of thermoplastic elastomer.

Similar advantages can also be named for the book-type identification document according to the invention with the insert sheet according to the invention.

There is further provided an inventive method for producing a liner sheet for a book-like identification document having the features of the independent claim, which describes a simple and inexpensive method for producing such a liner sheet. It is particularly advantageous that all layers are connected by lamination and thus a high strength and high anti-counterfeiting security is achieved for the resulting from the process insert sheet, In addition, the embedding of a transponder coil in the layer of thermoplastic elastomer is a simple and inexpensive Herstellungsunasverfahren for Insert sheet specified by the damage, the transponder coil can be avoided.

The measures listed in the dependent claims advantageous refinements and improvements of the independent claims are possible objects.

To achieve a high stability, it is advantageous to provide the layer of the thermoplastic elastomer in the hinge region with a greater thickness than in the remaining regions. It is particularly advantageous to choose the thickness of the layer of the at least one thermoplastic elastomer in the hinge region such that the total thickness in the hinge region is equal to the total thickness in the remaining regions of the insert sheet. It is thus ensured a continuous transition between the hinge region and the other areas of the insert sheet and thus largely avoided voltage concentrations when bending in this area. It is also advantageous if at least one further layer is arranged on one side of the layer of the thermoplastic elastomer, to allow it to extend to different distances up to the hinge region. As a result, a trailing edge and an increased concentration of stress during bending at the point in the transition region between the hinge area and the other areas of the insert sheet are avoided during bending. It is particularly advantageous to offset the layers by at least 500 μm, particularly advantageously by at least 1 mm.

Particularly advantageous developments of the method according to the invention for the production of the insert sheet consist in each case of arranging two further layers above or below the layer of thermoplastic elastomer on the same side and stapling these layers together before lamination.

As a result, slipping of the layers during lamination is excluded. Stapling is understood to mean the selective welding or melting of the layers, wherein these welding points are preferably outside the range of the future data page. Thus, these welds are later cut off, for example when punching the data page and are no longer visible in the finished document. For example, two to four stapling points are set for a data page in the usual pass page format.

A further advantageous embodiment of the method according to the invention consists in that at least one further layer is arranged essentially on regions of the layer of thermoplastic elastomer which have a smaller thickness than reinforced regions of the layer of thermoplastic elastomer. This ensures that after the production of the insert sheet according to the invention in the hinge region, the layer of thermoplastic elastomer has a greater thickness than in the other areas of the insert sheet. If the upper layer is advantageously arranged, if at least two further layers are to be arranged on one side of the at least one layer of thermoplastic elastomer, then the upper layer is projected so that it protrudes somewhat beyond the reinforcement region, then it is ensured that after production At least two further layers of one side of the at least one layer of thermoplastic elastomer protrude differently far to the hinge region and an excessive stress concentration during bending stress and the formation of a tear-off edge are avoided. In the production of such a liner sheet, it is particularly advantageous and cost-effective to produce several benefits, for example two or four liner sheets, on a sheet together, wherein the liner sheets are punched out of the sheet after lamination. In this case, the areas in which the layers of the insert sheets were stapled are separated from the finished insert sheet in an advantageous manner.

FIG. 1 a shows an insert sheet 10 according to the invention for an identification document, for example a passport or identity card or the like. On the insert sheet 10 data of the holder of the identification document, for example, the name 12, the address 13 or a person-specific identification number 14, for example, an ICAO line arranged. Furthermore, the passport image 11 of the holder of the identification document is arranged on one side, here on the right side of such an insert sheet. The insert sheet has a hinge region 22, in which the course of the seam is indicated by means of dashed lines 20. With this seam, the insert sheet is connected to the remaining parts of the identification document. The hinge portion 22 is the portion of the insert sheet in which the insert sheet is bent after sewing with the remaining portions of the passport book. It extends about 5 mm, but at least 3 mm left and right of the seam.

Parallel to the seam, the insert sheet has side edges 24 and 25, wherein the side edge 25 is disposed on the opposite side of the seam. On the insert sheet 10 provided as a data sheet for a book-type identification document, further security features are arranged, which are shown here with reference to guilloches 15. Further, as security features, copy protection elements, micro-writing, luminescent pigments, holograms, watermarks and the like are usable.

In FIG. 1b a further embodiment of an insert sheet 10 according to the invention is shown, which is constructed on two sides. In the middle of the two data pages, the hinge region 22 is arranged, in which, after the completion of the identification document, the seam runs, which is indicated here by means of a dashed line 20. Such a two-sided insert sheet has two seams 25 and 25 'opposite the seam. The remaining components of such insert sheet, based on FIG. 1 a are explained in FIG. 1b have been omitted for clarity. A two-sided insert sheet after sewing into the ldentifikationsdokument four pages, ie two front and two backs, while based on FIG. 1 a one-sided insert sheet shown results in two sides (a front and a back).

An insert sheet generally consists of several layers of paper and / or plastic which, on the one hand, offer a high degree of protection against forgery and, on the other hand, provide protection for the personal data placed on the attachment sheet. Such insert sheet is also referred to as personalization page. The data entered in the personalization page can be given not only the name or the address as well as personal numbering but also the date of birth, the place of birth, a signature or other personal data. The data contained on the insert sheet may be printed and / or lasered. In the case of laser scanning, the data are written into the finished laminated sheet by means of a laser. The laser intensity is controlled so that discoloration takes place in the interior of the data sheet, ie in a paper or plastic layer, so that the data inscribed by means of laser become visible. External plastic layers are not damaged during this process and remain smooth. In a further embodiment, the laser power can also be adjusted so that the top layer of the insert sheet is changed during writing and a tactile microrelief is formed. Furthermore, in the upper layer of the insert sheet, an optically effective relief may be arranged which cooperates with the underlying printed or laser-induced inscription.

Based on FIG. 2 is a side view of a book-shaped, identification document according to the invention shown. Evident is the outer envelope or lid 30, which consists of paper and / or cardboard and / or plastic. Arranged in the envelope 30 is firstly the insert sheet 10 according to the invention and further book pages 32, wherein the insert sheet 10 and the further pages 32 are connected to the envelope 30 by means of a seam. The seam, not shown here, is arranged in the hinge region 22 of the insert sheet 10. In the illustrated embodiment for an inventive identification document, a one-sided insert sheet is arranged in front of the remaining data pages of the identification document. The insert sheet can also be arranged between the other data pages 32 of the book-type identification document. In a further embodiment, a two-sided insert sheet, as based on FIG. 1b shown used in an identification document according to the invention.

In FIG. 3 is an inventive insert sheet shown schematically in cross section. The insert sheet 10 consists of a middle layer of a thermoplastic elastomer 40 and one each above and below another arranged layer 42, 43. The other layers are made of high temperature resistant plastic. The cross section was taken along the basis of FIG. 1 a shown line AA. The upper and lower further layer 42, 43 extends in the direction of expansion of the insert sheet 50 from the side edge 25, which is opposite to the seam, to the hinge region 22. However, the two further layers do not protrude into the hinge region 22. Only the centrally arranged layer of thermoplastic elastomer 40 extends from the seam side opposite the edge 25 to the hinge area 22 to the side edge 24, which is located on the hinge portion 22.

As the thermoplastic elastomer, thermoplastic polyurethane (TPU) may preferably be used, but other thermoplastic elastomers may be used. For this purpose, the entire group of thermoplastic polyurethanes, the group of thermoplastic copolyesters and the group of thermoplastic polyether block amides are available. Polycarbonate (PC), polyethersulfone (PES), polyetheretherketone (PEEK), polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyoxymethylene (POM), polysulfone (PSU), for example, can be used as high temperature stable plastics. Polyetherimide (PEI) or polyamide (PA) can be applied. These high temperature stable Plastics can be used individually or in combination as further layers 42, 43.

Based on FIG. 4 and 5 are further embodiments of an inventive insert sheet based on sections of cross-sections along the line AA FIG. 1 a shown. FIG. 4 1 shows a layer of thermoplastic elastomer 140 arranged centrally in the insert sheet body and the further layers 144 and 142 and 145 and 143. The hinge layer 22 has the layer of thermoplastic elastomer 140 thickened such that the insert sheet 10 in the hinge region 22 same thickness along the direction 51 perpendicular to the sheet plane 50 as in the other areas of the insert sheet. The respective further layers 142 and 144 as well as 143 and 145 arranged on the same side of the layer of thermoplastic elastomer 140 extend up to the hinge region 22 and extend as far as this region. The further layers, which are arranged on one side of the layer of the thermoplastic elastomer, thus end at one and the same edge. The design that the insert sheet in the hinge area and in the other areas has the same thickness, ensures greater security against counterfeiting and increased strength of the insert sheet in the hinge area 22nd

In the basis of FIG. 5 a shown embodiment, which in turn shows a central arrangement of the layer of thermoplastic elastomer 240 and on each side two more overlying further layers 242 and 244 and 245 and 243, extend the other layers disposed on one side of the layer of thermoplastic elastomer The two further layers 242 and 244 as well as 243 and 245 arranged on one side of the layer of thermoplastic elastomer do not therefore have a common end edge. This is advantageous to avoid that the stress is concentrated too much at a common edge in a bending stress.

The distance d of two parallel edges 242a and 244a of the associated further layers 242 and 244 or the distance d of the parallel edges 245a and 243a of the associated further layers 245 and 243 is greater than 500 μm, preferably greater than 1 mm. The two parallel edges 242a and 244a of this embodiment are also based on FIG. 5b shown in a view from above. Analogous to FIG. 1 In the hinge region 22, the seam 20 is arranged after the completion of the identification document. This will be in FIG. 5b indicated by a dashed line. Furthermore, the edges 242a of the upper further layer 242 are indicated by a solid line and 244a of the underlying further layer by a dotted line. The edges 242a and 244a are parallel to each other and parallel to the side 24 of the insert sheet 10 which is closest to the seam.

In FIG. 5c a further embodiment for the course of the edges of the further layers is given, wherein the edges and the seam area analogous to FIG. 5b Marked are. The edges 242a 'and 244a' in this case are not parallel to each other and also not parallel to the side of the insert sheet, but have a shape comparable to the legs of an isosceles triangle, with the apex located approximately in the middle of the side 24. In this case, the layers 242 and 244 lying on one side of the layer of thermoplastic elastomer are formed with edges 242a 'and 244a' in the shape of the legs of an isosceles triangle with opposite opening angles, so that lying in the outer lying away from the apex lying areas the upper layer continues to project towards the hinge area and, in the area around the vertex, the lower layer projects further towards the hinge area. This embodiment, in addition to the distribution of stresses in bending an additional security feature when this edge design is about visually recognizable.

The same additional advantage offers an embodiment, which is based on FIG. 5d is shown. Here, the edges 242a "and 244a" are formed substantially parallel to one another and to the side 24 of the insert sheet. However, they are designed with a wavy shape. Other forms, such. B. Zackenformen are also conceivable. The mean distance d 'denotes the distance that the center lines have the same values as those based on FIG. 5 a explained distances d have.

In the layer of thermoplastic elastomer, a transponder coil is embedded, which is used for non-contact transmission of data for a microchip arranged in the insert sheet and is electrically connected thereto. The transponder coil is embedded in a region outside the hinge region in the layer of thermoplastic elastomer.

In further embodiments of the invention, several layers of thermoplastic elastomer may be provided within a liner sheet according to the invention. The layers of thermoplastic elastomer are separated in this case by intermediate layers. Furthermore, more than two further layers may be provided on each side of the thermoplastic elastomer.

According to the invention, the at least one layer of the thermoplastic elastomer in the hinge region has a layer thickness between 400 .mu.m and 800 .mu.m , preferably between 500 .mu.m and 800 .mu.m . Other layers of high-temperature stable plastic, layer thicknesses of between 20 μ m and 500 μ m, preferably between 100 μ m and 500 μ m, most preferably between 300 μ m and having 500 μ m. In the remaining area of the insert sheet, not belongs to the hinge region, the thickness of the at least one layer of thermoplastic elastomer is between 20 .mu.m and 300 .mu.m , preferably between 50 .mu.m and 200 .mu.m . The thickness is the extent of the layers along the direction 51 perpendicular to the sheet plane 50 of the insert sheet according to the invention.

Based on FIGS. 6, 7 and 8th The process according to the invention for producing an insert sheet for a book-type identification document will now be described below. The FIGS. 6 and 7 show first the production of the layer of thermoplastic elastomer, which has a greater thickness in the hinge area than in the other areas. The basis of the FIGS. 6, 7 and 8th illustrated process steps are again shown schematically in cross section. Furthermore, the method is based on a single-sided insert sheet, which is produced as a double benefit. It can be used analogously for two-sided inserts or single or multiple benefits.

Based on FIG. 6 It is shown that further layers of thermoplastic elastomer 340 'and 340 "are disposed above and below a layer of thermoplastic elastomer 340. These further layers of thermoplastic elastomer 340' and 340" are arranged in the region later in the hinge region a reinforcement should arise. FIG. 6b shows the direct arrangement of the three layers of thermoplastic elastomer 340, 340 'and 340 "on top of each other, for better fixation these layers can be stapled together.

In FIG. 7 is a further embodiment of a layer of thermoplastic elastomer 340 shown schematically in cross section. In this embodiment, the layer of thermoplastic elastomer 340 was manufactured as a molded part by extrusion.

As already explained above, a transponder coil, which allows non-contact data transmission, is embedded in a layer of thermoplastic elastomer. Such a coil can be applied, for example by means of printing, spraying or by other application methods, to a layer of thermoplastic elastomer. In a further process step, a further layer of thermoplastic elastomer is laminated so that both layers of thermoplastic elastomer with interposed transponder coil embedded the layer of thermoplastic elastomer 340, as in FIG. 7 shown form.

The further process steps for the production of the insert sheet according to the invention are now based on FIG. 8 be explained. First, the further layers 242, 244, 245 and 243 for the first use and the further layers 242 ', 244', 245 'and 243' for further use in the desired order, as in FIG. 8 a shown superimposed. In a preferred embodiment, the further layers 242 and 244 and 245 and 243 as well as 242 'and 244' as well as 245 'and 243' located on one side of the layer of thermoplastic elastomer are then stapled one over the other so that slipping of the respective layers against each other is prevented becomes. This is based on FIG. 8b shown. In this case, the further layer 242, 242 ', 243 and 243' which in each case lies outside in the future insert sheet projects slightly beyond the respective other layer on the side where the hinge area is to join in the future. In the following, based on FIG. 8c As shown, the layer of thermoplastic elastomer is interposed between the further layers such that the further layers extend where the layer of thermoplastic elastomer 340 has a smaller thickness. In the central reinforcing region, which in the future is intended to be the hinge region of the insert sheet of the thermoplastic elastomer according to the invention, the further layers 242, 244, 245, 243, 242 ', 244', 245 'and 243' are not arranged. Only the protruding piece of the respective outer further layers rests on the area of the reinforced layer of thermoplastic elastomer. In a preferred embodiment, the layers arranged on top of each other can be stapled first.

In the following, all layers are laminated. As a result of the intractable fusion of the layers with one another, the initially projecting end of the respectively outer layers 242, 243 and 242 'and 243' is also connected to the remaining layers in such a way that a smooth surface is formed in these regions. The laminated semi-finished product for the insert sheet according to the invention is based on FIG. 8d shown.

Subsequently, in a further process step, the areas provided for the insert sheet according to the invention are determined from the basis of FIG FIG. 8d punched out semifinished product or the two benefits separated in a different way. In the embodiment shown here in the joint processing of two benefits of each one-sided insert sheets arise, as in FIG. 8e shown, two Einzeinutzen, each having only one layer of thermoplastic elastomer 240 and 240 'in a hinge region 22.

For producing an identification document according to the invention, the insert sheet together with the other data pages and the envelope is now assembled in such a way that all pages have the correct sequence. The insert sheet is placed such that the hinge area is in the area of the future seam. After fixing the document components they are sewn together. The seam then runs in the hinge region of the insert sheet, ie in the region which has only the thermoplastic elastomer. It can then be connected to other process steps to the production of the identification document. To the On the one hand, the data pages and the envelope can still be cut to their required dimensions. Furthermore, a protective layer, for example made of plastic or linen, which may have additional printing on the envelope can still be glued. Furthermore, a fold line is provided along the seam, so that the book is also folded at the predetermined location. In a one-sided embodiment of the insert sheet is the hinge portion 22, as in FIG. 2 shown, on the one hand something beyond the kink or seam area addition.
