Description

“INSERT SHEET FOR AN ELECTRONIC IDENTIFICATION DOCUMENT SIMILAR TO A BOOK” TECHNICAL FIELD

[0001] The present disclosure relates, in general, to an insert sheet configured to be used in an electronic identification document similar to a book, in particular, to an insert sheet comprising an integrated articulation section. In addition, the present disclosure relates to a method for making an insert sheet of the type identified above.

BACKGROUND

[0002] In general, security articles, such as security documents and identification documents, must be continuously improved, particularly their security must ensure that counterfeiters cannot produce counterfeit security articles based on security articles authentic. Examples of identification documents that have more than one insertion sheet or page include, but are not limited to, passports, driver's licenses, national identity cards, border crossing cards, security clearance badges, security cards, visas, immigration documentation and cards, firearm licenses, membership cards, phone cards, stored value cards, employee badges, debit cards, credit cards and gift certificates and gift cards.

[0003] However, since security articles of the type mentioned above include more than one page, connecting the plurality of pages of such an electronic identification document can also be problematic. In such a case, it is a type of booklet, for example, a page of passport data as part of a multi-page passport. A passport data page normally comprises two sections. A data page section and the articulation section that protrudes from the data page section.

[0004] For example, document No. WO 2017/032827 A1 shows an identification document similar to a book that includes several sheets or insertion pages. In the present context, the identification document comprises a front book cover and a book back cover and one or more pages of data confined therein. A revealed personalization data page may comprise at least two outer layers of plastic material, which have been bonded together. The plastic material can be polycarbonate. An additional inner layer can be provided, for example, made from paper. This inner layer contains personalization data and a photo as well as machine readable OCR data. In addition, a transponder module can be provided between the two inner layers. This multilayer data page can be sewn into an articulation section. However, due to the multi-layer hinge section, its flexibility can be problematic.

[0005] Another embedded sheet for a book-like identification document is known from document No. EP 1 663 667 Bl. The known embedded sheet for a book-like identification document has an articulated area, which can be joined to other parts of the book with a seam along one side in the hinged area. It comprises at least one layer of a thermoplastic elastomer and at least one additional layer. At least one additional layer extends towards the plane of the embedded sheet essentially opposite the hinged area to the hinged area. At least one layer of a thermoplastic elastomer extends into the hinged area. A transponder coil is incorporated outside the hinged area in at least one of at least one layer of thermoplastic elastomer.

[0006] Document No. U.S. 2014/0265295 A1 refers to an article that includes a biodata page. The page can define a perimeter that includes a border and an articulated layer attached to at least a portion of the biological data page. The hinged layer may comprise a cross-linked polyurethane. In some examples, the hinge layer may include a cross-linked thermoset polyurethane.

[0007] Document No. U.S. 2012/0164419 A1 shows a sheet that can be laser-marked with multiple layers for an electronic passport that includes three sheets. A first sheet includes a transparent polycarbonate resin composition that includes a thermoplastic polycarbonate resin and a laser light energy absorbing agent. A second multilayer sheet includes a transparent thermoplastic resin including a thermoplastic polycarbonate resin. At least one layer between the outer layers and the core layer of the second multilayer sheet includes at least one selected from a dye and a pigment. A third sheet can include laminated sheet. The sheet that can be laser marked with multiple layers for an electronic passport can have excellent laser marking capability and high contrast.

[0008] Document No. U.S. 2008/0169638 A1 refers to a personal document in the form of a book, which comprises a book cover, a personalized multilayered side containing personalized data, and internal pages. The personalized side and the inside pages are fixed with a seam to the book cover. The personalized multi-layer side is provided with a central area that is produced from a textile layer that is joined on both sides to a thermoplastic layer as a bonding agent that covers the central area to the projecting edge, forming an articulated area . The bonding agent can have a reactive resin or a mixture of partially reactive resin that permanently joins the textile layer and the plastic layers that cover the central layer produced from, for example, a mesh. An RFID element comprising an IC element is integrated into the central area for the contactless transfer of biometric data from the owner of the personal document. The custom side is sewn by means of a seam in the region of the projecting edge.

[0009] Document No. WO 2015/027971 A1 refers to a data sheet for insertion, preferably, in a security document similar to a book and / or of value. The data sheet consists of at least two stacked stacks of an organic polymer material, in which a layer of paper material is arranged at least in a sub-area between the layers and outside the layers, forming a flap as a joint. The layer of paper material is coated and / or imbued on one side or on both sides at least partially with an organic binder, at least in the area between the layers of organic polymer material, and is bonded to the two layers through the binder.

[0010] The company “gemalto” offers a data page portfolio including data pages with different thicknesses produced, for example, from polycarbonate. The data page can provide a highly flexible link for user convenience and fused data page joints for document robustness.

[0011] The present disclosure refers, at least partially, to the improvement or overcoming of one or more aspects of previous systems.

SUMMARY OF THE REVELATION

[0012] According to one aspect of the present disclosure, an embedded sheet configured for use in a book-like identification document comprises a first hinged layer consisting of polycarbonate and a second hinged layer consisting of a flexible material other than polycarbonate, for example, PET, polyurethane, cloth, mesh. The second hinged layer is attached to the first hinged layer. A first data page layer that forms a part of a data page and a second data page layer that forms an opposite part of the data page are attached to the first hinged layer and the second hinged layer, respectively, so that the first and second hinged layers are positioned between the first and second data page layers to form a data page section. The data page section has a data page thickness and the first and second data page layers form an internal front edge of the data page. The first and second hinged layers extend beyond the inner front edge of the data page so that a hinge section is formed that has a hinge thickness less than the data page thickness.

[0013] According to an exemplary embodiment of the present disclosure, the layers of pure polycarbonate data page, on either side of the articulated layers, are produced, by themselves, from several layers of different types of polycarbonate in a sequence suitable to achieve various desired properties, such as printing, laser engraving, transparency, opacity, incorporation of devices and enabling security features. For example, a data page layer that comprises a clear, laser-capable overlay over a clear, laser-capable printed layer with a white core layer underneath can be used on one side of the hinged layer. The other layer of data page, that is, the other side of the hinged layer, may be a white printed core layer with a clear overlay.

[0014] Examples of different types of polycarbonate that are typically used as layers of data page on a passport data page are white, clear, capable of clear, double laser, or superlaser-marking.

[0015] According to another aspect of the present disclosure, a method for making an embedded sheet may comprise the step of providing a first hinged layer consisting of polycarbonate and providing a second hinged layer consisting of a flexible material other than polycarbonate, for example example, PET, polyurethane, cloth, mesh. In addition, the method can comprise the steps of providing a first layer of data page that forms a part of a data page section and providing a second layer of data page that forms another part or opposite part of a page section of data. By connecting the first and second hinged layers and the first and second data page layers to each other so that the first and second hinged layers are positioned between the first and second data page layers and the first and the second hinged layers extending beyond an internal front edge of data page, a hinge section is formed which has less hinge section thickness than a data page thickness section.

[0016] The typical temperatures of the polycarbonate lamination process are, for example, 160 ºC to 200 ºC. Parameters, such as pressure and time, can vary considerably depending on the specific product and laminator.

[0017] Other resources and aspects of the present disclosure will be evident from the description and attached drawings below.

DETAILED DESCRIPTION

[0027] The following is a detailed description of exemplary modalities of the present disclosure. The exemplary modalities described in this document are designed to teach the principles of the present disclosure, enabling people of ordinary skill in the art to deploy and use the present disclosure in many different environments and for many different applications. Therefore, the exemplary modalities are not intended to be, and should not be considered as, a limiting description of the scope of protection. Preferably, the scope of protection should be defined by the attached claims.

[0028] The present disclosure is based at least in part on the realization that, currently, all the articulated layers of the multilayer articulation section extend throughout and through the data page section, and consequently it is a full layer that runs through the data page section. The hinge section is provided as a multilayered structure that can provide durability and structural flexibility in the hinge and provides, for example, an outer support layer on one side, both sides or as an inner support layer on the joint. By adding a flexible hinge layer to the hinged polycarbonate layer, the hinge section can retain the advantages of polycarbonate, such as suitability for printing, laser engraving and lamination stability, while also absorbing the properties of the flexible hinge layer , such as flexibility, tear resistance, durability, crack prevention and resistivity.

[0029] According to an exemplary embodiment of an embedded sheet, at least the first and second hinged layers can form a front edge closed by a polycarbonate strip. The polycarbonate strip can be formed during lamination or by a similar process of the multilayer joint composition. In particular, the open edge should preferably be closed to prevent any moisture from entering the multilayer structure.

[0030] According to another exemplary embodiment of the present disclosure, the individual layers can be bonded together or by lamination, welding, adhesives or another process well known in the art.

[0031] In accordance with another exemplary embodiment of the present disclosure, at least one of the first and second layers of data page may include a defined surface pattern formed, for example, by a plurality of empty spaces and / or cavities. Consequently, empty spaces and / or cavities can be introduced into the polycarbonate layers. Then, with the use of a flexible articulated material such as thermoplastic polyurethane (TPU) which is more viscous than polycarbonate during lamination, the material flows and fills the voids or cavities in the polycarbonate. This can have multiple benefits such as increased adhesion to polycarbonate and increased flexibility of the multilayer joint. In addition, continuous patterns such as text, maps, symbols or other outlined formats and / or with empty spaces or cavities in both the projecting articulation section and the data page section can act as a safety feature visually revealing the proof adulteration.

[0032] Another exemplary embodiment of an embedded sheet is such that the polycarbonate content in the flexible hinge section can be varied depending on the requirements of the product. Additional hinge section treatments allow for a much higher polycarbonate content in the hinge section with additional benefits.

[0033] Typical compositions that can work without any additional treatments can be provided by an inner hinged layer produced from a material other than polycarbonate with an inner hinge layer thickness of 240 to 250 µm maximum and a hinged layer of flexible polycarbonate with a layer thickness of 30 µm of polycarbonate on both sides. Alternatively, a hinged inner layer produced from a material other than polycarbonate with a maximum hinge inner layer thickness of 250 µm can be provided with a flexible hinged polycarbonate layer with a 50 µm polycarbonate layer thickness in one side only. Consequently, a multi-layer hinge section with a nominal thickness of less than 300 µm after lamination is created. In general, the overall thickness of the multilayer joint after lamination can be kept to a minimum to minimize the impact of the joint on opening and closing, for example, in a passport booklet.

[0034] The insertion sheet can be structured so that the total thickness of the data page is less than 600 µm and / or so that the articulation thickness is less than 300 µm. Alternatively or additionally, the respective thickness of the data page of the first and second layers of data page can be less than 300 µm and / or the respective thickness of the hinged layer of the first and the third hinged layers is less than 100 µm, particularly , less than 40 um.

[0035] According to the present disclosure, an articulated multilayer layer, as disclosed, also provides part of the functionality and benefits of the data page normally provided by the material in the data page section itself, for example, opacity, reflection of laser, laser engraving, security printing, clear window. Various grades of polycarbonate can be used for layers of data page, such as laser-capable, super-laser-capable, clear or white, all of which offer different visual and performance benefits. This contributes to obtaining all the functionality expected from a passport data page in a thinner construction with fewer layers.

[0036] In addition, in accordance with another exemplary embodiment of an embedded sheet, in accordance with the present disclosure, at least parts of an RFID electronic product may be provided in an inner edge or outer hinged layer or layer of data page in the data page section of the embedded sheet revealed therein.

FIRST EXEMPLIFICATIVE MODE

[0037] Referring now to the drawings, the Figure | shows a schematic cross-section of a first exemplary embodiment of an embedded sheet 5 according to the present disclosure. In the present context, the embedded sheet 5 can comprise a first hinge layer 21 and a second hinge layer 22. The first hinge layer 21 can be produced from polycarbonate. The second hinged layer 22 connected to the first hinged layer 21 may consist of a flexible material other than polycarbonate. Such material may comprise, for example, PET, polyurethane, cloth or mesh or a combination of these materials.

[0038] The first data page layer 11 and the second data page layer 12 adjoin the first and second hinged layers 21, 22. The first data page layer 11 and the second data page layer 12 can be produced from any suitable materials known in the art, for example polycarbonate.

[0039] The two outer layers of data page 11, 12 form a front edge 24. The hinged layers 21, 22 extend beyond the front edge 24 and form a hinge section 20. Those parts of the hinged layers 21, 22 that do not extend beyond the front edge 24 may be part of a data page section 10 of the embedded sheet 5.

[0040] As can be seen in Figure 1, the data page section 10 has a thickness tdp greater than the th thickness of the hinge section 20. The hinge section 20 has a th thickness of the hinge formed by the thickness of the two layers articulated thl1l and thl2. Consequently, the flexibility of the hinge section can be increased, but the flexibility and durability of the hinge section can be improved.

SECOND EXEMPLIFICATIVE MODE

[0041] Referring now to Figure 2, a second exemplary embodiment of an insertion sheet according to the present disclosure is described. Figure 2 shows a schematic cross-sectional view of an embedded sheet 5 corresponding to the insertion sheet shown in Figure 1, but comprising three hinged layers 21, 22, 28 instead of two hinged layers 21, 22. In the present context, the embedded sheet 5 may comprise a first hinge layer 21, a second hinge layer 22 and a third hinge layer 23. The second hinge layer or inner hinge layer 22 may consist of polycarbonate. Both the first and third hinged layers 21, 23 connected to the first hinged layer 21 can consist of a flexible material other than polycarbonate, for example, PET, polyurethane, cloth or mesh. A first data page layer 11 and a second data page layer 12 abut the first, second and third hinged layers 21, 22, 23 and are connected to the first and third layers 21, 23, respectively. As for the first embodiment, the first data page layer 11 and the second data page layer 12 can be produced from polycarbonate.

[0042] Again, the two outer layers of data page 11,12 form a common front edge 24. The hinged layers 21, 22 extend beyond the common front edge 24 and form a hinge section

20. Those parts of the hinged layers 21, 22 that do not extend beyond the front edge 24 may be part of a data page section 10 of the inlaid sheet 5.

[0043] In the present context, as can be seen in the schematic sectional view of the insertion sheet 5 shown in Figure 2, the data page section 10 has a tdp thickness greater than the th thickness of the hinge section 20. The layers external hinges 21, 23 can have a layer thickness thl1, thl3, both of which are less than the thickness of layer thl2 of the hinged inner layer 22. Consequently, the flexibility of the hinge section can be increased, but the flexibility and durability of articulation section can be improved.

THIRD EXEMPLIFICATIVE MODE

[0044] Referring now to Figure 3, a third exemplary embodiment of an insertion sheet according to the present disclosure is described. Figure 3 shows a similar schematic sectional view of an embedded sheet 5 as in Figure 2, but the materials of the three articulated layers 21, 22, 23 are different from the modalities of Figure 2. In the present context, the embedded sheet 5 can comprise a first hinged layer 21, a second hinged layer 22 'and a third hinged layer 23. The second hinged layer or inner hinged layer 22' can be produced from a flexible material other than polycarbonate, for example PET, polyurethane, cloth or mesh. Both the first and third hinged layers 221, 23 connected to the first hinged layer 21 may consist of polycarbonate. Again, the first data page layer 11 and the second data page layer 12 abut the first, second and third hinged layers 21, 22, 23 and are connected to the first and third layers 21, 23, respectively. As in the first and second embodiments, the first data page layer 11 and the second data page layer 12 can be made from polycarbonate or can comprise the same.

[0045] Again, the two outer layers of data page 11,12 form a common front edge 24. The hinged layers 21, 22 ', 23' extend beyond the common front edge 24 and form a hinge section 20. These portions of the hinged layers 21, 22, 23 'that do not extend beyond the front edge 24 may be part of a data page section 10 of the embedded sheet 5. The data page section 10 has a tdp thickness greater than the thickness th of the hinge section 20. The outer hinged layers 21º, 23 'can have a layer thickness thl1, thi3, both of which are less than the thl2 layer thickness of the hinged inner layer 22'. Consequently, the flexibility of the hinge section can be increased, but the flexibility and durability of the hinge section can be improved.

THIRD MODIFIED EXEMPLIFICATIVE MODE

[0046] Referring now to Figure 4a, a third modified exemplary embodiment and an insertion sheet according to the present disclosure are described. Figure 4a shows a similar schematic cross-sectional view of an embedded sheet 5 as in Figure 3, however a polycarbonate strip 50 is provided which seals the front edge of the hinge section 20. The strip 50 can be attached to the front edge.

[0047] Alternatively, strip 50 can be formed during the lamination process of layers 21 ', 23', as shown in Figure 4b at 50 °. In the present context, the hinged layers 21, 23 * produced from polycarbonate are pressed or compressed together during lamination to seal in the material of the inner hinged layer 22 ', for example, polyurethane.

FOURTH EXEMPLIFICATIVE MODALITY

[0048] Referring now to Figure 5, a fourth exemplary embodiment of an insertion sheet 5 according to the present disclosure is described. Figure 5 shows a similar schematic cross-sectional view of an embedded sheet 5 as in Figure 3, however patterns that comprise voids and / or cavities 26, 27 are provided in the hinge section on the outer hinged layers 21 'and 23' inside of the polycarbonate material. Of course, a strip of polycarbonate 50, 50 'as shown in Figure 4a and 4b can also be provided in the embodiment of Figure

5.

FOURTH MODIFIED EXEMPLIFICATIVE MODALITY

[0049] Referring now to Figure 6, a fourth modified exemplary embodiment of an insert sheet 5 in accordance with the present disclosure is described. Figure 6 shows a similar schematic cross-sectional view of an embedded sheet 5 as in Figure 5, however the patterns comprising voids and / or cavities 26, 27 are provided not only in the hinge section 20, but extend into the data page

10. Of course, a polycarbonate strip 50, 50 'as shown in Figure 4a and 4b can also be provided in the embodiment of Figure 6.

FIFTH EXEMPLIFICATIVE MODE

[0050] Referring now to Figure 7, a fifth exemplary embodiment of an insert sheet 5 in accordance with the present disclosure is described. Figure 7 shows a similar schematic cross-sectional view of an embedded sheet 5 as in Figure 3, but at least parts 40, 41 of an RFID are incorporated at least in the inner pivot layer 22 'in the area that is part of the page section of data 20. Of course, a polycarbonate strip 50, 50 'as shown in Figure 4a and 4b can also be provided in the embodiment of Figure 7.

[0051] Finally, Figure 8 shows an electronic document 100 comprising a cover 101, 102 which abuts a plurality of insertion sheets 5. All insertion sheets 5 are sewn at 103 within the hinged area 20 on cover 101, 102 forming a booklet. It should be noted that the insert sheets 5 may not comprise a data page section and a hinge section 20 only, but an insert sheet 5 may be formed so that the hinged layers 21, 22 or 21 ', 22 ° , 23 'can extend so that two data page sections 10 are formed with a common hinge section 20 between the two data page sections 10 provided on opposite sides of the hinge section 20 (viewed in a sectional view ).

[0052] According to an exemplary embodiment of the present disclosure, a method for making an embedded sheet may comprise the steps of providing a first hinged layer 21; 21º consisting of polycarbonate and providing a second articulated layer 22; 22 'consisting of a flexible material other than polycarbonate, for example, PET, polyurethane, cloth, mesh. In addition, a first data page layer 11 and a second data page layer 12 are provided. In addition, the first and second hinged layers 21, 22; 21,22 'and the first and second data page layers 10, 11 are linked together so that the first and second hinged layers 21, 22; 21 ', 22' are positioned between the first and second layers of data page 11,12 and the first and second articulated layers 21, 22; 21 ', 22' extend beyond an internal front edge of data page 24. As already mentioned, typical temperatures of the polycarbonate lamination process are, for example, 160 ° C to 200 ° C. The parameters, such as pressure and time, can vary considerably depending on the specific producer and the rolling mill. Consequently, a pivot section 20 is formed which has a pivot section thickness th less than a tdp data page thickness section.

[0053] It will be noted that the previous description provides examples of the revealed systems and methods. However, it is contemplated that other deployments of the disclosure may have different details from the examples cited. All references to the disclosure or examples of the disclosure must refer to the particular example then discussed and should not imply any limitation on the disclosure in general.
