Description

201231308 VI. Description of the Invention: [Technical Field] The present invention relates to a security and/or value document having an electroluminescent arrangement as a novel security element in which hidden information is illuminated by illumination The illuminating device can be selectively used as a visible additional security feature, as well as a method of its manufacture. [Prior Art] In order to take a step ahead of possible counterfeiting, in the market for security and/or value documents, especially ID documents, it is necessary to continuously improve the security functions used and develop new security functions. The configuration of security features should make forgery technically difficult and can be easily identified by pure vision. Plastic safety and/or value documents, especially identification documents (such as ID cards), are preferably manufactured without the use of an adhesive layer as a multilayer composite for lamination at elevated temperatures and pressures. ) to avoid the separation of the subsequent layer structure instead of the recognition function. Corresponding safety functions are introduced into these multilayer composites before or during the lamination process and must therefore be configured to withstand the lamination parameters without being destroyed. In addition, there is no need to introduce weak points into the safety function of the multilayer composite, which again allows subsequent non-destructive opening of the composite. The safety functions in θ safety and/or value documents are usually divided into three types: 201231308 Full level: - Level 1 safety functions are purely visual and do not require the use of additional aids. - Level 2 safety features require accessibility tools (such as lenses, optical filters, reading devices) to be visible. - Level 3 security functions can only be identified in the laboratory by means of a forensic method. Through analysis, this usually includes at least partially corrupted files. Although Level 1 security features can be detected very quickly, the disadvantage is that good enough forgery can be established with limited funding. It takes a very high cost to falsify Level 3 security features, but it is often impossible to avoid at least partially damaging the identification of security files. The present invention is directed to improving Level 2 security functions. Techniques for applying electroluminescent (EL) devices (also known as EL lights, EL lamps) to various substrates have existed for decades. Cold light sheets are usually printed on plastic sheets or glass substrates. The special function of the plastic sheet at the forefront as a substrate qEL device (also called cold light sheet) for flexible applications is that the entire light emitting surface has Consistent luminous intensity, low power consumption and virtually no heat generation. An AC current source must be used to supply power. It has been stated in the literature that EL devices printed on plastic substrates are used in many very different applications, but there is no description of the method of directly using such devices to introduce safety functions into safe and/or value documents, or 4 201231308 Hidden information in women's and/or value documents is directly visible. The problem of attack is especially the lamination of the EL device. Preferably, the adhesive free laminati (m methc) d is used to make the ampoules and/or enamel files to avoid subsequent opening of the documents in the adhesive layer. Therefore, the lamination is carried out at a high pressure and a high temperature to form a (four) layer having a wide surface, preferably a single one composite. It is no longer possible to generate non-destructive dismantling identity documents in this way. These documents are fused at a surface pressure of from 1 Torr to 4 Torr and a temperature of approximately 190X:. The lamination process can take up to 2 minutes or even longer (depending on the number of laminates). In order to have a security function, an EL device incorporating a security and/or value document must withstand such a layering process without damaging its function. In an example of an EL device having a transparent electrode (tranSparent eiectr〇de) based on indium tin oxide (ITO), the plastic sheet is also sputtered or evaporated in a vacuum. The way of coating) covers the wide surface with ITO. The ITO layer thus forms a weak point, and then the security and/or value documents can be opened by the weak point, so such an EL device is not suitable as a security element in security and/or value documents. Furthermore, a disadvantage of the wide surface IT0 electrode in safety and/or value documents (especially ID cards) is that if the document is maintained at the edge during application to the current source, then when applying the file to an alternating current source The user can receive a corresponding electric shock. 201231308 [Summary content] Therefore, the present invention provides a security and/or value document having an EL device as a secure element and optionally having hidden information, which can be hidden by integrating the el device into a secure and/or value document. Become visible. Therefore, it is necessary to find an EL device for plastic-based safety and/or value documents that is not destroyed under lamination conditions, and to maintain functionality, and the EL device does not have any weakness of the security technology.

Α : When the illuminating rainbow device is installed, the naked eye does not detect/detect the existence of the tribute. The hidden information can be used as an additional security element by the value document or the value document. ^ Queen and / EL devices in security and / or value documents provide several possibilities ^ improve the fake money of this article. In other words, an EL split that is not visible from outside the security and value documents can be used as a security function 2 only when the EL device is illuminated. In addition, the information that is visible to the f (same as the floating field water with the light passing through) can be integrated into the security and/or structure in a hidden manner. Furthermore, the el device having the (4) line symbol 6 201231308 f can represent the transparent area in the file when the device is not redundant, and when the device is lit, it will be clear by the transparent light guide property. Illuminated. Therefore, it is also possible to emit light when a transparent light transmitting EL device is produced in a security and/or value document. Tian*·, 占儿月 provides a security and/or shell member comprising a multi-layer structure, characterized in that the multilayer structure comprises an electroluminescent device having at least a transparent electrode layer, the transparent electrode and a conductive polymer . ^ 3 main 乂 The electroluminescent device is placed between semi-transparent (10). The translucent layers may be independent of each other as a translucent plastic layer or a translucent ink layer. Preferably, at least one of the translucent layers is a translucent plastic layer, and both of the stomachs are preferably translucent layers. The beta layer special car ~ When the E LI is not lit, the naked eye can not perceive the bow | into the anal device of the price file of the present invention, so the authenticity inspection requires the sub-current source of the sub-sampling as an aid, transmission or material Illuminated foot = voltage. The event of the EL device is subsequently completely or partially destroyed by the event of opening the multilayer composition for the purpose of counterfeiting. There is no EL device at all, or all or part of the function is destroyed, and the pseudo-k product (including the previous opening) can be clearly identified. Externally visible contacts can be closed as redundant (dUmmy), and the device behind it does not actually function. The surface covered by the electroluminescent device contains only a partial table Φ of the safety and/or value document. The surface of the electroluminescence (4) is particularly preferably an edge region which does not include safety and (5) has an element. 201231308 The present invention is a safe and/or valuable document, preferably an ID card, such as 丄v敉佳, a body injury 5 and a clear bank card, a credit card, a security card, a passport, a driver's license, preferably in the present invention.

The EL device can be in direct contact with the semi-transparent layer (preferably the plastic layer) provided by the security and/or value-for-money library of the present invention. . In the case of the purely sturdy hood, the EL device can be in direct contact with the semipermeable plastic layer provided in two of the safety and/or value documents of the present invention. m @ In a preferred embodiment of the invention, at least one other plastic layer (preferably at least a transparent plastic layer) may be disposed on the EL device and the security and/or 3 file + at least - optionally provided translucent layer (preferably (Four layers) In other preferred embodiments of the present invention, in the security and/or value document of the present invention, one of the transparent plastic layers may be disposed on the side of the EL device having the transparent electrode layer, and the image information may be set. The plastic layer, 8 201231308 and the optionally provided translucent layer (preferably the plastic layer) are on the same side as the el device. In the embodiment of the present invention, although the EL device and the image information are disposed between different plastic layers, they are disposed in areas above each other in terms of area. Since in this preferred embodiment the 'hidden information in the form of image information is set between the transparent and the selectively provided translucent layer (preferably the plastic layer)', when the light is not lit, the naked eye cannot penetrate the package. The hidden information is seen for the two translucent layers of the el device (i.e., the non-transparent layer, preferably the plastic layer). Without this information or by damaging the EL function of the EL device (which makes it impossible to see the information or only see some of the information), the counterfeit can be clearly identified. The above and other objects, features and advantages of the present invention will become more <RTIgt; Import image information into security and/or value documents. This can be by printing methods (such as screen, inkjet, offset or laser printing, etc.), engraving methods (such as laser engraving), or coating.

In a preferred embodiment of the invention, the EL device selectively providing a translucent layer (preferably a plastic layer) has recesses filled with at least one plastic layer. By means of the illumination EL device, it is possible to particularly clearly illuminate a groove which may have a printed or symbol shape. Therefore, the embodiment of the present invention can further introduce the security element into the security and/or value document. When the EL device is illuminated, the area of the groove is particularly bright due to the light-guiding property of the transparent plastic layer. These grooves are considered to be clear transparent areas of the document when the EL device is not illuminated. When the EL device is not illuminated, this will be able to identify the cloudiness of these regions and thus reduce its transparency in the event of forging a security document by opening a multi-layer composite. When the EL device is lit, forgery can be identified by uniformly illuminating the defects in the grooves. The complete absence of an EL device would also be a sign of a forged document. The selectively provided translucent layer (preferably a plastic layer) and the security and/or value document of the present invention are preferably independent of each other, and at least one translucent layer (preferably a plastic layer) is white, black, colored or It is filled with filler.

In a preferred embodiment of the invention, the multilayer structure may comprise at least one further plastic layer (which includes a laser-sensitive additive)&apos; which are not disposed between the selectively provided translucent layers. For example, the so-called laser marking additive can be envisaged as a laser-sensitive additive, that is, one of the absorbers in the wavelength range of the laser used is preferably erbium-doped. Aluminum garnet (neodymium-doped yttrium aluminum garnet,

Nd:YAG) is in the wavelength range of the laser. Such laser marking additives and their use in moulding compounds are described in WO-A 2004/50766 and WO-A 2004/50767, available from DSM under the commercial brand Micabs.

To this end, a sheet of transparent plastic layer for creating a translucent and/or grooved at the corresponding contact point of the EL device is facilitated prior to lamination, e.g., by pressing an electrical connection that allows the laminated electrode. An alternating current source is used in this example to provide power (typically having a voltage of at least 15 volts) to excite the EL layer to illuminate. The frequency of the alternating current is also important because the higher frequencies produce a stronger picture of the EL light 42 201231308 Bright power. The voltage commonly used for EL light is an AC voltage having a frequency of 110 volts at 400 Hz. The AC voltage is preferably generated by a DC/AC inverter. When the AC voltage is used for the two electrodes of the EL element, the EL lamp will be illuminated. Power supply can be generated using one or more batteries, one or more rechargeable accumulators, or by using an external current source. Nowadays, current semiconductor technology can even produce miniature frequency converters that can be laminated into documents and can be used to non-contactly illuminate EL lamps by using the energy required for induced transfer of copper coils laminated therein. . This type of power supply will not be able to see from the outside whether the EL unit is laminated. Generally, the voltage required to operate the EL lamp is transmitted as a direct current by a battery or a button battery. The inverter can be used to convert DC power to AC with the desired voltage and frequency. The electrical connection of the EL device for the corresponding device (reader), in which the file can be set, can be fed to the outside of the security and/or value document by means of contact points in this example. In other configurations of the security and/or value document of the present invention, the resulting EL element can be driven by using an induction coil and an inverter connected to the EL device prior to the lamination step. The EL device can have one or more wire tracks for driving the device. The so-called bus bar can be used as a wire track for driving the EL device. The wire track can be used before, after or between the electrode layers (1) and (4), and the wire track is preferably used for one working step, particularly preferably for use with the joint. The wire guide can be used in the form of a silver bus bar, preferably produced from a silver paste and/or silver paint product. It is also possible to use a graphite layer before using the silver busbar. The electrical terminals can be produced, for example, by using a conductive paste which can be burned into a combination and mixtures or alloys comprising tin, zinc, silver, and other suitable conductive metals or ruthenium. Conductive straps are typically used for conductive and at least partially transparent thin coatings using a doctor blade, roller by screen printing, brushing, ink jet printers, or dispensing applications or comparable application methods known to those skilled in the art. The layers are then heat treated, usually in an oven. The selectively provided translucent plastic layer or transparent plastic layer is preferably used as a substrate for the EL device. The second semi-transparent layer (preferably a plastic layer) or the transparent plastic layer optionally provided is preferably used as a protective layer for the EL device. The EL device used in the security and/or value document of the present invention has high security for subsequent disassembly of security and/or value documents since all components (including electrodes) of the EL device are selectively printable ( For example, by screen printing). With this technique, the EL device can be printed on the desired location of the security and/or value document, although the edge regions of the document are still uncoated. During subsequent lamination of the security and/or value documents, the EL device is thus soldered to the compressed plastic casing, which may be selectively monolithic depending on the choice of plastic and may no longer be non-destructively disassembled. Further, the EL device used in the present invention is easily resistant to lamination parameters, and surprisingly, the security and/or value document of the present invention can be personalized by laser engraving without damaging the EL device. Since the thermal peaks in the laser region partially split the EL device is expected, the personalization by laser engraving after 44 201231308 is surprising.

Example 1 a) The EL apparatus (EL-A of Fig. 4) was layer-printed by flat screen printing to the polycarbonate of Makrofol® ID 6-2 having a thickness of 200 μm from Bayer MaterialScience. Base sheet (layer A in Figure 4) 48 201231308 - Transparent electrode layer (1) (front electrode) - Light-emitting layer (2) - Dielectric layer (3) - Other identical transparent electrode layer (4) (back electrode ) and subsequent - contacts and wire tracks (5) - white pigment translucent layer (6). The total thickness of the printed EL device is about 75 μm. Therefore, the total thickness of the polycarbonate sheet printed with the EL device at the printing position is about 275 μm. The following printing formulations (printing pastes) are hard for individual layers.

Next, a circle having a diameter of 6 mm, a 201231308 groove, is printed corresponding to the electrical contacts from the a) printed sheet of the EL device to the printed sheet of the C layer, and is disposed on the side from the a) plate on which the device is printed. c) Printing a transparent polycarbonate sheet (D layer of Fig. 4) from Bayer MaterialScience's 200 μm thickness of Makr〇f〇l® DP1230 6-2 to a side with individual graphics by a laser printer side. The size and position of the pattern are adjusted to the size and position of the EL device on the sheet obtained in a), and are disposed on the side of the side of the sheet from a) where the EL device is not printed, so that the EL device is located from The other side of the sheet is placed and the individual graphics are placed on top of each other in the stack of sheets. d) White translucent polycarbonate sheet from Bayer MaterialScience's Makr〇f〇lnD 4-4 (〇1〇2〇7) with a thickness of 1〇0μηη by offset printing with decorative graphics (No. The B layer of Fig. 4 is printed to the side 'and is disposed on the side of the sheet from c) with the unprinted side of the individual pattern printed on it. The individual patterns printed to the sheet from c) are no longer visible 'and thus represent hidden information. e) Transparent laser engraved polycarbonate sheets (F layer 4 of Figure 4) from Maker Material Technology's MakrofbHD 6_2 (75GG61) with thickness ι〇〇μηη set on the printed side of the sheet from d) . f) After p, the thin plate stack including the sheets from a) to e) will be laminated in this manner. Lamination was carried out by pressure and heat according to the following lamination parameters: the laminator was heated to 190 degrees, the foil stack was placed therein and the pressure was 15 NW for 8 minutes, and the pressure was then increased to Ν/cm for 2 minutes. Then the cooling phase begins. When 52 201231308 reaches 38 degrees, turn on the machine and remove the laminate. g) The laminate of 仗g) is printed in ID1 format (card of 85. h) The card is then engraved on the C and F layers formed by the sheets of e) using a Nd:YAG laser. Next, a voltage of 11 volts and 4 Hz was applied at the contact point to test the function of the card. When the EL device is illuminated, individual patterns printed on the sheet from c) that were previously invisible to the naked eye are visible. Therefore, the function of the EL device is not destroyed or damaged by laser engraving in h). Since the dense layer in the edge region is composed of the individual layers a) to e) obtained by lamination, the function of the EL device must be broken to open the laminated card. Next, the bending strength of the card was tested according to ISO 7810. A curved crack in the surface of the card was observed after about 70 〇〇〇 bending. Therefore, the card has a bending strength comparable to a card made of, for example, polycarbonate without an integrated EL device. Even if there is a crack transmission exceeding 5% of the width of the card, the function of the EL device can be maintained. The card can last for 100 hours of heat storage at a temperature of 80 degrees and a relative humidity of 85% without the need to modify the card. The power of the £1 device is maintained unharmed. Example 2 a) As described in a) of Example 1, the EL device was applied to a white translucent polycarbonate sheet from Makrofol 8 Π 4 4 (010207) having a thickness of ΙΟΟμπι from Bayer 53 201231308 Materials Technology, Inc. The difference in a) of Example 1 is shown in Table 6 below for the printing formulation for the translucent layer (6): Substance----Ί Capacity/wt.% Desmophen® 670 (BMS) 17.3 Additol® XL480 1.0 (butoxygen) 50 wt·%) Desmodur® N75 MPA (BMS) 17.4 Ethoxypropyl acetate 4.3 methoxyacetic acid 0 Ti〇2 60.0 The total thickness of the printed EL device is about 75 μm. Therefore, the total thickness of the polycarbonate sheet on which the EL device is printed at the printing position is about 175 μm. Next, the groove is removed from the sheet in which the EL device is printed in the EL agricultural area using the star-shaped punching. b) A transparent laser-engraved polycarbonate sheet from Bayer MaterialScience's Makrofol® ID 6-2 (750061) with a thickness of ΙΟΟμπ! is printed on one side by offset printing with decorative graphics. Next, a circular groove having a diameter of 6 mm was printed on the printing sheet of the C layer corresponding to the electrical contact from the a) printed sheet of the el device, and was disposed on the side from the a) sheet on which the EL device was printed. 54 201231308 C) A transparent polycarbonate sheet from Bayer MaterialScience's vtakrofol® ID 6-2 with a thickness of 400 μm is printed on one side by offset printing with decorative graphics and placed on the back of the EL device. One side of the sheet from a). d) A transparent laser-engraved polycarbonate sheet from Bayer MaterialScience's Makrofol® ID 6-2 (750061) having a thickness of (7) was placed on a sheet having a thickness of 400 μm from c). Next, the thin plate stack containing the sheets from a) to d) obtained in this method is laminated under the conditions of 'f in the example 1', as shown in g) and h) Excluded and engraved by Nd:YAG laser. During the lamination, the star grooves are filled with the transparent material from the sheets of the layers 1 and c). The finished card contains a transparent area of the star. Next, the function of the card was tested again by applying a voltage of 110 volts and 400 Hz at the contact point. When the EL device is lit, the star-shaped transparent area is illuminated by the light guiding function of the transparent material. The function of the EL device is not destroyed or damaged by laser engraving in h). Since the dense layer in the edge region is composed of the individual layers a) to d) obtained by lamination, the function of the EL device must be broken to open the laminated card. After opening, the star-shaped transparent area cannot be assembled without leaving a visible cloud layer. Comparative Example For comparison, a transparent electrode containing poly(3,4-vinyl) was replaced and used as a conductive polymer with an IT-based transparent dielectric 55 201231308. After laminating any of the sample cards produced, the EL device is no longer functional. This example shows that not only the present invention (an example of a safety and/or value document), an EL device incorporating an identity card can withstand lamination processing parameters without being damaged, so that it can be used as a security function when illuminated, and can be made by an EL device. Hidden information becomes visible, which can be used as an additional security feature. In addition, it is surprising that the function of the EL device is not destroyed or damaged by the information introduced by subsequent laser engraving.
