Description

[Technical field]

[0001] The present invention relates to a method for producing a laminate and a laminate inlay, to a laminate, a laminate inlay and to a security document, in particular in the form of a bank card, an identity card, a data page of a document, a credit card or a bank note, comprising such a laminate. [Background technology]

[0002] It is known to produce security documents, in particular bank cards, credit cards etc., from a number of laminate sheets which are melted and / or glued together in a lamination process to form a laminate. These security documents usually have a larger lateral extent to the lamination direction of the individual films which are laminated to one another than to said lamination direction. Here, these security documents usually have a standardized format size and thickness (for example the size and thickness of a card) and security elements, such as electronic chips, embossments or overprints, are embedded in or attached to the laminate. Such security documents are characterized in that, due to the lamination process, successive plies, for example plastic films, have a particularly good adhesion to one another and are therefore particularly anti-counterfeiting and resistant to external environmental influences.

[0003] Such a security element is disclosed, for example, in EP 2 886 357 B1. This security element comprises a number of laminate sheets which are fused in a lamination process to form a monolithic block. Furthermore, a varnish layer is printed on the laminate sheets before carrying out the lamination process. The laminate sheets are then laminated in a lamination process such that the varnish layer is placed inside between the two laminate sheets, resulting in a security feature, which cannot be forged without destroying the laminate because it is laminated between the laminate sheets and is particularly well protected against environmental influences. Summary of the Invention [Problem to be solved by the invention]

[0004] It is an object of the present invention to define an improved laminate, an improved laminate inlay for producing the laminate, and a method for producing the laminate. [Means for solving the problem]

[0005] The above object is achieved by a method for manufacturing a laminate or laminate inlay, comprising the steps of: The method includes the steps of providing a first laminate film, in particular made of polycarbonate, having a first side and an opposite second side; providing at least one transfer film, the at least one transfer film having a carrier film and a decorative ply, the decorative ply being peelable from the carrier film, the at least one transfer film having a first side facing the opposite side of the carrier film and a second side facing the carrier film; printing a radiation curable adhesive on the first side of the first laminate film and / or on the first side of the decorative ply of the at least one transfer film, such that in one or more first regions, the radiation curable adhesive is applied to the first side of the first laminate film and / or the decorative ply to form a radiation curable adhesive layer, and in one or more second regions, the radiation curable adhesive is not applied to the first side of the first laminate film and / or the decorative ply. 1. A method comprising the steps of: printing; applying at least one transfer film to a first surface of a first laminate film, wherein at least one partial region of one or more first regions having a radiation-curable adhesive layer and at least one partial region of one or more second regions not having a radiation-curable adhesive layer are positioned between the first surface of the decorative ply and the first surface of the first laminate film; at least partially curing the radiation-curable adhesive layer; and peeling the at least one transfer film from the first laminate film, wherein in one or more first partial regions overlapping with the at least one first region in at least a predetermined area, the decorative ply is separated from the carrier film upon peeling and remains on the first laminate film, and in one or more second partial regions, the decorative ply remains on the carrier film and is peeled off together with the carrier film.

[0006] Further post-curing of the adhesive layer takes place on the basis of an aftertreatment, for example by further irradiation, or, for example in the case of cationic systems, by an independent further curing reaction over time.

[0007] To manufacture the laminate, a plurality of continuous films having one or more first partial regions with a first laminate film and a decorative ply and a laminate inlay including at least one second laminate film are laminated to form the laminate.

[0008] Furthermore, the object is achieved in particular by a laminate inlay produced by the method, which comprises a first laminate film having a first and an opposite second side, in particular made of polycarbonate, at least one decorative ply peeled from the carrier film of at least one transfer film and a radiation-curable adhesive layer at least partially cured and arranged between the decorative ply and the first side of the first laminate film, in one or more first partial regions, in which the at least one decorative ply is not provided in one or more second partial regions, which are peeled off together with the carrier film.

[0009] Furthermore, the object is achieved in particular by a laminate formed by the method, which comprises a plurality of continuous films laminated to one another to form the laminate, the plurality of continuous films including a first laminating film, in particular made of polycarbonate, and at least one second laminating film, the first laminating film having a first side and an opposite second side, at least one decorative ply peeled from the carrier film of at least one transfer film and a radiation-curable adhesive layer at least partially cured and arranged between the decorative ply and the first side of the first laminating film, in one or more first partial regions, the at least one decorative ply being absent in one or more second partial regions and peeled off together with the carrier film.

[0010] Furthermore, this object is achieved by a security document comprising such a laminate and a laminate inlay for producing the laminate or the security document.

[0011] The invention is based on the knowledge that an individually structured decorative layer, which is protected by the radiation-curable adhesive layer from breaking and / or degradation in the subsequent lamination process, is formed on the laminate film by the overprinting and transfer process of the radiation-curable adhesive layer in predetermined areas. In the present case, the radiation-curable adhesive layer therefore has a "dual function". On the other hand, this adhesive layer serves to apply in a structured and individual manner to the laminate film decorative layers which cannot be applied, or which are insufficiently applied, or which cannot be applied with the required layer thickness or resolution, in particular by printing and / or thermal stamping methods. Moreover, it has surprisingly been found that the radiation-curable adhesive layer further stabilizes these decorative layers applied during the lamination process, preventing in particular a deterioration of the optical effect of the decorative layers. This stabilization is achieved in that the areas of the transferred decorative layer are provided with "stabilizing structures" which are highly stable against the effects of heat and pressure when the radiation-curable adhesive cures and during the crosslinking reactions of said processing, are provided in precisely registered fashion, protect the decorative layer in a precisely registered manner from the effects of heat and pressure during the lamination process, and also provide a corresponding uniform load per unit area on the decorative layer, thereby allowing the use of decorative layers which, without said stabilization, are themselves very thin, mechanically unstable and / or sensitive to temperature influences.

[0012] The decorative ply can therefore be designed in such a way that a high resolution is achieved during transfer, due to the thin and fragile layer thickness which allows it to be peeled off from the carrier film in very small areas, and correspondingly the decorative layer or layers which are at least partially present are also transferred with a high resolution.

[0013] Moreover, there is no need to use heat or pressure to initiate crosslinking reaction and structure the decorative layer. Therefore, the thermal and pressure loads of the decorative layer and the laminating film can be kept very low during the transfer process. By providing the transferred decorative layer with a stabilizing structure in exact registration and by providing the second partial area, a corresponding "bonding bridge" is further provided. This maintains the advantages of using lamination methods and allows a stable layer bond to be achieved when the laminate inlay according to the invention is used.

[0014] Advantageous embodiments of the invention are defined in the dependent claims.

[0015] Laminate film and laminate inlay refer to a single or multi-layer film that is laminated with one or more further layers, in particular a laminate film, to form a laminate, in particular a monolithic laminate, by lamination. The film is preferably formed by a single or multi-layer plastic film that comprises a thermoplastic on one side, at least in certain areas, thus making it possible to "weld" said side to the further laminate film by lamination, at least in certain areas. Preferably, the film has one or more layers. The layers consist of a thermoplastic material, in particular polycarbonate, PVC or PET, which preferably form the main component of the film.

[0016] Furthermore, further layers may be used that are already bonded at low temperatures or are capable of bonding materials such as polyesters or polycarbonates that do not have good adhesion to each other during lamination, for example, thermoplastic polyurethanes or reactive adhesive layers.

[0017] Lamination methods refer to methods that use heat and pressure to bond two or more layers together. One or more layers melt at the layer boundaries at least in predefined areas and are fused together at least in predefined areas. In lamination methods, films are preferably heated to a temperature above 120°C and simultaneously pressed together by pressure. The temperature required during lamination depends on the materials used, for example PVC is much lower than polycarbonate. When bonding different materials together, an additional layer, for example thermoplastic polyurethane, acts as an adhesive layer.

[0018] By laminate is meant a layered body having a composite of two or more film layers bonded together by a lamination process, in particular bonded, e.g. fused (fused) and / or glued, to a monolithic block by a lamination process.

[0019] During the lamination step, the first partial area or areas containing the decorative ply are preferably arranged inside between the first lamination film and at least one second lamination film. The second partial area or areas without the decorative ply on the first lamination film ensure that in these areas other materials, in particular transfer plies, do not interfere with the bonding of the first and second lamination films during the lamination step and therefore a good interlayer adhesion is achieved between the first and second lamination films when the lamination is carried out. This is especially the case when the first and second lamination films are made of the same material, in particular PVC or polycarbonate.

[0020] The manufacturing and lamination method of the laminate inlay can be a roll-to-roll machining process, a roll-to-sheet machining process or a sheet-based machining process.

[0021] It is further advantageous if registration (alignment) is used, which results in precisely registered printing of the radiation curable adhesive onto the first laminate film and / or the at least one transfer film, precisely registered application of the transfer film to the first laminate film when the lamination process is performed, and / or precisely registered application of at least one second laminate film to the laminate inlay.

[0022] Registration or alignment or registration accuracy means the positional accuracy of two or more elements and / or layers relative to one another. Registration accuracy is within a given tolerance range that should be as small as possible. The registration accuracy of several elements and / or layers relative to one another is important to increase the reliability of the process. Positionally accurate positioning can be achieved in particular by sensory, preferably optically detectable registration or alignment marks. The registration or alignment marks indicate a particular individual element or area or layer or the registration or alignment marks themselves or are part of the element or area or layer to be positioned.

[0023] In the present specification, registration or alignment means that one or more method steps are performed in registration or in accurate registration with respect to structures in the first and / or second laminating film and / or one or more transfer films. By performing registration or alignment, the generated first or second partial areas are therefore registered, accurately registered, precisely aligned and positioned with respect to said structures and thus positioned in a predefined position with respect to each other. When registration or alignment is performed, registration marks are preferably detected on the transfer film or transfer films and / or the first laminating film and / or the second laminating film. These registration marks consist, for example, of overprints and / or perforations (perforations). The positional arrangement of the structures is determined by detecting these registration marks. However, the structures are also detected directly, for example, by a camera and corresponding image processing software. The structures may also be optically diffractive features, which are advantageously present together with optically diffractive registration marks. Depending on this, the printing of the radiation-curable adhesive, the application of one or more transfer films to the first laminating film and / or the application of the first laminating film or the laminate inlay to the second laminating film are furthermore controlled or regulated in such a way that the desired structures are precisely positioned relative to one another. For this purpose, it is advantageous, for example, based on the detected registration marks, to correspondingly adjust the position of the film web, for example by stretching the transfer film and / or the first laminating film and / or the second laminating film and / or by correspondingly changing the distance and / or by tracking the printing tool, for example in the case of flexographic printing, by adapting the speed of the printing cylinder for decoration and / or by synchronized activation of the digital printing, for example in the case of inkjet printing. As a result, the desired positional state is achieved and the structures are precisely positioned relative to one another.

[0024] Preferably, during the lamination step at least one second laminating film is applied to the first laminating film such that in the first surface region the one or more first partial regions with the decorative ply and the radiation-curable adhesive layer are provided between the first side of the first laminating film and the first side of the at least one second laminating film facing the first laminating film. Furthermore, it is advantageous for the first side of the first laminating film and the first side of the second laminating film to be in contact in the second surface region.

[0025] Thus, a first surface area is formed by the full surface area of ​​one or more first partial areas with the decorative ply provided between the first and second laminate films, and a second surface area is formed by the full surface area of ​​one or more second partial areas without the decorative ply provided between the first and second laminate films.

[0026] Then, during the lamination step, the first side of the first laminate film and the first side of the second laminate film are preferably melted and / or glued together in the second surface area, thereby achieving a reliable surface bond of the first and second laminate films during the lamination step and correspondingly protecting the decorative ply in the stack.

[0027] In this embodiment, the radiation-curable adhesive layer is preferably cured prior to the lamination step such that the radiation-curable adhesive layer is substantially dimensionally stable under the conditions of the lamination process carried out during the lamination step.

[0028] For example, unlike amorphous thermoplastics such as polycarbonate, amorphous (non-crystalline) PET or PVC, radiation curable adhesives retain sufficient mechanical stability at normal lamination temperatures that, although it may decrease slightly as the temperature increases, remains much higher than the softened surrounding lamination materials.

[0029] Preferably, the deformation of the radiation curable adhesive layer is determined by detecting the shape of the adhesive layer before and after the lamination process is performed and determining the average percentage of deviation from the starting shape after the lamination process is performed.

[0030] Furthermore, it is advantageous if during the lamination step the deformation of the decorative ply in at least one first surface region due to the radiation-curable adhesive layer is reduced by more than 50%, in particular by more than 80%, The deformation of the decorative ply is determined similarly to the deformation of the radiation-curable adhesive layer and compared with the deformation of the decorative ply with the radiation-curable adhesive layer and without the radiation-curable adhesive layer.

[0031] Tests have shown that such a radiation curable adhesive layer design can significantly prevent optical degradation of the decorative ply, thus significantly improving the optical quality of the laminate or security document.

[0032] In security documents, in particular the area ratio of the first surface area to the sum of the first and second surface areas is less than 80%, in particular 2% to 80%, more preferably 5% to 50%. Tests have shown that with these area ratios, on the one hand the interlayer adhesion between the first and second laminating films is sufficient to prevent counterfeiting even after lamination, and on the other hand the optical design possibilities are not limited.

[0033] Furthermore, tests have shown that the interlayer adhesion between the first and second laminating films after lamination not only depends on the area ratio of the first surface area to the second surface area, but also on the design of the first and second partial areas, and it has been found to be particularly advantageous if the first partial area or areas have a width of 8 mm or less, in particular a width of 5 mm or less.

[0034] It is furthermore advantageous if the minimum gap between the first partial regions is greater than 1 mm. 2It is even more advantageous for the laminate to have a thickness of less than 80% of a reference size of 100 mm. Tests have shown that one or more of the above properties significantly prevent point delamination or delamination of the laminate upon attempts to pull the laminate apart.

[0035] A further advantage of multiple first partial regions having relatively small areas spaced apart from one another is that the likelihood of tears and / or curling and / or buckling due to material flow of the laminate film during the lamination step to form the laminate is reduced.

[0036] The width of an area, sub-area or surface area means the shortest distance between the two opposite edges of the respective area. The length means the longest distance between the two opposite edges of the respective area.

[0037] Furthermore, it has proven to be advantageous if the first partial region or regions and / or the second partial region or regions have a width of 0.1 mm or more, in particular a width of 0.2 mm or more, as tests have shown that this ensures that the forces acting during the lamination step do not cause corresponding partial regions of the decorative ply to be displaced relative to one another and therefore the graphic design via the decorative ply is not deteriorated by the forces acting during the lamination step.

[0038] Furthermore, it has proven to be advantageous if the first partial region or regions and / or the second partial region or regions have a width of 0.1 mm to 0.6 mm, preferably 0.1 mm to 0.4 mm. By corresponding design of the first and / or second partial regions, the "rasterization" of the surface area of ​​the laminate into the first and second partial regions can be optically hidden and thus a continuously appearing graphic design with a larger area can be formed on the laminate.

[0039] It has further proved to be advantageous if the first partial region or regions and / or the second partial region form raster elements of a raster. The raster elements may each have any desired shape and may be designed differently, for example having a single shape such as round, rectangular, diamond, glyph, etc. The lateral extent of the raster elements, i.e. the width and length of the raster elements, is preferably selected to be between 0.1 mm and 0.6 mm. However, larger raster elements may also be used. Preferably, the raster elements are arranged in a regular one- or two-dimensional arrangement in the raster. However, the arrangement of the individual raster elements may not be constant but may vary, in particular randomly or pseudo-randomly according to a fractal pattern. Preferably, the raster has more than 10 raster elements, more preferably more than 20 raster elements.

[0040] Such a design of the first and second part regions results in a particularly good interlayer adhesion between the first and second laminating films, whereby the first and second part regions follow one another in a corresponding manner, thus preventing loss of interlayer adhesion even over large areas, and furthermore allows the production of large-area graphic representations without compromising the interlayer adhesion in the laminate.

[0041] Preferably, one or more second partial regions are provided which are defined by the outer edge of the laminate, preferably by all the outer edges of the laminate. Such an arrangement allows for a particularly high interlayer adhesion in the edge regions of the laminate, further improving resistance to environmental influences and protection against counterfeiting. Preferably, these second partial regions have a width of more than 2 mm, preferably more than 4 mm.

[0042] Furthermore, it has been found to be beneficial to select the area ratio of the first surface area to the surface area such that the adhesion, and therefore the peel force (separation force) required to peel the first laminate film from the second laminate film, is greater than 3.5 N. This is preferably measured at a peel angle of 90°, a peel speed of 300 mm / min and a strip width of 10 mm. Suitable measurement methods are described, for example, in ISO / IEC 10373-1. Here, the minimum peel force measured is preferably determined over a peel distance of at least 20 mm. The first and last 5 mm of the distance are not taken into account, nor are drops or other variations in the peel force over a distance of less than 1 mm taken into account.

[0043] Preferably, the peel angle is obtained by using a corresponding roller, preferably a roller with a diameter of 10 mm.

[0044] To ensure the shaping of the first and second partial regions in the laminate, during the manufacture of the laminate film, corresponding patterns of the first and second partial regions are formed in the first laminate film, and the corresponding sections of the first laminate film are laminated with the second laminate film to form the laminate.

[0045] Radiation curable adhesives are adhesives that cure by a polymerization or crosslinking reaction induced, at least in part, by radiation from a radiation source, to form long chain molecules. Such adhesives include, for example, reactive acrylates, epoxies or enol ethers and photoinitiators. During exposure to light, the photoinitiators form radicals or reactive cations (super acids), which induce the polymerization or crosslinking reaction of the long chain molecules. Depending on the radiation curable adhesive, different wavelengths of radiation are required for the crosslinking reaction to occur.

[0046] The radiation curable adhesive may also have multiple different photoinitiators that respond differently at different wavelengths or ranges of wavelengths, allowing the cure of the radiation curable adhesive to be staged in a targeted manner, providing the advantages described below.

[0047] In the printing step, a radiation-curable adhesive is printed, which preferably has a higher softening temperature than the first and / or second laminating film after the curing step has been carried out, in particular a softening temperature at least 10 K, preferably at least 20 K higher than the first and / or second laminating film, so that when the lamination is carried out, the radiation-curable adhesive layer is much more dimensionally stable than the first or second laminating film and therefore provides a particularly good mechanical protection for the decorative ply during the lamination process.

[0048] Radiation curable hybrid systems that cure after various further chemical reactions, such as thermal reactions, may also be used.

[0049] This allows in particular the flexibility of the adhesive layer to be adapted to the requirements: on the one hand, it is dimensionally stable enough to avoid degradation of the transfer ply during the lamination step to form the laminate, and on the other hand it is flexible enough to avoid breaks or cracks in the transfer ply, which would occur in the case of a very brittle and inflexible layer.

[0050] Preferably, the radiation curable adhesive printing is at 0.2 g / m 2 ~20g / m 2 , preferably 0.5 g / m 2 ~10g / m 2 , and more preferably 0.5 g / m 2 ~5g / m 2 The application weight is preferably 10% to 90% of the total thickness (100%) of the applied radiation-curable adhesive. Furthermore, the desired layer thickness is achieved so that the first laminating film and the transfer film are printed in register. The layer thickness of the radiation-curable adhesive in the first laminating film or the transfer film preferably has a value between 10% and 90% of the total thickness (100%) of the applied radiation-curable adhesive. For example, 10% of the radiation-curable adhesive may be applied to the transfer film and the remaining 90% to the first laminating film, or vice versa.

[0051] Tests have shown that when such application weights are used, the radiation-curable adhesive layer has sufficient mechanical stability to protect the decorative ply when performing the lamination process, while not significantly reducing the sharpness of the edges where the transfer of the decorative ply takes place.

[0052] Preferably, the printing of the radiation-curable adhesive is carried out by flexographic, screen, gravure or inkjet printing. Tests have shown that the use of flexographic printing results in a high edge sharpness in the area of ​​the transferred decorative ply. A particularly cost-effective and fast printing speed is achieved, in particular by using continuous roll-to-roll methods. The advantage of printing by inkjet printing is in particular that it achieves an individualization of the adhesive overprint and thus a corresponding individualization of the decoration produced by the transferred decorative ply.

[0053] Depending on the printing method, different viscosity ranges may be advantageous: for example, low viscosity is desired for gravure printing, medium viscosity for flexographic printing, and higher viscosity for screen printing.

[0054] Preferably, the radiation curable adhesive has a dynamic viscosity, in particular during printing by flexography, of 400 mPas to 2000 mPas, preferably 500 mPas to 1200 mPas, more preferably 500 mPas to 800 mPas. Tests have shown that by setting a corresponding viscosity a particularly good printing quality is achieved in terms of overprint resolution and sufficient area coverage of the printed area for subsequent transfer. Preferably, the viscosity is measured according to DIN ISO 3219:1994-10 ("Plastics - Polymers / resins in the liquid state or as emulsions or - Determination of viscosity using a rotational viscometer with defined shear rate", publication date October 1994), e.g. using a HAAKE Viscotester® VT550 (Thermo Fisher Scientific, Waltham, Massachusetts, USA), more preferably using the DIN adapter and measuring cup NV of a cylinder measuring device NV [NV] according to DIN 53019.

[0055] The adhesive components are, for example, monoacrylates, diacrylates, triacrylates, oligomers and monomers. The adhesive is cured, for example, using a conventional mercury lamp. The amount of UV light required varies depending on the adhesive system. Usually, it is 50 mJ / cm. 2A UV dose of 1000 nm or more is required. The UV mercury lamp may also be an iron or gallium doped emitter. IR input, which would result in undesired heating of the first laminate film and / or the transfer film, is advantageously reduced by a filter or a cold light reflector. Furthermore, a UV-LED emitter may be used as the irradiation source. The maximum intensity of the irradiation is preferably in the wavelength range of 330 nm to 410 nm. Furthermore, a flashing emitter, which emits light at high intensity for a short time, may be used as the irradiation source. The emitter may be used in a segmented form. During the process, the radiation is not irradiated over the entire width of the web, but mainly in the areas where the radiation-curable adhesive is printed. Such segmentation may be performed, for example, by a mask or, in the case of a UV-LED emitter, by switching on and off selected segments. The first laminate film and / or the transfer film are protected against harmful radiation during the process.

[0056] The radiation-curable adhesive layer is at least partially cured by irradiation with one or more irradiation sources. Curing may be performed in one curing step or in multiple curing steps, as described below. Irradiation is preferably performed with light in the wavelength range below 500 nm, in particular with ultraviolet light. In particular, the use of the wavelength range of 250 nm and / or 310 nm and / or 365 nm and / or 395 nm and / or 420 nm has been found to be effective for curing the radiation-curable adhesive layer. If mercury lamps or high-power UV-LEDs are commercially available in this region, typical power peaks are found in this region. Photoinitiators customary in the industry are also designed for these wavelength regions.

[0057] It is further advantageous if the first laminating film and / or the at least one transfer film has a transparency of more than 10% for at least one wavelength range of radiation, in which at least one photoinitiator is highly sensitive, so that sufficient curing can be achieved and no degradation of the laminating film and / or the decorative ply occurs due to the affected energy input.

[0058] The particular emission spectrum used for curing must be taken into account. For example, when using a UV-LED emitter with a peak wavelength of 365 nm and a half-width of 30 nm, transparency in this range, especially from 355 nm to 395 nm in this example, is important. The corresponding material selection preferably provides a transmission of more than 10% over this wavelength range.

[0059] Preferably, the radiation curable adhesive is cured in one curing step after or during printing of the radiation curable adhesive on the first side of the first laminate film and / or the decorative layer and prior to application of the at least one transfer film to the first side of the first laminate film. Such pre-curing can prevent or limit "flow" of the adhesive overprint on the first side of the laminate film and / or the decorative ply, thus providing a sharper contour of the overprint.

[0060] The dynamic viscosity of the radiation curable adhesive is preferably increased by such pre-curing during or after printing and before applying at least one transfer film to the first side of the first laminate film to a dynamic viscosity of 20 mPas to 3000 mPas, preferably 50 mPas to 1000 mPas, thereby providing the aforementioned advantages.

[0061] Optionally, the radiation-curable adhesive may be heated in a varnish bath at the corresponding printing station in order to reduce the viscosity to a range suitable for printing. After printing, the varnish cools and the viscosity increases again. During the application of at least one transfer film, the increased viscosity allows the printing details to be more easily preserved than in the case of a thinner adhesive. For example, it is heated to 30°C to 80°C, preferably 30°C to 60°C. Preferably, the radiation-curable adhesive is pre-cured by this curing step to about 10% to 50%, further to about 20% to 30%.

[0062] Furthermore, it is advantageous to cure the radiation-curable adhesive layer in a curing step, in particular to an extent of more than 50%, preferably more than 80%, after or during the application of the at least one transfer film to the first side of the first laminate film and before the at least one transfer film is peeled off from the first laminate film. The proportion of non-polymerizable monomers and / or oligomers is less than 50%, preferably less than 20%. The curing improves the adhesion between the decorative ply and the first laminate film and thus the peeling off of the decorative ply in the first partial region or regions. However, if a corresponding release layer is used for the transfer film and the interlayer adhesion of the radiation-curable adhesive layer and the decorative ply and / or the first laminate film is sufficient, said curing step may be omitted.

[0063] It is preferred that full curing of the adhesive layer is not yet achieved in the curing step for reasons described below.

[0064] More preferably, the radiation-curable adhesive layer is cured in a curing step after or during the peeling off of at least one transfer film from the first laminating film and before the lamination step to form the stack to a degree of curing of more than 80%, in particular 80% to 90%. Such a curing step allows the degree of curing of the radiation-curable adhesive layer to be set in a particularly targeted manner for the requirements of the lamination method, since when such a curing step is carried out, the carrier film has already been peeled off from the decorative layer and the edge areas of the radiation-curable adhesive layer are not covered by the border of the first and second partial areas of the laminating film and therefore irradiation can be carried out precisely in a correspondingly pinpoint-accurate and precisely set manner.

[0065] The mechanical and / or temperature dependent properties of the adhesive layer depend on the degree of cure, i.e. the degree of polymerization, as well as the formation of the adhesive, and therefore in part the thermoplastic properties of the adhesive may be present.

[0066] It is advantageous to not fully cure the radiation curable adhesive layer, but to cure it to about 50% to 90%. Thus, tests have shown that if the radiation curable adhesive layer is fully cured during lamination, the edges of the adhesive layer may break, and therefore the full protective function is not obtained. The incomplete cure of the radiation curable adhesive layer provides sufficient flexibility of the adhesive layer, and therefore improves the optical quality of the laminate.

[0067] Preferably, the radiation-curable adhesive layer is cured, particularly completely or about 80% to 95%, in a curing step after the lamination step.

[0068] More preferably, the curing steps are carried out by radiation sources, which are preferably arranged or aligned and assigned to each curing step. For the structure of the radiation sources, please refer to the above description. Furthermore, several curing steps may be combined as desired to carry out the method of the present invention, or the radiation-curable adhesive layer may be cured by one curing step.

[0069] Furthermore, it is particularly advantageous if the face of the first laminating film and / or the first face of the decorative ply has a surface roughness Ra of less than 3 μm, preferably less than 1.5 μm, more preferably less than 0.6 μm. Tests have shown that the selection of such a surface roughness improves the edge sharpness of the radiation-curable adhesive layer on the one hand and / or facilitates the complete transfer of the transfer ply, and further improves the optical appearance of the laminate on the other hand.

[0070] Preferably, the first and / or second laminate film is made of polycarbonate or has polycarbonate as a main component. The first and second laminate films are made of multiple layers, and may further have a layer of PET, GABS, or PVC, or may be formed from one of PET, GABS, and PVC. The thickness of the first and / or second laminate film is preferably 30 μm to 400 μm, particularly 40 μm to 130 μm. It is further preferred that the first and second laminate films are made of the same plastic material or mostly corresponding plastic materials at least on the surfaces facing each other, for example, when the first and second laminate films are made of polycarbonate. If different plastic layers are used in the first and second laminating films, e.g. PET, PC (polycarbonate), it is advantageous to use an adhesion-promoting layer, e.g. made from thermoplastic polyurethane (PU) or polyvinyl chloride (PVC) or acrylate, which improves the adhesion of the laminating film on the side facing the other laminating film during the lamination process.

[0071] Also advantageously, during the step of laminating a plurality of continuous films comprising a first laminating film having one or more first partial areas with a decorative ply and at least one second laminating film to form a laminate, the at least one second laminating film is made of polyvinyl chloride and is arranged on the side of the first face of the first laminating film and / or the plurality of continuous films comprises one or more further laminating films, in particular the first laminating film is made of polycarbonate. The one or more further laminating films comprise one or more of the following films: a first laminate film of the one or more further laminate films made of polyvinyl chloride and disposed on a side of the second surface of the first laminate film; a second laminate film of the one or more further laminate films made of polycarbonate and disposed on a side of the first laminate film of the one or more further laminate films facing the opposite side of the first laminate film; a third laminate film of the one or more further laminate films made of polyvinyl chloride and disposed on a side of the first laminate film and / or the second laminate film of the one or more further laminate films facing the opposite side of the first laminate film; and a fourth laminate film of the one or more further laminate films comprising polyvinyl chloride and disposed on a side of the second laminate film facing the opposite side of the first laminate film.

[0072] Films formed from and / or containing polycarbonate (PC) or polyvinyl chloride (PVC) preferably have polycarbonate or polyvinyl chloride as the main component, in particular have further components or consist entirely of polycarbonate or polyvinyl chloride.

[0073] In particular the second laminating film of the at least one or more further laminating films is provided with a decorative ply in one or more first partial regions of the second laminating film of the one or more further laminating films, preferably by a step of forming a first laminating film with one or more first partial regions provided with a decorative ply. Preferably, the second laminating film of the one or more further laminating films is used instead of the first laminating film in a corresponding step, in particular the decorative ply, the one or more first partial regions and / or the one or more second partial regions are designed differently.

[0074] In particular, the method may comprise the following steps for producing a laminate or a further laminate inlay: providing at least one laminate film of the one or more further laminate films, in particular a second laminate film of the one or more further laminate films made of polycarbonate and having a further first surface and an opposite further second surface.

[0075] Providing at least one further transfer film comprising a further carrier film and a further decorative ply peelable from the further carrier film, the transfer film having a further first surface facing an opposite side of the further carrier film and a further second surface facing the further carrier film.

In the one or more further second regions, the radiation-curable adhesive is preferably not applied to a further first surface of at least one laminate film of the one or more further laminate films, in particular to a further first surface of a second laminate film of the one or more further laminate films and / or to a further first surface of a further decorative ply.

[0077] Applying at least one further transfer film to a further first surface of at least one laminating film of the one or more further laminating films, in particular to a further first surface of a second laminating film of the one or more further laminating films. Advantageously, at least one partial area of ​​the one or more further first zones provided with a further radiation-curable adhesive layer and at least one partial area of ​​the one or more further second zones not provided with a further radiation-curable adhesive layer are arranged between the further first surface of the further decorative ply and the further first surface of the at least one laminating film of the one or more further laminating films, in particular to a further first surface of a second laminating film of the one or more further laminating films.

[0080] For the production of the laminate, the following steps may furthermore be included: in particular optionally laminating a plurality of continuous films comprising a first laminating film having one or more first partial regions with a decorative ply, at least one second laminating film and / or one or more further laminating films, in particular a first laminating film of the one or more further laminating films, preferably a second laminating film of the one or more further laminating films having one or more second partial regions with a further decorative ply, a third laminating film of the one or more further laminating films and / or a fourth laminating film of the one or more further laminating films to form the laminate.

[0081] The details for the radiation-curable adhesive layer are preferably applied to a corresponding further radiation-curable adhesive layer and / or the details for the decorative ply of the first laminate film are applied to a further decorative ply of at least one of the one or more further laminate films, in particular a second laminate film of the one or more further laminate films.

[0084] Furthermore, one or more further laminate films made of polyvinyl chloride and / or polycarbonate may be arranged on and / or between the first laminate film, the at least one second laminate film and / or the one or more further laminate films, and may be laminated to form a laminate, in particular during the lamination of a plurality of continuous films comprising a first laminate film having one or more first partial regions with a decorative ply and at least one second laminate film, to form a laminate.

[0085] The additional decorative ply may be applied to one or more laminating films of one or more further laminating films, in particular to a first laminating film of the one or more further laminating films, preferably comprising polycarbonate, thereby forming in particular one or more additional laminate inlays. The details and / or descriptions of the first laminating film and the decorative ply also preferably apply to the corresponding additional laminating film and the corresponding additional decorative ply. To this end, in particular the additional laminate inlay has an additional radiation-curable adhesive layer, an additional first partial region comprising the additional decorative ply, and / or an additional second partial region.

[0086] Furthermore, it is preferred that the first laminate film, the at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films, are transparent, translucent and / or opaque at least over a portion or the entire surface, in particular transparent being translucent and / or opaque in the wavelength range visible to the human eye.

[0087] Transparent preferably means a transmittance of 50% to 99%. Furthermore, semi-transparent preferably means a transmittance of 30% to 50%. Opaque preferably means a transmittance of 0% to 30%.

[0088] Furthermore, the first laminate film, the at least one second laminate film and / or one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more further laminate films, in particular the second laminate film of the first and / or one or more further laminate films, may be opaque, semi-transparent and / or transparent over a portion of their surface or over their entire surface and / or may be formed to be opaque, semi-transparent and / or transparent in the UV range and / or in the IR range, in particular in the wavelength range of 9400 nm to 10600 nm and / or in the wavelength range of 946 nm to 1444 nm, preferably at a wavelength of 1064 nm.

[0089] Preferably, at least one laminate film selected from the following films is laser processable: the first laminate film, at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films, and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films. In particular, the first laminate film and / or the second laminate film of the one or more further laminate films can be laser processed. Advantageously, the first laminate film, the at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films, and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films, are mechanically machined, preferably individualized, after lamination, by a laser, in particular a Nd:YAG laser, to form a laminate.

[0090] The laser processable laminate film, in particular the first laminate film, at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the second laminate film of the first and / or one or more further laminate films, is preferably opaque over at least a portion of said surface in the laser wavelength range, for example in the wavelength range of 946 nm to 1444 nm, preferably at a wavelength of 1064 nm. The plies arranged above and / or below the laser processable ply are preferably transparent in the respective laser wavelength range.

[0091] Preferably, the laser processing is performed via the one or more first partial regions and / or the one or more further first partial regions, so that the laser processed partial regions are arranged in exact registration over and / or under and / or adjacent to the decorative ply and / or the further decorative ply in the one or more first partial regions and / or the further decorative ply in the further first partial region, in particular when viewed perpendicularly to a plane across the first laminating film, preferably in the direction from the second laminating film to the first laminating film, and / or are arranged on the further decorative ply in the further first partial region.

[0092] In particular when the decorative ply and / or the further decorative ply and / or the additional decorative ply form a security feature, it is advantageously possible for the laser processing to be precisely registered in relation to the decorative ply and / or the further decorative ply and / or the additional decorative ply, ensuring a particularly high level of protection against counterfeiting.

[0093] Preferably, the laser processed partial areas are patterned and designed. Preferably, the laser processed partial areas have a grayscale image via a halftone raster generated by the laser. Furthermore, the grayscale image can have a particularly high quality resolution and / or a large number of grayscales due to the laser processing, in particular in comparison with conventional laminates of films made of polyvinyl chloride.

[0094] In the present specification, a "grayscale image" preferably means an image which assigns to each image point of a motif a respective color value in the form of a corresponding grayscale or brightness value of the assigned color channel. These grayscale or brightness values ​​may in each case in particular be generated by fine rasterization of binary raster points. The raster points preferably generate the impression of a grayscale or brightness value for the human eye. Preferably, the grayscale image is easily detectable by a human observer and / or by a viewing device. For example, it is envisaged to cast a portrait of the owner of a security document on or within the security document.

[0095] The advantage arises that the first laminate film, in particular made of polycarbonate, the one or more laminate films of the one or more further laminate films, in particular the second laminate film of the one or more further laminate films, and / or the one or more further laminate films, in particular the first and / or second laminate films of the one or more further laminate films, in particular made of polycarbonate and which are, for example, opaque, in particular in the IR laser range, and / or have individualizability and mechanical and / or thermal resistance, perform multiple functions.

[0096] For example, other films and / or plastic plies, such as films formed from polyvinyl chloride, are less advantageously suited. In particular, rendering of grayscale images is more advantageous with laser processing laser-machinable PC than with laser processing laser-machinable PVC, since monochrome binary images are more easily produced with laser-machinable PVC.

[0097] However, laser processing may be performed before and / or after lamination of multiple continuous films including a first laminate film having one or more first partial regions with a decorative ply and at least one second laminate film to form a laminate.

[0098] In particular, for the plastics polycarbonate (PC) and polyvinyl chloride (PVC), the following arrangements are possible: PVC / PC / PVC and / or PVC / PVC / PC / PVC / PVC and / or PVC / PC / PVC / PC / PVC and / or PVC / PVC / PC / PVC / PC / PVC / PVC. For example, the following layer structures are envisaged: - an optional fourth laminate film of one or more laminate films made of PVC, - a second laminating film made of PVC, - a first laminating film, a first laminate film of one or more further laminate films made of PVC, - optionally a second laminate film of one or more further laminate films made of PC, - optionally a third laminating film of one or more further laminating films made of PVC, - Optionally, one or more additional laminating films made of PVC.

[0099] In particular, the first laminate film and / or the one or more further laminate films, in particular the first laminate film of the one or more further laminate films, may be monolayer or multilayer. In particular, it has been found desirable for the first laminate film of the one or more further laminate films to have one or more layers of polyvinyl chloride and / or to act as an adhesion promoter between the first laminate film and the second laminate film of the one or more further laminate films.

[0100] In particular, during the lamination process of a plurality of continuous films, including a first laminate film having one or more first partial regions with a decorative ply and at least one second laminate film, to form a laminate, it is advantageous for at least two laminate films made of polycarbonate to be bonded (joined) to one another via an adhesive layer and / or at least one layer of polyvinyl chloride.

[0101] That is to say, in particular, two laminating films made of polycarbonate should preferably not be directly adjacent to each other, since a sufficient bonding, in particular a material bond, of the films made of polycarbonate is not desirably obtained during the lamination process, and therefore, in order to achieve a particularly stable bond, it is preferred that the films made of polycarbonate are alternated with films made of polyvinyl chloride and / or adhesive layers.

[0102] For transmission properties preferably in the wavelength range visible to the human eye, arrangements having the following structure are particularly contemplated: an optional transparent fourth laminating film of one or more further laminating films, - a transparent second laminating film, - a printed opaque first lamination film, a transparent first laminating film of one or more further laminating films, an optional transparent third laminating film of one or more further laminating films, or - A transparent second laminating film -Transparent first lamination film an opaque first laminating film onto which one or more further laminating films are printed, a transparent second laminating film of one or more further laminating films, - a transparent third laminating film of one or more further laminating films.

[0103] One or more further laminate films, preferably transparent and / or formed from polyvinyl chloride, may be preferably disposed outermost.

[0104] Preferably for the first laminating film and / or for the first laminating film of the one or more further laminating films, transparency and / or an arrangement, in particular a symmetrical arrangement, of the plastic material is possible.

[0105] The benefits of a symmetrical arrangement of plastic materials include reduced laminate distortion and improved decorative ply quality, which, for example, allows for greater registration accuracy and provides increased protection against counterfeiting.

[0106] However, an asymmetric arrangement is also possible.Preferably, at least the outermost films of the laminate comprise polyvinyl chloride.

[0107] The decorative plies, in particular the decorative plies, the further decorative plies and / or the additional decorative plies, are preferably not used to determine the arrangement and / or transfer characteristics of the plastic material or are not taken into account in the arrangement, so that when considering the material of the decorative plies, the advantages of the arrangement also apply to an arrangement of materials that is totally asymmetric.

[0108] Further envisaged arrangements, in particular with regard to the plastic material of the laminate film, are e.g.: - a second laminating film made of PVC, - a first lamination film made of PC, a first laminate film of one or more further laminate films made of PVC, a third laminate film of one or more further laminate films made of PVC.

[0109] In particular, one envisaged arrangement for the transfer properties of the laminate film, preferably in the wavelength range visible to the human eye, is, for example: - a transparent second laminating film, - a transparent first laminating film, a first laminating film of one or more further laminating films, preferably opaque, to be printed, a third lamination film of one or more transparent further lamination films.

[0110] Further envisaged arrangements, in particular for the plastic material of the laminate film, are e.g.: - a second laminating film made of PVC, - a first lamination film made of PC, a first laminate film of one or more further laminate films made of PVC, - a second laminate film of one or more further laminate films made of PC, a third lamination film of one or more further lamination films made of PVC, a first laminate film of one or more further laminate films made of PC, a second laminate film of one or more further laminate films made of PVC.

[0111] In particular, the third laminating film of the one or more further laminating films may be monolayer or multilayer. It has proven to be particularly advantageous if the third laminating film of the one or more further laminating films has one or more layers of polyvinyl chloride and / or acts as an adhesion promoter between the second laminating film of the one or more further laminating films of polycarbonate and the first laminating film of the one or more further laminating films of polycarbonate.

[0112] In particular, one envisaged arrangement for the transfer properties of the laminate film, preferably in the wavelength range visible to the human eye, is, for example: - a transparent second laminating film, - a transparent first laminating film, a first laminating film of one or more further laminating films, preferably opaque, to be printed, a second lamination film of one or more transparent further lamination films, a third lamination film of one or more transparent further lamination films, a first laminating film of one or more transparent further laminating films, a second lamination film of one or more transparent further lamination films.

[0113] It is especially advantageous to have at least two outer films made of polyvinyl chloride with at least one film made of polycarbonate arranged between the films made of polyvinyl chloride. The advantages of a laminate made entirely of polycarbonate are compared with those of a laminate made entirely of polyvinyl chloride via the corresponding laminates. In particular, the manufacturing method is the same or similar to that of a laminate made entirely of polycarbonate, so that manufacturers, especially card manufacturers, can enjoy the advantages of a laminate made of polycarbonate without changing the manufacturing process for polycarbonate. The processing cycle of a laminate made of polyvinyl chloride is usually shorter than that of a laminate made of polycarbonate, so that productivity is maintained. Furthermore, material and / or energy costs can be reduced, especially compared to a laminate made entirely of polycarbonate. This allows a manufacturing process that is especially cost-effective and environmentally friendly in terms of the energy resources used. In particular, the first laminating film and / or the second laminating film of the one or more further laminating films made of polycarbonate increases the mechanical stability of the laminate, so that the applied security element, for example having optically variable elements, appears particularly bright.

[0114] Advantageously, the release layer and / or protective layer is arranged on the outermost side of the decorative ply, the further decorative ply and / or the additional decorative ply, facing the opposite side of the radiation-curable adhesive layer, the further radiation-curable adhesive layer and / or the additional radiation-curable adhesive layer. The release layer and / or protective layer preferably forms the outermost layer of the decorative ply, the further decorative ply and / or the additional decorative ply and / or is bonded, in particular in direct contact and / or bonded by a material bond and / or laminated together with a laminate film made of polyvinyl chloride, in particular the first laminate film, at least one second laminate film, one or more laminate films of one or more further laminate films, in particular the first, second, third and / or fourth laminate film of one or more further laminate films and / or one or more laminate films of one or more further laminate films, in particular the first and / or second laminate film of one or more further laminate films, when a plurality of continuous films, in particular comprising a first laminate film having one or more first partial regions with a decorative ply and at least one second laminate film, are laminated to form a laminate.

[0115] It is therefore preferred that the decorative ply, the further decorative ply and / or the additional decorative ply, in particular at least one outermost layer of the release layer and / or the protective layer of the decorative ply, the further decorative ply and / or the additional decorative ply, have a softening temperature lower than or in the softening temperature range of the first laminating film, at least one second laminating film and / or one or more laminating films of the one or more further laminating films, in particular the first, second, third and / or fourth laminating film of the one or more further laminating films and / or one or more laminating films of the one or more further laminating films, in particular the first and / or second laminating film of the one or more further laminating films made of polyvinyl chloride, and / or soften below the lamination temperature or in the lamination temperature range.

[0116] Preferably, the softening temperature of at least one outermost layer of the decorative ply, the further decorative ply and / or the additional decorative ply, in particular the release layer and / or the protective layer of the decorative ply, the further decorative ply and / or the additional decorative ply, measured according to the VICAT A (10N) test method, particularly preferably at a heating rate of 50 K / h, is preferably in the softening temperature range of polyvinyl chloride and / or is higher than 60°C, preferably higher than 80°C, particularly preferably higher than 100°C.

[0117] This ensures good bonding of the decorative ply, the further decorative ply and / or the outermost layer of the additional decorative ply, in particular the release layer and / or protective layer of the decorative ply, the further decorative ply and / or the additional decorative ply to a laminate film made of polyvinyl chloride, in particular the first laminate film, at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films.

[0118] Advantageously, the decorative ply, the further decorative ply and / or the additional decorative ply, in particular the outermost layer of the release layer and / or the protective layer of the decorative ply, the further decorative ply and / or the additional decorative ply provided with the release layer and / or protective layer, are protected, so that in particular the optical effect is maintained and in particular a high reliability in handling and a high level of protection against counterfeiting are ensured.

[0119] Furthermore, the adhesive layer, in particular the radiation-curable adhesive layer, the further radiation-curable adhesive layer and / or the additional radiation-curable adhesive layer may soften with a softening temperature of 50°C to 150°C, in particular 60°C to 140°C, and / or the adhesive layer, preferably the radiation-curable adhesive layer, the further radiation-curable adhesive layer and / or the additional radiation-curable adhesive layer may have a softening temperature of 50°C to 150°C, preferably 70°C to 120°C, particularly preferably 80°C to 110°C, measured in particular according to the VICAT A (10N) test method, preferably at a heating rate of 50 K / h.

[0120] Softening temperature, in particular softening temperature according to VICAT A and VICAT B, means the VICAT softening temperature VST (VICAT softening temperature) according to DIN EN ISO 306 (predecessor DIN 53460).

[0121] A piercing needle (1 mm) was used for measurement. 2 A test load of 10 N (VICAT A) or 50 N (VICAT B) is applied to this. The test specimens have a permissible thickness of 3 mm to 6.4 mm and are heated at a heating rate of 50 K / h or 120 K / h. The VST is reached when the penetrator reaches a penetration depth of 1 mm.

[0122] The variation of boundary conditions results in four combinations of parameters, preferably: VST / A / 50, VST / A / 120, VST / B / 50, VST / B / 120, where "A" stands for a test load of 10 N and "B" stands for a test load of 50 N. 50 or 120 is preferably the heating rate, expressed in [K / h].

[0123] The lamination temperature, i.e. the desired processing temperature prevailing in the laminate during the lamination process, is in particular higher than the softening temperature of polyvinyl chloride and in particular lower than the softening temperature of polycarbonate. The lamination temperature is in particular the highest temperature reached in the laminate during the lamination process.

[0124] Furthermore, the first laminate film, the at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films, may comprise polycarbonate and have a softening temperature, preferably a softening temperature of more than 100°C, preferably a softening temperature of more than 120°C, particularly preferably a softening temperature of more than 140°C according to VICAT B (50N), in particular at a heating rate of 50 K / h.

[0125] Furthermore, the first laminate film, the at least one second laminate film and / or one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the second laminate film of the first and / or one or more further laminate films, may comprise polyvinyl chloride and may have a softening temperature of more than 60°C, preferably more than 80°C, particularly preferably more than 100°C, preferably according to VICAT A (10N), in particular with a heating rate of 50 K / h, and / or may have a softening temperature of more than 50°C, preferably more than 80°C, particularly preferably more than 100°C, preferably according to VICAT B (50N), in particular with a heating rate of 50 K / h.

[0126] In particular, the adhesive strength between a laminate film made of PVC and a laminate film made of PC will be described below.

[0133] In the following, it is particularly described that the adhesion between a laminate film made of polyvinyl chloride and a laminate film made of polycarbonate is greater than the adhesion between the laminate film made of polyvinyl chloride and the decorative ply, and / or is greater than the adhesion between a laminate film made of polycarbonate and the decorative ply, and / or is greater than the adhesion between the two plies and / or layers of the decorative ply.

[0134] Furthermore, in particular by peel test, it is possible to determine the peelability of the first laminate film, the at least one second laminate film and / or one or more further laminate films, in particular the fourth laminate film of the first, second, third and / or one or more further laminate films and / or one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films consisting of polycarbonate, in particular the first laminate film, the at least one second laminate film and / or one or more further laminate films, in particular the fourth laminate film of the first, second, third and / or one or more further laminate films and / or one or more further laminate films, in particular the one or more further laminate films consisting of polyvinyl chloride. The adhesion at the interface between the first and / or second laminate film of the laminate film may be higher than the adhesion at the interface between the first laminate film, the at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films, and a decorative ply, a further decorative ply and / or an additional decorative ply that is preferably bonded to the corresponding laminate film and / or may be higher than the adhesion at the interface between two plies and / or between layers of a decorative ply, a further decorative ply and / or an additional decorative ply that is preferably bonded to the corresponding laminate film.

[0135] Furthermore, the adhesion at the interface between the first laminate film, the at least one second laminate film and / or one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films, and the decorative ply, further decorative ply and / or additional decorative ply, preferably bonded to the corresponding laminate film, may be higher than the adhesion at the interface between the layers of the two plies and / or the decorative ply, further decorative ply and / or additional decorative ply, preferably bonded to the corresponding laminate film, in particular by peel test.

[0136] By corresponding laminate film is meant in particular a first laminate film, at least one second laminate film and / or one or more laminate films of one or more further laminate films, in particular a first, second, third and / or fourth laminate film of one or more further laminate films and / or one or more laminate films of one or more further laminate films, in particular the first and / or second laminate films of one or more further laminate films, which comprise polycarbonate and / or polyvinyl chloride.

[0137] This would require any attempt to dig through the decorative ply to tear it apart, which is advantageous, for example, if the decorative ply is a security feature, as it makes counterfeiting more difficult and therefore provides increased protection against counterfeiting.

[0138] Also, the interface is preferably a surface located where the interface was located immediately prior to the joining of the two plies.

[0139] The peel test is preferably a measurement method according to ISO / IEC 10373-1, paragraph 5.3. In particular, the optionally preconditioned card is cut into test pieces 10 mm wide.

[0140] For example, all plies on one side of the decorative ply are removed, preferably with a length of 5 mm to 10 mm. Thus, for example with a sharp blade, the decorative ply, in particular the laminate film over the security feature, preferably KINEGRAM®, is peeled from the core, i.e. in particular from the laminate film and the decorative ply forming the security feature, preferably KINEGRAM®. The peeling (stripping) is done in parts.

[0141] The peeled end is then fixed to the holder of the tensile tester, preferably via a fixing clamp or adhesive tape. It is preferred that the peeled and fixed laminate film on the tensile tester and the unpeeled laminate film are at right angles. In particular, the first laminate film and the second laminate film are at right angles. The bottom of the card, in particular the first laminate film of the one or more further laminate films, is optionally fixed on a stabilizer for convenience.

[0142] During the tensile measurement, the peeled film layers, thus at least the first laminate film with the corresponding decorative ply and the first laminate film of one or more further laminate films, are preferably guided over a roller. The adhesion (peel strength) is preferably plotted on a graph for evaluation. The first and last 5 mm of the measurement are preferably not taken into account. The results are expressed, for example, in N / 10 mm.

[0143] Measurements may also be taken at locations where no decorative ply is provided, preferably to measure adhesion between a laminate film comprising polycarbonate and a laminate film comprising polyvinyl chloride.

[0144] Furthermore, the following steps may be carried out during and / or before the lamination step of the multiple continuous films, preferably having a first laminate film having one or more first partial regions provided with a decorative ply and at least one second laminate film, to form a laminate: providing a hinge and bonding, in particular laminating, the hinge and the first laminate film, the at least one second laminate film and / or one or more laminate films of the one or more further laminate films, in particular the first, second, third and / or fourth laminate film of the one or more further laminate films and / or one or more laminate films of the one or more further laminate films, in particular the first and / or second laminate film of the one or more further laminate films. The hinge is preferably arranged between the first and second laminate films of the one or more further laminate films and / or between the third and / or second laminate films of the one or more further laminate films and the fourth and / or second laminate films of the one or more further laminate films. In particular, the hinge is preferably arranged adjacent to the first and / or second laminate films of the one or more further laminate films and / or the first laminate film of the one or more further laminate films when viewed perpendicularly to a plane spanning the first and / or second laminate films of the one or more further laminate films.

[0145] The hinge preferably comprises at least one ply formed from polyvinyl chloride, thermoplastic polyurethane and / or textile tape. The hinge is preferably coated with polyvinyl chloride, so that, in particular during bonding, in particular during lamination of the hinge, the polyvinyl chloride is directly bonded, in particular materially bonded, to the adjacent laminate films, layers and / or plies.

[0146] The hinge is preferably a part which provides a connection between the laminate and, more preferably, the planar body. For example, the hinge is a part which connects the data page, preferably the laminate as the passport card of the passport booklet, to the seam of the passport booklet, especially with a hard cover, preferably to the remaining pages of the passport booklet. In particular, the data page is therefore attached to the passport booklet by a "hinge", i.e. preferably via a flexible narrow strip in the laminate or the data page. The hinge serves as a flexible hinge and a connecting element in the seam area of ​​the passport booklet. Preferably, non-textile hinges and / or textile, especially woven or non-woven hinges, made of PVC and / or TPU (TPU=thermoplastic polyurethane) and / or TPE (TPE=thermoplastic elastomer), especially formed over the entire surface and / or having through holes, are used.

[0147] The hinge may, for example, be adjacent to the first laminate film and / or the second laminate film of the one or more further laminate films and / or the first laminate film of the one or more further laminate films. The hinge and the second laminate film and / or the fourth laminate film of the one or more further laminate films and / or the third laminate film of the one or more further laminate films and / or the second laminate film of the one or more further laminate films preferably at least partially overlap and / or are in direct contact. Furthermore, the hinge and the first laminate film and / or the second laminate film of the one or more further laminate films and / or the first laminate film of the one or more further laminate films may or may not be in direct contact.

[0148] It has proven to be further advantageous if the first and / or second face of the first and / or second laminating film has a gloss at an angle of 60° according to ESAO 2813 of at least 90%, preferably at least 98%. Tests have shown that with the selection of such a gloss, the optical and / or mechanical disturbances in the decorative ply are further reduced during the lamination process.

[0149] It is beneficial to pre-treat a too rough surface to provide a sufficiently smooth and suitable surface for a clear printing result. For this purpose, a thinly applied adhesive layer and / or primer layer and / or adhesion promoter layer and / or pre-embossing by hot or cold stamping and / or for example heat treatment and / or calendaring are appropriate. Furthermore, such coatings or treatments are applied in register with respect to the decorative ply, so that the properties of the laminate in the non-decorative areas are not affected.

[0150] It is furthermore advantageous if the radiation-curable adhesive layer is dyed, in particular semi-transparently, with a dye or pigment. Additional optical effects can be produced by the radiation-curable adhesive layer. Effect pigments can also be introduced which, for example, fluoresce under UV irradiation or reflect at different wavelengths under IR irradiation.

[0151] It is further advantageous if some first surface areas are defined by printing an adhesive layer on the first laminating film and some first surface areas are defined by printing an adhesive layer on the transfer film, the adhesive layers having different properties, for example different mechanical properties after curing, different pigments and dyes or no pigments and dyes, which results in different properties being registered with the part of the transfer ply partially transferred in the first surface areas.

[0152] The one or more first partial regions are arranged as one or more motif regions. These motif regions are preferably delimited by imaginary and / or visible contours. Any desired number of first and second surface regions may be provided within the motif region.

[0153] The motif region or regions preferably comprise one or more motifs formed in the decorative ply, which is preferably formed transparent in one or more first partial regions, respectively, outside the motif or motifs. Transparent, as used herein, preferably means a transparency of more than 80%, preferably more than 90%, in the wavelength range visible to a human observer.

[0154] At least one transfer film preferably has a release layer arranged between the carrier film and the decorative ply, which allows the desired release force between the carrier film and the decorative ply to be set, resulting in sharp edges and high resolution, especially for the transfer area of ​​the decorative ply.

[0155] Preferably, the release layer is part of the transfer ply to be transferred. The release is preferably achieved by one or more thin wax layers (layer thickness of 0.01 to 0.2 micrometers) between the carrier film and the release layer, so that the release layer is peeled off from the carrier ply. In particular, the release layer is formed so as to obtain good adhesion to the second laminate film in the laminate. Preferably, the decorative ply has one or more decorative layers. The decorative layers are provided over the entire surface or over a part of the decorative ply.

[0156] Preferably, the decorative layer or layers are one or more of the following layers: "HRI layers" (HRI = high refractive index) can be used as decorative layers. HRI layers are relatively high refractive index dielectric layers, which have a high refractive index and are usually almost transparent in the visible wavelength range from 400 nm to 700 nm. Preferably, the refractive index of such HRI layers is higher than 1.6, preferably higher than 1.8. Such HRI layers can be, for example, ZnS or TiO2 or SiO2 applied by vacuum deposition. x Also high refractive index polymer layers, especially those rich in nanoparticles, may be used. Such polymer layers may be printed and / or evaporated.

[0157] The decorative layer is, for example, a metal layer made of aluminum (Al), silver (Ag) or copper (Cu) or chromium (Cr). This metal layer may be provided in the decorative ply as an opaque, semi-transparent or transparent metal layer. The transparency of the metal layer is set by a corresponding selection of the layer thickness of the metal layer and / or by a corresponding rastering of the metal layer. Furthermore, the decorative ply may have several metal layers of different materials and / or with different transparencies.

[0158] The decorative layer may be a varnish layer containing dyes and / or pigments. The decorative ply may have different such varnish layers containing different dyes and / or pigments. These varnish layers are arranged one above the other and / or adjacent to each other. Furthermore, the dyes and / or pigments may be luminescent and / or phosphorescent dyes and / or pigments. In particular, the use of transparent, translucent or opaque optically variable pigments with color-changing effects, such as thin film layer pigments or liquid crystal pigments, which are rearranged by magnetic and electric fields and give rise to complex optically variable effects, is further advantageous. Furthermore, the use of thermochromic and / or electrochromic dyes and / or pigments in the decorative layer is also advantageous.

[0159] Furthermore, the decorative layer may consist of an electrically conductive or magnetic layer, such as a layer made of electrically conductive and / or magnetic materials, such as metallic materials, conductive polymers, conductive or magnetic pigments or particles incorporated in a binder matrix.

[0160] The decorative layer may be a volume holographic layer, for example a photopolymer layer, which is provided (imprinted) with a transmission and / or reflection hologram by means of a holographic master.

[0161] The decorative layer may also be a relief layer which comprises an introduced, especially a molded, surface relief.

[0162] Preferably, this relief layer consists of a thermoplastic and / or a UV-curable plastic. A corresponding surface relief is molded in the relief layer, in particular by thermal and / or UV replication with a replication tool. The surface relief can also be introduced by means of a laser. The relief layer can also be a photosensitive layer. The surface relief is introduced in the relief layer by exposing it to light, exposing it to patterns of different brightness and then, depending on the type of photosensitivity, washing away or dissolving the exposed or non-exposed areas of the relief layer, in particular by means of a solvent.

[0163] Preferably, the relief layer does not soften during lamination of a plurality of successive films with a first laminating film having one or more first partial regions with a decorative ply and at least one second laminating film to form a laminate. In particular, the softening temperature of the relief layer is higher than the lamination temperature. The softening temperature of the relief layer, measured in accordance with the test method VICAT A (10N), in particular at a heating rate of 50 K / h, is preferably higher than 60° C., preferably higher than 100° C., particularly preferably higher than 130° C.

[0164] This ensures that the relief layer and in particular the structure moulded into it remains stable during the lamination process, e.g., the shine of the decorative ply is preserved by preserving the moulded relief structure and ensures a particularly high level of protection against counterfeiting.

[0165] Preferably, one of the following surface reliefs or a combination of two or more of the following surface reliefs is provided as surface relief: diffractive surface relief, holographic surface relief, first order diffraction grating, zero order diffraction structure, blazed diffraction grating, achromatic surface relief, lenses and / or lens rasters, surface relief in the form of micromirror arrays, microprisms, microfacets or freeform surfaces, matt structures, in particular isotropic or anisotropic matt structures.

[0166] Preferably, the relief layer has different partial areas in which different surface reliefs are formed, in particular with one or more different relief parameters and / or consisting of different surface reliefs among said plurality of surface reliefs, said plurality of surface reliefs may also overlap one another.

[0167] More preferably, the decorative ply comprises one or more adhesion-promoting and / or barrier and / or stabilizing and / or protective layers, which may likewise be present on the decorative ply over the entire surface or partially.

[0168] Preferably, the stabilizing layer only slightly softens during lamination of a plurality of successive films, including a first laminating film with one or more first partial regions with a decorative ply and at least one second laminating film, to form a laminate. In particular, the softening temperature of the stabilizing layer is higher than the lamination temperature. In particular, the softening temperature of the stabilizing layer, measured according to the test method VICAT A (10N), preferably at a heating rate of 50 K / h, is preferably higher than 60° C., preferably higher than 100° C., particularly preferably higher than 130° C.

[0169] This maintains the stability of the stabilizing layer during lamination of a plurality of successive films, including a first laminating film having one or more first partial regions with a decorative ply and at least one second laminating film, to form a laminate, and in particular preserves the shine of the decorative ply.

[0170] The decorative ply may in particular have a combination of at least one layer applied over the entire surface and at least one partially formed layer. For example, the layer applied over the entire surface is a transparent protective layer and / or a particularly transparent stabilizing layer and / or a particularly transparent adhesion promoting layer and / or a transparent or translucent HRI layer. The partially formed layer forms at least one motif, in particular a pattern and / or a graphic and / or a code and / or one or more alphanumeric characters. For example, the at least one partially formed layer is a metal layer and / or a color layer and / or an HRI layer.

[0171] The full-surface applied layer of decorative ply is preferably entirely transparent and is formed to completely overlap the partially applied layer and to overlap on all sides.

[0172] Each motif in at least one, and preferably all, planar dimensions is preferably formed smaller than the motif area of ​​the radiation curable adhesive layer.

[0173] Preferably, the decorative ply is applied to the radiation-curable adhesive in such a way that the motif areas of the radiation-curable adhesive layer protrude beyond the motifs of the decorative ply in at least one planar dimension, preferably on all sides. This means that in each motif area the complete motif is transferred and the surface areas of the decorative ply are formed transparent and protrude. These surface areas formed transparent do not in particular substantially appear optically after transfer of the decorative layer, so that the motif is transferred substantially without visible edges.

[0174] Preferably, not only one transfer film and / or radiation curable adhesive, but two or more transfer films and / or radiation curable adhesives are used during the production of the laminate inlay or laminate. Thus, the steps of applying said at least one transfer film, peeling off said at least one transfer film and optionally printing the radiation curable adhesive are preferably repeated several times. This allows different optical effects brought about by different decorative plies of different transfer films and / or different radiation curable adhesives to be efficiently and cost-effectively combined with each other in the laminate inlay or laminate, without having to take into account the different application processes required in each case.

[0175] The decorative plies of different transfer films may be provided adjacent to one another, partially or completely overlapping, on the first laminate film.

[0176] It is therefore advantageous to provide two or more transfer films as the at least one transfer film, to apply the two or more transfer films to the first side of the first laminate film, and to peel the transfer film from the first laminate film. As a result, in one or more first partial regions, the decorative ply of at least one of the two or more transfer films is peeled off from the carrier film and remains on the first side of the first laminate film. A radiation-curable adhesive is printed on the first side of the laminate film in one or more first areas assigned simultaneously or sequentially. A laminate film is then applied simultaneously or sequentially to the first side of the first laminate film. The carrier film of the transfer film is then peeled off simultaneously or sequentially. Furthermore, two or more transfer films may be glued to the first side of the first laminate film and the transfer film may be applied simultaneously or sequentially to the first side of the laminate film.

[0177] It is particularly advantageous if two or more transfer films have different decorative layers, in particular with respect to the decorative layer or the shaping of the decorative layer. Thus, for example, a first transfer film may have a decorative layer with a varnish layer containing pigments and / or dyes, in particular optically variable pigments and / or dyes. A second transfer film may have a relief layer with an introduced diffractive relief structure and an HRI layer. Furthermore, a third transfer film may have, for example, one or more translucent and / or opaque metal layers, in particular a decorative layer with a shaped pattern. The third transfer film may also additionally have a relief layer with an introduced diffractive relief structure.

[0178] It is particularly advantageous if not only one first partial area, but two or more first partial areas, in particular a group comprising several first partial areas, are peeled off from the respective transfer film and the different decorative plies of such a group of first partial areas are transferred to a first laminate film adjacent to and / or overlapping each other. Preferably, these two or more groups of first partial areas form partial motifs of a total motif or repeat items of information in different optical designs. This allows the items of information generated by the different decorative plies to be "woven" together, further improving the protection against counterfeiting.

[0179] Furthermore, it is advantageous if one or more coats, in particular registration marks, varnish layers, colour layers, layers containing pigments and / or dyes, in particular optically variable pigments, luminescent substances, conductive coats and magnetic coats are printed on the first side of the first and / or second laminate film and / or on the decorative layer, which further improves the protection against counterfeiting.

[0180] Furthermore, the laminate film may already have various features applied in a previous step prior to the transfer of the decorative ply, such as a further applied transfer ply and / or overprint and / or apertures and / or perforations (holes) and / or markings, etc. It is particularly advantageous to apply the decorative ply in register with these features by means of a radiation curable adhesive.

[0181] Furthermore, in subsequent steps after the transfer of the decorative ply, various features may be applied and / or introduced into the laminate film, such as further applied transfer plies and / or overprints and / or apertures and / or perforations (holes) and / or markings, etc. It is particularly advantageous to repeatedly apply these features to the decorative ply.

[0182] It is further advantageous to carry out one or more of the following steps during the production of the laminate or laminate film: cleaning the first side of the first and / or second laminate film, in particular before printing the radiation-curable adhesive and before laminating or applying the transfer film; introducing perforations into the first side of the first and / or second laminate film and / or the decorative layer; carrying out a surface treatment, in particular by corona treatment and / or plasma treatment, on the first side of the first and / or second laminate film and / or the decorative layer, in particular before printing the radiation-curable adhesive layer or before carrying out the lamination; annealing the laminate, the first laminate film, the second laminate film or the laminate inlay; finishing and / or cutting the laminate, the first laminate film and / or the second laminate film.

[0183] The invention will now be described with reference to a number of embodiments thereof as illustrated in the accompanying drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0185] Figure 1 shows the basic layer structure of a laminate 1. The laminate 1 is in particular made in the form of a card, for example a bank card, an identity card or credit card or a banknote or a security document, for example an insert page of a passport booklet.

[0186] The laminate 1 has a plurality of continuous films laminated by a lamination method to form a laminate, of which a plurality of laminate films 22 to 27 and a laminate inlay 2 are shown in FIG.

[0187] The laminate inlay 2 comprises a laminate film 21 having a first side 211 and a second side 212 located opposite said first side. In a first partial region 31 of the first side 211 of the laminate film 21, at least one decorative ply is provided which is peeled off from the carrier film of at least one transfer film, and a radiation-curable adhesive layer is provided. The radiation-curable adhesive layer is arranged between the decorative ply and the first side 211 of the laminate film 21 and is at least partially cured. In a second partial region 32, the at least one decorative ply is not provided on the first side 211 of the laminate film 21 and is peeled off together with the carrier film.

[0188] Preferably, the laminating films 21-27 consist of thermoplastic films, which at least partially melt under the conditions of the laminating method used, so that during the laminating method the faces of the superposed laminating films melt (fuse) with one another at least partially, preferably over the entire surface, thereby achieving a layer bond between the layers of the laminate 1, which provides a particularly high degree of protection against counterfeiting and resistance to environmental influences.

[0189] It is preferred that at least some of the laminating films 21-27, preferably all of the laminating films 21-27, consist of polycarbonate. Thus, preferably, the laminate 1 has polycarbonate as the main component. Such a laminate is characterised by a particularly high resistance to scratches, abrasion and chemicals, and by a particularly good interlayer adhesion, and therefore has a much better suitability for use compared to conventional security documents. However, one or more of the laminating films 21-27 may also be formed from other plastic materials, for example PET, PET-G, ABS or PVC.

[0190] Preferably, the laminate films 21 to 27 have a layer thickness of 30 μm to 400 μm, particularly 40 μm to 130 μm.

[0191] Thus, for example, the laminate films 21, 22, 23, 27 each consist of a polycarbonate film and have a layer thickness of 50 μm. The laminate films 24, 26 consist of a multi-layer plastic film and have a layer thickness of 150 μm. The laminate film 25 consists of a multi-layer laminate film and has a layer thickness of, for example, 350 μm. Furthermore, security features are provided, for example a transponder chip and / or an antenna integrated for contactless data communication.

[0192] Additionally, one or more of the laminate films 21-27 may be printed over a portion of their surface or may include an adhesion promoting layer on each surface to further improve interlayer adhesion to adjacent laminate films. Alternatively or additionally, each surface may be corona and / or plasma treated to improve interlayer adhesion.

[0193] The laminating films 22-27 and the laminate inlay 2 are applied to each other, for example in the order shown in Figure 1, and then laminated using heat and pressure to form the laminate 1. The laminating method used and the pressure and temperature used in the process are selected depending on the arrangement of the layers and the structure of the laminating films 21-27. Preferably, in the laminating method, the layers are inserted in the order shown in Figure 1 between two heated rollers of a roll laminator or between heated plates of a press, and heated at a pressure of, for example, 10 N / cm for polycarbonate (PC) to form the laminate 1. 2 ~400N / cm 2 , preferably 40N / cm 2 ~200N / cm 2 and temperatures in excess of 150° C., preferably 160° C. to 210° C. Other materials, such as PVC, may have settings that deviate from this.

[0194] The laminate inlay 2 is stacked and fed to the laminator so that the first partial region 31 containing the decorative ply and the radiation-curable adhesive layer are arranged between the laminating film 21 and the laminating film 22, as shown in Fig. 1. More preferably, in the second partial region 32, as shown in Fig. 1, no further layers are provided between the two laminating films 21, 22. During lamination, the opposing faces in the second partial region 32 come into contact with the laminating films 21, 22, the faces of the laminating films 21, 22 preferably melting together in the second partial region 32. Due to the melting of the laminating films 21, 22, the decorative ply or the decorative ply and the radiation-curable adhesive layer provided in the first partial region 31 sink further into the laminating films 21, 22 and are thus embedded in a monolithic body part, preferably made of polycarbonate. During this process, the at least one decorative ply is protected from degradation, particularly from excessive deformation, by the radiation curable adhesive layer.

[0195] This allows, as mentioned above, for multiple decorative layers to be inserted into at least one decorative ply, the decorative layers either having a low inherent stability or whose optical effects are particularly sensitive to the pressure and temperature loads of the lamination process.

[0196] In this embodiment, the area ratio of the one or more first partial regions 31 to the total area of ​​the one or more first and second partial regions 32 is preferably 80% or less, particularly 3% to 80%. NmIt is further advantageous to select the area ratio of the first partial region 31 to the second partial region 32 such that the surface tension exceeds 0.1 mm, preferably exceeds 5 Nm. This is measured in particular at a peel angle of 90°, a peel speed of 300 mm / min and a strip width of 10 mm. In this embodiment, the first and / or second partial region 31, 32 preferably has a width of 0.1 mm or more, in particular a width of 0.2 mm or more. It is further advantageous if the first partial region 31 and / or the second partial region 32 form a raster element of a raster which preferably comprises a plurality of raster elements, preferably more than 10, more preferably more than 20 raster elements.

[0197] The above method ensures that after lamination, a sufficient bonding bridge is formed between the laminating films 21, 22, preventing damage to the laminate 1 in daily use and hindering the protection of the laminate 1 against counterfeiting, and providing the laminate 1 with a decoration with good optical quality.

[0198] The laminate inlay 2 is also used as a cover ply in the laminate 1. Advantageously, the transfer ply is provided on the inside and protected by the first laminate film 21. Thus, the observer sees the transfer ply in a mirror-inverted state through the adhesive layer. Also, multiple transfer plies may be provided on different laminate films and at different distances from the face of the laminate. Similarly, multiple laminate plies may be applied on both sides of the first laminate film 21 in advantageous registration with respect to each other.

[0199] 2 shows a schematic diagram of a laminate inlay 2. The laminate inlay 2 comprises a laminate film 21, a radiation-curable adhesive layer 5 and a decorative ply 40. The decorative ply 40 is provided in one or more first partial regions 31 but is not provided in one or more second partial regions 32.

[0200] 2, the radiation-curable adhesive layer 5 preferably coincides with and extends coextensively with the decorative ply 40 in the first partial region 31. However, the radiation-curable adhesive layer 5 does not have to coincide completely with and extend coextensively with the decorative ply 40, but may be formed with an area slightly larger or smaller than that of the decorative ply 40. Thus, for example, the radiation-curable adhesive layer 5 may not completely fill the partial region 31, but may slightly protrude into the second partial region 32.

[0201] The decorative ply 40 provided in the first partial region 31 comprises at least one decorative layer and is peeled off (separated) from the carrier film of one or more different transfer films. In the embodiment shown in Fig. 2, the decorative ply 40 comprises a plurality of decorative layers 42, an adhesion-promoting layer 46, a protective layer 45 and an optional separation layer 44 or an adhesion-promoting layer and is peeled off from the transfer film 4 shown in Fig. 3.

[0202] The transfer film 4 comprises a carrier film 41 and a decorative ply 40. The decorative ply 40 comprises at least one decorative layer 42 and is peeled off from the carrier film. In the embodiment shown in Figures 2 and 3, the transfer film 4 further comprises optional further layers, namely one or more release layers 43, a separating layer 44 and / or an adhesion promoting layer, a protective layer 45 and an adhesion promoting layer 46. These layers may be omitted.

[0203] Preferably, the carrier film 41 consists of a plastic film, which preferably has a particularly low surface roughness, in particular a surface roughness of less than 0.5 μm, on the side oriented to the carrier ply. Preferably, the carrier film 41 consists of a PET film and has a layer thickness of, for example, 15 μm to 200 μm, for example 19 μm.

[0204] The release layer 43 preferably comprises a number of thin layers that reduce the peel force between the decorative ply 40 and the carrier film 41. In this embodiment, the release layer 43 has a thickness of, for example, 0.05 g / m 2 ~0.2g / m 2The release layer 43 consists of one or more wax layers with respective thicknesses of 0.5 g / m 2 ~1.5g / m 2 The release layer 44 is applied at an application weight of at least partially transferred with the decorative ply 40 as part of the decorative ply 40 and / or remains on the carrier film 41 and is peeled off with the carrier film 41.

[0205] The release layer 44 and / or adhesion promoting layer additionally support the separation of the decorative ply 40 from the carrier film 41 and / or support the subsequent overprinting of the transferred decorative ply 40 .

[0206] The protective layer 45 preferably comprises a varnish layer. 2 ~2.1g / m 2 weight per unit area and in particular includes one or more cross-linking moieties.

[0207] The decorative layer 42 preferably consists of one or more of the decorative layers mentioned above, which are applied at least partially or over the entire surface, and thus consist, for example, of an at least partially applied HRI layer, a metal layer, a varnish layer, a layer containing dyes and / or pigments, in particular optically variable pigments, a volume hologram layer, a conductive layer, a magnetic layer and / or a relief layer in which a surface relief is introduced.

[0208] In the embodiment shown in FIG. 3, for example, a relief layer is provided. In this relief layer, as shown in FIG. 3, a surface relief is formed. This surface relief consists of different relief structures in certain areas, for example different diffraction gratings or different types of relief structures. For example, a first area has a matte structure, in particular an anisotropic matte structure. A second area has a diffraction grating that mainly produces a first optically variable effect. A third area has a diffraction grating that produces a color-changing effect, for example as a zero-order diffraction structure when rotated. A fourth area has a relief structure that is formed as a blazed diffraction grating or a microlens array and produces an achromatic optically variable effect. Furthermore, as shown in FIG. 3, for example, an HRI layer and / or a metal layer is provided below this decorative layer as a further decorative layer. In this embodiment, the HRI layer and / or the metal layer is formed transparent, semi-transparent or opaque over the entire surface or over a part of the surface, and thus produces an optical effect when observed under reflected light and / or under transmitted light. Furthermore, above the relief layer there is provided a varnish layer as decorative layer 42 which comprises optically variable pigments in the form of dyes and / or pigments, in particular interference layer pigments, which is preferably not formed over the entire surface but is formed in a patterned manner in parts and which is of an opaque, semi-transparent or transparent nature, thus producing in each area a uniform or different optical effect when viewed under reflected or transmitted light.

[0209] The adhesion-promoting layer 46 is, for example, a primer layer having a density of 0.02 g / m 2 per unit area. 2 ~1.0g / m 2 is applied at the application weight.

[0210] As previously mentioned, the protective layer 45 and the adhesion promoting layer 46 may be omitted.

[0211] The decorative ply 40 has a surface 401 facing away from the carrier film 41 and a surface 402 facing the carrier film 41 .

[0212] To produce the laminate inlay 2 shown in Figure 2, a radiation curable adhesive is printed onto surface 211 of laminate film 21 and / or surface 401 of decorative ply 40 of transfer film 4. In this manner, radiation curable adhesive is applied to surface 211 of laminate film 21 and / or surface 401 of decorative ply, respectively, in one or more first regions to form radiation curable adhesive layer 5 in one or more first regions. In contrast, radiation curable adhesive is not applied to surface 401 of decorative ply 40 and / or surface 211 of laminate film 21 in one or more second regions.

[0213] The transfer film 4 is then applied to the surface 211 of the laminate film 21. At least one partial area of ​​the one or more first areas to which the radiation-curable adhesive layer 5 is not applied is provided between the surface 401 of the decorative ply 40 and the surface 211 of the laminate film 21 in at least one partial area of ​​the one or more first areas comprising the radiation-curable adhesive layer 5. Then, preferably, at least partial curing of the radiation-curable adhesive layer 5 occurs. This improves the adhesion between the transfer film 4 and the laminate film 21 in the first areas comprising the radiation-curable adhesive layer 5. The transfer film 4 is then peeled off from the laminate film 21. In the one or more first partial areas 31, the decorative ply is peeled off from the carrier film 41 when peeled off and remains on the laminate film 21. In the one or more second partial areas 32 of the laminate film, the decorative ply remains on the carrier film 41 and is peeled off together with the carrier film 41.

[0214] During peeling, the decorative ply 40 breaks at the boundary region between the first and second regions due to the different adhesive properties of the decorative ply 40 in the region of the first and second regions, which, as previously described, produces the effect that the first region and the first partial region 31 and the second region and the second partial region 32 are substantially coincident, although slight deviations may occur due to the path of the broken edges at the boundary.

[0215] The above method will be described in detail with reference to Figures 4 to 10b. Figure 4 shows the manufacturing steps for manufacturing the laminate inlay 2 and a manufacturing device 6 for this purpose.

[0216] The manufacturing apparatus 6 shown in Fig. 4 has a feeding device 61 and a feeding device 62. The feeding device has the transfer film 4 or the laminating film 21 wound around a supply roll, and a driving device and / or a control device that feeds the transfer film 4 or the laminating film 21 from the supply roll.

[0217] 5 shows a cross section of the laminate film 21 fed by the feeding device 62. The laminate film 21 has two surfaces 211 and 212 as shown in FIG.

[0218] The laminate film 21 is preferably a film formed from a thermoplastic plastic, and preferably contains polycarbonate (PC) as a main component. For example, the laminate film 21 is made of a polycarbonate film having a thickness of 30 μm to 400 μm, preferably 40 μm to 130 μm.

[0219] The laminating film 21 preferably has at least one surface which allows for sufficiently good printing quality of the UV-curable adhesive and which allows for good bonding to the decorative ply of the transfer film 4 upon curing of the UV-curable adhesive and good bonding to further laminating films during subsequent lamination.

[0220] In this context, a sufficiently good print quality means in particular that lines are printed uninterrupted with a width of up to 0.2 mm, preferably up to 0.1 mm. This allows text to be produced with a font size of up to 1 point, in particular up to 2 point. Furthermore, surface areas and lines must be printed in a covering manner without creating openings or double edges (squashed edges, in particular in the case of flexographic printing) or smudged edges.

[0221] It has been found that in order to achieve good printing quality, it is essential to set the surface roughness of the laminate film to a corresponding purpose, and for this reason it has been found to be advantageous to select the surface roughness such that the laminate film 21 has a surface roughness Ra of less than 2 μm, and even more preferably less than 0.8 μm.

[0222] 60 according to ISO2813 ° or more Below corner It has been found to be even more advantageous to select a surface having a gloss level of 98 or higher on a gloss scale. The laminating film 21 is fed to the printing device 63 by a web guide device (not shown). As previously mentioned, the surface 211 is preferably optimized to achieve good print quality.

[0223] Furthermore, one or more further machining stations may be provided before the transfer to the printing device 63. These are, for example, machining stations which further improve the surface quality of the face 211 for subsequent machining processes. Thus, for example, rolling and / or annealing devices, cleaning devices, for example cleaning brushes with compressed air support, surface treatment devices carrying out surface treatment by corona treatment and / or plasma treatment, which optimize the surface quality, in particular the surface roughness, may be provided. Furthermore, further printing devices, transfer devices etc. may be provided which apply additional registration marks or decorative elements to the faces 211 and / or 212 of the laminate film 21.

[0224] The printing device 63 is preferably a flexographic printing device, but it may also be a gravure printing device or a screen printing device, or it may also be a digital printing device, for example an inkjet printing device.

[0225] The printing of radiation curable adhesive onto the laminate film 21 in a printing device 63 is shown in Figures 6a and 6b.

[0226] Figure 6a shows a schematic cross section of the laminating film 21 and a printing roller of a printing device 63. A radiation curable adhesive is printed by the printing device 63 on a surface 211 of the laminating film 21. Figure 6b shows a schematic top surface of the laminating film 21 on which the radiation curable adhesive has been printed by the printing device 63.

[0227] As shown in Figures 6a and 6b, a radiation curable adhesive is applied to the surface 211 of the laminate film 21 in one or more first regions 51, but not to the surface 211 of the laminate film 21 in one or more second regions 52. Preferably, the first regions 51 comprise a pattern, letter, number, code or symbol or other graphic and / or alphanumeric and / or coded motif and are surrounded by one or more second regions 52, as shown in Figures 6c, 6b.

[0228] As mentioned above, the total surface area, i.e. the area ratio of the first area 51 to the first and second areas 52, is preferably selected to be equal to or less than 80%. Furthermore, the dimensions of the first area 51 and / or the second area 52 and their arrangement and shaping relative to each other are preferably formed relative to the first and / or second partial areas 31, 32 in order to form the laminate 1 while realizing the corresponding advantages after lamination of the laminate inlay 2, as mentioned above.

[0229] Adhesives that are cured by ultraviolet radiation sources or e-beam (electron beam) are preferably used as radiation curable adhesives. These adhesives preferably contain reactive acrylates, epoxies or enol ethers and photoinitiators. During exposure to light, the photoinitiators form radicals or reactive cations (super acids) that induce polymerization or crosslinking reactions of long chain molecules. Adhesive components are, for example, monoacrylates, diacrylates, triacrylates, oligomers and monomers.

[0230] Additionally, adhesives containing photoinitiators that react at different wavelengths may be used as radiation curable adhesives, so that multiple successive curing steps will result in the adhesive curing as desired.

[0231] It is preferable to use a radiation curing adhesive in which the crosslinking reaction begins at a wavelength of 250 nm to 420 nm, preferably at a wavelength of 350 nm to 400 nm.

[0232] For example, an adhesive having the following components is used as a radiation curable adhesive: Urethane acrylate oligomer 40% Acrylate Monofunctional 2(2-ethoxyethoxy)ethyl acrylate / (EOEOEA) 10% Acrylate Difunctional Ethoxylated (5) Hedanediol Diacrylate / (HD(5EO)DA 15% Aliphatic urethane acrylate oligomer 20% Propoxylated trimethylolpropane triacrylate 10% Initiator 5%

[0233] For application by flexographic printing, preferably the UV-curable adhesive is printed with a dynamic viscosity of 400 mPas to 2000 mPas, preferably 500 mPas to 1200 mPas.

[0234] This results in good print quality.

[0235] Furthermore, the printing device 63 may have a curing device for pre-curing the UV-curable adhesive during or immediately after printing. For this purpose, it has been found to be beneficial to carry out a pre-curing of more than 50%, preferably more than 80%, of the adhesive and / or to increase the dynamic viscosity of the radiation-curable adhesive by pre-curing to 20 mPas to 3000 mPas, preferably 50 mPas to 1000 mPas. By these measures, the printing quality can be further significantly improved or the stability of the radiation-curable adhesive when feeding the transfer film can be improved.

[0236] In addition to using flexographic printing, the radiation curable adhesive may be printed by gravure printing, screen printing or digital printing or a combination of these printing methods.

[0237] In the case of gravure printing, the desired design is copied onto a gravure roller. The radiation-curable adhesive is then printed onto the laminating film 21 using a gravure roller that corresponds to the known gravure printing. In the case of gravure printing, the viscosity of the radiation-curable adhesive is preferably selected to be less than 1000 mPas. Even in this case, as mentioned above, a combination with a pre-curing device is beneficial in order to prevent as much as possible smearing and smearing of the radiation-curable adhesive in the subsequent steps.

[0238] Furthermore, printing radiation curable adhesives by inkjet printheads is also advantageous, as compared to printing methods using fixed printing blocks, allowing individual real-time design, and the use of a pre-curing device is beneficial.

[0239] Additionally, printing device 63 may include a combination of different printing tools, such as screen printing tools and / or flexographic printing tools and / or inkjet printing mechanisms.

[0240] The transfer film 4 is unwound by a unwinding device 61 and is first fed to an optional surface processing device 65 via a web guiding device (not shown).

[0241] The transfer film 4 may be constructed, for example, as shown in Figures 7a and 7b. The transfer film 4 comprises a decorative ply 40 consisting of a carrier film 41, an optional release layer 44 and one or more decorative layers 42.

[0242] The decorative ply 40 has a surface 401 opposite the carrier film 41 and a surface 402 facing the carrier film 41 .

[0243] The decorative layer 42 is formed as described with reference to Figures 2 and 3. Preferably, the decorative ply 40 comprises one or more decorative layer 42 has differently shaped areas 421, 422, 433. FIG. 7b shows the top surface of the transfer film 4 having three areas 421, 422, 433, which may be decorated with one or more layer 42 are formed differently, so that different optical relief structures are introduced into one decorative layer 42 in the regions 421, 422, 433, which, for example, when tilted and / or rotated, result in different optically variable appearances, for example different color changes.

[0244] The optional surface treatment device 65 comprises, for example, a device for improving the surface quality of the face 401 of the decorative ply 40 by corona and / or plasma treatment. Furthermore, in addition to or instead of the surface treatment device 65, the aforementioned machining station may be provided for pre-treatment of the laminate film 21.

[0245] Optionally, the adhesive layer 5 may be printed on the transfer film 4, or on both the laminate film and the transfer film 4. The two adhesive layers may be different, similar or identical in composition and / or application weight.

[0246] The laminating film 21 and the transfer film 4 are then fed to a laminating device 64 via a web guide device (not shown). The laminating device 64 consists of, for example, two rollers. These rollers bring the radiation-curable adhesive layer 5 printed on the surface 211 of the laminating film 21 into contact with the surface 401 of the decorative ply 40 of the transfer film 4 through the gap between the rollers.

[0247] This is shown in figures 8a, 8b. Figure 8a shows diagrammatically in cross section two rollers of a laminating device 64 which bring the laminating film 21 and the transfer film 4 into contact. A radiation-curable adhesive layer 5 is arranged between the laminating film 21 and the decorative ply 40. It is advantageous to select the contact pressure so as to wet the face 401 of the decorative ply 40 and the face 211 of the laminating film 21 in the region of the first zone 51. Preferably, the contact pressure of the laminating device 64 is set so as to avoid smearing of the radiation-curable adhesive layer during the lamination process. For this purpose, a contact pressure of the laminating device 64 of 0.05 N / cm 2 ~100N / cm 2 , more preferably 1 N / cm 2 ~10N / cm 2 It is advantageous to select it so that

[0248] Furthermore, the application of the transfer film 4 to the laminating film 21 is preferably controlled by a registration device, which preferably comprises an adjustment means for adjusting the distance or tension of the laminating film 21 and / or the transfer film 4. By means of the adjustment means and position data of the adhesive overprint, the laminating film 21 and / or the transfer film 4, detected for example by an optical sensor, the positions of the laminating film 21 with the radiation-curable adhesive layer 5 and the transfer film 4 with the differently formed decorative areas relative to each other are adjusted such that the assigned areas of the adhesive overprint and the transfer film 4 are applied to each other in register with each other by the laminating device 64.

[0249] As a further option for registered transfer, the peripheral speed of the printing tool, e.g. the printing roller or printing screen, relative to the moving speed of the transfer film 4 or the laminating film 21 may be modified. This modification, known as tracking, may be between -10 per mille and +10 per mille, preferably between -5 per mille and +5 per mille, of the moving speed of the transfer film 4 or the laminating film 21. This tracking is particularly preferably performed by inkjet by controlling the timing of the ink ejection, i.e. by delaying or accelerating the timing. Also an extension / adaptation of the distance of the transfer film 4 or the laminating film 21 and tracking of the printing mechanism may be used.

[0250] If the transfer film 4 is not supplied as a single web, but rather as a number of webs in separate spaced apart webs, the relative positions of the multiple webs are detected and synchronised by suitable means as previously described.

[0251] This is shown, for example, in Fig. 8b, which shows the top side of the transfer film 4 after it has been laminated to the laminating film 21 by the laminating device 64. As shown, the areas 421, 422, 423 of the decorative ply 40 overlap the correspondingly assigned first areas 51. The transfer film 4 has different decorative layers in the areas 421, 422, 423, and the first areas 51 are provided with a radiation-curable adhesive layer. Thus, for example, the dot-shaped first areas 51 overlap the assigned areas 423, the cross-shaped first areas 51 overlap the assigned areas 422, and the letter-shaped first areas 51 overlap the assigned areas 421.

[0252] To achieve this registration, registration marks are preferably applied, e.g. as overprints, apertures (perforations), when overprinting the radiation-curable adhesive by means of the printing device 63. Corresponding registration marks are preferably applied to or are already provided on the transfer film 4. In the alternative, registration may also be performed when acquiring a corresponding image of the radiation-curable adhesive layer 5 or the laminating film 21 or the decorative elements of the transfer film 4.

[0253] The layered structure of the transfer film 4 and the laminating film 21 is then sent to a curing device 65 .

[0254] Preferably, the curing device 65 is a UV emitter or an e-beam emitter. For example, 50 mJ / cm 2 It is advantageous to use mercury lamps so that a UV dose of more than 1000 nm is generated. This is in particular a radiation doped with iron or gallium. Furthermore, UV-LED emitters can be used. Furthermore, it is also possible not to irradiate over the entire width of the material web, but to irradiate selectively in the predefined areas provided with the radiation-curable adhesive layer 5. This can be achieved, for example, by the use of a corresponding mask or by corresponding activation, for example, of a UV-emitter matrix.

[0255] 9 shows the corresponding irradiation of the layer structure by the curing device 65. Thus, for example, the layer structure consisting of the carrier film 41, the optional release layer 44, the decorative ply 40, the radiation-curable adhesive layer 5 and the laminating film 21 is irradiated from the side of the carrier film 41 by the irradiation source of the curing device 65. Moreover, irradiation can also be performed from the other side or the curing device 65 can be provided with multiple irradiation sources on both sides of the layer structure shown in FIG.

[0256] Furthermore, if the radiation-curable adhesive layer 5 already ensures a sufficient adhesion difference in the first and second areas 51, 52 in its current state, the curing device 65 may be omitted.

[0257] The layer structure is then Place Separation equipment Place , preferably consisting of a pair of rollers and / or air blast pieces and / or a deflector including a separation blade and / or a knife blade, or a combination thereof, which enables the transfer film 4 to be peeled off from the laminate film 21 under controlled conditions.

[0258] During peeling, due to the difference in interlayer adhesion between the first area 51 containing the radiation-curable adhesive layer 5 and the second area 52 not containing the radiation-curable adhesive layer 5 between the decorative ply 40 and the laminate film 21, the decorative ply 40 is peeled off from the carrier film 41 in the first partial region 31 during peeling and remains on the laminate film 21, while the decorative ply 40 and the carrier film 41 remain in the second partial region 32 and are peeled off together with the carrier film 41.

[0259] This is shown in figures 10a and 10b. Figure 10a shows a cross section of the layer structure after peeling. The layer structure of radiation-curable adhesive layer 5 and decorative ply 40 is provided in a first partial area 31 on face 211 of laminate film 21. This layer structure forms laminate inlay 2 which is wound onto a supply roll of winding device 67. As a remaining part of the peeled-off transfer film 4, decorative ply 40 still remains in the second partial area 32. This remaining part of the transfer film is fed to winding device 66 where it is wound onto a supply roll. Optionally, this remaining part may be reused in order to use as much of the decorative ply 40 as possible.

[0260] Figure 10b shows the top side of the laminate inlay 2. By means of the above-mentioned precisely registered application of the transfer film 4 to the radiation-curable adhesive layer 5, different motifs are generated in the first partial areas 31 of the laminate inlay 2, each producing an optically variable effect.

[0261] The method illustrated in Figure 4 is a roll-to-roll machining process, preferably proceeding at a speed between 0 m / min and 80 m / min, preferably between 15 m / min and 45 m / min, however, as an alternative embodiment, the method may be carried out in a sheet manner where individual sheets are printed, laminated, cured and peeled correspondingly.

[0262] The laminate inlay 2 produced according to the method of FIG. 4 may then be further processed by sheet-based methods. For this purpose, the width of the laminate film 21 corresponds at least to the width of the sheet format used in this example or to the width of a multiple of this sheet format. Furthermore, the laminate film 21 may have a wider width for the transfer process and the edges may be cut to the desired width in a subsequent machining process. A wider width has the advantage that the subsequent cutting results in a clean edge and allows the printing tolerances to be corrected relative to the edge of the web. However, this is moot for logistical reasons when the width of the web is readily available or standard. Furthermore, a transport track must be provided and removed depending on the design of the factory for the normal movement of the laminate film 21. Also, position or registration marks and other items of information, control tracks, etc. must be applied to the laminate film 21 and then cut.

[0263] Furthermore, an adhesive layer may additionally be printed on the laminating film 21 to improve adhesion for lamination with plastic films made, for example, from PET, PET-G, ABS and PVC. This printing may be done on one or both sides and may take place before printing the radiation-curable adhesive and / or before peeling off the transfer film. Roll-to-roll and sheet-based methods may likewise be used during lamination of the laminate inlay 2 with further laminating films to form a stack. Here too, it is advantageous to provide a corresponding registration of the films laminated to one another.

[0264] In this embodiment, the laminate inlay 2 may have the same format width as the laminate film to be laminated. Furthermore, the laminate inlay 2 may be supplied in a number of individual rolls, each having a width equal to the width of an individual document, for example. In another embodiment, the width of the film roll carrying the laminate inlay 2 is slightly larger than the laminate film to be laminated, in order to cover lateral tolerances during supply or to leave space for registration marks or other technical tracks, if necessary.

[0265] In the case of individual feed tracks, it is particularly advantageous if the individual rolls are guided in register with one another both transversely and along the direction of travel.

[0266] The laminate inlay 2 may also be cut to a corresponding size, e.g. for sheet processing, and finished before lamination with further laminate films. To this end, the laminate inlay 2 may be cut, e.g., into a sheet format or into narrower webs, in order to adapt the width of the film to the width of a belt laminator used for lamination of further laminate films. For lamination, the laminate inlay 2 is laminated with one or more laminate films to form a laminate packet corresponding to the desired security document. After lamination, the desired document format is punched out of the combined plate and further processed, e.g. for personalization.

[0267] The further material to be laminated consists, for example, of a carrier made of polyester, which is coated with a heat-seal adhesive. For the polyester carrier and the heat-seal adhesive, the usual thickness is between 25 μm and 200 μm. The decorative ply is applied to the surface of the adhesive layer. After application, the further adhesive layer is provided with an at least partial overcoat, so that in the subsequent lamination process a bond to the document substrate is achieved in the area of ​​the decorative ply. Such a structure is particularly suitable for preventing manipulation. Such laminating films are used, for example, for sealing paper-based documents on one or both sides in roll laminators.

[0268] Furthermore, the process shown in FIG. 4 may be repeated several times with different transfer films 4 or not only one but several transfer films 4 may be brought into contact with the laminating film 21 simultaneously or sequentially in the process shown in FIG. 4. Furthermore, different radiation curable adhesives may be used or dyed radiation curable adhesives may be used. Furthermore, the applied decorative plies 40 may be applied to the same side of the laminating film 21 or to different sides of the laminating film. Advantageously, the applied decorative plies 40 on different transfer films and / or radiation curable adhesive layers are arranged in register with respect to each other. This is achieved by the registration of the corresponding printing processes and / or the registration of the transfer films with respect to each other, as described above.

[0269] Furthermore, additional decorative layers may be printed, preferably in register, onto the laminate film 21 and / or the decorative ply 40 by a further printing mechanism and / or transferred by a stamping process, such as hot stamping.

[0270] 11 to 13 show a number of laminates 1 which are security documents formed with corresponding laminate inlays 2. Each of Figs. 11 to 13 shows a laminate 1 having a layer structure corresponding to the laminate shown in Fig. 1.

[0271] In the case of the laminate 1 shown in FIG. 11, the first partial region 31 is formed in the form of a raster with raster elements shaped as continuous letters (continuous letters "UTO"). A decorative ply 40 applied to this laminate consists of a diffractive structure. This diffractive structure comprises an HRI layer and as further security elements applied as a layer structure has a background over the entire surface, a passport photo 35 and information items 33, 34 formed by personalization with a laser.
