Description

Multi-layer body and method for producing a multi-layer body

The invention relates to a multi-layer body and a method for producing a multi-layer body.

It is known to provide cards, such as ID cards, with security features and to individualize them, for example with the name of the

Cardholder.

Foils, from which card blanks are made, mostly consist entirely of polyvinyl chloride (PVC), which is then made using

Surface application can be provided with security features. However, the disadvantage here is that the applied security feature lies on the surface of the card and can thus be damaged by mechanical and chemical influences. A further disadvantage here is that the films tend to be drifted and warped in the area of the applied security features. Even with a subsequent lamination, this often creates matt areas within the layers of the security features.

Alternatively, it is also known to use card blanks made entirely of polycarbonate (PC), it being possible for a security feature to be incorporated into the composite layer of the polycarbonate layers. It is true that PC cards of this kind typically hardly have any due to the mechanically more stable polycarbonate layers

Drifts and delays. However, it is disadvantageous that such card blanks made of polycarbonate on the one hand, especially in comparison to the above-mentioned Polyvinyl chloride cards, are significantly more expensive and in particular by means of the

Typically common manufacturing processes for polyvinyl chloride cards cannot be easily processed.

It is therefore an object of the present invention to provide an improved

Multi-layer body and an improved method for its manufacture

indicate which in particular avoids the disadvantages of the prior art.

The object is achieved by a method for producing a

Multi-layer body, in particular a laminate body, preferably one

Security document, preferably a composite card, which comprises the following steps, preferably in any order:

Step a) providing a first outer layer which comprises polyvinyl chloride and is transparent, in particular that which is visible to the human eye

Wavelength range is transparent.

Step b) providing a second outer layer which comprises polyvinyl chloride and is transparent, in particular that which is visible to the human eye

Wavelength range is transparent.

Step c) providing one or more intermediate layers, wherein the one or more intermediate layers between the first outer layer and the second

Outer layer are arranged and wherein at least one intermediate layer of the one or more intermediate layers comprises polycarbonate.

Step d) connecting, in particular laminating, the one or more

Intermediate layers, the first outer layer and the second outer layer.

Step d) is carried out in particular according to steps a), b) and c). The object is further achieved by a multi-layer body, in particular a laminate body, preferably a security document, preferably a composite card, the multi-layer body, which is produced in particular using a method according to one of claims 1 to 34, which has the following layers:

A first outer layer and a second outer layer, the first outer layer and the second outer layer being transparent, in particular being transparent in the wavelength range visible to the human eye, and wherein the first outer layer and the second outer layer comprise polyvinyl chloride.

One or more intermediate layers, wherein the one or more intermediate layers are arranged between the first outer layer and the second outer layer and wherein at least one intermediate layer of the one or more intermediate layers

Includes polycarbonate.

This has shown that the method for producing a

Multi-layer body and the multi-layer body makes it possible to combine the advantages of cards consisting entirely of PC and cards consisting entirely of PVC. In particular, since the manufacturing processes are identical or similar to the manufacturing of cards made entirely of PVC, it enables card manufacturers to utilize the advantages of PC cards without having to switch to PC processes. This can maintain productivity, since the process cycle for PVC cards is typically shorter than for PC cards. Furthermore, material and / or energy costs can be saved, in particular in comparison with cards consisting entirely of PCs. This enables a particularly cost-effective manufacturing process that is more environmentally friendly in terms of the energy resources used. In particular, the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate improves the mechanical stability of the multilayer body, so that, for example, applied security elements which have an optically variable element appear particularly brilliant. The multilayer body is preferably a composite card. A composite card is in particular a card in which at least two plastics, preferably at least two plastics with different softening temperatures, are combined, preferably connected.

The multilayer body preferably forms a security document, for example a bank card, a passport, a SIM card, an identity card, an ID card, or in particular a laminate for decorative applications, for example for use in the packaging sector and / or in

Automotive sector. The multi-layer body can represent an intermediate product and can also be further processed by means of further process steps, for example selected from deep-drawing, trimming, injection molding, overmolding, flooding, extrusion or combinations thereof.

Under polyvinyl chloride (PVC) comprising or polycarbonate (PC) comprising is preferably to be understood that a PVC layer or PC layer is provided over part or all of the area in a corresponding layer and / or that a layer of a corresponding layer is provided over part or all of the area is provided with a PVC coating. It is also possible that a layer comprising PVC or PC is a PVC layer or PC layer. A PC layer is preferably made entirely of PC and a PVC layer is preferably made entirely of PVC. It is possible, for example, that the first outer layer and the second outer layer comprising PVC are, for example, films made of PVC. At least one

Interlayer which is one or more intermediate layers comprising PC

for example a film made of PC and / or a PC sheet. It is also possible for at least one PVC layer to be applied over part of or over the entire area against a PC layer by means of co-extrusion.

Laminating is preferably understood to mean a method in which two or more plies and / or layers are produced by using heat and pressure are connected to one another, one or more plies and / or layers being melted at least in some areas at their layer boundary and thus one or more of the layers are melted together at least in some areas. During lamination, the foils are preferably heated to a temperature of more than 80 ° C. and at the same time pressed together by means of pressure. The temperature required for lamination depends on the materials used and is, for example, significantly lower with polyvinyl chloride than with polycarbonate. If different materials are to be connected to one another, additional layers and / or layers can serve as an adhesive layer, for example thermoplastic polyurethane.

A multi-layer body and / or a laminate body is understood to mean, in particular, a body which has a layer composite of two or more films and / or layers which are connected to one another by lamination, in particular connected to form a monolithic block, for example fused and / or glued are.

A “layer” and / or “layer” should be understood to mean a preferably essentially flat structure which itself can in turn consist of several layers. It can be, for example, a film or a circuit board. Alternatively, however, there are also more complex three-dimensional ones

Geometries possible.

Such a layer and / or layer does not necessarily have to represent an independent component, for example a functional layer can also be formed by printing on a substrate.

Transparent is preferably to be understood as meaning a degree of transmission in the range from 50% to 99%. Next is under semitransparent in particular one

Degree of transmission in the range from 30% to 50% and under opaque preferably a degree of transmission in the range from 0% to 30%. The specified transmission properties can preferably be determined at least after the connection, in particular lamination, of the first outer layer, the second outer layer and the one or more intermediate layers in step d).

The term “transmittance” is preferably understood to mean a measure which the transmitted portion of the transmitted light penetrates through areas of the multilayer body, in particular through areas of the first and / or second outer layer and / or one or more of the one or more intermediate layers

electromagnetic waves or the penetrating light, in particular the penetrating infrared light and / or the penetrating UV light. In particular, degrees of transmission can be in different

Wavelength ranges each be different. Preferably the

Determines the transmittance of the one or more intermediate layers in the wavelength range of the light visible to the naked human eye. In other words, the degree of transmission is determined in particular in the wavelength range visible to the human eye. The transmittance can

be high in the visible light range, for example, in one

Wavelength range of the IR or UV radiation, for example, but at the same time be lower.

Among the wavelength range visible to the human eye and / or the range of visible light, preference is given in particular to that which is visible to the human eye without the aid of optical aids and / or work equipment

Understood wavelength range.

Advantageous configurations of the invention are specified in the subclaims.

Advantageously, at least one intermediate layer is the one or more

Interlayers are opaque, especially those that are visible to the human eye

Wavelength range opaque. It is therefore useful that when providing the one or more intermediate layers in step c) at least one intermediate layer of the one or more intermediate layers is opaque, in particular is opaque in the wavelength range visible to the human eye.

This preferably ensures that the multilayer body for one

The viewer appears opaque, although the first and second outer layers are transparent. It is thus also possible, for example, to apply elements, in particular one or more functional layers, between the first and / or second outer layer, which are or should only be visible on one side. Another advantage here is that the security against forgery is increased, for example, by making it more difficult to determine information about the structure of such an element, in particular such a functional position, through an examination and / or observation from the rear.

One or more functional layers of the one or more functional layers have, for example, a printing layer, in particular a multi-layered one

Transfer layer and / or in particular multi-layer transfer layer of an applied transfer film, in particular a multi-layer lamination layer of an applied label or an applied film patch, a KINEGRAM®, a hologram, optically variable pigments, a magnetic strip, elements with an electrical and / or electronic function, in particular a sensor element , an RFID element, preferably with at least one chip, an antenna and / or a chip with contact areas.

A back or rear side is preferably a lower side, one of the first

In this case, the sequence is preferably specified starting from a view perpendicular to a plane spanned by the first, second and / or third intermediate layer in the direction from the first outer layer to the second outer layer. Thus, providing the one or more intermediate layers in step c) expediently comprises at least one of the following steps:

Step e) providing a first intermediate layer of the one or more

Intermediate layers. Here, the first intermediate layer is arranged in particular between the first outer layer and the second outer layer and preferably comprises polyvinyl chloride and / or polycarbonate.

The provision of the one or more intermediate layers in step c) expediently comprises the following step: Step h) providing one or more further intermediate layers of the one or more intermediate layers, which are arranged in particular between the first, the second and / or the third intermediate layer and the first outer layer and / or the second outer layer, and / or which in particular are polyvinyl chloride and / or or polycarbonate.

The second intermediate layer preferably comprises polycarbonate, in particular wherein the first intermediate layer and / or the third intermediate layer comprise polyvinyl chloride. It is therefore expedient that when providing the second intermediate layer in step f) the second intermediate layer comprises polycarbonate, in particular wherein when providing the first intermediate layer in step e) the first intermediate layer comprises polyvinyl chloride and / or when providing the third intermediate layer in step g) the third intermediate layer comprises polyvinyl chloride.

It is also possible that the second intermediate layer comprises polyvinyl chloride, in particular wherein the first intermediate layer and / or the third intermediate layer comprise polycarbonate. It is therefore expedient that when providing the second intermediate layer in step f) the second intermediate layer comprises polyvinyl chloride, in particular wherein when providing the first intermediate layer in step e) the first intermediate layer comprises polycarbonate and / or when providing the third intermediate layer in step g) the third intermediate layer comprises polycarbonate.

An interface is preferably formed between the first outer layer, the second outer layer, one or more intermediate layers of the one or more intermediate layers, in particular the first, second and / or third intermediate layer of the one or more intermediate layers and / or one or more intermediate layers of the one or more further intermediate layers, and / or one or more Functional layers of the one or more functional layers and the first outer layer, the second outer layer, one or more intermediate layers of the one or more intermediate layers, in particular the first, second and / or third intermediate layer of the one or more intermediate layers and / or one or more intermediate layers of the one or more intermediate layers several further intermediate layers, and / or one or more

In particular, it is possible that at least two intermediate layers of the one or more intermediate layers and / or the one or more further intermediate layers comprise polycarbonate and, during the connection, in particular lamination, the one or more intermediate layers, the first outer layer and the second outer layer in step d) be connected to one another via an adhesive, in particular via the first adhesive layer, and / or via one or more intermediate layers of the one or more intermediate layers which comprise polyvinyl chloride.

In particular, this means in other words that preferably not two

Intermediate layers comprising polycarbonate should be directly adjacent to one another, since there is preferably no adequate bond, in particular none, during lamination

cohesive bond made of polycarbonate layers. Therefore, layers comprising polycarbonate preferably alternate with layers comprising polyvinyl chloride and / or adhesive layers, in particular in order to achieve a stable bond.

For example, with the following layer structure, one of the sequences PVC / PVC / PC / PVC / PVC and / or PVC / PC / PVC / PC / PVC / PC / PVC of the plastics polycarbonate (PC) and polyvinyl chloride (PVC) is conceivable:

- first outer layer comprising PVC, - optionally a first intermediate layer of the one or more further intermediate layers comprising PC,

- optional first intermediate layer comprising PVC,

- second intermediate layer comprising PC,

- optional third intermediate layer comprising PVC,

- optionally a second intermediate layer of the one or more further intermediate layers comprising PC,

- second outer layer comprising PVC.

The sequence PVC / PC / PVC of the plastics polycarbonate (PC) and polyvinyl chloride (PVC) with the following layer structure is preferably possible:

- first outer layer comprising PVC,

- At least one intermediate layer of the one or more intermediate layers comprising PC, in particular the first intermediate layer comprising PC and / or the second intermediate layer comprising PC,

- second outer layer comprising PVC.

In addition, for example, with the following layer structure, the sequence PVC / PVC / PC / PVC / PC / PVC / PVC of the plastics polycarbonate (PC) and

- first intermediate layer comprising PC,

- second intermediate layer comprising PVC,

- third intermediate layer comprising PC,

- optionally a second intermediate layer of the one or more further intermediate layers comprising PVC,

- second outer layer comprising PVC. The sequence PVC / PC / PVC / PC / PVC of the plastics polycarbonate (PC) and polyvinyl chloride (PVC) with the following layer structure is preferred:

- first outer layer comprising PVC,

- first intermediate layer comprising PC,

- second intermediate layer comprising PVC,

- third intermediate layer comprising PC,

- second outer layer comprising PVC.

In particular, it is possible that the second intermediate layer is multilayered, preferably that the second intermediate layer has several layers of PVC, so that a sequence is also conceivable, such as PVC / PC / PVC / PVC / PC / PVC and / or PVC / PC / PVC / PVC / PVC / PC / PVC.

With regard to the transmission properties, preferably in the wavelength range visible to the human eye, the sequences with the following structure are particularly conceivable:

- transparent first outer layer

- optionally a transparent first intermediate layer of the one or more further intermediate layers

- optional transparent first intermediate layer

- Opaque second intermediate layer, which is preferably printed

- optional transparent third intermediate layer

- optionally a transparent second intermediate layer of the one or more

further intermediate layers

With regard to the transparency and / or the sequence of the plastic materials, a symmetrical sequence is particularly preferred, with regard to the second one Intermediate layer and / or a contact area of the first and third intermediate layer, possible. However, an asymmetrical sequence described as an example as follows is also possible:

- first intermediate layer comprising PC,

- second intermediate layer comprising PVC, which is preferably printed,

- Second outer layer comprising PVC, and / or

- transparent first outer layer,

- transparent first intermediate layer,

- opaque second intermediate layer, which is preferably printed,

- transparent second outer layer.

The advantage of a symmetrical sequence of the plastic materials has been found in particular that the multilayer body has a small amount of warpage and good flatness, in particular good flatness of one or more functional layers of the one or more functional layers. For example, a high level of register accuracy, in particular one or more intermediate layers of the one or more intermediate layers, can be achieved in this way, thereby increasing the security against forgery.

Register or register or register accuracy or register accuracy is preferably to be understood as a positional accuracy of two or more plies and / or layers.

The register accuracy should move within a specified tolerance and be as low as possible. At the same time is the register accuracy of several layers and / or layers to one another is an important feature in order to increase process reliability.

The precise positioning takes place in particular by means of markings, in particular by means of sensor marks, preferably optically detectable registration marks or register marks. These markings, in particular registration marks or register marks, preferably represent either special separate elements or areas or layers and / or layers or are preferably themselves part of the elements or areas or layers and / or layers to be positioned.

These are preferably applied to the first outer layer, to the second outer layer and / or to one or more intermediate layers of the one or more intermediate layers, in particular applied to the first, second, third intermediate layer and / or to the one or more further intermediate layers, particularly preferred on the at least one intermediate layer of the one or more

Intermediate layers comprising polycarbonate applied. The one or more functional layers are preferably not used here to determine the above-mentioned sequence of plastic materials and / or the transmission property or are not taken into account in the above-mentioned sequences. Thus, the advantages of the above-mentioned sequences also apply in the case of an overall asymmetrical sequence of materials, if the materials of the functional layers are also taken into account.

The one or more functional layers preferably form at least one

Security feature. It is therefore expedient for the one or more functional layers provided to form at least one security feature. A

It is particularly advantageous here if one or more functional layers of the one or more functional layers require process conditions that can be met by layers made of polycarbonate, but not by others Plastic layers, such as layers of polyvinyl chloride. That's the way it is

In particular, it is possible that one or more functional layers of the one or more functional layers, which preferably form at least one security feature, can be embedded between at least two layers which comprise polyvinyl chloride, in particular by inserting them before connecting the first

Interface between two plies and / or layers of the one or more

Functional layers of the one or more functional layers, which are preferably connected to the corresponding outer and / or intermediate layers.

In this case it is possible, for example, for the multilayer body to comprise two or more functional layers, in particular with a first and / or a second

Fixing clip or by means of an adhesive tape to the bracket of a tensile testing machine. A right angle is preferred between the peeled off layers attached to the tensile testing machine and the layers not

peeled layers produced. In particular, a right angle is produced between the first outer layer and the second outer layer. The lower part of the card, in particular the second outer layer, is expediently optionally fixed on a stabilizing plate. During the tensile measurement, the detached film layer, for example at least the corresponding intermediate layer with the

corresponding functional layer and the second outer layer, guided over a role. The peel strength is preferably recorded graphically and then evaluated, the first and last 5 mm of the measurement preferably not being taken into account. The results are given in N / 10 mm, for example.

It is also possible for the measurement to be carried out at points without a functional layer, for example in order to measure the adhesive force between a layer comprising polycarbonate and a layer comprising polyvinyl chloride.

A preferred embodiment with regard to the quality of the KINEGRAM® is to arrange a functional layer comprising polycarbonate on the inside, preferably on the inside with respect to the first and / or second outer layer. It is advantageously possible here for one or more functional layers of the one or more functional layers to form a KINEGRAM®, the KINEGRAM® being applied to the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate.

It is further possible that the first outer layer and / or the second outer layer and / or one or more intermediate layers of the one or more intermediate layers, in particular the first intermediate layer, the second intermediate layer, the third

The processing is preferably carried out by means of a laser, preferably by means of a neodymium-doped yttrium-aluminum-garnet laser and / or by means of a laser in the wavelength range from 946 nm to 1444 nm, in particular with a wavelength of 1064 nm. This makes it possible for the first outer layer, the second outer layer and / or one or more intermediate layers of the one or more intermediate layers,

Intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers, comprise one or more lasered layers.

For this purpose it is expedient that the first outer layer and / or the second outer layer and / or one or more intermediate layers of the one or more intermediate layers, in particular the first intermediate layer, the second intermediate layer, the third

Machining tool are processed, in particular individualized, the processing being carried out in particular by means of a laser, preferably by means of a neodymium-doped yttrium-aluminum-garnet laser and / or with a laser wavelength in the wavelength range from 946 nm to 1444 nm, in particular with one wavelength of 1064 nm.

Individualized is also to be understood as meaning, for example, personalized.

Expediently, the first outer layer and / or the second outer layer and / or one or more intermediate layers of the one or more intermediate layers, in particular the first intermediate layer, the second intermediate layer, the third

Intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers, provided with at least one laserable layer, this laserable layer preferably being and / or being provided with doping.

Doping is preferably to be understood as the introduction of foreign atoms into a layer, here in particular into the polycarbonate layer, in order to absorb the specific laser radiation, this preferably leading to a heat input into the material. A different gray level value is expediently achieved as a function of the laser dose. In particular, the processing by means of a laser is carried out after the joining, in particular lamination, of the one or more intermediate layers of the first

Outer layer and the second outer layer carried out in step d).

Processing is preferably carried out by means of a laser through one or more functional layers of the one or more functional layers and / or in precise register with one or more functional layers of the one or more functional layers, preferably so that in the first outer layer, the second outer layer and / or in one or more Intermediate layers of the one or more intermediate layers, in particular the first, second and / or third intermediate layers and / or one or more

Intermediate layers of the one or more additional intermediate layers, a lasered partial area is generated. This lasered sub-area is preferably generated in register over, under and / or adjacent to one or more functional layers of the one or more functional layers, preferably when viewed perpendicular to a plane spanned by the respective functional layer and / or the lasered sub-area, in particular with a viewing direction of the first outer layer in the direction of the second outer layer.

It is possible that the first outer layer and / or the second outer layer and / or one or more intermediate layers of the one or more intermediate layers,

in particular the first and / or second and / or third intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers have a lasered sub-area, this lasered sub-area in register above, below and / or adjacent to one or more functional layers of the one or a plurality of functional layers is arranged, preferably when viewed perpendicular to a plane spanned by the respective functional layer and / or the lasered partial area, in particular with a viewing direction from the first outer layer towards the second outer layer. The lasered partial area is preferably designed in the form of a pattern. It is also possible to generate a grayscale image in the lasered partial area, in particular by means of a halftone screen generated by means of a laser. A grayscale image can be

advantageously produce on one or more intermediate layers of the one or more intermediate layers, in particular the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate, with particularly high quality resolution and / or a particularly large number of gray levels. This is particularly compared with an image which is generated by lasering a layer comprising polyvinyl chloride.

A “grayscale image” is preferably to be understood here as an image which assigns the respective color value to the respective image points of the motif in the form of a corresponding gray value or brightness value of the assigned color channel. These gray values or brightness values can in particular also be generated in each case by a fine rasterization of binary raster points, the raster points preferably giving the human eye the impression of

Generate gray values or brightness values. A grayscale image is preferably easy to grasp by a human and / or machine viewer. It is conceivable, for example, to shape the portrait of an owner of a security document on the security document.

This preferably increases the security against forgery, in particular if functional layers which are precisely arranged in register form at least one security feature in relation to the lasered partial area.

It is possible here that the first outer layer and / or the second outer layer and / or one or more intermediate layers of the one or more intermediate layers, in particular the first intermediate layer, the second intermediate layer, the third

Intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers that are visible to the human eye

Wavelength range, in the UV range and / or in the IR range, in particular in the Range from 9400 nm to 10600 nm and / or in the wavelength range from 946 nm to 1444 nm, preferably at a wavelength of 1064 nm, are partially and / or fully opaque, semitransparent or transparent and / or are provided and / or after connecting, especially lamination, in step d).

A lasable layer is preferably at least partially opaque in the laser wavelength range, for example in the wavelength range from 946 nm to 1444 nm, preferably at a wavelength of 1064 nm, with layers arranged above and / or below the laserable layer being transparent in the range of the respective laser wavelengths are.

The UV range is understood here to mean in particular the range with wavelengths from 10 nm to 400 nm. The IR range is understood here to mean in particular the range with wavelengths from 800 nm to 1 mm.

It is thus possible that the multi-layer body and / or the first, second outer layer and one or more intermediate layers provided for producing the multi-layer body, in particular when viewed perpendicularly to one of the

Multi-layer body spanned plane, is opaque to the human eye in the composite and is internal, in particular with respect to the first and / or second

The outer layer is on the inside and is opaque in the wavelength range of the neodymium-doped yttrium-aluminum-garnet laser. As a result, a core that can be processed by means of a neodymium-doped yttrium-aluminum-garnet laser is advantageously arranged in the multilayer body, which is thus later individualized on the front and / or back, for example.

It is also possible that the lasable layer is opaque in the CO2 laser wavelength range, so that with a CO2 laser, for example

Surface lettering and / or tactile effects on the surface of the

corresponding laserable location can be realized. There is thus the particular advantage that several functions can be fulfilled by the one or more intermediate layers, in particular the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate, such as opacity, in particular in the IR laser range, and / or

Customizability as well as mechanical and / or thermal resistance.

For example, other plastic layers, such as a layer comprising polyvinyl chloride, are less suitable. In particular, the representation of gray scale images by means of lasering in a laserable PC is more advantageous than by means of

Lasering in laserable PVC, as binary black and white images are generated in laserable PVC.

It is expediently also possible for further individualization and / or personalization to be carried out with the application of one or more functional layers of the one or more functional layers, in particular before and / or after processing using a processing tool.

It is also conceivable that further processing by means of a

Machining tool, for example by punching, are performed.

It is also conceivable that further processing of one or more layers of the multilayer body, for example surface treatments such as

Plasma treatments and / or corona treatments are carried out.

In particular, it is also possible for a previous lasering to be carried out before step d), in particular before steps a), b), c) and / or d), with markings, in particular registration marks, and / or

Lot numbers are introduced into the first and / or second outer layer and / or one or more intermediate layers of the one or more intermediate layers. It is also useful that a first layer is selected from: first outer layer, second outer layer, one or more intermediate layers of the one or more

Intermediate layers, in particular first, second or third intermediate layers and / or one or more intermediate layers of the one or more further intermediate layers, with a second layer selected from: first outer layer, second outer layer, one or more intermediate layers of the one or more intermediate layers, in particular first, second or the third intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers is connected by bringing the first layer into direct contact with the second layer in a contact area.

In this case, the first layer and / or the second layer is preferably provided over part of a functional area with one or more functional layers of the one or more functional layers, in particular printed with at least one lacquer layer. The bond between the first layer and the second layer, which is preferably produced during the connection, in particular lamination, in step d), preferably takes place via the contact area which has no functional area.

The contact area is preferably used as an adhesive bridge. It has proven advantageous here that the one or more functional layers of the one or more functional layers are applied in a pattern, in particular in a grid. It is therefore useful that the functional area has a pattern,

in particular a grid, forms. In particular, it has proven to be advantageous that the contact area, in particular the adhesive bridges, covers at least 20%, preferably 40%, of the surface area of the first layer and / or the second layer.

It is also possible that the method further comprises the following steps, in particular before and / or during step d):

Step m) providing a hinge, Step n) joining, in particular lamination, of the hinge and the first

Outer layer, the second outer layer and / or the one or more intermediate layers, in particular the first, second and / or third intermediate layer and / or one or more of the one or more further intermediate layers, the hinge preferably being between the first outer layer and the second outer layer, is particularly preferably arranged between the first intermediate layer and the third intermediate layer, and in particular wherein the hinge, preferably when viewed perpendicular to one of the one or more intermediate layers, in particular from the first, second and / or third intermediate layer, adjacent to a plane spanned or more intermediate layers of the one or more intermediate layers, in particular to the first, second and / or third intermediate layer, is arranged, wherein the

Connecting is preferably carried out in step d).

It is useful here that the hinge end with at least one layer

Fabric tape is provided, wherein the hinge is preferably coated with polyvinyl chloride and / or is, in particular so that when connecting, in particular when laminating, the hinge, the polyvinyl chloride directly with the adjacent

Layers and / or plies is connected, in particular is connected with a material bond.

It is possible here for the multilayer body to include a hinge, the hinge preferably between the first outer layer and the second outer layer, particularly preferably between the first intermediate layer and the third

Intermediate layer is arranged, and in particular wherein the hinge, preferably when viewed perpendicular to one of the one or more intermediate layers, in particular by the first, second and / or third intermediate layer, spanned plane, adjacent to one or more intermediate layers of the one or more intermediate layers, in particular to the first, second and / or third intermediate layer is arranged. It is advantageous here if the hinge and / or at least the surface of the hinge consists of polyvinyl chloride, in particular because it adheres well to the first and second outer layers and / or the one or more intermediate layers, in particular well to the first, second and / or third liner, sticks.

A hinge is preferably a part that connects the

Multi-layer body with further, preferably flat, body produces.

For example, the hinge is a part that connects the

Multi-layer body as a data page, preferably as a passport card of a passport booklet for the seam of the passport booklet, which in particular has a hardcover, and preferably produces it for the remaining pages of the passport booklet. In particular, the data page is sewn into the passport book using the "hinge", i.e.

preferably via a flexible narrow strip on the multilayer body or on the data side, the hinge as a connecting element and as a flexible one

The hinge is used in the seam area of the passport booklet. It is preferred to use textile, in particular textile woven or textile non-woven, and / or non-textile Hinges made of PVC and / or TPU (TPU = thermoplastic polyurethane) and / or TPE (TPE = thermoplastic elastomers), which are in particular formed over the entire surface and / or have openings.

Here it is possible, for example, for the hinge to be arranged adjacent to the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate and / or the second intermediate layer, the hinge and the first

Outer layer and / or first intermediate layer and / or hinge and second outer layer and / or third intermediate layer preferably at least partially overlap and / or are in direct contact. It is also possible that the hinge and the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate and / or hinge and the second intermediate layer are in direct contact and / or are not in direct contact. In particular, steps a), b), c), d), e), f), g), h), i), j), k), I), m) and / or n) and / or the processing is carried out by means of a processing tool in an inline process and / or a roll-to-roll process. In particular, this enables films made of polyvinyl chloride and films made of polycarbonate to be processed together in an inline process.

“Inline” preferably means that the steps are carried out in direct succession without intermediate storage and / or simultaneously. It is also conceivable that one or more steps of steps a), b), c), d), e), f), g), h), i), j), k), I), m) and / or n) take place “offline.” “Offline” preferably means that a step is carried out at a later point in time, for example at the consumer, with temporary storage. Advantages of inline processes are, for example, low thermal fluctuations in the setting process, lower warpage, lower thermal energy requirements, and higher
