Description

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 card holder.

Foils, from which card blanks are made, mostly consist entirely of polyvinyl chloride (PVC), which are then provided with security features by means of surface application. 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 curl and warp 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 such PC cards typically have hardly any curls or distortions due to the mechanically more stable polycarbonate layers. However, it is disadvantageous that such card blanks made of polycarbonate, on the one hand, are significantly more expensive, in particular compared to the above-mentioned polyvinyl chloride cards, and in particular cannot be easily processed by means of the typically widespread production method for polyvinyl chloride cards.

It is therefore the object of the present invention to provide an improved multilayer body and an improved method for its production which in particular avoids the disadvantages of the prior art.

• Schritt a) Bereitstellen einer ersten Außenlage, welche Polyvinylchlorid umfasst und transparent ist, insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich transparent ist.
• Schritt b) Bereitstellen einer zweiten Außenlage, welche Polyvinylchlorid umfasst und transparent ist, insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich transparent ist.
• Schritt c) Bereitstellen ein oder mehrerer Zwischenlagen, wobei die ein oder mehreren Zwischenlagen zwischen der ersten Außenlage und der zweiten Außenlage angeordnet werden und wobei zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen Polycarbonat umfasst.
• Schritt d) Verbinden, insbesondere Laminieren, der ein oder mehreren Zwischenlagen, der ersten Außenlage und der zweiten Außenlage.
• Schritt d) wird hierbei insbesondere nach den Schritten a), b) und c) durchgeführt. Die Aufgabe wird weiter gelöst durch einen Mehrschichtkörper, insbesondere Laminatkörper, vorzugsweise Sicherheitsdokument, bevorzugt Verbundkarte, wobei der Mehrschichtkörper, welcher insbesondere mit einem Verfahren nach einem der Ansprüche 1 bis 34 hergestellt ist, der die folgenden Lagen aufweist:
  • Eine erste Außenlage und eine zweite Außenlage, wobei die erste Außenlage und die zweite Außenlage transparent sind, insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich transparent sind, und wobei die erste Außenlage und die zweite Außenlage Polyvinylchlorid umfassen.
  • Ein oder mehrere Zwischenlagen, wobei die ein oder mehreren Zwischenlagen zwischen der ersten Außenlage und der zweiten Außenlage angeordnet sind und wobei zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen Polycarbonat umfasst.
  • Hierdurch hat sich gezeigt, dass durch das Verfahren zur Herstellung eines Mehrschichtkörpers sowie durch den Mehrschichtkörper es ermöglicht wird, die Vorteile von vollständig aus PC bestehenden Karten und vollständig aus PVC bestehenden Karten zu vereinen. Insbesondere, da die Herstellungsverfahren identisch oder ähnlich zur Herstellung von vollständig aus PVC bestehenden Karten sind, ermöglicht es Kartenherstellern die Vorteile der PC-Karten zu nutzen ohne auf PC-Prozesse umstellen zu müssen. Hierdurch kann die Produktivität erhalten werden, da typischerweise der Prozesszyklus bei PVC-Karten kürzer ist als bei PC-Karten. Weiter können Material- und/oder Energiekosten eingespart werden, insbesondere im Vergleich zu vollständig aus PC bestehenden Karten. Hierdurch ist ein besonders kostengünstiger und hinsichtlich der eingesetzten Energieressourcen umweltfreundlicherer Herstellungsprozess möglich. Insbesondere durch die zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen umfassend Polycarbonat wird die mechanische Stabilität des Mehrschichtkörpers verbessert, so dass beispielsweise applizierte Sicherheitselemente, welche ein optisch variables Element aufweisen besonders brillant erscheinen.
  • Der Mehrschichtkörper ist vorzugsweise eine Verbundkarte. Eine Verbundkarte ist insbesondere eine Karte, bei welcher mindestens zwei Kunststoffe, bevorzugt mindestens zwei Kunststoffe mit unterschiedlichen Erweichungstemperaturen, kombiniert werden, bevorzugt verbunden werden.
  • Der Mehrschichtkörper bildet vorzugsweise ein Sicherheitsdokument, beispielsweise eine Bankkarte, einen Reisepass, eine SIM-Karte, einen Personalausweis, eine ID-Karte, oder insbesondere auch ein Laminat für dekorative Anwendungen, beispielsweise zur Anwendung im Verpackungsbereich und/oder im Automobilbereich, aus. Der Mehrschichtkörper kann ein Zwischenprodukt darstellen und kann auch noch mittels weiterer Prozessschritte, beispielsweise ausgewählt aus Tiefziehen, Beschneiden, Hinterspritzen (Spritzguss), Übergießen, Überfluten, Extrudieren oder Kombinationen davon weiterverarbeitet werden.
  • Unter Polyvinylchlorid (PVC) umfassend bzw. Polycarbonat (PC) umfassend ist vorzugsweise zu verstehen, dass eine PVC-Schicht bzw. PC-Schicht teilflächig oder vollflächig in einer entsprechenden Lage vorgesehen ist und/oder dass eine Schicht einer entsprechenden Lage teilflächig oder vollflächig mit einer PVC-Beschichtung versehen ist. Es ist auch möglich, dass eine Lage umfassend PVC bzw. PC eine PVC-Schicht bzw. PC-Schicht ist. Hierbei besteht eine PC-Schicht vorzugsweise vollständig aus PC und eine PVC-Schicht vorzugsweise vollständig aus PVC. Es ist beispielsweise möglich, dass die erste Außenlage und die zweite Außenlage umfassend PVC beispielsweise Folien aus PVC sind. Die zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen umfassend PC ist beispielsweise eine Folie aus PC und/oder ein PC-Sheet. Es ist auch möglich, dass zumindest eine PVC-Schicht mittels Co-Extrusion teilflächig oder vollflächig gegen eine PC-Schicht aufgebracht wird.
  • Unter einem Laminieren wird vorzugsweise ein Verfahren verstanden, bei dem zwei oder mehrere Lagen und/oder Schichten durch Einsatz von Hitze und Druck miteinander verbunden werden, wobei hier ein oder mehrere Lagen und/oder Schichten zumindest bereichsweise an ihrer Schichtgrenze aufgeschmolzen werden und so ein oder mehrere der Schichten zumindest bereichsweise miteinander verschmolzen werden. Bei dem Laminieren werden hierbei die Folien vorzugsweise auf eine Temperatur von mehr als 80°C erwärmt und gleichzeitig mittels Druck aufeinandergepresst. Die bei dem Laminieren benötigte Temperatur ist abhängig von den eingesetzten Materialien und liegt beispielsweise bei Polyvinylchlorid deutlich tiefer als bei Polycarbonat. Sollen unterschiedliche Materialien miteinander verbunden werden, können zusätzliche Lagen und/oder Schichten als Klebeschicht dienen, wie beispielsweise thermoplastisches Polyurethan.
  • Unter einem Mehrschichtkörper und/oder einem Laminatkörper wird insbesondere ein Körper verstanden, welcher einen Schichtverbund aus zwei oder mehreren Folien und/oder Lagen aufweist, welche durch ein Laminieren miteinander verbunden sind, insbesondere zu einem monolithischen Block verbunden sind, beispielsweise verschmolzen und/oder verklebt sind.
  • Unter einer „Lage“ und/oder „Schicht“ soll dabei ein vorzugsweise im Wesentlichen flächiges Gebilde verstanden werden, welches selbst wiederum aus mehreren Schichten bestehen kann. Es kann sich dabei beispielsweise um eine Folie oder eine Platine handeln. Alternativ sind jedoch auch komplexere dreidimensionale Geometrien möglich.
  • Eine solche Lage und/oder Schicht muss dabei nicht notwendigerweise ein eigenständiges Bauteil darstellen, beispielsweise kann eine Funktionslage auch durch Drucken auf einen Untergrund gebildet werden.
  • Unter transparent ist vorzugsweise ein Transmissionsgrad im Bereich von 50% bis 99% zu verstehen. Weiter ist unter semitransparent insbesondere ein Transmissionsgrad im Bereich von 30% bis 50% und unter opak bevorzugt ein Transmissionsgrad im Bereich von 0% bis 30% zu verstehen.
  • Vorzugsweise lassen sich die angegeben Transmissionseigenschaften zumindest nach dem Verbinden, insbesondere Laminieren, der ersten Außenlage, der zweiten Außenlage und der ein oder mehreren Zwischenlagen in Schritt d) ermitteln.
  • Unter „Transmissionsgrad“ wird vorzugsweise ein Maß verstanden, welches den transmittierten Anteil der im Durchlicht durch Bereiche des Mehrschichtkörpers, insbesondere durch Bereiche der ersten und/oder zweiten Außenlage und/oder ein oder mehrerer der ein oder mehreren Zwischenlagen, hindurchdringenden elektromagnetischen Wellen oder des hindurchdringenden Lichts, insbesondere des hindurchdringenden infraroten Lichts und/oder des hindurchdringenden UV-Lichts, angibt. Insbesondere können Transmissionsgrade in unterschiedlichen Wellenlängenbereichen jeweils unterschiedlich sein. Vorzugsweise wird der Transmissionsgrad der ein oder mehreren Zwischenlagen im Wellenlängenbereich des für das unbewaffnete menschliche Auge sichtbaren Lichts bestimmt. In anderen Worten wird der Transmissionsgrad insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich bestimmt. Der Transmissionsgrad kann beispielsweise im Bereich des sichtbaren Lichts hoch sein, in einem Wellenlängenbereich der IR- oder UV-Strahlung, beispielsweise jedoch gleichzeitig geringer sein.
  • Bevorzugt wird unter dem für das menschliche Auge sichtbaren Wellenlängenbereich und/oder dem Bereich sichtbaren Lichts insbesondere der für das menschliche Auge ohne Zuhilfenahme von optischen Hilfs- und/oder Arbeitsmitteln sichtbare Wellenlängenbereich verstanden.
  • Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen bezeichnet.
  • Vorteilhafterweise ist zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen opak, insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich opak. Es ist also zweckmäßig, dass bei dem Bereitstellen der ein oder mehreren Zwischenlagen in Schritt c) zumindest eine Zwischenlage der ein oder mehreren Zwischenlagen opak ist, insbesondere im für das menschliche Auge sichtbaren Wellenlängenbereich opak ist.
  • Hierdurch wird vorzugsweise erreicht, dass der Mehrschichtkörper für einen Betrachter opak erscheint, obwohl die erste und zweite Außenlage transparent sind. Somit ist es beispielsweise auch möglich, zwischen der ersten und/oder zweiten Außenlage Elemente, insbesondere ein oder mehrere Funktionslagen, aufzubringen, welche lediglich einseitig sichtbar sind bzw. sein sollen. Ein Vorteil ist hierbei weiter, dass die Fälschungssicherheit erhöht wird, indem zum Beispiel erschwert wird, Informationen über den Aufbau eines solchen Elements, insbesondere einer solchen Funktionslage, durch eine rückseitige Untersuchung und/oder Betrachtung zu ermitteln.
  • Ein oder mehrere Funktionslagen der ein oder mehreren Funktionslagen weisen beispielsweise eine Druckschicht, eine insbesondere mehrschichtige Übertragungslage und/oder insbesondere mehrschichtige Transferlage einer applizierten Transferfolie, eine insbesondere mehrschichtige Laminationslage eines applizierten Etiketts oder eines applizierten Folienpatches, ein KINEGRAM®, ein Hologramm, optisch variable Pigmente, einen Magnetstreifen, Elemente mit einer elektrischen und/oder elektronischen Funktion, insbesondere ein Sensorelement, ein RFID-Element, bevorzugt mit zumindest einem Chip, einer Antenne und/oder einem Chip mit Kontaktflächen, auf. Eine Funktionslage kann beispielsweise funktionelle und/oder dekorative Zwecke erfüllen.
  • Unter einem Chip mit Kontaktflächen ist insbesondere ein Chip zu versehen, welcher über eine elektrische Verbindung kontaktierbar ist, bevorzugt mittels ein oder mehrerer Funktionslagen der ein oder mehreren Funktionslagen kontaktierbar ist und/oder mittels eines Leiters von außerhalb des Mehrschichtkörpers kontaktierbar ist.
  • Vorzugsweise folgt die Blickrichtung einer Flächennormalen der ersten Außenlage von der ersten Außenlage in Richtung der zweiten Außenlage. Dabei zeigt die Blickrichtung bevorzugt von oben nach unten und/oder von vorne nach hinten. Weiter ist eine Vorderseite vorzugsweise eine obere Seite, eine der ersten Außenlage zugewandte Seite und/oder eine der zweiten Außenlage abgewandte Seite. Eine Rückseite oder Hinterseite ist bevorzugt eine untere Seite, eine der ersten Außenlage abgewandte Seite und/oder eine der zweiten Außenlage zugewandte Seite.
  • Unter einer Seite ist insbesondere eine Oberfläche zu verstehen.
  • Vorzugsweise wird das Verbinden, insbesondere Laminieren, der ein oder mehreren Zwischenlagen, der ersten Außenlage und der zweiten Außenlage nach dem Bereitstellen der ein oder mehreren Zwischenlage, der ersten Außenlage und der zweiten Außenlage durchgeführt.
  • Die ein oder mehreren Zwischenlagen umfassen beispielsweise mindestens eine oder mehrere der folgenden Lagen: eine erste Zwischenlage, eine zweite Zwischenlage und/oder eine dritte Zwischenlage.
  • Hierbei umfassen die erste Zwischenlage, die zweite Zwischenlage und/oder die dritte Zwischenlage bevorzugt Polyvinylchlorid und/oder Polycarbonat und sind insbesondere zwischen der ersten Außenlage und der zweiten Außenlage angeordnet.
  • Weiter ist es möglich, dass die erste Zwischenlage, die zweite Zwischenlage und/oder die dritte Zwischenlage mit der folgenden Abfolge angeordnet sind: erste Zwischenlage, zweite Zwischenlage, dritte Zwischenlage. Hierbei wird die Abfolge vorzugsweise ausgehend von einer Betrachtung senkrecht auf eine von der ersten, zweiten und/oder dritten Zwischenlage aufgespannten Ebene in Richtung von der ersten Außenlage zur zweiten Außenlage angegeben.
  • Somit umfasst das Bereitstellen der ein oder mehreren Zwischenlagen in Schritt c) zweckmäßigerweise mindestens einen der folgenden Schritte:
• Schritt e) Bereitstellen einer ersten Zwischenlage der ein oder mehreren Zwischenlagen. Hierbei wird die erste Zwischenlage insbesondere zwischen der ersten Außenlage und der zweiten Außenlage angeordnet und umfasst vorzugsweise Polyvinylchlorid und/oder Polycarbonat.

  • 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 comprises polycarbonate.
  • This has shown that the method for producing a multi-layer body and the multi-layer body make it possible to combine the advantages of cards made entirely of PC and cards made 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. In this way, productivity can be maintained, 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, through the at least one intermediate layer of the one or more intermediate layers comprising polycarbonate the mechanical stability of the multilayer body is improved, 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 the automotive sector.

  • 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 surface in a corresponding layer and / or that a layer of a corresponding layer is provided over part of or over the entire surface 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, for the first outer layer and the second outer layer comprising PVC to be, for example, films made of PVC. The at least one intermediate layer of the one or more intermediate layers comprising PC is, 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 bonded to one another through the use of heat and pressure, one or more plies and / or layers being melted at least in some areas at their layer boundary and thus one or more layers and / or layers several of the layers are fused 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 that are connected to one another by lamination, in particular are 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, more complex three-dimensional geometries are also possible.

  • Transparent is preferably to be understood as meaning a degree of transmission in the range from 50% to 99%. Furthermore, under semitransparent is to be understood in particular a 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).

In particular, degrees of transmission can be in different Wavelength ranges each be different. The degree of transmission of the one or more intermediate layers is preferably determined in the wavelength range of the light that is visible to the unarmed human eye.

The transmittance can be high, for example, in the visible light range, but can be lower in a wavelength range of IR or UV radiation, for example at the same time.
  • The wavelength range visible to the human eye and / or the range of visible light is preferably understood to mean, in particular, the wavelength range visible to the human eye without the aid of optical auxiliary and / or work equipment.
  • Advantageous configurations of the invention are specified in the subclaims.
  • At least one intermediate layer of the one or more intermediate layers is advantageously opaque, in particular opaque in the wavelength range visible to the human eye. It is therefore expedient 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 appears opaque to a viewer, 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-layer transfer layer and / or in particular a multi-layer transfer layer of an applied transfer film, an in particular 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 surfaces.

  • It is also possible for the first intermediate layer, the second intermediate layer and / or the third intermediate layer to be arranged in the following sequence: first intermediate layer, second intermediate layer, third intermediate layer. 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 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.

What is achieved hereby in particular is that if an attempt is made to detach a functional layer, the functional layer is torn open. This is advantageous, for example, in the event that the functional position forms a security feature because this makes counterfeiting activities more difficult and thus, in particular, increases the counterfeit security.

An interface is preferably also an area which is arranged where an interface was arranged immediately before two layers were connected.

A peel test is preferably to be understood as a measurement method according to ISO / IEC 10373-1, Section 5.3. In particular, an optionally preconditioned card is cut into 10 mm wide test strips.

For example, all layers on one side of a functional layer are then removed, preferably with a length of 5 mm to 10 mm. For example, with a sharp knife, the layers above a security feature, in particular a KINEGRAM®, are peeled off from the core, ie in particular from an intermediate layer and the functional layer which forms the security feature, preferably the KINEGRAM®. Appropriately, the peeling takes place only partially.

The peeled end is then preferably fastened to the holder of a tensile testing machine using a fastening clip or by means of an adhesive tape. A right angle is preferably made between the peeled-off layers attached to the tensile testing machine and the non-peeled-off layers. 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, is preferably passed over a roller. 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 also 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 intermediate layer and / or one or more intermediate layers of the one or more intermediate layers several further intermediate layers are processed in a further step by means of a processing tool, in particular are individualized. 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 that the first outer layer, 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 Include intermediate layers, one or more lasered layers.

For this purpose, it is useful 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 intermediate layers several further intermediate layers are processed in a further step by means of a processing tool, 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 of 946 nm to 1444 nm, in particular with a wavelength of 1064 nm.

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

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, are expediently 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 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 precisely in 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 further intermediate layers, a lasered partial area is generated. This lasered sub-area is preferably created in register above, below 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 being arranged precisely above, below and / or adjacent to one or more functional layers of the one or more functional layers, preferably when viewed perpendicular to one of the respective functional layer and / or the lasered sub-area spanned plane, in particular with a viewing direction from the first outer layer in the direction of 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 advantageously be generated 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 a particularly high 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 fine rastering from binary raster points, the raster points preferably producing the impression of gray values or brightness values for the human eye. 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 intermediate layers several further intermediate layers in the wavelength range visible to the human eye, 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 nm, partially and / or fully opaque, semitransparent or transparent and / or provided and / or after joining, in particular 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 multilayer body and / or the first, second outer layer and one or more intermediate layers provided for the production of the multilayer body, in particular when viewed perpendicular to a plane spanned by the multilayer body, are opaque to the human eye as a composite and are on the inside, in particular with respect to the first and / or second outer layer lying on the inside, is opaque in the wavelength range of the neodymium-doped yttrium-aluminum-garnet laser. This is advantageously a by means of a neodymium-doped yttrium-aluminum-garnet laser machinable core arranged in the multi-layer body, which is thus later individualized on the front and / or back, for example.

It is also possible for the lasable layer to be opaque in the CO ₂ laser wavelength range, so that, for example, surface inscriptions and / or tactile effects on the surface of the corresponding laserable layer can be implemented with a CO ₂ laser.

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 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 greyscale images by means of lasering in a laserable PC is more advantageous than by means of lasing in laserable PVC, since binary black-and-white images are produced 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 is carried out by means of a processing tool, for example by punching.

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), whereby, for example, markings, in particular register marks, and / or lot numbers in the first and / or second outer layer and / or one or more intermediate layers of the one or more intermediate layers are introduced.

It is also expedient that a first 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 third intermediate layers and / or one or more intermediate layers of the one or more further intermediate layers 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 third intermediate layer and / or one or more intermediate layers of the one or more further intermediate layers, is connected by connecting the first layer is brought 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 expedient that the functional area forms a pattern, in particular a grid. 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.

A hinge is preferably a part which creates a connection between the multilayer body and further, preferably flat, bodies. For example, the hinge is a part that connects the multilayer body as a data page, preferably as a passport card of a passport booklet to the seam of the passport booklet, which in particular has a hardcover, and preferably connects it to 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 serving as a connecting element and as a flexible hinge in the seam area of the passport booklet.
