The invention relates to a method for producing a composite article and to a composite article.

For production-integrated surface decoration of plastic parts, plastic films or lacquer layers which can be transferred from a carrier film are used. Such decorated plastic parts, for example, in automotive for automotive interior parts such as door strips, strips in instrument panels and

Center console covers, in the consumer electronics area for decorative strips

Televisions or telecommunications used for housing shells portable devices such as mobile phones. In the surface decoration of

When using IM D technology (IMD = In-Mold Decoration) or IML technology (IML = In-Mold Labeling), plastic parts are inserted into a tool mold and then back-injected with an initially flowable filling medium. The invention is now based on the task, an improved

Specify a manufacturing method for a composite article as well as a

to provide correspondingly improved composite articles. This object is achieved by a method for producing a composite article with the following steps: a) providing a tool mold comprising a first mold part and a second mold part, wherein the first mold part and / or the second mold part has at least one filling channel; b) arranging at least two insertion elements in such a way that at least one first insertion element of the at least two insertion elements at least partially rests against the inner wall of the first tool molding or on the inner wall of the second mold part, and that at least a second insert element of the at least two insertion elements at least partially on the the side facing away from the inner wall of the first mold part or side facing away from the inner wall of the second mold part of the at least one first insert element is arranged; c) closing the mold by merging the first mold part and the second mold part; and d) filling a filling medium through the filling channel such that the at least one second inserting element of the at least two inserting elements is pressed against the at least one first inserting element of the at least two inserting elements and the at least one first inserting element

Insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements thereby at least partially firmly connected. Furthermore, this object is achieved by a composite article, in particular produced by the method according to one of

Claims 1 to 21 solved, wherein the composite article comprises a carrier body of a filling medium and at least two insertion elements, wherein at least one first insertion element of the at least two insertion elements and at least one second insert element of the at least two insertion elements are arranged such that the at least one second insertion element of the at least two

Insertion elements between the at least one first insertion element of the at least two insertion elements and the Trägerköper is arranged, and wherein the first insert element of the at least two insertion elements and the second insert element of the at least two insertion elements are at least partially firmly connected.

It has been found that the composite article of the invention in a

Manufacturing step can be made. The composite article is a multilayer composite article comprising the at least two insert elements. The

Insertion elements can have different functionalities.

Typically, these insert elements are heterogeneous, i. they persist

For example, depending on the desired function of different materials. By means of the method according to the invention, it is possible to produce a composite article which has a multi-layered, heterogeneous construction, wherein the composite article may be composed of several different materials, which in turn may be of different size and thickness. As a result, various functionalities can be integrated in the composite article. Further, this is a stable composite of heterogeneous structure and at the same time often required accurate registration of these layers to each other, the

inventive method to find integration in a component achieved. Thus, for example, it is possible for an insert element, which is mounted on the outside of the composite article, to have a protective function

Environmental influences or mechanical stress on the surface. The insert element on the outside thus protects further insert elements of the composite article, which may for example contain conductor tracks. Next has have shown that sensitive by means of the method according to the invention

Insertion elements which, for example, optically active, in particular optically variable, layers, interconnects or metallizations, in one

Composite article can be encapsulated in a single manufacturing step. In this way, on the one hand, the resistances of multilayer composite articles produced in this way can be increased and, on the other hand, the production process is improved such that only one production step is required for molding the composite article in a method suitable for short cycle times, such as

For example, high-pressure injection molding, resin injection or low-pressure casting is needed. This enables a cost-efficient production of complex multilayer composite articles, in particular in comparison to alternative production methods. Thus, in the method according to the invention compared to known methods such as hot lamination, gluing or plastic welding, for example, the connection of a

Injection molded part made of thermoplastic material with precisely positioned

Conductor layers on a deviating from the filling medium carrier material and with a deviating from the size of the conductor layer further protective layer of a turn divergent plastic material optically high quality in a single, at the same time forming, forming and joining manufacturing step together. Known methods in each case have considerable limitations in this regard. Thus, lamination methods are limited to predominantly two-dimensional geometries with regard to the possible component shape. If the layers to be joined have different dimensions, lamination, for example in a plate laminator, leads to impairment of the optical surface quality. Plastic welding processes are not suitable for the full surface connection of larger components. Adhesive methods require the accurate application of liquid adhesive systems and separate application of the individual layers to a previously produced plastic semifinished product. If the too connecting layers have different dimensions, gluing due to the different applied to the plastic semi-finished thicknesses visible gradations are to be expected on the surface, ultimately a

Impairment of optical quality mean. In addition to the advantages already mentioned, the method according to the invention enables a variable design of the layer structure of the composite article. For example, the second

Insertion element of the at least two insertion elements may be applied in regions such that this second insertion element of the at least two

Insertion elements is completely encapsulated by the first insert element of the at least two insertion elements and the filling medium.

In this case, the term "firmly connected" means a permanent connection of two elements so that they no longer separate from one another when the composite article is used as intended at least two insert elements firmly connected when there is a mechanically resistant connection between these two insertion elements and the at least one first insertion element of the at least two insertion elements and / or the at least one second

Insertion element of the at least two insertion elements can not be separated from each other without being damaged.

The term "area" is understood to mean a defined area which is occupied by an insert element or a layer of an insert element, the area lying in a surface formed by the inner wall of a mold part the inner wall of the first tool molding or on the Inner wall of the second mold part is arranged, an area which occupies a defined area.

The term "filling medium" is understood to mean a substance, substance mixture or sequence of filled media which by filling in the tool is able to bring about the connection between the at least two insertion elements by introducing the essential part of the energy required for this purpose The filling medium may consist of a thermoplastic plastic, a thermosetting reaction resin system, an elastomer, their respective educts, initiators or a mixture thereof, and at the same time also form a firmly adhering connection to one or more of the at least two insert elements. that it is the filling medium to a

Injection molding material is, which is injected into the tool. It is also possible that the tool mold has further tool moldings. Thus, for example, the tool mold may comprise a third tool molding in addition to the first tool molding and the second tool molding. Thus, it is possible that the tool mold comprises two or more mold parts. Preferably, the mold is an injection mold and the first

Werkzeugformteii a first injection molded part and the second Werkzeugformteii a second injection molded part, wherein the first injection molded part and / or the second injection molded part has at least one injection channel.

Further advantageous embodiments of the invention are designated in the subclaims.

It has been proven that in step d) the at least one first insert element of the at least two insert elements and / or the at least one second insert element Insertion element of the at least two insertion elements at least partially firmly connected to the filling medium.

Preferably, in the step b), the at least one first insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements are arranged precisely to one another. The exact arrangement of each other can also be done in an upstream step. Possibilities of precise arrangement of at least two

Insertion elements to each other are described below.

As exact fit or accurate register, the relative positionally accurate position of the second insertion elements to each other understood. The exact position can thereby by means of optically detectable registration marks or register marks on the

Molded parts and / or on the insert elements or by

constructional conditions such as pins, mandrels, recesses, etc., take place on the tool mold parts and / or on the insert elements. As a result, the positionally accurate position of the insertion elements relative to each other and / or the positionally accurate position of the insertion elements can be adjusted to the mold parts.

Advantageously, in step b), the at least one first insertion element of the at least two insertion elements and the at least one second

Insertion element of the at least two insertion elements not connected. As a result, the at least two insertion elements can be arranged independently of one another flexibly and individually as needed in the tool mold.

Preferably, the at least two insertion elements, in particular the at least one first insertion element of the at least two insertion elements and the at least one second insert element of the at least two insertion elements, by means of a vacuum, a clamping system or a precursor system accurately arranged to each other and held in the mold. It is also possible that a tool shape with tabs, thorns or

Mold recesses in the first mold part and / or in the second mold part is provided, and that the at least two insert elements, in particular the at least one first insert element of the at least two insert elements and the at least one second insert element of the at least two insert elements, by means of tabs, thorns or Formausnehmungen in the first tool molding and / or in the second tool molding

It is also possible for the at least two insertion elements, in particular the at least one insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements, to be held by means of a pressure-sensitive pressure-sensitive adhesive and / or by means of electrostatic or physical adhesion and to be arranged precisely to one another , Pressure-sensitive adhesives are adhesives which adhere two elements together depending on the force exerted on the adhesive surface. The adhesion here is initially such that the at least two insert elements have at least the adhesion required for the method to each other, but as a rule not the necessary adhesion for the intended application to each other. It can also be provided that the adhesion between two or more of the at least two insertion elements is only temporary and a separation according to the method is possible, in which at least one of the separate at least two insertion elements remains undamaged. In this case, it is achieved that the at least two insert elements can be arranged precisely to one another prior to filling of the filling medium and can no longer move substantially against each other before filling, so that the exact arrangement required for the respective application is ensured.

Furthermore, it is possible for the at least one first insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements to be arranged simultaneously in the tool mold. Such a simultaneous arrangement of the at least two

Inlay elements can be achieved for example by a pressure-sensitive adhesive and / or electrostatic or physical adhesion. The at least two insertion elements adhere to each other in such a way that they can be arranged or introduced simultaneously. The adhesion is in this case such that the at least two insert elements have at least the adhesion required for the method to one another, but as a rule not yet have the adhesive force necessary for the intended application to one another. In particular, the adhesion is set here such that the at least two film elements can be separated again without damaging them. Furthermore, it is advantageous that the at least one first insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements on the inner wall of the first

Tool molding or registered on the inner wall of the second mold part or accurately positioned.

It is also possible for the at least one first insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements to be folded in such a way that the at least one first insertion element Insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements, a stack of two or more rows in a direction substantially perpendicular to one from one side of the inner wall of the first mold part or to one side of the inner wall of the second Forming mold formed part surface. This makes it possible, for example, that the at least one first

Insertion element and / or form the at least one second insert element at least once folded system. Furthermore, it is possible for the at least one first insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements to be folded such that the at least one first insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements Insert elements form a stack of n> 2 lines in a direction substantially perpendicular to a surface formed from one side of the inner wall of the first mold part or to a surface formed from one side of the inner wall of the second mold part, wherein the lines of n> 2 lines alternately from the at least a first

Insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements. This makes it possible, for example, that the at least one first insert element and the at least one second insert element form a folded system such that, for example, the at least one first insert element of the at least two insert elements is folded and forms a first and a third row of the stack and between the first and third rows of the stack in the second row of the stack, the at least one second insert element of the at least two

Insertion element of the at least two insertion elements is sealed. In particular, this sealing takes place by mechanical loading of the sealing insert elements by the adjacent tool mold parts lying thereon or pressing on them. This makes it possible, the at least one first insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements of the

Lead out tool shape. These lead-outs can be used, for example, to lead out electrical contacts, from an inserted semifinished product or for coupling light into a light-conducting structure. It is also advantageous if, in step a), a tool mold having at least one mold recess in the first tool molding and / or in the second tool molding is provided and in step b) the at least one first insert element of the at least two insert elements in the at least one Mold recess is inserted, that the at least one first insert element of the at least two insertion elements forms a planar surface with the inner wall of the first mold part and / or the inner wall of the second mold part. In this way, a composite article can be produced, which in the at least one first insert element of the at least two insertion elements formed area, having a non-planar surface. Furthermore, it is thereby possible that the at least one second insertion element of the at least two insertion elements at least partially on the upper surface of the

multilayer composite article is exposed and thus directly accessible.

According to a further exemplary embodiment of the invention, the at least one first insertion element arranged in step b) has the at least two

Insertion elements a structural layer and / or a structured surface profile on and in step d), the filling medium is filled in such a way that the

Structural layer and / or a structured surface profile of the at least one second insert element of the at least two insertion elements imprints a relief. This makes it possible, for example, to impart a surface profile of the at least one first insert element to the previously unstructured at least one second insert element. This reduces on the one hand the

Production costs, since the at least one second insert element not

Accordingly, a very precise embossing of the surface structure within the multilayer composite article must be achieved. In this way, the scrap can be further reduced since fewer process steps, in which a reject can occur, for example due to inaccurate embossing of an insert element, are required. Should such a multilayer composite article be produced by individual process steps by means of conventional methods, such as embossing techniques, further process steps would therefore be necessary. By contrast, in the case of the method according to the invention, for example, a work step with regard to the provision of embossing tools and, for example, a working step with regard to the exact joining of the insert elements after embossing are dispensed with. Thus, with the method according to the invention it is possible to have multilayer composite articles with three-dimensional surface structures in at least two insert elements simple and inexpensive to produce. In addition, in this highly flexible process, a change in the structure introduced at any time without adaptation of the

Moldings possible, it must be used only one insert element of the at least two insert elements with a corresponding structure layer. According to a further preferred embodiment, the at least one first insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements one

Radiation and / or thermally curable material is made. The structural layer can be made from a structural paint that is thermally or by electromagnetic radiation curing, drying or crosslinking. Furthermore, it is possible for the structural layer to consist of a replication lacquer layer,

for example, from a thermoplastic paint, in which by means of heat and pressure by the action of a stamping tool, a surface profile is molded. Further, it is also possible that the replication lacquer layer is formed by a UV-crosslinkable lacquer and the surface profile by means of UV replication in the

Replizierlackschicht is molded. The surface profile is through

Impact of an embossing tool on the uncured Replizierlackschicht molded and the Replizierlackschicht immediately during or after the

Impression hardened by irradiation with UV light.

This makes it possible, for example, that the at least one first insertion element of the at least two

Insertion elements and the at least one second insertion element of the at least two insertion elements at least partially on the surface of the

Insertion elements at least partially in the first region of the

at least one second insertion element of the at least two insertion elements is covered. This makes it possible for the at least one second insert element of the at least two insert elements to adapt to the shape of the at least one first insert element of the at least two insert elements. Such manufactured composite articles are particularly advantageous if they have contacts or sensors which should be accessible from the outside. Further, composite articles so made can have particular decorative three-dimensional surface effects.

Preferably, the parameters pressure and temperature in step d) during filling of the filling medium are selected such that the at least two

Insertion elements, in particular the at least one first insertion element of the at least two insertion elements and / or the at least one second

A further embodiment of the mold parts may additionally include that the optimum temperature profile for the method for producing a composite article is supported by a variothermal tempering option already integrated into the mold parts.

Furthermore, it is advantageous that the optimum temperature profile for the process is supported by a variable temperature control of the mold. It is also possible that the parameter time is predominantly due to

Material properties, temperature and mass ratios of the introduced insert elements and filling media and the tool temperature results, is additionally influenced by a variable temperature control of the tool. In Correlation of these parameters, the parameter time in step d) at

Filling the filling medium can be chosen such that the at least two insertion elements, in particular the at least one first insertion element of the at least two insertion elements and / or the at least one second

According to a further preferred embodiment, instead of a hardening substance or mixture of substances, the filling medium can consist of a gas or vapor-phase liquid, which is heated appropriately by preheating or compression. In this case, only the connection between the at least two insert elements is then produced, without any further connection with a filling medium.

It is possible that in step b) the at least one first insertion element of the at least two insertion elements and the at least one second insertion element of the at least two insertion elements consist of different materials. For example, it is possible that the at least one first insert element of the at least two insert elements or the at least one second insert element of the at least two insert elements made of thermoplastic PET

(= Polymethylmethacrylate), wherein the first mentioned material corresponds to the material of the adjacent to the filling medium layer and the second said material or material mixture corresponds to the material of the filling medium. It has been shown that such material pairings enable firm connections in the sense of the invention. Next, such material pairings are also suitable for the at least two insertion elements. Also, it is possible that

contiguous layers of the at least two insert elements of the same material such as PET, PP, ABS, or polyamide or a mixture of materials such as PET and PC exist. Adjacent layers of the at least two insert elements can also consist of different materials or material mixtures. Furthermore, it has proven to be advantageous for material pairings that intrinsically no solid compound within the meaning of the invention to each other to resort to adhesive or primer layers or a thermal, physical or chemical pretreatment, the use of the method a solid compound in terms of Invention enable. These coatings and / or pretreatments are preferably carried out on the at least one first insertion element of the at least two insertion elements and / or the at least one second insertion element of the at least two insertion elements and are selected such that at least in some areas a firm connection in the context of the invention can be produced.

Further, it is advantageous if the between filling medium and the at least one first insert element of the at least two

Inlay elements arranged insertion elements, in particular the at least one second insertion element of the at least two insertion elements are thinner than the first insertion element. In this way, an efficient heat transfer is made possible by the insertion medium between the filling medium and the at least one first insertion element of the at least two insertion elements to the at least one first insertion element of the at least two insertion elements. Furthermore, it is possible that one or more surfaces in the composite article of introduced one or more materials and / or the one or more of the at least two insert elements wholly or partly by thermal,

physical or chemical surface treatment are preprocessed. It is also possible for the filling medium filled in step d) to be supplemented or replaced by a preheated semifinished product. The filling medium is preferably a polymeric material, for example PP, PC, ABS, PBT (= polybutylene terephthalate), PMMA

(= Polymethyl methacrylate), PS (= polystyrene), PVC, TPU (= urethane-based thermoplastic elastomer), polyamide or polyolefin, or thermosetting reaction resin systems, in particular PUR, EP resins, PF resins or UP resins. Furthermore, it is advantageous, especially for functional integrations in the

Composite articles, when the filling medium is a mixture of different types of material, and / or the filling medium is already enriched with reinforcing materials, such as glass, carbon or natural fibers, which in turn may be in the form of short or long fibers, and / or fillers, such as, for example, copper, aluminum oxide or graphite, and / or additives, such as, for example, the coloring, laser penability, paintability,

Preferably, the thickness of the filling medium is 0.1 mm to 5 mm, preferably 0.5 mm to 2 mm.

Furthermore, it is advantageous that the at least one first insertion element of the at least two insertion elements and / or the at least one second

It is advantageous that in step b) the at least one first insert element of the at least two insert elements with at least one adhesive layer and / or the at least one second insert element of the at least two insert elements at least one adhesive layer is arranged, wherein the parameters pressure and temperature in the step d) during filling of the filling medium are selected such that the at least one adhesive layer at least partially with the at least one second insert element of the at least two insert elements and / or the at least one first insert element the at least two insert elements is firmly connected. This ensures that the at least one first

Insertion element of the at least two insertion elements with at least one

Adhesive layer and / or the at least one second insert element of the at least two insertion elements and / or the filling medium are at least partially firmly connected. This is particularly advantageous if the composite article to be produced has insert elements which comprise inorganic materials such as, for example, ceramics, glass or metals. This is also advantageous, for example, if extraneous layers, for example of the at least one second insert element of the at least two insert elements and of the filling medium adjoin one another, for example PET and polyamide or polyamide and polyolefin.

It is also possible that in step b) the at least one second

In this case, for example, it is possible that the tool molding 1 1 has elevations 71 in the areas in which, for example, the multi-layer insert element 2 does not have certain layers, whereby the multi-layer insert element 2 can be registered by means of the elevations 71. By means of the elevations 71, recesses 72 can thus be produced in the insert elements 2, 3 of the composite article 1 in a targeted manner. Furthermore, the elevations 71 allow accurate positioning of the insertion elements 2, 3. Depending on the shape, size, design and positioning of the elevations 71, different composite articles 1 can be produced. So can

For example, the surface of the composite article 1 by means of the shaping and the number and the distance of the elevations 71 are designed. 5d shows a composite article 1 which has a recess 72 in the region 47 in the filling medium 4 of the carrier body. Next, the composite article 1, the insert element 3 in the area 48. The insert element 3 is thus accessible via the recess 72. The composite article 1 of Fig. 5e has a recess 72 in the region 47 in the filling medium 4 of the carrier body and a recess 72 in the region 47 of

Insertion element 2 on. The insert element 3, which is present in the region 48, is thus accessible from two sides of the composite article 1. The composite article 1 of Fig. 5f has a recess 72 in the region 47 of the insert elements 2, 3 and the insert element 3 is thus present only in areas 49 and 50. 5g further shows a composite article 1 which has a recess 72 in the filling medium 4 of the carrier body and in the insert element 3 in the region 47. The filling medium 4 is thus present in the regions 51 and 52 and does not exist in the region 47.

FIGS. 6a to 6c show a method for producing a composite article 1. The method shown in FIGS. 6a to 6c corresponds to the method shown in FIGS. 3a to 3c and 1 a to 1e with the difference that that

Insertion element 2 has a structured surface profile. Further, as shown in Fig. 6a, the insert elements 2, 3 are inserted simultaneously. As shown in FIG. 6 a, the insert element 2 has recessed areas 54 and raised areas 53. The insert element 2 has, for example, a replication lacquer layer into which a structured surface profile is embossed by means of an embossing tool, for example a replication roller or an embossing punch. The structured surface profile has a structure depth between 2.5 pm and 1500 pm, preferably between 10 pm and 200 μm, more preferably between 15 pm and 65 pm. The structure depth is in this case the height distance between the raised areas 53 and the recessed areas 54, wherein the height distance is related to a direction perpendicular to the surface formed by the inner wall of the mold part 1 1. The replication lacquer layer has a thickness between 2.5 μm and 1500 μm, preferably between 10 μm and 200 μm, more preferably between 15 μm and 65 μm. If the texture depth is set smaller than the thickness of the replica varnish layer, the bottom of the recessed regions 54 is covered by the replication varnish layer. The replication lacquer layer consists for example of a thermoplastic lacquer in which the heat and pressure by the action of a stamping tool

Surface profile is molded. It is also possible that the

Replizierlackschicht is formed by a UV-crosslinkable paint and the

Surface profile is formed by means of UV replication in the Replizierlackschicht. In this case, the surface profile is formed by the action of an embossing tool in the uncured Replizierlackschicht and the Replizierlackschicht before and / or immediately during and / or after the impression by irradiation with UV light cured.

It is also possible for the replication lacquer layer to have a metallization at least in regions, for example a thin metal layer of gold, silver, chromium, copper or aluminum, in particular with a thickness between 0.5 nm and 50 nm.

As shown in FIG. 6 a, an insert element 3 is arranged on the side of the insert element 2 facing away from the inner wall of the tool molding 11.

With regard to the configuration of the insert element 3, reference is made here to the above statements.

As shown in Fig. 6b, after closing the mold 10 by

Merging the mold part and the mold part 12, the filling medium 4 filled through the filling channel and thus the mold 10 is filled with it. In this case, the insert element 3 is pressed against the insert element 2 in such a way that the insert element 3 is pressed into the recessed regions 54 of the insert element 2 until the insert element 3 makes contact in all regions

Insertion element 2 has. In this case, the insertion elements 2, 3 at least partially connected in certain areas. With regard to the filling of the filling medium 4, reference is made here to the above statements. Next, the filling medium 4 at least firmly connects to the insert element 3. The insert element 2, as shown in Fig. 6b, depending on the structured surface profile of the insert element 2 also has a structured surface profile.

After hardening of the filling medium 4 to a carrier body or after cooling of the filling medium 4, the mold 10 is opened and the composite article 1 is removed, as shown in Fig. 6c. The hardened carrier body including the insertion elements 2, 3 arranged thereon represents the

Composite article 1 ready.

In principle, the proportions may also be inversely proportional to the ratios shown in the figures, i. the part of the composite article created by the filling medium is smaller than the part of the inserting elements.

FIGS. 7a and 7b show schematic sectional views of insert elements 2, 3. Thus, FIG. 7a shows an insert element 2, 3, which has a carrier layer 20 and a

Structure layer 25 has. With regard to the layer 20, reference is made here to the above statements. The structural layer 25 here has areas 58 which deform under pressure and heat less or more than the remaining structural layer 25. Thus, it is possible that the structural layer 25 consists for example of a physically or chemically foamed material, wherein the areas 58, below Pressure and heat are less or more deformable. So the areas 58 of the

Structure layer 25 may be formed from a material that substantially withstands the parameters of pressure and temperature during filling of the filling medium 4 or is not compressible, so that the areas 58 act as a spacer between the rigid Innwandung the mold part 1 1 and the insert element 3. The areas 58 thus experience during filling of the filling medium 4 no or only a very small deformation. Furthermore, the structure layer 25 can be applied only in regions. The structural layer 25 preferably has a thickness of between 2.5 μm and 1500 μm, preferably between 10 μm and 200 μm, more preferably between 15 μm and 65 μm.

FIG. 7b shows an insert element 2, 3 which has a carrier layer 20 and a structural layer 25. With respect to the carrier layer 20 is here above

References. The structure layer 25 is here formed as a replication lacquer layer and has a structured surface profile, which is embossed, for example, by means of an embossing punch. With regard to the replication lacquer layer, reference is made here to the above statements.

Furthermore, it is possible to carry out the layer 25 of the insertion elements 2, 3 over the entire surface or in regions.
