Description

USE OF A MULTIPLE LAYER WITH

AT LEAST ONE BIOPOLYMER AND / OR BIOPOLYMER

LAYER

The invention relates to the use of a multi-layer structure for an element for use as a floor, wall, ceiling, furniture, decoration, interior construction element, preferably strip, profile, edge, door and / or window element, Facade, wallpaper, car interior, car exterior and / or outdoor covering element.

Layered structures of the aforementioned type have plastics that are based on petroleum. Often such layered structures consist exclusively of petroleum-based plastics that are also not biodegradable, such as polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).

As a result, materials are used to create the layered structures that do not regrow and are usually not biodegradable. Particularly with regard to the scarcity of raw materials and the falling oil stocks, non-renewable raw materials are disadvantageous as basic materials for layered structures of the aforementioned type. Due to falling global oil stocks, long-term rising costs for petroleum-based materials are to be expected, which will consequently dramatically increase the production costs of the entire multilayered layer structure in the long term.

If the oil reserves were used up, a layer structure known from the prior art could no longer be produced economically.

Furthermore, the layer structures known from practice cannot be reused or biodegraded, which means that there is very little ecological compatibility. The petrochemical materials can also contain pollutants and are therefore not environmentally friendly.

The object of the present invention is now to avoid the aforementioned disadvantages in the prior art or at least to substantially reduce them. In particular, it is the object of the present invention to provide an ecologically sustainable, environmentally friendly, pollutant-free and / or biodegradable multi-layered layer structure To provide, which is also suitable and / or usable for large series production. The above object is achieved when using a multilayered layer structure for an element for use as a floor, wall, ceiling, furniture, decoration, interior construction element, preferably strip, profile, edge, door and / or window element, facade, wallpaper, car interior, car exterior and / or outdoor covering element according to the invention solved in that the multilayered layer structure has at least one biopolymer-containing and / or biopolymeric layer and at least one decorative layer.

According to the invention, an outdoor covering element is understood in particular to mean a facade, glass surface, terrace covering and / or privacy element.

According to the invention, the multilayered layer structure can also be used for an element for use as a household device, display, sign, picture, truck tarpaulin, body, sanitary object, lamp, electrical device, household article, clothing, jewelry, clock, lamp, carpet, switch, socket, awning , Curtain, roller shutter, blinds, packaging, mobile phone, cover for mobile phone and / or stove can be provided.

According to the invention, a biopolymer-containing material and / or a biopolymer is understood to be a biodegradable material and / or a biogenic raw material, in particular a material made from organic substances being preferred. The organic substances can be designed as plant-based and / or living substances and / or raw materials.

An advantage of a biopolymer is that it is preferably biodegradable and / or is obtained in particular from a renewable raw material. Conventional plastic materials are - as previously stated - mostly based on petroleum and consequently on a limited resource. This can be avoided by using a biopolymer, so that the multilayer film composite has a very high ecological compatibility.

The decorative layer, if appropriate in combination with the layer, can influence the optical appearance of the multilayered layer structure at least in regions. The decorative layer can consequently be opaque at least in some areas and / or represent a decor.

In a particularly preferred embodiment it is provided that the decorative layer is directly and / or indirectly with, in particular as a film layer trained, layer is connected. In the case of an indirect bond, provision is made for at least one further layer to be arranged between the decorative layer and the layer.

In particular, it is provided that a metal-containing and / or metallic metal layer is provided in the multilayer layer structure. The metal layer can be arranged indirectly and / or directly on the layer.

The layer is particularly preferably designed as a film layer. Alternatively or additionally, it can be provided that a film layer is integrated in the layer structure that is not designed as a layer - i.e. that has no biopolymer material.

When the invention came about, it was surprisingly found that metallic surfaces can be produced on a film layer with low production costs. Such a metallized film layer and / or layer and / or a metal layer which interacts at least indirectly with a film layer and / or layer can be applied to at least one of the aforementioned elements. In this way, metallic surfaces can be provided on different elements with comparatively low production costs. These metallic surfaces can also have a polished surface and are not limited to matt appearances.

According to the invention, the multilayered layer structure can be provided in the manner of a composite and / or finish film for lamination on furniture and / or interior fittings and / or floor panels. A finish film is preferably understood to mean the following:

The so-called finish film, which is known from furniture and interior design, is preferably a decorative, in particular optionally printed, film based on paper and / or plastic.

The finish film preferably has a ready-to-use surface layer and / or protective layer and can be used for further processing. In particular, the finish film can be used for furniture, floor and / or pa neel surfaces. In addition, the finish film can also be designed as a composite film, in particular where the finish film has a plurality of layers and / or film layers.

The finish film is preferably applied to carrier layers and / or plates, in particular those made of timber materials, in particular by lamination. Furthermore, the film layer can also be applied to on-site plates and / or substrates, in particular with an applied adhesive equipment being provided on the back.

Furthermore, it can realistically recreate the film surface in all types of real wood optically and sometimes also haptically. It is also possible to design new creations for surface structures.

This opens up a multitude of design options in the area of design, in which metallic surfaces can be used. The metallic surface can be visible over the entire surface or at least in a partial area due to the multi-layer structure. In a simple manner, the invention succeeds in providing elements with a metallic surface without having to apply the metal layer directly or directly to the elements. Invention according to the application of the metallic surface is carried out on one of the aforementioned elements by applying the multilayered layer structure.

In comparison to painting with metallic colors in particular, there are a number of advantages. In this way, a uniform appearance of the metal layer can be achieved, namely without streaks, cloud formation and / or clump formation. In addition, the optical appearance of the metal layer is not limited to certain metals or imitations of certain metals. According to the invention, the appearance of a large number of different metals can be ensured.

This creates a completely new design concept or a completely new possibility for the integration of metallic surfaces in different areas of the interior architecture, for example in the floor, wall and / or ceiling area. Thus, according to the invention, it can be provided with a floor covering element with a metallic surface, which has a metal layer with a comparatively small layer height, which has preferably been applied directly to the film layer and / or layer. According to the invention, it is therefore no longer necessary to lay metal plates for the (optical) production of a metallic floor. According to the invention, metal optics can consequently be provided genuinely and authentically in the form or in the form of a, in particular flexible, decorative film which is also economical to produce. In particular, the multi-layer structure according to the invention is distinguished by its high compatibility for further elements, preferably multi-layer modular and / or elastic floor coverings, furniture and / or interior finishing surfaces.

The aforementioned low manufacturing costs are based on the fact that a film layer with a very low procurement price can be used, which subsequently interacts at least indirectly with a metal layer, the metal layer being able to be distinguished by a very low material consumption.

Both shiny and brushed metal surfaces can be provided, in particular shiny chrome, shiny gold, shiny copper, shiny rose copper, natural aluminum, brushed chrome, brushed stainless steel, brushed gold and / or brushed copper.

Furthermore, according to the invention, the material used of the metal can be very resource-saving, since in particular very small layer thicknesses are sufficient to achieve a very good optical quality, as will be explained below.

Furthermore, the multi-layer structure is characterized by a very high light fastness, which has been increased or improved by up to 40% compared to a conventional plastic film. In addition, the multi-layer structure has very good temperature resistance, color consistency and water resistance. In this way, multilayered layer structures with a metal layer can be made available with different production batches with no or hardly visible optical deviations. Even when stored in the water for more than 24 hours, there are preferably no visible changes to the cut edges of the multi-layer structure, so that the multi-layer structure can be made watertight.

So far, it has been common, for example for floor coverings and / or furniture, each of which is a preferred application of the invention, to use a wood decor, since metallic surfaces can only be imitated with a very low color quality. According to the invention can consequently be used to imitate the wood an alternative can be provided, preferably for floor coverings, furniture and / or interior fittings. As a result, a unique metallic materiality can be achieved, whereby trend decorations with a high level of attractiveness can be provided. The metal character can be authentically reproduced, since the metal layer has "real" metal - and not just imitates the appearance of metal. Nonetheless, the multi-layer structure is environmentally friendly with minimal use of resources.

In a particularly preferred embodiment, it is provided that the film layer and / or the layer is at least partially transparent and / or translucent, in particular translucent. The transparency is an optical property of a material, in this case the film layer and / or the layer. According to the invention, a transparent design means such a design of the film layer and / or the layer that is permeable to electromagnetic waves. Electromagnetic waves can consequently be transmitted through the film layer, a high degree of transmission being provided, preferably a degree of transmission of greater than or equal to 0.9. According to the invention, the film layer is permeable to light from the spectrum of electromagnetic radiation (380 to 750 nm) that is visible to humans. The metal layer can be optically visible and / or recognizable through the film layer.

According to the invention, translucent means a partial light permeability of a body, in the present case the film layer. It is conceivable that a body is translucent, but not transparent, since it partially lets light through.

Accordingly, transparency is understood to mean image and / or gaze permeability, translucency being understood as translucency. The reciprocal property of translucency is opacity, which means that it is opaque. As a result, the film layer is not opaque, at least in some areas. A translucent film layer can in particular have a milky or whitish structure or appearance.

The film layer and / or the layer is preferably designed in such a way that the metal layer is optically visible and / or recognizable at least in regions on the use side of the multilayer layer structure. In this way, it can be achieved that the metallic surface is also recognizable from the outside - that is, on the user side. In principle, it is also conceivable that the measurement tall layer on both sides - that is, the user side and the side opposite to the user side - is visible. Consequently, this can be used in a targeted manner to change the appearance of the metal layer, for example by overlaying it with the at least partially transparent and / or translucent film layer and / or layer. Thus, according to the invention, the multilayered layer structure can have the metallic surface only in some areas and / or allow the metallic surface to show through over the entire surface, optionally overlaid by the appearance of the film layer and / or the layer. In particular, a large number of different optical design options for the multilayered layer structure can be achieved.

The transparent layers of the multilayer protective layer without the metal layer, in particular the top layer, are preferably provided in a crystal-clear embodiment so that the metallic effect comes into its own. However, it can also be provided that the aforementioned layers have a deliberately translucent coloring, for example a milky and / or whitish coloring. The metallic effect can also be influenced by this, for example a high-gloss chrome surface can have a milky, whitish tint to make it look more matt.

In addition, it is provided in a further embodiment of the inventive concept that the metal layer is directly and / or indirectly firmly connected to the film layer. A direct bond between the metal layer and the film layer is understood to mean a bond of this type in which the metal layer is arranged directly above and / or below the film layer. In the case of a medium bond between the metal layer and the film layer, further layers can also be enclosed between the metal layer and the film layer, the metal layer being firmly connected to the film layer via the further layers.

The multilayered layer structure preferably has a carrier layer at least in regions, the metal layer being arranged directly and / or indirectly on the carrier layer. The carrier layer is preferably designed as a biopolymer-containing and / or a biopolymer-containing layer.

The metal layer can in particular be firmly, preferably inseparably, connected to the carrier layer. In addition, the metal layer can be provided on the top side, facing the user side, and / or on the underside on the carrier layer. The carrier layer ultimately serves as a carrier for the metal layer and, moreover, the carrier layer can also be connected directly and / or indirectly firmly to the film layer.

In a further preferred embodiment, the film layer and / or the biopolymer-containing and / or biopolymeric layer is designed as a partial, preferably uninterrupted, layer and / or full-area layer.

The film layer is preferably designed as a carrier layer, so that the film layer is preferably also arranged directly on the carrier layer formed as a film layer, in particular has been applied to the film layer. An inseparable and / or non-destructive detachable composite of the film layer to the metal layer enables a compact arrangement of the multi-layer structure, which is also flexible and / or elastic in the manner of a decorative film due to the flexible and / or elastic properties of the film layer can. Accordingly, the multilayered layer structure can also be arranged on uneven surfaces of the element, and without air inclusions or folds of the multilayered layer structure being caused. It is further particularly preferred, in particular on the upper side, facing the user side, on the layer, film layer, the carrier layer, the decorative layer and / or the metal layer, at least in regions, that at least one at least one-layer protective layer is arranged. Preferably, the protective layer is a layer according to the invention - i.e. a biopolymer-containing and / or biopolymeric layer.

The protective layer can be formed as a protective film and / or as a protective coating, in particular as a coating, impregnation, lamination and / or film coating. In addition, the protective layer, the layer, the carrier layer and / or the film layer can be at least partially transparent and / or translucent, in particular translucent. The protective layer is preferably at least partially transparent and / or translucent in such a way that in at least one overlap area with the film layer the composite of the film layer and the protective layer is transparent and / or translucent, so that the layer, preferably arranged on the film, Metal layer in the transparent and / or translucent overlap areas on the user side shows through optically. Consequently, the metal layer is recognizable at least in some areas on the user side. In addition, the layer, protective layer, the carrier layer and / or the film layer can have pigmentation and / or be colored, preferably through-colored, and / or be coated on the top and / or underside. Ultimately, the protective layer can also influence the optical appearance of the multi-layer structure, for example to achieve a decor of the entire multi-layer structure or to optically design and / or change the multi-layer structure.

In addition, the film layer can be designed as a protective layer. Accordingly, the metal layer is preferably arranged on a carrier layer, with the film layer designed as a protective layer being arranged on the metal layer and / or the carrier layer, in particular on the top side, facing the user side. The protective layer can protect the element and / or the metal layer from mechanical stresses. The protective layer acts as an upper wear layer with a high scratch and / or wear resistance and is also highly insensitive to fingerprints. Consequently, preferably no fingerprints appear on the multilayered layer structure.

The cleaning and maintenance of the multi-layer structure, which is arranged on an element, is very easy for the user, whereby cleaning and / or wiping strips can be reliably prevented. This is shown in particular as an advantage for use as a floor covering element or for coating the floor covering element. The high abrasion resistance of the multilayered layer structure, which is provided by the protective layer, ensures long use of the multilayered layer structure.

According to a further embodiment of the inventive concept, it is provided that a plurality of at least single-layer protective layers are integrated in the multi-layer layer structure. For example, a protective layer on the upper side, facing the user side, can be provided on the multilayered layer structure. Additional protective layers can be integrated into the layer sequence of the multi-layer layer structure, in particular with the protective layer being designed as a damping layer.

With a damping layer, which is preferably designed as a plastic film, there is the advantage that unevenness in the carrier layer, for example a carrier plate, and / or a substrate is not on the use side of the Draw the multilayered layer structure. In addition, the protective layer designed as a damping layer can prevent unevenness on the surface of the element facing the multilayer layer structure - the usage side of the element - after application of the multilayer layer structure. In practice, this marking is also referred to as "telegraphing" bumps. The damping layer consequently prevents such telegraphing.

In addition, protective layers in the form of a coating can also be provided between the layers, at least in some areas, for example to influence the optical appearance of the multilayered layer structure and / or to seal or protect the, preferably partial-area, decorative layer. Furthermore, the protective layer can also be provided to protect the underside of the multilayered layer structure. Likewise, the protective layer can also be designed as protection for the metal layer, in particular the metallization, in particular the protective layer then being in the form of a coating and / or plastic film layer or plastic film. A protective layer of the type mentioned above can be used, for example, to arrange the multilayer structure on the element.

Furthermore, the film layer and / or the biopolymer-containing and / or bio-polymeric layer can be printed at least in some areas. Such printing can preferably be provided to form the decorative layer, which has been applied at least in part to the film layer and / or the layer. Preferably, the film layer and / or the layer in the unprinted areas, which in particular are not covered by the decorative layer, is transparent and / or translucent. The film layer and / or the layer, in particular the combination of the film layer and the decorative layer, can moreover be designed to be translucent in the printed areas.

Preferably, therefore, the metal layer can be overlaid with the decorative layer, the decorative layer being translucent, in particular in such a way that the metal layer is optically visible at least in regions from the use side of the multilayered layer structure.

Alternatively or additionally, the metal layer, in particular to form the decorative layer, can be printed at least in regions. The film is preferably at least partially transparent and / or translucent; and more preferred in those areas in which the printed metal layer and / or the unprinted metal layer should be optically recognizable from the outside - that is, from the usage side.

In particular, the decorative layer consists of a printing and / or coating device and / or has this. The decorative layer in the form of a coating can be in the form of a varnish, coating and / or a film, in particular an adhesive film, preferably based on paper and / or plastic.

In a further preferred embodiment, the at least one decorative layer on the user side of the layer structure is facing and / or facing away from the layer, the film layer, the protective layer and / or the metal layer. Ultimately, it goes without saying that a plurality of decorative layers can also be integrated into the layer structure. The decorative layer can be produced by printing and / or coating the layer, the film layer, the protective layer, the carrier layer and / or the metal layer. In addition, the decorative layer can be formed as a full-area and / or partial-area, preferably interrupted, layer. A partial and / or interrupted design of the decorative layer allows the metal layer to be covered at least in some areas, in particular with the decorative layer being opaque in those areas. Thus, the optical appearance of the multi-layer structure can be predetermined by the, in particular interrupted, decorative layer and the metal layer, which is preferably optically recognizable from the user side of the multi-layer structure.

The decorative layer is preferably at least partially transparent and / or translucent, in particular translucent. As an alternative or in addition, the decorative layer can have a partial surface. The above-mentioned embodiments can in particular be designed such that the metal layer, in particular on the top side, facing the user side, is visible at least in some areas, preferably optically recognizable and / or optically shining through. According to this, the decorative layer can be at least partially transparent and / or translucent in the case of a full-surface design as a layer, so that the metal layer, which is preferably provided on the underside of the decorative layer, can be seen from the outside on the user side.

In this context, it is particularly preferred that the, preferably printed, decorative layer, at least in some areas, is a decor based on the imitation a material and / or a texture, in particular a natural material and / or a natural texture, preferably based on a wood, stone material and / or concrete, tile, ceramic, metal material and / or on the basis of a graphic and / or photographic and / or typographic elements and / or a decor having a natural and / or artificial patina texture. Consequently, in combination with the decorative layer, the metal layer can preferably provide the optical appearance and achieve textures or imitations of a material that cannot currently be used for the elements of the use according to the invention. A patina texture is understood to mean in particular a decorative layer with wear, aging and / or weathering effects, in particular the so-called "vintage look" or "used look". A patina texture can include scratch marks, scratch marks, damage, discoloration and / or flaking, which are particularly visible on a surface. An imitation of a patina surface based on a real model and / or an artificially, artistically, creatively and / or graphically generated patina texture can also be provided in the decorative print.

In tests which were carried out while the invention was being established, it was found that a metal layer made of polished and / or high-gloss chrome, copper and / or gold can be seen as a metallic layer even after the decorative layer has been printed on. This applies in particular when the printing has been carried out with low color opacity and / or color saturation. A matt metal surface can be achieved by printing. The high-gloss metal surface can be influenced by translucent, glazing printing in the degree of gloss, so that the finest nuances between the high-gloss and matt metal surface can be specifically adjusted. As a result, the visual and creative scope is greatly expanded. In particular, there is also a logistical advantage, since no additional matt metal types have to be kept in order to produce a matt metal surface. Even brushed metal surfaces can be imitated with a brush structure thanks to the decorative layer. Advantages arise in particular in the case of the translucent and / or printed decorative layer arranged above the metal layer, preferably in front of the transparent film layer formed as a plastic film. It was also found in the tests that the color yellow as a translucent printed layer, for example in the background, in combination with a high-gloss chrome surface has an optically gold-metallic effect. Thus, the choice of colors and the coloring can be combined with one another in a targeted manner. Translucent printed color ben can get a metallic, shiny appearance through the metal layer.

Consequently, in the use according to the invention, a known element can be refined in such a way that imitations which are currently unreachable, preferably metal imitations, can be produced. The visual appearance for the decor can also be achieved by the at least partially colored layers, in particular the film layer and / or the protective layer, in particular in combination with the decorative layer. An imitation of the aging of the metal layer can also be achieved in this way. For example, rust or traces of usage of the metal layer can be represented graphically by the aforementioned layers.

A connection layer is preferably provided on the outside of the multilayered layer structure, in particular on the underside, facing away from the user side. The connecting layer can be designed as a paper layer resinated with melamine resin and / or as an adhesive layer, which preferably has a polyacrylate adhesive, and / or as a layer comprising a paper, nonwoven and / or fabric. The connecting layer is preferably designed as a biopolymer-containing and / or biopolymeric layer according to the invention.

The connecting layer can be used for coupling or for connection to the element, preferably when the multilayered layer structure is laminated onto the element. Ultimately, it is also conceivable to design the multilayered layer structure as an adhesive film, it being possible for the adhesive function to be provided by the connecting layer.

Furthermore, the connecting layer can have a compensating, protective, adhesive, adhesive, damping, connecting and / or adapter function.

In addition, it is preferably provided that the protective layer, carrier layer, film layer, connecting layer and / or the decorative layer have and / or consist of a biopolymer-containing and / or biopolymer material. In particular, the entire layer structure consists of a biopolymer-containing and / or biopolymer material.

In particular, a material based on wood, cellulose, lignin, starch, sugar, vegetable oil, chitin, casein, gela is used as the biopolymer or biopolymer-containing material. tine, crab shells, animal and / or vegetable proteins, fungi, insects, bacteria, zein and / or algae, understood.

The aforementioned biopolymer-containing materials can also provide the properties required for the layer. A biopolymer-containing plastic can also be referred to as "bioplastic" and consequently include a large number of vegetable and animal raw materials. The most important raw materials are wood, especially for cellulose and lignin, cereal plants and potatoes for starch, and sugar cane and sugar beet for sugar, as well as oil plants, especially vegetable oils, and insects for chitin, shell and crab shells. Cellulose-based plastics are in particular celluloid, cellophane, viscose and lyocell, as well as cellulose acetate and lignin-based biopolymers, preferably with the addition of natural fibers made from hemp or flax. Furthermore, cellulose-based biopolymers of cotton can be used according to the invention.

Modified cellulose is also conceivable using enzymes for the biopolymer and / or the biopolymer-containing material. Starch-based biopolymers are mostly obtained from corn, wheat, potatoes, sugar cane and / or sugar beet. The starch includes, in particular, thermoplastic starch (TPS), polylactic acid or polylactide (PLA), polyhydroxyalkanoates, in particular polyhydroxybutyrate. Polyester and / or thermoplastic biopolyesters, such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and / or polyethylene furanoate (PEF) are also possible.

In addition, fatty acids can be obtained from vegetable oils, which can be converted into high-quality bioplastics via several chemical intermediates. Vegetable oil-based plastics are in particular biopolyamides (Bio-PA) and bio polyurethane (Bio-PU).

Furthermore, as mentioned above, raw materials for biopolymers are casein, a protein from milk, gelatin, a protein from animal bones or skin, chitin, a polysaccharide from fungi, insects (chitosan) and / or crab shells. Polyhydroxybutyric acid (PHB), which is obtained from bacteria, is also provided according to the invention as a biopoly mer.

Ultimately, it goes without saying that polymeric and / or biopolymeric material mixtures of the aforementioned plastics can also be used according to the invention. In a further preferred embodiment it is provided that the biopolymer-containing and / or biopolymeric layer, the decorative layer and / or biopolymer-containing and / or biopolymeric further layers of the layer structure, in particular the protective layer, the carrier layer, the film layer and / or the compound layer, polyvinyl alcohol (PVAL), polyvinyl butyral (PVB), polycaprolactone (PCL), polyactide (PLA), bio-copolyester, terpolyester, bio-polyurethane (bio-PUR), bio-polyamide (bio-PA), starch polymer, preferably thermoplastic Starch (TPS), cellulose polymers, lignin, vegetable oil-based biopolymers such as rapeseed oil, castor oil, soybean oil and / or sunflower oil, chitin, chitosan, casein plastics (CS / CSF), gelatin, polyester, thermoplastic biopolyester, polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polyethylene furanoate (PEF), polysaccharides (multiple sugar), bio-based acids, such as succinic acid and / or lactic acid, polyhydroxy butters acid (PFIB), polyamino acids and / or lipids and / or consists thereof.

The aforementioned materials are characterized by their training as a growing raw material and / or by their biodegradability. Especially with regard to the expected rising raw material prices and a raw material shortage of petroleum, those plastics are preferred according to the invention which are not petroleum-based and in particular are designed as biopolymers.

In particular, the metal layer can be formed as a metallization, as a metallic and / or metal-containing printing, painting and / or coating of the carrier layer, the film layer and / or the protective layer. Consequently, the metal layer is preferably applied to the carrier layer. Metallization is understood to be the coating of a material, in this case the carrier plate, with a metal layer. In particular, a plastic metallization is hen, consequently a coating of a plastic material with a metal layer. The advantage of a metallization is the low weight of the metal layer, the insensitivity to corrosion, especially in combination with a protective layer, and the provision of a decorative and, if appropriate, technical purpose. A coating with the metallic material can be achieved, for example, by electroplating, so that a metallic deposit (coating) can be produced on a substrate (carrier plate).

In a further embodiment of the concept of the invention, the metal layer is transparent and / or translucent, in particular light, at least in some areas. permeable, educated. Through an at least partially transparent and / or translucent design of the metal layer, the surface of the element on which the multilayered layer structure is arranged or can be arranged can be optically visible and / or optically from the user side of the multilayered layer structure after application to the element be recognizable. A transparent and / or translucent formation of the metal layer can be achieved in particular when the support layer is metallized and / or printed.

In a further very particularly preferred embodiment, the metal layer is provided both on the top side, facing the user side, and on the underside of the carrier layer. In particular, different metal layers can be arranged on the carrier layer. A plurality of support layers and metal layers may be present. In particular, the metal layers can overlap, after which different optical and design options are created. It is conceivable that an element is visible both on the user side and on the side opposite the user page. In addition, different technical properties can be achieved by using different materials of the metal layer. By coating the carrier layer on both sides, the strength of the multilayered layer structure can also be increased.

The metallic coating of the metal layer can be by means of thermal spraying, preferably wire flame spraying, powder flame spraying, arc spraying, plasma spraying and / or high-speed flame spraying (HVOF), and / or by means of powder coating, in particular electrostatic powder coating (EPS), and / or by vortex sintering and / or by means of vacuum coating be applied. The metal-containing coating is preferably applied by means of a thin layer process. The aforementioned methods are distinguished by their high economic efficiency, in particular since the metal layer has a comparatively small layer thickness due to the abovementioned options for application, in particular in comparison to a metal plate and / or a metal sheet.

According to the invention, the metal layer can also be applied as a metal glaze, in particular on the carrier layer made of ceramic and / or porcelain stoneware.

In addition, the adhesive strength or cohesion of the metal layer and / or the multilayered layer structure can be determined by different methods for coating. tion can be influenced in a targeted manner. In thermal spraying, the coating material, ie the material of the metal layer, is heated. Individual particles are released from the material of the metal layer and these are accelerated in such a way that they are applied to the substrate material, that is to say the carrier plate, by means of a shot. The particles of the metal layer then solidify on the surface of the carrier plate.

The layer thicknesses of the metal layer can usually be greater than or equal to 50 μm when applied by thermal spraying.

In physical vapor deposition (PVD) or physical vapor deposition, sputter deposition and / or thermal evaporation can be used. In sputter deposition, a coating material or a target (in this case the carrier layer) is bombarded with particles in a high vacuum. By removing the coating material and accelerating it onto the carrier layer, layer thicknesses of 3 nm to 5 pm can be deposited. Coatable plastics in particular must be able to be evacuated. This is significantly influenced by the initial behavior and the water absorption of the plastic.

In plasma-assisted gas phase deposition (chemical vapor depositon; CVD process), the deposition of materials is made possible by a chemical reaction.

In addition, it is also conceivable to apply the metal layer by galvanic deposition. In the galvanizing or in the galvanic deposition, a metal is applied to a carrier layer, in particular to a plastic carrier layer - the so-called plastic galvanization. Most plastics are not electrically conductive, so the surface must first be covered with a well-adhering, electrically conductive layer for a subsequent electrolytic coating. The above-mentioned coating processes are used in particular for this. The following process steps are required for galvanization:

- Pickling with oxidative metal salt solutions to roughen the surface and / or

- Activation with metal nuclei, especially palladium, and / or chemical metallization to form a conductive layer, in particular a thin layer between 0.3 and 4 gm of copper or nickel is produced by reduction from their metal salts,

Advantageously, very thin metal layers can be provided according to the invention, which have preferably been applied to a carrier layer. With a layer thickness in the abovementioned areas, the environmentally friendly and / or resource-saving advantages of the present invention are evident, since no thick metal plate in the mm range has to be used for the layer structure. A comparatively very thin metal layer on the film layer and / or the carrier layer can already ensure the metallic surface of the multilayered layer structure and consequently of the entire element.

In addition, it can be provided that the metal-containing coating and the carrier layer have a total layer thickness as a composite from 0.5 pm to 1000 pm, preferably from 5 pm to 400 pm, more preferably from 20 pm to 150 pm.

Alternatively or additionally, it can be provided that the metal layer has and / or consists of a semimetal and / or a semimetal alloy. In principle, it is also conceivable that the metal layer has different metals and / or different areas, in each of which at least one metal has been applied.

A metal layer formed as sheet metal ensures a high strength of the multi-layer structure and can be used to stabilize the element and / or to increase the overall strength of the element.

Since the metallized layer is sensitive to abrasion and moisture, there is advantageously a surface protection, in particular in the form of a protective layer.

In a further preferred embodiment of the inventive concept, it is provided that the biopolymer-containing and / or biopolymeric layer is designed to be elastic and / or flexible.

Surface sealing is to be understood as meaning thin, transparent layers that are applied after laying on the multilayered layer structure. Surface finish refers to an applied layer of less than 50 pm. Surface finishes protect the underside layer structure and improve the usage properties of the entire layer structure, after which the costs for cleaning and maintenance can be reduced and the value retention of the entire element can be increased.

Furthermore, the surface structure can also be used due to its functional property (s), in particular for slip resistance.

The surface finish can be applied both directly to the metal layer and / or on the top side to the plastic film or the film layer.

For example, an aqueous PU coating can be provided as the protective layer. In addition, the protective layer can be produced by lamination, in particular flame lamination, sprinkling of meltable, powdered plastics and subsequent melting.

In a further preferred embodiment, the layer, the film layer, the protective layer and / or the metal layer has a structured surface. In particular, the structured surface is treated by mechanical treatment, in particular polishing, sandblasting, satinizing, glass bead blasting, grinding, milling, drilling, scoring, brushing, lasering, engraving, laser engraving and / or embossing, and / or by a chemical surface treatment, in particular Etching, patination, and / or coloring, can be generated. The structured surface or the structures in the surface can influence the visual appearance, in particular in such a way that the decor or the effect of the decor supports or is highlighted. The structured surface can also be used for slip resistance. In the case of a floor covering in particular, it is usually perceived as pleasant if it has a structure - in the end it approximates a "real" natural material.

Wood and / or stone structures can be imitated through the surface structures.

The structured surface of the layer, the metal layer, the protective layer and / or the film layer is preferably at least substantially in synchronism with the decor of the decorative layer - in the manner of a synchronous pore. A synchronous pore is characterized, for example, by the fact that if the decoration or the decorative layer visually represents a depression, this depression is ultimately also found in the multilayered layer structure, so that the optical appearance of the depression is supported by the structured surface. This creates an authentic visual appearance of the multi-layer structure.

In addition, the structured surface of the biopolymer-containing and / or biopolymeric layer, the film layer, the protective layer, the carrier layer and / or the metal layer can have a layer thickness of 0.01 mm to 10 mm, preferably 0.05 mm to 2.5 mm, exhibit.

In this context, it is ultimately understood that it is preferred according to the invention that the structured surface of the aforementioned layers also results on the user side of the multilayered layer structure. It can thus be provided that the layers lying above the structured layer adapt or conform to the structured surface. Consequently, the top side or the user side of the multilayered layer structure preferably has a structuring with a depth of 0.01 mm to 10 mm, preferably 0.05 mm to 2.5 mm.

Due to the metal layer and / or a plurality of metal layers integrated in the multilayer layer structure, there are possibilities for using the functional and technical properties of the metal layer for the element.

Consequently, the aforementioned properties can be drastically improved by the multilayer structure. Thus, the multilayered layer structure can be designed such that the element with an applied layer structure is designed to be waterproof at least on the loading side. Furthermore, the metal layer can be used specifically to conduct electricity, so that it is conceivable that the metal layer as a functional layer is an electrically conductive layer. In particular, the metal layer can be designed as a conductor track.

A layered composite of the biopolymer-containing and / or biopolymeric layer, film layer, the protective layer and / or the preliminary product can form a composite film. The individual layers of the composite film can be extruded or laminated or laminated.

Suitable laminating agents such as lacquer, glue and / or wax can also be used. Is laminated to protect and / or decorate a material and / or to achieve an addition of favorable material properties. The material can be applied on or under a layer with the desired properties or placed between two layers. For printing, gluing and / or coating a plastic film, preferably the film layer, a corona pretreatment is generally necessary - as mentioned above - for some plastic materials, in particular polyethylene, polypropylene and / or polyethylene terephthalate. The surface to be treated is exposed to an electrical corona discharge for a short time. Alternatives to corona treatment are flame treatment, plasma treatment and fluorination. Processing is preferably carried out from the roll, in particular the roll laminating machine, or as surface lamination, in particular with a surface lamination system.

According to the invention, the multilayered layer structure can be provided for changing and / or improving functional-technical properties and / or functions of the element.

According to the invention, it is possible to improve the layer structure known from practice by integrating a metal layer. Because of the metal layer, the functional and technical properties of the layer structure and in particular special of the element can be changed in a targeted and functional manner, preferably improved. Consequently, according to the invention, a layer structure can be provided which, in addition to the visual representation of a decor, can purposefully influence technical properties of the element.

This opens up a multitude of possible uses of the multilayered layer structure, so that the multilayered layer structure can also be applied to elements without having to focus on redesigning and redesigning the elements. According to the invention, the layered structures can be used with regard to their technical and functional properties - not because of their aesthetic and decorative character. The layer structure can serve as a component of the element to influence the properties of the element and contribute directly to the fulfillment of important technical functions.

In a particularly preferred embodiment of the invention, it is provided that the multilayered layer structure is provided for deriving electrostatic charges. In particular, the electrical properties of the element can be improved. In the case of metallized plastic films, in particular, an electrostatic charge, in particular the plastic film, can be discharged via the metal layer, in particular the metal layer being electrically conductive. Especially with furniture surfaces and / or floor coverings made of a plastic material, an electrostatic charge, especially the layer structure, is problematic. The surfaces can become electrostatically charged due to friction, for example caused by walking on floors with plastic surfaces that have polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA) and / or polyvinyl chloride (PVC). According to the invention, the charge can be discharged through the correspondingly conductive metal layer. If necessary, further earthing measures are planned.

According to the invention, these are optional, the discharge function being controllable and / or improving through the grounding measures.

According to the invention, a conductive material is understood to be a material whose electrical resistivity is less than 10 ⁴ Om. As a result of the electrically conductive design of the metal layer, the metal can accordingly conduct electricity and thus reduce, in particular eliminate, the electrical charge. Consequently, according to the invention, electrostatic charging of the single or multi-layer upper layer structure of the egg mentes can be derived through a metal layer, preferably via a plastic film metallized with aluminum, the plastic film being designed as a film layer.

Furthermore, the multi-layer structure can be provided for shielding electrical, magnetic and / or electromagnetic radiation. In particular, the multilayered layer structure serves to shield magnetic fields, such as the earth's magnetic field and / or electromagnetic fields, due to telecommunications, electronic devices, microelectronic devices, lightning, navigation, systems for power supply, microwave ovens, ignition and / or drives. Ultimately, an electrical, electromagnetic and / or magnetic field is to be understood as any field that has an influence on the element according to the invention. In particular, noble metals, preferably copper, aluminum, iron and / or steel and / or ferromagnetic alloys, lead and / or metallized plastics, fabrics and / or nonwovens are suitable as materials for shielding the metal layer. In particular, a plurality of multi-layer structures can be arranged on the element and / or a plurality of foil layers and / or metal layers can be integrated in the layer structure to shield an element. According to the invention, a very economical solution for shielding the element from electrical shear, electromagnetic and / or magnetic radiation or fields can be provided.

In addition, the multi-layer structure can be used for preventive fire protection, preferably for flame retardancy. According to the invention, a flame-retardant effect of the multilayer layer structure can be achieved in that the metal layer cannot be made combustible, after which the combustibility and / or flammability of the entire element improves. The low flammability of a material and / or element is particularly important for object use and / or protective construction. Metal oxides, metal hydroxides, metal salts and / or boron and / or zinc compounds and / or silicon compounds are particularly suitable for the flame-retardant metal layer, in particular the metallic or metal-containing coating. Advantageously, a plurality of the same and / or different metal layers are arranged in the layer structure for the flame-retardant effect.

The visible wavelength range extends from 380 to 750 nm; the infrared range begins with radiation with a wavelength greater than 750 nm; the UV range is characterized by radiation with a wavelength of less than 380 nm. An external, the sun radiation side facing, sun protection of the element can be based on reflection, with an internal sun protection of the element facing away from the sun radiation side by absorption who can ensure the. In particular, a film layer coated with aluminum can reflect not only visible light and infrared radiation, but also UV radiation. This distinguishes an aluminum coating from layers that have silver and / or gold. In particular, the reflectance of aluminum is largely independent of the wavelength. The degree of reflection of the metal layer used can be greater than 70%, in particular for all wavelength ranges, preferably between 85% and 100%; specifically above 800 nm in the near infrared range. For the use of the element as a film roller blind, an outward-facing user side or film layer facing the solar radiation can be vapor-coated with aluminum to form the metal layer, which in particular reflects up to 80% of the incident sunlight, the reflection in particular also being selective and consequently changing the light can be trained.

A sun protection film and / or a multilayered layer structure for sun protection can in particular have a film layer made of polyethylene terephthalate (PET), which can be applied in particular to a window, so that light and / or heat from the solar radiation that can be transmitted through the window is reducible. It is preferably provided that the metal layer and / or the multilayered layer structure filters UV-A and / or UV-B radiation. A UV-A radiation is in a wavelength range from 315 to 380 nm. The UV-B range is provided in a wavelength range from 280 to 315 nm.

Preferably, the sun protection can be achieved by reflecting the metal layer, and absorption of the radiation can also be provided. Depending on the intended use and / or formation of the layer structure, the radiation emanating from the sun can be reflected and / or absorbed. In this context, it can be provided that the film and / or the multilayered layer structure is made optically darker with higher sun protection.

A metal layer designed as an electrical conductor track preferably has aluminum, copper, gold and / or silver as the material.

Ultimately, the metal layers with different polarity can also be arranged in the same plane in the layer structure, in particular in which the metal layers are then electrically insulated from one another.

The multilayered layer structure and / or the element particularly preferably has an S _d value of less than 1500 m, preferably less than 1000 m, more preferably between 0.01 to 500 m and at least essentially between 0.1 to 100 m , In particular, the multilayered layer structure and / or the element, as mentioned above, is designed to be diffusion-inhibiting and / or diffusion-tight.

The S _d value characterizes the air layer thickness equivalent to water vapor diffusion. This is a building physics measure for the water vapor diffusion resistance of a component or a component layer. The S _d value clearly indicates a thickness that a dormant air layer must have so that the same diffusion currents flow through it in steady state and under the same boundary conditions - in comparison to the component under consideration. The above values refer to DIN 4108-3 (as of July 2018) and also characterize a diffusion-inhibiting and / or diffusion-open layer.

Furthermore, the invention relates to a method for producing a multilayered layer structure according to one of the previously described embodiments, where the decorative layer is directly and / or indirectly connected to the biopolymer-containing and / or biopolymer layer.

Ultimately, it goes without saying that the aforementioned advantages and / or preferred embodiments of the multilayered layer structure can also be applied to the method according to the invention, so that reference can be made to the previous statements in order to avoid unnecessary repetitions.

In a particularly preferred embodiment of the method according to the invention it is provided that the metal layer is applied to a carrier layer and / or layer, in particular the film layer, by means of a metallic and / or metal-containing coating. In manufacturing technology, the process step of coating is understood to mean such a process that is used to apply a firmly adhering layer of formless material, in the present case a metal-containing material and / or metal, to the surface of a workpiece, in particular the carrier layer , Before coating, the material of the metal layer is in particular melted and / or converted into a liquid state.

Due to the firm bond of the metal layer to the layer, which is preferably designed as a film layer, which can be provided directly and / or indirectly, a multilayered layer structure can be produced, which can be applied to an aforementioned element to achieve an at least partially metallic surface. Alternatively or additionally, it can be provided that the carrier layer and / or the layer, preferably the film layer, is lacquered, printed and / or metalized with a metallic and / or metal-containing material to form the metal layer. Metallization is understood to mean the coating of a material with a metal layer, whereby basically different methods of thin-film technology can be used for the metallization:

Physical vapor deposition (PVD), such as

• Sputter deposition

• thermal evaporation

Chemical vapor deposition (CVD)

• Plasma-assisted chemical vapor deposition (physical-enhanced chemical vapor deposition, PECVD) thermal spraying

Electroplate.

Printing on the carrier layer and / or the layer, in particular the film layer, is preferably by means of digital, anodized, inkjet, offset, gravure, flexographic, screen and / or 3D printing and / or transfer printing Thermal transfer printing, sublimation printing and / or direct printing carried out. Alternatively or additionally, the pressure can be transferred by means of an embossing foil, preferably hard-stamping foil and / or cold embossing foil, and / or applied by means of micro-contact and / or rotary coating. Ultimately, the aforementioned methods serve to apply the metal layer in such a way that the comparatively thin metal layer is firmly on the carrier layer, preferably the film layer.

In 3D printing, surface structures can be created during the printing process, in particular the metal layer. The preferred layer thickness of a metal layer applied by means of 3D printing is between 5 pm and 2000 pm, preferably between 10 pm and 1000 pm. Ultimately, it goes without saying that a printing process as a combination of 2D and 3D printing is also possible. It is particularly preferred that the metal layer is applied to the carrier layer by electroplating.

In particular, an anodized, galvanized, chromated, chrome-plated, burnished and / or galvanic coating can be provided.

Alternatively or additionally, it is conceivable that the metal-containing coating is applied by means of thermal spraying, wire flame spraying, powder flame spraying, arc spraying, plasma spraying and / or high-speed flame spraying (HVOF). The abovementioned possibilities of spray application enable the metal layer to be applied to the carrier layer in a targeted and purposeful manner, whereby comparatively small layer heights or layer thicknesses of the metal layer can be guaranteed and specifically only those areas of the carrier layer are metallized which have the metallic surface on the user side of the multilayer layer structure should generate.

In addition, it can also be provided according to the invention that the metal-containing coating of the metal layer is applied by means of vacuum coating, preferably vacuum evaporation, plasma coating, physical vapor deposition (PVD) and / or chemical vapor deposition (CVD).

The metallization can in principle be carried out with any of the materials of the metal layer mentioned above. Preferably, a carrier film with a very thin layer, in particular of pure aluminum in powder form with an aluminum content of at least 99.98%, is evaporated in a high vacuum. Metallization with zinc or alloy, a zinc-aluminum alloy and / or with copper is also preferred. Chromium, iron, gold, molybdenum, palladium, silver and / or titanium and their alloys, in particular nickel-chromium alloy, copper-aluminum alloy, constantan, monel and / or gold-tone alloys are also particularly preferred.

The processes of physical vapor deposition (PVD) are vacuum-based coating processes in which the coating material, in this case the metal, is converted into the gas phase with the aid of physical processes and then as a thin layer, that is, as a metallization. condensed on the substrate, in particular the carrier plate. Thermal evaporation and cathode sputtering (sputtering, in particular magnetron sputtering) are preferably used as the PVD method. Further sales Driving possibilities are arc vaporization, ion plating, silver passivation and / or the sol-gel process. The metallization is preferably carried out from roll to roll of the backing layer, in particular the backing layer and / or layer stored in roll form and designed as a plastic film.

It is advantageous that metallized polyethylene films, polypropylene films and / or polyamide films have very good barrier properties against oxygen, gases and moisture. The metallized film can then also be printed, laminated against other films and / or used as a composite film.

Colored metallic effect foils or metallic effect foils with silver tones can also be used. Colored chrome effects or special effects, such as flolograms in particular, are also preferably used.

The degree of gloss of the metallized carrier layer can vary between matt to high-gloss, the degree of gloss being determined by the method of application and the type of material. Ultimately, it goes without saying that the more shiny the surface of the carrier layer, the more intensely the metallic effect becomes visible.

It is very particularly preferably provided in connection with the invention that aluminum vapor deposition takes place. This saves resources and is environmentally friendly since only minimal use of aluminum is necessary. Compared to aluminum, gold, copper and titanium have high raw material prices. In order to be able to imitate these colors, however, it is advantageous to choose a metallization with aluminum as the metal layer and to this a preferably translucently colored and / or pigmented plastic film, in particular a plastic film, protective layer and / or film layer, preferably comprising polypropylene and / or polyethylene terephthalate (PET).

A gold tone can be created by using a translucent yellow pigmented film if a support layer coated with aluminum is used. The metallic sheen of the aluminum vaporization is still visible through the translucent colored film. With a transparent, red-brown colored foil, for example, a copper tone and / or with gray color pigments the appearance of stainless steel and / or titanium can be created. As an alternative to using a colored and / or pigmented plastic film, in particular a layer, protective layer and / or film layer designed as a plastic film, a transparent film can be provided on the top side with a pigmented, translucent coating, preferably a lacquer and / or a printed base , in particular wherein the coating is designed as a protective layer. In this context, the aluminum vapor deposition can preferably be applied on the back of the film layer and / or the layer facing away from the user side. If a translucent glaze is printed on the background, an adhesion-promoting, transparent color-ink absorption layer can be seen on the top of the film layer and / or the layer.

The aforementioned colored and / or pigmented films, in particular the layer, protective layer and / or film layer formed as a plastic film, can have a variable degree of translucency, the translucency depending on the desired optical effect between 0% (fully opaque; opaque) and 100% (transparent, crystal-clear, clear-sighted), preferably between 10% and 70%, can be provided.

In a further preferred embodiment of the method it is provided that the layers of the multi-layer structure are connected to one another by lamination, by co-extrusion and / or lamination, in particular by means of a roll lamination method and / or surface lamination method. Laminating is understood to mean connecting several layers of the same or different materials with the aid of suitable laminating agents, preferably lacquer, glue and / or wax. Basically, the lamination can be divided into three forms:

- wet lamination

- Connection using a wet adhesive

- dry lamination

- Connection using a dry adhesive

- thermal lamination

- Connection without adhesive, by means of heat and / or pressure.

In the case of wet lamination, a viscose dispersion adhesive, in particular based on polyurethane, is applied to the film in layers, in particular with a layer thickness of 7 to 25 pm, and first dried in a drying device. net. The adhesive is often two-component. The substrate is fed and combined with the film under pressure in a nip. The adhesive may then harden.

In dry lamination, the layered composite is produced with a dry adhesive, in particular where two-component reactive adhesives can be used for lamination, which are predominantly matched to the respective substrates. The application techniques of the laminating system are preferably provided via kiss coating, anilox roller application, nozzle and / or casting box principle. In particular, application weights between 1 g / m ² and 20 g / m ^{2 are} achieved.

For thermal lamination, the film is pre-coated with a thermoreactive adhesive. This can be melted by heat and combines the different materials under the action of pressure.

Lamination is understood to mean a material, thermal joining process that does not require the use of reflowing materials. By means of a lamination, preferably thin layers can be connected to a carrier material by means of an adhesive. The types of lamination can be divided into hard lamination, cold lamination and lamination using presses.

In the case of hard laminating, pressure and heat, in particular at temperatures between 60 to 120 ° C., result in a full-surface bond of the layer structure according to the invention on both sides. A possible combination between the film thickness and the area-related mass of the carrier layer and the metal layer and the film layer allows end products that are flexible, still rollable, and rigid.

In the case of cold lamination, films are coated with an adhesive which has normal adhesive properties, preferably over a wide temperature range, in particular between -75 ° C and 500 ° C. In the connection between the backing layer, in particular paper, and the film layer and / or protective layer, the adhesive acts like a double-sided adhesive tape.

In a co-extrusion, plastic melts of the same type or alien are brought together before leaving a profile nozzle and then pressed out through a shaping opening. In addition to the aforementioned methods, the layers, preferably in the form of plastic films, including the metal layer and / or a carrier layer and, if appropriate, a counter-pull provided under the carrier layer can be thermally bonded to one another in one process step, for example by hot pressing and / or hot bonding, especially in a hot press and / or a hot-melt press and / or a short-cycle press.

Another method for connecting the film layer and / or the layer and the metal layer is the thermal direct joining, in particular wherein the metal layer is electrically heated by resistance heating. If this is then brought together with the film layer, the plastic melts and forms a solid bond with the metal or the metal layer immediately after solidification.

In this context, it is particularly advantageous that the upper layer of the multilayered layer structure, in particular the layer, protective layer and / or the film layer, has a PUR film layer on the underside as an adhesion promoter to the carrier layer. PUR is characterized by the fact that it has a low melting point, so that this plastic melts when thermally bonded and thus serves as an adhesive layer or adhesion promoter between the other layers of the top layer of the multilayer structure and the metal layer.

Preferably, in particular on the upper side, facing the user side, at least in some areas at least one at least one-layer protective layer is applied to the layer, the film layer, the decorative layer and / or the metal layer. The protective layer can be formed as a protective film and / or protective coating. In particular, the protective layer is applied by means of lacquering, impregnation, lamination and / or film coating. The protective layer can be integrated in the multi-layer structure and / or can be arranged on the front side or the user side of the multi-layer structure, in particular to protect the layers underneath.

In addition, the protective layer can be dried after application, preferably by heat and / or infrared radiation. Alternatively or additionally, it is possible for the protective layer to be crosslinked after application, preferably by means of a hardener component. In particular, a two-component aqueous coating can be provided for crosslinking, the crosslinking by ultraviolet radiation, by electron beam curing (ESH) and / or heat me. The protective layer is consequently applied to an already existing composite and then dried, so that the protective layer is firmly connected to the layers arranged below and / or subsequently above it, in particular to the metal layer, the layer and / or the film layer.

Various methods can be used to produce the protective layer, in particular the surface finish, which differ in particular in characteristic features:

- Crosslinking aqueous coatings:

- UV-crosslinking aqueous coatings

physical drying by heat in drying channels and / or by infrared radiation

- thermal crosslinking by ultraviolet radiation (UV) - typical dry layer thicknesses 8 to 15 pm

- Heat-curing aqueous coatings

- chemical cross-linking due to high temperatures in dry channels

- typical dry film thicknesses 8 to 12 pm

- Two-component aqueous coatings

typical dry layer thicknesses 5 to 20 pm

- Crosslinking 100% systems chemical crosslinking and hardening - e.g. B. by ultraviolet radiation (UV)

- typical dry film thicknesses 10 to 25 pm; in two-shift orders up to 35 to 40 pm Thermal drying aqueous dispersions (not cross-linked)

- Mostly used as a temporary coating

- Removable with basic cleaner

- Typical dry layer thicknesses 5 to 12 pm

- Flushing through ESFI technology (electron beam hardening)

In addition, a large number of decorative layers can be applied to the aforementioned layers, in particular for optically influencing the decor of the multilayered layer structure.

In particular, the decorative layer is printed in a targeted and / or functional manner as a function of the metal layer.

The decorative layer is particularly preferably printed in digital printing. Both digital multi-pass and single-pass technology can be used for digital printing. Eco-solvent, latex and / or UV-curable inks are particularly preferably used. In particular, water-based printing inks are used according to the invention. In addition, gravure-identical color pigments - decorative gravure - can be used in the digital printing process and / or in other printing processes. For rotogravure printing and / or digital printing, the printing width is in particular between 5 cm and 300 cm, preferably greater than 60 cm, in particular between 125 cm and 225 cm. Printing is preferably carried out by industrial decor printing on an industrial decor printing machine. The decorative layer in the sense of this invention is based in particular on the imitation of material textures, such as wood, stone, concrete, tile and metal optics, as well as graphic decors and creative fantasy decors, in particular where the aforementioned optics can also be combined with one another , Decors of this type are particularly suitable for the design of surfaces for the preferred areas of application. According to the invention, a multitude of new design options are achieved in the interplay of decor printing with metallic material.

Transparent and / or translucent areas of the decorative layer can be achieved by printing with glazing, non-opaque printing inks, which in particular allow the metallic material of the metallic layer to show through, so that the metallic character and in particular the metallic luster remain optically recognizable. Depending on the desired optical effect, the translucency of a print can be between 0% translucent (fully opaque) and 100% translucent (crystal-clear), preferably between 50 to 100%. The metal layer is thus preferably clearly visible.

The biopolymer-containing and / or the biopolymeric layer, the protective layer, the film layer and / or the metal layer is / are preferably subjected to a mechanical surface treatment. In particular, the mechanical surface treatment is carried out in such a way that a structured surface of the aforementioned layers can be achieved, which is still at least partially present in particular on the use side of the multilayered layer structure. Polishing, sandblasting, satinizing, glass bead blasting, grinding, milling, drilling, scoring, brushing, lasering, engraving, laser engraving and / or embossing can be provided as the mechanical surface treatment. A so-called "butler finish" can be achieved for the metal layer by a brushing process.

Furthermore, the metal layer can be subjected to a chemical surface treatment, patination and / or coloring. As chemical surface treatment, an etching, preferably with an acidic material, can be provided in the metal layer. As a result, the metal layer is structured in a targeted manner, for example for improved adhesion with the layers to be arranged on the metal layer. According to a further embodiment of the method, the metal layer can be demetallized at least in regions. Ultimately, it is possible according to the invention for the metal layer to be applied over the entire surface and for the metal layer and / or the metal-containing coating to be removed in individual regions. In this way, for example, conductor tracks can be generated.

Furthermore, the film layer and / or the biopolymer-containing and / or biopolymer layer can be produced by extrusion, casting, calendering and / or blow molding. Ultimately, the film layer is designed in the manner of a film, in particular plastic film.

The biopolymer-containing and / or biopolymeric layer, the film layer, the backing layer and / or the protective layer is preferably pretreated before printing and / or coating, in particular with a corona treatment, flame treatment, plasma treatment and / or fluorination. The pre-treatment is preferably used to produce an adhesion-promoting, in particular transparent, ink-receptive layer and / or to produce an adhesion-promoting layer. A corona treatment is understood to be an electrochemical process for the surface modification of plastics, the treatment of the corona increasing the polarity of the surface, whereby the wettability and chemical affinity are significantly improved. The aforementioned layers are exposed to a high voltage electrical discharge during corona treatment. In the flame treatment, a flame treatment at a temperature of in particular 1000 ° C. can be provided, the molecule chains of the aforementioned layers being broken up and the oxygen molecules contained in the flame being incorporated. In this way, improved liability can be achieved, which is particularly advantageous for further processing. In fluorination, the introduction of fluorine into organic compounds with the aid of fluorinating agents is provided.

The decorative layer can be printed directly on the untreated material and / or on a color ink absorption layer, which has been applied in particular to the metal layer and / or the film layer. The color ink absorption layer is designed as an adhesion-promoting and / or transparent layer.

Furthermore, the film layer and / or the at least single-layer protective layer can be extruded and / or laminated onto the metal layer. Alternatively or additionally the at least one-layer protective layer can be extruded and / or laminated onto the film layer. Lacquer, glue and / or wax are used in particular as laminating agents.

Preferably, the decorative layer, the layer, the protective layer and / or the film layer can be formed as a preliminary product or intermediate product and can be produced separately from the metal layer and only connected to the metal layer and / or the carrier layer in a subsequent process step.

A composite layer comprising the layer, the film layer, the protective layer and / or the preliminary product can form a composite film. The individual layers of the composite film can be extruded or laminated or laminated. The provision can be made by laminating several layers of the same or different materials or layers, in particular of plastic films. Suitable laminating agents such as lacquer, glue and / or wax can also be used. Ka schiert is to protect and / or decorate a material and / or to achieve an addition of favorable material properties. The material can be applied on or under a layer with the desired properties or placed between two layers. For printing, gluing and / or coating a plastic film, preferably the film layer and / or the layer, a corona pretreatment is generally necessary - as mentioned above - for some plastic materials, in particular polyethylene, polypropylene and / or polyethylene terephthalate. The surface to be treated is exposed to an electrical corona discharge for a short time. Alternatives to corona treatment are flame treatment, plasma treatment and fluorination. Processing is preferably carried out from the roll, in particular the roll laminating machine, or as surface lamination, in particular with a surface lamination system.

The above-mentioned composite film can in particular be provided on the underside with a melamine-coated paper as the connecting layer. It is advantageous here that the composite film can be pressed in a short-cycle press, in particular on a sheet material such as FIDF and / or MDF. The compression takes place under pressure and flash, especially at temperatures of 160 to 200 ° C. The melamine becomes liquid in the resin-coated paper and combines with the FIDF plate through the pressing process. The melamine-coated paper takes on the adapter function for processing the composite film in a short-cycle press. Vo- A prerequisite for technical feasibility is in particular the use of a composite film according to the invention, which is preferably stable in a temperature range from 160 to 200 ° C. Ultimately, this means that the individual components of the composite film used, such as the plastic and / or the laminating adhesive, must meet these temperature requirements. For example, the melting range of polypropylene is around 160 ° C +/- 10 ° C. Polyethylene terephthalate has a melting point of 250 ° C +/- 10 ° C. Polyurethane has a melting point of 190 ° C +/- 10 ° C.

When forming the film layer as a transparent melamine layer, it is particularly appropriate that one or more transparent overlays are applied to the metal layer. The, preferably partially interrupted, decorative layer can be printed using one of the previously described printing methods, preferably directly on the metal layer and / or on the underside or top side of the overlay.

Fig. 8 shows the layer structure 1 according to the invention, it being shown schematically that the film layer 3 can be produced together with the metal layer 4, the decorative film 7 and the connecting layer 10 as a prefabricated composite layer or composite film. Then a lamination on a carrier Layer 5 take place. The preferred thickness of the composite layer is between 1 gm to 2500 gm. In principle, the composite layer can be applied to any suitable carrier layer 5 and / or any substrate, in particular substrate layer 12.

In the prefabrication, the layers of the pre-composite layer are joined, in particular by lamination with a roll laminating machine (thermal lamination or wet-dry lamination), laminating, thermal bonding and / or gluing and / or hot gluing or direct thermal joining. It is also possible to use a double-sided adhesive film as a connection layer. In addition, plastic films can be used in the layer structure 1, which are applied in the form of a molten plastic and in particular a molten polymer to form a protective layer 8, for example by calendering or casting. The connection to the carrier layer 5 can be made using different methods - for example, surface lamination on a surface lamination system.

The connection layer 10 serves as an adhesion promoter layer or self-adhesive layer for connection to the carrier layer 5. The connection layer 10 can also take on other functions - for example as a compensation layer for unevenness in the carrier layer 5. Especially when using a wooden plate as carrier layer 5, the roughness, irregularity or Unevenness in the carrier layer 5 is "telegraphed" through the composite film or the upper layer structure 1. In addition, the connecting layer 10 can also take on a protective function for the metal layer 4, in order to protect it from moisture and mechanical stress in the processing process, in particular against damage to the metal layer 4 by scratches. In addition, the connecting layer 10 can also perform a damping function, for example to improve the acoustic properties of the surface, in particular the impact sound in floor coverings. The connection layer 10 can also be formed as an adapter layer to a specific carrier layer 5, for example as a melamine-coated paper for pressing onto wood materials in a short-cycle press and / or as a paper and / or non-woven layer, in particular before gluing with paste on a plaster surface. In the formation of the metal layer 4 as a sheet or metal foil, the use of metal adhesives as a connecting layer 10 for connection to the T carrier layer 5 is technically advantageous. The embodiment of the multilayered layer structure 1 shown in FIG. 8 is intended in particular for the application area of wallpapers, decorative papers, decorative film and edging material in the form of a prefabricated composite film or for lamination on any carrier layer 5.

Another area of application is the provision of printed decorative papers or foils, finish foils (finished surfaces) and melamine foils for the wood-based panel and furniture industry with the application of coverings (wall, floor, ceiling), furniture, interior fittings and caravans.

According to the embodiment shown in FIG. 10, the film layer 3 is metallized. Alternatively, it would also be conceivable to use a metallized paper, in which case the metal layer 4 would have been applied to a carrier layer 5 formed as paper. The embodiment shown in FIG. 10 is intended for the application area of wallpapers, decorative papers, decorative foils and edging material in the form of a prefabricated composite film for lamination on any support layer 5 or base layer 12.

For better clarification of the individual layers, these are partly shown in the form of an exploded view. shown drawn together. The embodiment shown in Fig. 1 1 is in particular for the application of wallpaper, decorative papers, decorative foils and Kan tenmaterial in the form of a prefabricated composite film for lamination on any BE carrier layer 5 or subbing layer 12 is provided. It is not shown that a glazing, pigmenting lacquer layer can be applied as a protective layer 8 on the metal layer 4 in order to change the color of the metal. In principle, the metallized film layer 3 can be used in such a way that the metallized side of the film is located on both the top and the bottom - which is not shown in FIG. 11.

For printing, the protective layer 8 has a color ink absorption layer 11 which has been produced by a pretreatment. The color ink receptive layer 1 1 enables the protective layer 8 to be printed on. The color ink receptive layer 11 also serves as an adhesion-promoting layer. If necessary, the protective layer 8 is colored and / or pigmented and formed as a plastic film, in particular as a transparent printing film made of polypropylene, PVC and / or PET. By lamination, the layer structure 1 can be applied to the substrate layer 12 to form the element 2.

In addition, FIG. 12 shows the arrangement of the partially interrupted decorative layer 7 on the film layer 3. In the exemplary embodiment shown in FIG. 12, it is provided that the printed image is formed in a mirror-inverted manner. For better comprehension of the layer structure 1, individual, associated layers are shown pulled apart. The embodiment shown in FIG. 12 is suitable for the application area of wallpapers, decorative papers, decorative films and edging material in the form of a prefabricated composite film for lamination on a substrate layer 12 and / or a carrier layer 5. It is not shown that a metal layer 4 is on the metal layer 4 , preferably translucently colored, lacquer layer can be applied as a protective layer 8 in order to change the color of the metal. In principle, the metal layer 4 can also be applied on the top side of the film layer 3, facing the user side 6. The top layer of the top protective layer 8 is designed as a transparent surface finish, which has a further layer on the underside. The film layer 3 can be formed as a transparent plastic layer, for example as a transparent printing film, in particular comprising polypropylene, PVC and / or PET. The color ink absorption layer 1 1 serves as an adhesion-promoting layer. The decorative layer 7 is printed on the underside of the film layer 3. Another film layer 3, which is designed as a transparent or transparently colored or pigmented plastic film, is used as a carrier layer 5 for the metal layer 4. The film layer 3, to which the metal layer 4 has been applied, can have a plastic, such as polypropylene, PET, PETP, PVC, PEN, PEEK, PE and / or PI. Aluminum is provided as the material of the metal layer 4 in the exemplary embodiment shown in FIG. 12, which has been applied to the underside of the film layer 3. A further protective layer 8 is provided on the underside of the metal layer and is designed as a lacquer or plastic film layer. The layer structure 1 can be laminated to the base layer 12.

Fig. 13 shows a multi-layer structure 1, which is intended for use as a flexible furniture and / or covering film, that is to say for use for a furniture and / or covering element for the floor, wall or ceiling. In the embodiment shown in FIG. 13, the metal layer 4 is applied on the underside, facing away from the usage side 6, on the carrier layer 5. A transparent PP film and / or PET film can be used as the carrier layer 5, which is colored and / or pigmented if necessary. Different metal tones can be achieved in this way. The use of a transparent and / or translucent carrier layer 5 offers the advantage that the film side - if the carrier layer 5 is formed as a film - serves as a wear layer, protective layer 8 and / or printing layer and protects the metallization from abrasion and moisture, since the Metal layer 4 is located on the back of the carrier layer 5 formed as a film.

The interrupted decorative layer 7 can be printed directly onto the film surface of the carrier layer 5, a print being provided in the exemplary embodiment shown in FIG. 13 on a color ink receiving layer 11 formed as an adhesion-promoting layer. To protect the metal layer 4, a protective layer 8 is provided on the underside, facing away from the user side 6. The protective layer 8 can be formed in the form of a lacquer, film coating and / or Ka schierung. Furthermore, the protective layer 8 compensates for any unevenness in the substrate layer 12, in particular the surface of an HDF or MDF board. The protective layer 8 can also be designed as a damping layer 9.

In principle, the finest bumps in the micrograph on the surface of the underlayer 12 on the composite film, that is to say through the multilayer layer structure 1, can be telegraphed so that the bumps are also visually recognizable on the user side 6 of the layer structure 1. This can lead to undesired visual impairments, such as the orange skin effect, lead. In order to counteract this, a protective layer 8 designed as a damping layer 9 can be provided. A thermoplastic wear layer can be provided as the top-side film layer 3 - which in this case forms the wear layer - as a transparent single or multi-layer top layer. In the embodiment shown in FIG. 13, advantageous materials for the film layer 3 would be, for example, TPU, PET and / or PP and / or a molten polymer layer, in particular comprising PP and / or PE and / or polyolefins. A molten polymer layer offers the advantage that, if the plastic has not yet hardened, a surface structure can be embossed into the surface by means of an embossing calender, for example a pore pore or brush structure. In the exemplary embodiment shown in FIG. 13, the layer thickness of the multilayer layer structure 1 is between 350 μm to 500 μm. The layer thickness of the film layer 3 is between 200 to 500 μm.

The use of PET, PP, PE polyolefins, TPU and / or PET as the material for the film layer 3, which is designed as a plastic film, is particularly environmentally friendly because these plastics do not contain PVC, chlorine or plasticizers or other harmful substances.
