Decorative film

 

The invention relates to a decorative film. Decorative film has a layered structure of at least two layers. Layers include, for example, a transparent base film, covered on one side with a reflective layer. The protective layer can protect the reflective layer from external influences. Facing the reflecting layer forming the surface of the base film is obtained by forming the structure of groups of geometric shapes. Occupied by the group surface has a width of 30-300 μm. Formed in the base film, the elements of the group are mainly rectangular cross-section, and occupied by the group surface consists of elemental surfaces lying in a plane parallel to the molding surface, and remaining in the plane forming the surface of the residual surfaces. Occupied by groups of surfaces separated areas of the background field in the plane of the molding surface. The technical result - the creation of effective, high quality decorative film having similar mirror reflecting property and it is difficult faked imperceptible signs of authenticity. 2 C. and 20 C.p. f-crystals, 9 Il.

The invention relates to a decorative blankenau packaging products and/or to protect products from counterfeiting, if, for aesthetic or economic reasons cannot use protective items, such as colorful holograms, mosaic with diffraction gratings, etc.

Decorative film of the above described kind is known from WO 82/03202. Paper base with one hand plastificator to smooth the surface. Then smooth the surface metallizer by deposition of aluminum so that the polymeric layer is concluded between the metal layer and paper. This decorative film can be processed as paper, and it has on one outer side of the metal appearance. Metallic outer side can be further overprint.

In EP 0209362 A2 describes a decorative film, in which the first on both sides of the polymer film is applied a metal layer, and one side has sertalinehealthy surface, and the other side is a matte surface. High-gloss or matte surface of the polymer film laminated to paper. Additional printed on the metal layer lacquer coating causes increased resistance of the metal layer to abrasion. Decorative film can be processed as paper, and do you print on the metal side.

Famous is tirovannoj foils for hot stamping with the make a photocopy of the document by using the illumination in the area of the metallized film for hot stamping could clearly identify as a fake.

These decorative films with mirror Shine are sold free and they do not have a sign indicating the manufacturer of the product.

Later in the EP 0132668 B1 mentioned laminated metal foil or covered with tiny metal flakes of paper, which can also be embossed. Due to its suitability for cutting and folding with high speed such metallized paper is used, for example, in the tobacco industry as a packaging material.

For banknotes or passports, as it is known, for example from DD 228669 A5, on a substrate by gravure printing ink or a metal paste is applied relief patterns. Formed by the relief structures of the latent image can be discerned only when the specified condition consideration. In US-PS 5772248 disclosed embossing in foil of such visible to the naked eye latent image.

The basis of the invention lies in the task of creating effective, high quality decorative film, which would be similar to a mirror reflecting property and difficult to support the signs, given in the characterizing portion p. 1 formula. The preferred implementation of the invention are given in the dependent clauses.

Decorative film comprises at least two layers of a base film coated on one side of the reflective layer. A reflective layer is, however, preferably between the base film and the protective layer. Facing the reflecting layer forming the surface of the base film contains obtained by molding the structure of groups of geometric shapes. Occupied by the group surface has a width of 30-300 μm. Formed in the base film, the elements of the group are mainly rectangular cross-section, and occupied by the group surface consists of elemental surfaces lying in a plane parallel to the molding surface, and residual surfaces in the plane of the molding surface. Occupied by the group surface separated areas of the background field in the plane of the molding surface.

Examples of execution of the invention depicted in the drawings and described in more detail below. In the drawings shown:

In Fig.1 POS.1 denotes a decorative film, 2 is a base film, 3 - reflecting layer 4 and protective layer 5 - base layer 6 forming the layer 7 forming the surface of the base film 2, 8 - plane, parallel to the molding surface 1, 9-11 - cell surface lying in parallel planes 8. On the molding surface 7 deposited reflective layer 3. Both depicted in Fig.1 decorative film 1 different base film 2; execute left is equipped with a massive base film 2, whereas the execution right of the base film 2 is a laminate 12 is formed from a base layer 5, the molding layer 6 and the possible, not shown here, the layers between the base layer 5 and the molding layer 6. The reflecting layer 3 is indicated in Fig.1 to the left in the form of a “layer” dual line and to the right and then a thick line. Molding surface 7 of the base film 2 is structured by forming elements 14 matrix 15 so that the elements 14 part reflecting layer 3 with the molding surface 7 as elemental surfaces 9-11 locally displaced almost the Nate 12) due to the molding elements 14, is deepening, for example, generally rectangular cross-section. In the first execution of coming into contact with the reflective layer 3 of the surface of the image sensor 15 is polished. The size And elemental surfaces 9-11 range from 250 nm to 300 μm, i.e., can be created education with a resolution of 4000 pixels/mm or 100000 dpi. Sign decorative film 1 is exaltation in the form of cylinders, prisms, truncated cones, pyramids, etc., with cell surfaces 9-11 as covering surfaces. Cell surface 9-11 have as a limit the outlines of geometric shapes, such as letters, figures, design marks, logos, etc. and made in the form of elevations above the molding surface 7, for example, in the form of text.

Lots of structured reflective layer 3 of a thickness of several microns mostly covered with a protective layer 4, so that the reflective layer 3 was located between the base film 2 and the protective layer 4 is protected from external influences. The reflecting layer 3 can be seen through the base film 2 and/or the protective layer. It manifests itself in the form of a cast metallic mirror surface, if the material of the reflective layer 3 is a metal (Al, Ad, AI, SG, si, Fe, Ni, Pd, Ti, and so on). If the reflective layer 3 , 1.8 for light in the visible range, the decorative film 1, in General, transparent, transparent base film 2 and the protective layer 4.

Lots of decorative film 1, but in which the incident light and the direction of the review meet the condition of reflection, Shine like a mirror; it creates a particularly decorative effect. Formed in the reflective layer 3 structure discernible in detail only with the aid of a strong magnifying glass. As cell surface 9-11, and residual surface 13 between the offset height of the element surfaces 9-11 are presented to the observer evenly light, however reflective side surfaces of the structures do not meet the same condition considering that cell surface 9-11 and residual surface 13, and presented so with less brightness than the elemental surface 9-11 and residual surface 13. On the edges of the element surfaces 9-11 arise in addition, the effects of scattering, so that the contours of the elemental surfaces 9-11 compared to cell surfaces 9-11 and residual surfaces 13 stand out so clearly distinguishable introduced by the structure of information (text, graphics, logo, trademark, etc).

Packing with a decorative film 1 is preferred and the decorative film 1 gives an indication of authenticity of the original product, the study, which may be held at any time and everywhere without opening the package. For a buyer this packaging reduces the risk of accidentally purchasing a fake, and the seller is negligent proposals forgery. Small additional costs of packaging to protect the same manufacturer of the original product from financial losses due to counterfeiting.

The base film 2 is either a massive thermoplastic film or laminate 12, at least two layers, for example the base layer 5 and is firmly connected with the base layer 5 a thermoplastic molding layer 6. The base layer 5 is, for example, of thermoplastic film or paper. The molding layer 6 is applied in the form of varnish on the base layers 5 or cacheroot in the form of a thermoplastic film on the base layer 5. Between the base layer 5 and the molding layer 6 can be enhancing the adhesion layers (“primer”), which prevents delamination of the laminate 12. The base film 2 is mainly transparent, if it forms the outer side of the decorative film 1, and it may be colorless (transparent as glass”) or painted. If the protective layer 4 is transparent and forms the outer side of the decorative film 1, the base film II WO 82/03202 laminate 12, containing paper as the base layer 5. The base layer 5 consists of a cardboard or paper, called below “paper”, which in a specified sequence, caused on the one hand possible, which increases the adhesion of the intermediate layers 16 and the polymeric layer 17 (polyolefin, polyester, PVC and so on). Polymer layer 17 can be used directly instead of forming the layer 6 matrix 15 (Fig.1). In another implementation, on the polymer layer 17 may be additionally caused is shown in Fig.2, the dashed line forming layer 6. Based on the laminate 12 with the base layer 5 of the paper decorative film 1 are used mainly in the packaging industry, as this special decorative film 1 has the advantage that it, like paper, can be processed at high speed. If the paper has a quality cardboard, decorative film 1 can be used, for example, for the manufacture of decorative boxes. Decorative film 1 with a thin piece of paper (weight per square meter 17-80 g/m2) is used, for example, as a decorative facing boxes, etc.,

Thermoplastic film to the base film 2 (Fig.1) or to the base layer 5 is preferably of polyester (politico, suitable for the production of polymer films. Especially polyester film are without staining transparent as glass, and with a small thickness have high tensile strength as required for the packaging material. Staining of the polymer causes partial transparency of the film for a limited part of the visible spectrum; it is transparent in decorative (e.g., red) color. In accordance with the application of the decorative film 1, the thickness of thermoplastic film has a value between several micrometers and several millimeters, mostly, however, 5-100 microns.

Possible forming layer 6 is applied usually in the form of a varnish. Proven transparent varnishes on nitrocellulose and/or acrylate-based (for example, polymethylmethacrylate, PMMA) or one of varnishes, cured by UV radiation. Forming the layer 6 may be, however, duplicated on the base layer 5 in the form of a thin film of polyvinyl chloride (PVC), PET, PC or PP. The undeformed thickness of the molding layer 6 reaches at least a distance d, mainly forming layer 6 deposited on several microns in thickness, so that the structure is entirely contained in the molding layer 6.

According to EP 0386316 A1 the rollers. On the matrix roller mounted matrix sleeve having on its outer side surface of the negative patterns being formed. In Fig.3 shows a fragment of the side surface of the matrix 15 matrix sleeve. The side surface has a surface structure consisting of, for example, evenly spaced groups of elements 14 (Fig.1). Between groups of elements 14 are free fields 18. The side surface consists, therefore, of occupied fields 18 of the surfaces of the background and a group of surfaces 19, and group surface 19 formed residual surfaces 13 and punched surfaces 20-22 elements 14. Surface fields 18 and residual surface 13 to form a matrix surface 23, which defines the plane molding surface 7. Chisel surface 20-22 form total area, which is less than 20% of the lateral surface is smaller than the area of the matrix surface 23 on the side surface. The surface structure of the matrix 15 can be sublime or profound; for example, in the implementation depicted on the right chisel surfaces 20, 21, towering above the matrix surface 23, while in the execution left punched surface 22 are recesses in the matrix is the d and punched surface 22 is at a different distance due to the molding elements 14 in the base film 2 (Fig.1.) or in the laminate 12 (Fig.2) create cavities, mainly rectangular cross-section. With the advantage of better molding elements are slightly narrowing to chisel surfaces 20-22 so that the recesses have a trapezoidal cross-section. Cell surface 9-11 (Fig.1) and the residual surface 13 (Fig.1) we have after forming the base film 2 fine structure respectively punched surfaces 20-22 and matrix surface 23.

A common way of forming structures of the matrix 15 in thermoplastic film is heated embossing matrix 15. Matrix 15 heats the surface of thermoplastic film so that the elements 14 penetrate into the surface of the film and move the element surface 9-11 elements 14 in a parallel plane 8 (Fig.1) on the distance d. The distance d has a value in the range of 0.05-10 μm. Preferred values of d is 0.1-2 μm. In another way the structure of the matrix 15 is formed in the surface of the varnish, UV curable by radiation. In this method, a reflective layer 3 (Fig.1) is applied after forming the structure of the matrix 15.

As shown in Fig.4, a protective layer 4 covers the page is on nitrocellulose and/or acrylate base. Recesses in the base film 2 is completely filled and leveled. The thickness of the layer, measured above the plane of the molding surface 7 has a value in the range of 0.5-10 μm. The formed structure is entirely covered with a protective layer 4 in order to prevent direct access to structured now forming surface 7. If the protective layer 4 above the reflective layer 3 must be especially resistant to scratching, it is recommended that one of varnishes, UV curable by radiation, used to protect exposed to high loads surfaces of credit cards, identity cards with IP and etc.

In fulfilling the left in Fig.4 formed in the base film 2 structure has a deepening of trapezoidal cross-section. The condition for the consideration of this structure is less constrained than the structures of rectangular cross-section. Very fine structures, for example, a double line in the implementation of the right rectangular cross-section can be formed unclean and have rounded edges. If the decorative film 1 must be connected to the substrate 24, a protective layer 4 is made for connection with the substrate 24; or facing away from the reflective layer 3, the surface of the protective layer 4 caused an additional adhesive layer 25 (the indicators are as cold-setting adhesives, for example, based on rubber, and adhesives hot curing. The latter develop their adhesive properties only at elevated temperature, for example, hot curing adhesive based on polymethylmethacrylate, starting with approximately 110C. the Thickness of the adhesive layer 25 or with adhesive ability of the protective layer 4 depends on the roughness of the surface of the substrate 24 and the material type of glue. Glue cold curing has a thickness of about 10 μm for a smooth and up to 30 µm for rough surface of the substrate 24. For material thickness of the glue hot enough curing of about 1 μm for a smooth and up to 10 µm for rough surface of the substrate 24. The adhesive layer 25 or with adhesive ability of the protective layer 4 on the basis of cold-setting glue is covered with easily removable protective film 26 made of polyester or impregnated with silicone paper to prevent unwanted adhesion of the decorative film 1. Before attaching the decorative film 1 to the substrate 24 and the protective film 26 is removed.

Decorative film 1 can be cut into narrow strips or brand 27 a few square centimeters, as shown in Fig.4 by broken lines. Transfer ribbon 28 facilitates PR the water tape 28 with the base film 2 is performed through the separation layer 29, for example, wax, and is easily removed after gluing marks 27 on the substrate 24. The manufacture of decorative film 1 comes from the base film 2, which is connected with a bill of tape 28. After applying the last layer, i.e., the adhesive layer 25 or with adhesive ability of the protective layer 4 or the protective film 26, 27 brand hew out of the decorative film 1 from the last layer in the direction of translation of the tape 28, not cutting it (“kiss-cut”). After gluing marks 27 on the substrate 24 pass-through tape 28 is removed (Fig.4 right). Documents, banknotes, identity cards of any kind, etc. acquire by such marks of 27 simple protection from Photocopying and structure in the decorative film 1 forms at the same time easy to verify the characteristic of the brand 27.

In Fig.5 when viewed from above, shows a fragment of the decorative film 1 with a group of 30 elemental surfaces 9-11 and residual surface 13 within the group of the surface 19. Group surface 19 is a used to napisanie fictitious rectangle that each party is concerned, at least one of the elemental surfaces 9-11. Group surface 19 is surrounded by fields 18, separating from each other group 30. Elemental surface of the corresponding group, the distance d. When the light falling on the edges of the element surfaces 9-11 experiencing the effects of scattering so that the contours of the elemental surfaces 9-11 with the aid of a magnifying device visible as a contrast the contrast of the surrounding space. If the elemental surface 9-11, residual surface 13 and fields 18 are mirror, the image in Fig.5 are outlined with black edge of the letters correspond to the contrast caused by the differences between the contours. The appearance of the elemental surfaces 9-11 enhanced by the selection shown in Fig.4 trapezoidal cross-section structures or by restricting the structure of double edges. When considering the naked eye decorative film 1 emits a metallic luster and is indistinguishable from unstructured metallized film. The group sizes of the surface 19, is shown in Fig.5 as an example, approximately 340 μm in length and 75 μm in width, and contour lines of the elemental surfaces 9-11 were taken with a width of up to 15 μm. To information “TEXT” was a good read, the size of the group surface 19 should accordingly be selected taking into account prescribed for control of the decorative film 1 magnifying device, and set uvlechennogo glass is less than the usual 30 cm, well distinguishable so-called “microeconomy” letters, signs, etc. height of 30-300 μm.

In Fig.6 depicts a segment of a decorative film 1. On the entire surface of the decorative film 1 group 30 are arranged with equal intervals and separated by zones not occupied by groups of 30 surfaces background of the field 31. One of the groups 30 depicts viewed through the magnifying glass 32. With a strong increase can see the outline of the elemental surfaces 9-11. The density of groups 30 of the decorative film 1 depends on the application and the length of the group 30. The proportion of elemental surfaces 9-11 in the surface of the decorative film 1 is less than 20%, mainly 1-10%.

Known optically variable diffraction image in the form of holograms and technology “Kinegram” according to EP 0105099 B1. Diffraction images have often mirrored surface. As an extra sign of security they have, instead of the mirror surfaces plots with group images 30 and the background field 31.

Group 30 in the implementation of Fig.7 are arranged in series in the form of text strips 33. For further text-decoration strip 33 is framed by narrow lines 34 or double lines 35 a width of 0.05 mm or less. For example, the surface lines 34 or double lines 35 on the technology gives the stamp of 27 visible to the naked eye optically variable figure 36 Giosa diameter of the order of several centimeters and are distinguishable only by looking through a magnifying glass 32. This brand 27 due to the mirror effect suitable as copy protection and pasted as a sign of authenticity on the substrate 24 (document, ID, card, etc).

In Fig.8 shows the performance of a decorative film 1 with an optional printed on the base film 2 markings 37 (text, images, logos, etc). Run to the left contains the markings only 37 facing away from the reflective layer 3 to the outer side of the base film 2, and the implementation of right - on both sides of the base film 2. The numbering of the base film 2, at least one of both sides of the information or instructions may contribute data about the origin or decor decorative film 1. Marks 37 are protected from abrasion, if they are printed on the inside, facing away from the reflective layer 3 side of the base film 2.

Is depicted in Fig.8 the structure of the decorative film 1 requires for forming the matrix 15 (Fig.3), punched surface 20-22 (Fig.3) and/or matrix surface 23 (Fig.3) we have instead of the mirror-smooth surface of the microscopically fine relief structure 38 or 39, which, when the molding is transmitted to the cell surface 9-11 or on the background surface is from CH-PS 653782 structure “of cinema form”. Cell surface 9-11 (Fig.1) have at least within the same group 30 (Fig.6) the same relief structure 38. The next group 30 may vary differently oriented relief structures 38, so that in one direction distinguishable first microeconomy, and after turning the decorative film 1 in the other direction to read the second microeconomy. The difference in height within the relief structure 38 or 39 is in the range 10-5000 nm.

Isotropic Matt structure diffuse the incident light regardless of the direction of his fall evenly across the half-space above the Mat structure (isotropic). The surface of the decorative film 1 is covered with an isotropic Matt structure has a matte black glitter. Anisotropic Matt structure is in the same orientation relative to the incident light matte appearance; in a different orientation after rotation Mat structure around an axis perpendicular to its plane, matte structure glitters, but this gloss is much weaker than the intensity of light adjacent the mirror surface. Elemental surface 9 of the whole group 30 have the same matte structure. The next group 30 may vary differently oriented anisotrop what Rast, and the second microeconomy with low contrast relative to the background field 31 (Fig.6), and in the other direction first microeconomy has a low contrast, and the second microeconomy - high contrast.

Matrix surface 23 or punched surface 20-22 may also contain hidden information, provided for this purpose special relief structure 39 and are used in combination with a mirror surface for chisel surfaces 20-22 or matrix surface 23 for forming patterns of the decorative film 1. This formed the base film 2 relief structure scatters the incident incoherently light in normal lighting conditions similar to matte structure, so when considering using a magnifying glass 32 (Fig.7) cell surface 9-11 appear to be either a mirrored surface on the metallic matte background field 31 or matte shimmering metallic surface on a mirrored background field 31.

In Fig.9 shows a fragment of the decorative film 1 with a special relief structure 39 (Fig.8). When illuminated with a parallel coherent light beam 40 of the laser diode or laser 41 special relief structure 39 deflects the incident coherent light so that the rejected Sweeney 1 screen 43. Representative of these special relief structures 39 is “cinema form, created with the help of a computer hologram. Hidden information to reconstruct a coherent light regardless of what place “kinoform” lit or how large illuminated surface, however, the quality of the image projected information worsens the more, the less illuminated surface. This behavior is also known from Fourier holograms, in which each surface element contains all the visual information of the hologram. In a real implementation “kinoform” calculated using the computer, the relief profile is repeated on cell surfaces 9-11 (Fig.5) or on the background field 31 (Fig.6) in a uniform raster field 44 which have typical sizes in the range of 0.5-10 mm, while the parts are designed relief profile is divided raster field raster elements 45, typical sizes are in the range of micrometers, mainly in the range of 0.5-5 μm. For lighting use source 41 of the laser light, the parallel light beam 40 which creates a decorative film 1 spot light, fully illuminating for good quality images, at least one raster floor is eminii decorative film 1 by a laser beam is reconstructed on the screen is not ideal, if the surface proportion of all microeconomic is less than 5% of the surface of the decorative film 1. Large mirrored the proportion of the background field 31 results on the screen 43 to a bright specular reflection, in which hidden information is hardly distinguishable. In addition, microeconomy acts as a mask imposed on the cinema form”. This mask arise diffraction effects which drawing is superimposed on the reconstructed logo 42 and additionally lubricates it.

Preferably is selected when the execution of the decorative film 1, which has all the background field 31 is covered raster fields 44 “kinoform”, and the element surface 9-11 microeconomic have a mirror structure. The observer sees the naked eye shot with hints of metallic luster decorative film 1, which is indistinguishable from a smooth film. Check with a magnifying glass 32 (Fig.7) under oblique lighting reveals micromarketing. Hidden information is visible only on the screen 43, if the decorative film 1 to cover the coherent light.
