Definitions
- the invention relates to a method for producing a security element, in which a first microstructure is produced on a front side and a reflector layer is applied over it.
- the invention relates to a security element which comprises a first structurable layer, which is applied on a front side, a first microstructure in a surface of the first structurable layer and a first reflector layer on the first microstructure.
- Such structures are known for reflective holograms. They use micro-optical effects for security elements and are usually produced by embossing a metal layer or by embossing and subsequent vapor deposition (PVD) of a metal layer on the embossed structure.
- the metal layer can be subsequently structured by laser ablation.
- the object of the invention is to provide a method for producing a security element and a security element, so that manufacturability, security against imitation and visual appearance are improved.
- the method for producing a security element comprises the following steps: providing a first structurable layer, producing a first microstructure in a front side of the first structurable layer, applying a first reflector layer to the first microstructure in a first pattern, which can be seen from the front side ,
- the first reflector layer is applied by printing in the first pattern with a homogeneous thickness.
- the first reflector layer is removed by means of laser ablation, wherein a second pattern, which can be seen in plan view of the front side, is produced in the first reflector layer.
- a first authenticating feature is the reflector layer in the first pattern.
- the first pattern preferably relates to an outline of the reflector layer, through which, for example, a geometric shape or a contour of a person or an object can be seen in plan view.
- the second authenticity feature is created by the removal of the first reflector layer to produce the second pattern, which can be seen in plan view.
- the second pattern may be a representation of the object or a geometry.
- the first pattern and the second pattern can complement each other to a total pattern.
- both authenticity features can be recognized by the naked eye for a viewer.
- Another advantage is the fact that the reflector layer thus has two optically effective (identically) microstructured surfaces. The microstructuring is effective as an authenticity feature in supervision from the front and also usable as an authenticity feature in supervision of the back.
- microstructures ie also the first microstructure, adapting pigment is designed to be so thin or flexible that it follows the contour of the microstructure.
- Such nanoparticles or contour-matching pigments are known, for example EP 1689586 B1 .
- WO 2010/069823 A1 and WO 2013/090983 A1 are known, for example EP 1689586 B1 .
- the microstructure is preferably produced by embossing.
- the first patternable layer is provided on a substrate.
- the structurable layer may alternatively itself be a substrate. These steps of the procedure need not be performed in the order given. It is also possible in further developments to produce the microstructure in a structurable layer and further optionally to transfer the thus structured layer onto the substrate.
- a substrate such as paper
- a substrate such as a foil
- a substrate such as paper
- a substrate such as a foil
- the security element may be a data carrier, such as a security thread, a label, a transfer element or a security print.
- the substrate may be configured as any thin-surface element suitable for supporting the first patternable layer and the first reflector layer.
- the substrate may be a paper, in particular a cotton paper, or a film of polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), polypropylene (PP) or polyamide (PA).
- the paper can be one Proportion x artificial polymer material in the range of 0 ⁇ x ⁇ 100 wt .-% included.
- the paper may also contain a proportion of other polymer material in the range of 0 ⁇ x ⁇ 100% by weight or consist entirely of synthetic polymer fibers, eg Tyvek®.
- the film may be monoaxially or biaxially stretched. It may also contain different polymer types, be coextruded and / or thermolaminated. Among other things, the stretching of the film leads to it obtaining polarizing properties which can be used as a further authenticity feature. For the utilization of these properties required tools, such. As polarizing filters are known in the art.
- the substrate can be a paper-foil composite or a film composite in which the substrate, the structurable layer and the reflector layer are embedded between two film layers.
- a front side of the patternable layer corresponds to a front side of the security element.
- the front side (or the back side) of the security element is to be understood in each case also in a plan view.
- This structurable layer then optionally comprises an embossing lacquer, for example a UV embossing lacquer.
- the patternable layer may also comprise any other material which is formable by temperature, pressure, printing, laser treatment or other types of treatment such that a microstructure can be produced therein.
- the structurable Layer can be transparent / translucent or opaque. It may also have a color which optionally does not interact with the laser radiation for laser ablation.
- the patternable layer is applied to the front side of the substrate, where the front side can be any side of the substrate and, alternatively, can also be referred to as a first side.
- the microstructure is optionally a hologram structure for generating a holographic image of an object or a person.
- the holographic image represents a further authenticity feature.
- a hologram for example a pictorial representation of an object or a person, can be seen in plan view.
- the microstructure may also be a microlens, micromirrors, or any other micron or nanometer scale structure.
- the microstructure may be, for example, by means of printing or laser ablation on the substrate, for. In the structurable layer. By applying the reflector layer to the microstructure, the latter is better in plan view or optically effective (eg in the case of a hologram).
- a second or third microstructure may also each be a structure with microlenses, micromirrors or any other structure that has an order of magnitude in the micrometer or nanometer range.
- the reflector layer may be greater than the microstructure in its surface extent in a preferred embodiment, so that the microstructure in a portion of the reflector layer is effective.
- the outline of the reflector layer is predetermined in the first pattern, which for example has a certain geometric shape or represents an object / person in cross-section.
- the first reflector layer is printed, taking care that their thickness is always the same, so that therefore results in a homogeneous thickness.
- the thickness is z. Along the local surface normal of the microstructure or along a normal to the plane in which the microstructure resides (eg, it may be an upper surface of the substrate).
- the surface structure of the security element is identical before the application of the first reflector layer and after the application of the first reflector layer, since the surface structure of the microstructure is retained by the first reflector layer due to its constant thickness.
- the microstructure is not equalized or filled by the printing. Due to this, the first microstructure can be seen from both sides of the reflector layer, i. H. in plan view of a front side of the security element and in view through a transparent portion through the substrate to the first microstructure and the first reflector layer.
- a metallic ink can be printed on the first microstructure by conventional printing methods, for example using known printing presses.
- the metallic ink may include metallic pigment particles and a binder.
- the metallic particles may be microstructured metallic flat pigments (flakes) comprising, for example, aluminum, stainless steel, gold, silver, platinum or copper.
- the binder of the metallic ink can be microcellulose, Vinyl chloride, vinyl acetate copolymers or vinyl included. Further, as metal particles for the metallic ink, silver nanoparticles, aluminum nanoparticles or titanium nanoparticles may be used.
- the second pattern is produced by partially or completely removing the thickness of the first reflector layer.
- the aim of this ablation is to increase the transmission of light in the ablated area compared to the rest of the first reflector layer, so that the second pattern can be seen in plan view and / or in review.
- the microstructure is not altered, i. H. not removed, so that the effectiveness of the microstructure and also the stability of the security element are retained.
- the first reflector layer has a homogeneous thickness and thus the intensity of the laser radiation can be adjusted so that only the first reflector layer is removed and the underlying microstructure or other layers are not damaged. Due to the fact that the first reflector layer has a constant thickness, the same laser power can always be used for the uniform removal of the first reflector layer. Furthermore, the microstructure may be opaque because, even if the laser ablation is operated with constant intensity, due to the homogeneous thickness of the first reflector layer, no damage to the microstructure is to be expected.
- the laser beam for laser ablation 2 laser having a wavelength of about 10.6 microns or Nd, for example, with an infrared laser, a CO: YAG laser with a wavelength of 1.064 microns are produced.
- the security element may be provided in the security element, such as an adhesive layer for securing a layer composite to the substrate, for example of a PU adhesive, or an intermediate layer, for example of a PET film.
- an adhesive layer for securing a layer composite to the substrate for example of a PU adhesive
- an intermediate layer for example of a PET film.
- the reflector layer can be covered with a cover layer of an optically transparent color or a transparent layer.
- the second pattern is optionally applied in such a way that it can be seen through.
- the substrate has a transparent or translucent section which is arranged below the structurable layer, wherein the first reflector layer is removed over the section, so that the second pattern can be seen through the section.
- the removed area of the reflector layer which can represent a recess in the first reflector layer, is illuminated in a transparent manner so that the second pattern is then particularly clearly visible. It also stands in perfect Passer to the first pattern.
- the first microstructure can be seen not only in supervision, but also in transparency.
- the transparent or translucent portion may be, for example, a window, an area in an opaque substrate in which a transparent or translucent portion is provided, or may be part of the transparent or translucent substrate.
- any portion of a transparent sheet may be considered the portion.
- opaque in the sense of the application is understood to mean a material which transmits a maximum of 5%, in particular a maximum of 2%, of the visible light.
- transparent or translucent in the sense of the application it is understood that a relevant material transmits between 50%, in particular 90%, and 100% of the visible light.
- a transparent and translucent material differs in that an image can be recognized through the transparent material - the image information remains after passing through the transparent material - this is not the case with a translucent material - the image information is lost through the translucent material.
- the section can also be made translucent in that, although the substrate is opaque, it is made so thin in the region of the section that light can translucently pass through the section.
- the section may be part of a watermark.
- a similar composite structure as on the front side is preferably applied to a rear side of the security element.
- the following steps are preferably carried out: generating a second microstructure on a back side of the substrate under a transparent or translucent section and printing a second reflector layer on the second microstructure of homogeneous thickness in a third pattern, which can be seen in plan view on the back, wherein laser ablation simultaneously removes the second reflector layer by passing the laser radiation through the section during laser ablation. Because the first reflector layer and the second reflector layer are removed by the same laser irradiation, the patterns in the first reflector layer and in the second reflector layer are exactly in register with one another.
- the third pattern in which the second reflector layer is applied, may be identical to the first pattern, so that a similar outline of the respective reflector layer can be seen on the front side and the rear side. However, it is also possible that the third pattern differs from the first pattern, so that different outlines of the respective reflector layer can be seen on the front and back.
- the material of the first reflector layer may be identical to that of the second reflector layer, but it is preferred that different materials are used for the first reflector layer and the second reflector layer, so that preferably different optical impressions result from the first and second reflector layer.
- the second microstructure may also be incorporated into a patternable layer, which is optionally applied to the backside of the substrate over the portion.
- the portion and / or structurable layers are / are made transparent such that during laser ablation, the first reflector layer and the second reflector layer are ablated by the same laser irradiation step by passing the laser radiation through the section.
- the laser radiation impinges perpendicular to the substrate, but it is also possible that the laser radiation is incident on the substrate at a different angle, in particular between ⁇ 30 ° and ⁇ 60 ° to the normal, so that the second pattern is viewed at an angle , which corresponds to the angle of incidence of the laser radiation during laser ablation, is visible.
- the first reflector layer and / or the second reflector layer be applied in such a way that the first reflector layer in the first pattern and / or the second reflector layer in the third pattern at least one recess / has. Since the section is transparent and / or translucent, in principle the first microstructure would be visible from the rear side due to its homogeneous thickness, and the second microstructure would also be visible from the front in a top view. However, since the reflector layers are opaque, this is not possible.
- the recesses are therefore provided in the first reflector layer and / or in the second reflector layer, so that the first microstructure can be seen through the recess in the second reflector layer in a plan view of the rear side and / or the second microstructure is viewed through the recess in plan view of the front side to recognize in the first reflector layer.
- a second hologram of the second microstructure can be seen in the first microstructure that can be seen on the front side.
- a hologram in the hologram can thus be seen in plan view.
- the application of the at least one recess in the first reflector layer and / or in the second reflector layer can take place during printing itself or subsequently by laser ablation. It is preferred that the first reflector layer and / or the second reflector layer is already printed with the recesses on the first structurable layer or the second structurable layer.
- a substrate with a transparent section As far as proceeding from or in the following, a substrate with a transparent section is assumed, the further elements and embodiments can be provided analogously for a transparent substrate.
- a transparent section can also be understood as meaning a section of the transparent substrate which is not covered by opaque layers.
- the second reflector layer generates in reflection one of the first reflector layer different optical impression.
- the color of the radiation reflected by the respective reflector layer may be different.
- different materials for the first and second reflector layer are printed.
- the respective holograms then show different colors in supervision, so that they are particularly clearly recognizable. By using different colors, a bimetal effect can be generated in the hologram in the hologram.
- the security against forgery of the security element can be further increased by carrying out the following steps: producing a third microstructure on the front side of the substrate over the section and printing a third reflector layer on the third microstructure with a homogeneous thickness in a fourth pattern, which is in a top view the front side is recognizable, wherein the laser ablation simultaneously removes the third reflector layer and wherein the first reflector layer and / or the third reflector layer is / is applied such that the first reflector layer in the first pattern and / or the second reflector layer in the fourth pattern at least one Have recess / has.
- the fourth pattern may be identical to the first pattern and / or the third pattern, however, it is preferred that the fourth pattern be different from the first pattern and / or the third pattern.
- the fourth pattern can serve as another authenticity feature.
- the recess in the first reflector layer and / or the third reflector layer, as described above, also generates a hologram in the hologram.
- the first reflector layer (together with the first structurable layer) is disposed between the third reflector layer (together with the third structurable layer) and the substrate.
- a hologram of the first microstructure is visible in the hologram of the third microstructure.
- a hologram of the third microstructure can be recognized due to the recesses in the first reflector layer in the hologram of the first microstructure.
- a particularly simple arrangement of the first reflector layer and the third reflector layer results when the first reflector layer is arranged between the first and the third microstructure.
- the first reflector layer is in direct contact with the first and the third microstructure. This results in a preferred construction of the security element, in which the first microstructure lies under the first reflector layer, which in turn is arranged under the third macrostructure, which in turn is arranged under the third reflector layer.
- the carrier layer can be, for example, a film, in particular a PET film, which for example has a thickness of 6 ⁇ m.
- the microstructures are attached to the carrier layer, wherein the respective reflector layers are in turn applied to the microstructures. The first reflector layer is thus facing the back and the third reflector layer of the front.
- a fourth reflector layer which generates in reflection one of the first reflector layer, the second reflector layer and / or the third reflector layer different optical impression, in regions over the first reflector layer, the second reflector layer and / or the third reflector layer is printed with a homogeneous thickness, wherein optionally during laser ablation, the fourth reflector layer is removed simultaneously.
- the fourth reflector layer can be printed on the first, the second, or the third reflector layer or on all reflector layers. Since the fourth reflector layer and the respective underlying reflector layer each have a homogeneous thickness, the surface of the fourth reflector layer has the same structure as the underlying microstructure. The microstructure can therefore be seen even when the fourth reflector layer is printed on top.
- the fourth reflector layer differs in reflection in each case from the reflector layer on which it is applied, in their optical impression.
- the fourth reflector layer differs from the reflector layer on which it is applied in its colored perception, so that bimetallic effects can be generated.
- the fourth reflector layer and / or in the first, second or third reflector layer are also provided at least one recesses, which can be introduced as described above.
