Definitions

  • the invention relates to a substrate for the production of securities or security paper and a security or security paper.
  • Substrates, and in particular polymer substrates, and securities or security papers of the type mentioned at the outset are usually used in order to increase the counterfeit security of securities or security papers, such as banknotes, ID cards, credit cards, ATM cards, tickets, etc.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide means by which securities or security papers, in particular polymer securities or polymer security papers, can be produced or designed with one or more highly forgery-proof security elements.
  • the invention relates to a substrate for producing securities or security papers, the substrate comprising a carrier layer, in particular a polymer carrier layer, and at least one security element, and the security element being applied to and/or in the carrier layer.
  • a primer is applied at least in sections to a first substrate side and/or a second substrate side of the substrate.
  • the primer is arranged at least in sections between the carrier layer and the security element and/or the primer covers the security element and/or the carrier layer at least in sections, with areas of the security element covered by the primer being less clearly visible than areas of the security element not covered by the primer and/or or as areas of the backing not covered by the primer.
  • the security element is formed with a partial, reflective layer that forms an image.
  • primer can describe a single layer as well as a composite or a layering of several layers. This can involve, for example, several layers or plies of the same type, but also several different layers.
  • a layer is applied to something
  • the phrase "a layer is applied to something" should be understood to mean that a layer can be applied directly, or that there is another or there may be several intermediate layers.
  • one or more intermediate layers can be arranged between the layers described in this document. It is therefore not absolutely necessary for the layers described to contact one another.
  • layer in this document is to be understood in such a way that a layer can also be made up of a number of sub-layers.
  • image can be any type of characters, letters, patterns, motifs, geometric figures, guilloches and lines.
  • the substrate according to the invention creates the possibility or basis for producing securities or security papers with one or more highly counterfeit-proof security elements.
  • a banknote manufacturer is thus provided with a starting material which is fundamentally like or similar to paper for paper banknotes is processable.
  • a banknote manufacturer can thus produce both paper banknotes and polymer banknotes, for example using the same machines or process steps, or using minor modifications. This brings advantages in terms of profitability of the entire production chain, while maintaining high product quality.
  • the security element(s) formed in or on the substrate ensures an additional degree of security against forgery, because the visibility of the security element(s) is reduced as a result of the primer applied.
  • Those areas on the first and/or on the second substrate side on or in which a security element covered with a primer is formed can be perceived less well or less clearly than those areas of the carrier layer with and/or without an overlying primer.
  • the primer which serves to cover the security element or elements, but can also enable a later, individual printing of the substrate by a banknote manufacturer, is applied at least in sections to the security element or elements and/or to the carrier layer, so that at least selected areas are covered and are at least less well visible or less clearly or less strongly contrasted.
  • Security elements can be designed, for example, as security threads, security strips and the like, with other advantageous types or configurations known to those skilled in the art also being conceivable.
  • the image formed by the partial, reflective layer can be in the form of a mosaic-like image.
  • the formation of security elements with a partial, reflective layer that forms a mosaic-like image for example from the EP1674286A1 known.
  • very realistic-looking, high-resolution and high-quality or detailed images such as in particular raster images from, for example, metalized pixels or raster points can be displayed, with areas with different optical densities also being able to be realized.
  • a corresponding security element is applied, for example as a thread, strip or as a transfer thread film in or on a substrate and accordingly overprinted over the whole area or also in certain areas with the primer, the image or security element is made into a shadow image or watermark, or perceived as such by an observer .
  • the primer acts like a clouding layer. Since different optical densities can sometimes also be achieved from different image areas, multi-level watermarks can be implemented.
  • the areas of the security element covered by the primer are not visible when viewed from above and are visible when viewed through, or that the areas of the security element covered by the primer are better visible when viewed through than when viewed from above.
  • This advantageous embodiment can make it easier for a user to check the authenticity of a banknote by holding it against the light or looking through it. In this way, a further contribution can be made to counterfeit security in banknotes. It may also be the case here that not the entire area of the security element covered by the primer is visible when viewed through, but only those parts or areas of the element which are formed with the partial, reflective and image-forming layer.
  • a partial metallization or also a partial HRI layer--ie a layer with a high refractive index ("high refractive index", HRI)--or the image formed thereby, in particular also a mosaic-like image, would be recognizable in transmitted light.
  • HRI refractive index
  • the layer can contain gaps in the form of characters, letters, patterns, motifs, geometric figures, guilloches and also lines.
  • the substrate can be either a polymer substrate or a paper substrate.
  • substrate or polymer substrate are used below in particular, although it may be appropriate instead of a polymer substrate to use a paper substrate.
  • a polymer substrate comprises a polymer carrier layer
  • a paper substrate comprises a paper carrier layer or a paper substrate is made from a cellulose fiber-based pulp.
  • the primer is arranged at least in sections between the carrier layer and the security element, it can also be advantageous if the security element and/or the carrier layer and/or the primer are at least partially covered with a cover layer. Areas of the security element covered by the cover layer can be less clearly visible than areas of the security element not covered by the cover layer and/or as areas of the carrier layer not covered by the cover layer and/or as areas of the primer not covered by the cover layer. Thus, optical effects can be achieved by overprinting selected areas--for example also in the course of banknote printing--and in particular a visibility contrast between areas with a cover layer and areas without a cover layer can be brought about. Such a further development can be useful in particular when using polymer substrates.
  • the primer is applied by means of a printing process.
  • a uniform and level primer or primer layer can be implemented in an economical manner. This can be advantageous in particular in the case of further processing of the substrate in the course of subsequent banknote printing and can contribute to a high product quality.
  • the primer it would also be conceivable and possibly advantageous for the primer to be applied by painting, dip coating, spray coating or roller coating. It is also conceivable to apply the primer using vacuum-based coating methods, such as plasma coating or PVD and CVD coating.
  • the primer is designed to be printable.
  • Good printability can be important in further processing of the substrate in the course of banknote printing and can sometimes enable a satisfactory or even high final quality of a security paper, in particular a polymer security paper or polymer security paper.
  • good printability of the Primer or the substrate have a positive effect on the longevity or resilience of a banknote.
  • good printability can be achieved by an even primer, or also by a structure that takes up a printing ink well, or by the material of the primer.
  • the primer completely covers the carrier layer and/or the security element.
  • the security element or elements are completely covered and are therefore not visible or only visible poorly or indistinctly when viewed from above.
  • the primer it is possible for the primer to partially cover the carrier layer and/or the security element.
  • Such areas of the security element or elements, which are not covered by the primer and are therefore visible when viewed from above, are often referred to in the industry as windows.
  • Security elements designed in this way in the form of a thread are often referred to as window threads.
  • Such windows can be designed both as so-called half windows and as full windows.
  • a half-window is a gap in the primer on just one side of the substrate, or on one side of the primer. If the primer is applied to both sides of the substrate and gaps are provided opposite or at least partially opposite or overlapping in the primer on both sides, this is referred to in technical jargon as a full window.
  • These windows can make it easier for a user to verify the authenticity of a bill in a simple and quick manner.
  • security against forgery can be improved because an exact positioning of windows makes it considerably more difficult for bank notes to be imitated or forged.
  • the security element can be designed as a security thread with a partial, reflective layer that forms an image, it being possible for the image to be formed multiple times or repeatedly on the thread.
  • the primer is partially applied or printed onto the security thread in accurate register, it may be that the repeating image is visible in the windows and in the overprinted ones or primed areas appears as a watermark. In this way, two security effects can be achieved at the same time with a single security element or thread.
  • the other part of the portrait can be in a bridge area, ie in an area covered by the primer.
  • the security feature or the partial, reflective and image-forming layer is produced in the course of a work or production step and is then partially covered by the primer, a very high-quality and therefore highly forgery-proof substrate can be produced.
  • the match that can be achieved between the two parts of the coherent picture or portrait is not subject to any register fluctuations.
  • the primer is designed to be diffusely scattering, in particular that the primer produces a white color impression in daylight.
  • This configuration can have a particularly positive effect on a bank note that can be produced from the substrate, since a white base layer or surface can enable motifs, numbers and the like to be subsequently printed or otherwise applied in a particularly high-quality manner.
  • Such layers or primers are also known as opacifying layers.

  • the carrier layer 2 and the primer 4 can comprise the same material, in particular the same cellulose fiber-based material.
  • the substrate 1 is a paper substrate.
  • the paper substrate can be produced from a pulp, ie from an aqueous suspension comprising a cellulose material, in one—preferably continuous—process step.
  • the carrier layer 2 can be produced, in which case the security element 3, for example in the form of a security thread, can be introduced or blown in and a primer 4 formed from the same pulp can be applied to this partially or over the entire surface.
  • the primer 4, which, like the carrier layer 2, can be formed from paper, can subsequently be printed in the course of banknote printing.
  • the image formed by the partial reflective layer which according to the example in figure 1 represents the number ten repeatedly, may be formed of pixels 10 which are of different sizes and shapes, wherein a pixel 10 may be formed by a continuous area of the partial, reflective and image-forming layer 7 and wherein the partial, reflective and the Image-forming layer 7 between two picture elements 10 can be interrupted.
  • the image formed by the partial, reflective layer 7 is in the form of a mosaic-like image. It may also be the case that image elements 10 of different sizes correspond to different mosaics of the mosaic-like image.
  • the areas interrupting the partial, reflective and image-forming layer 7 can be formed by removing the layer 7, in particular by demetallization.
  • the security element 3 can have one or more additional layers, which additional layers can include in particular protective lacquers, heat-sealing lacquers, adhesives, primers and/or foils.
  • the substrate 1 can also have one or more additional layers.
  • the security element 3 and/or the carrier layer 2 and/or the primer 4 has a cover layer are covered at least in sections, whereby areas of the security element 3 covered by the cover layer can be less clearly visible than areas of the security element 3 not covered by the cover layer and/or as areas of the carrier layer 2 not covered by the cover layer and/or than by the cover layer uncovered areas of the primer 4. This is particularly the case when the primer 4 is arranged at least in sections between the carrier layer 2 and the security element 3.
  • a security or security paper can be produced with at least one security element 3 comprising the substrate 1, wherein the substrate 1 is designed according to one of the claims.
  • the substrate 1 can be a polymer substrate or a paper substrate. In order to avoid unnecessary repetition, the detailed description in the figure 1 pointed out or referred to.
  • a further embodiment of the substrate 1 is shown in a plan view, in which in particular an area of a security paper or security paper that can be made from the substrate 1 is shown, which is marked by dashed lines.
  • a security element 3 in the form of a security thread is applied to the substrate 1 and repeatedly reproduces a motif in the form of a temple.
  • the security element 3 is formed with a partial, reflective layer 7 that forms an image.
  • the primer 4 covers the carrier layer 2 over the entire surface and the security element 3 partially. Where the security element 3 is partially covered by the primer 4, the motif or the temple shown appears as a watermark or silhouette.
  • the primer 4 is applied only to the first substrate side 5 .
  • the primer 4 was also applied to the second substrate side 6 at least applied in areas.
  • the security element 3 has one or more additional layers, which additional layers can include in particular protective lacquers, heat-sealing lacquers, adhesives, primers and/or foils.
  • additional layers can include in particular protective lacquers, heat-sealing lacquers, adhesives, primers and/or foils.
  • the image formed by the partial reflective layer 7 can be formed of image elements 10 which can be of different size and shape, where an image element 10 can be formed by a continuous area of the partial reflective layer 7 forming the image and wherein the partial, reflective and image-forming layer 7 can be interrupted between two image elements 10.
  • the image formed by the partial, reflective layer 7 is in the form of a mosaic-like image. It may also be the case that image elements 10 of different sizes correspond to different mosaics of the mosaic-like image.
  • the areas that interrupt the partial, reflective layer 7 that forms an image can be formed by removing the layer 7, in particular by demetallization.
  • the Figure 3A shows a longitudinal section through the security element 3 designed as a security thread. Those areas not covered by the primer 4 are designed as windows 12.
  • the Figure 3C shows a longitudinal section through the substrate 1 in that area which is formed without a security element 3, with the primer 4 covering the carrier layer 2 completely.
  • a section through the temple motif of the security element 3 is shown, with the primer 4 not covering the security element 3 here and thus a window 12 being formed. In that window 12 the temple motif can be seen as a raster image.
  • the temple motif can be seen here as a high-resolution silhouette or watermark.
  • the carrier layer 2 can have a thickness 8 of 5 ⁇ m to 700 ⁇ m, preferably from 30 ⁇ m to 150 ⁇ m, particularly preferably from 50 ⁇ m to 125 ⁇ m, in particular from 65 ⁇ m to 90 ⁇ m.
  • the primer 4 can have a thickness 9 of 1 ⁇ m to 60 ⁇ m, preferably from 5 ⁇ m to 50 ⁇ m, particularly preferably from 7 ⁇ m to 45 ⁇ m, in particular from 10 ⁇ m to 40 ⁇ m.
