Definitions
- the invention relates to a method for producing a security paper, which has the following steps: providing a flatly extended substrate which has a front and a rear side, applying a transit element to the front side, which is bounded by at least one edge, and Application of a stabilizing coating to the rear side in a section of the substrate which covers the transfer element in plan view.
- the invention further relates to a security paper which has: a planar substrate with a front and a back, a transfer element on the front that is delimited by at least one edge, and a stabilizing coating on the back in a section of the substrate, which covers the transfer element in plan view.
- WO 2011/015622 A1 describes a generic method for producing a security paper and a security paper.
- EP 1727684 B2 discloses a security and / or value document.
- WO 2004/024464 A1 relates to a reinforced security document. Further security elements and manufacturing processes for this are known from EP 2411232 B1 and EP 2860040 B1.
- the invention is based on the object of improving a substrate paper when a transfer element is provided. This applies in particular to forgery-proof and processability.
- a flat substrate is provided in the manufacturing process.
- the substrate has a front side and a rear side.
- the terms "front” and “back” are used here only to distinguish and are not intended to mean any preference for one of the two main sides of the substrate.
- a transfer element is applied to the front side of the substrate.
- the transfer element has at least one edge that lies within the longitudinal extent of the substrate, that is, does not coincide with an edge of the substrate.
- a stabilizing layer is applied to the opposite back.
- the stabilization coating is applied to the rear side in a section of the substrate in such a way that it covers the transfer element in the plan view of the substrate.
- the section of the substrate thus also covers the transfer element, in particular its edge.
- the section also has at least two surface sections. On these in the surface sections, the stabilization coating is configured in different ways, namely with different coating materials. The stabilization coating therefore has a different perceptible or measurable appearance on the two surface sections from the rear.
- the term "appearance” refers to how the stabilization coating can be perceived or perceived by the viewer from the rear can be measured by machine, in particular machine-readable. Perception should take place optically, ie through observation. The perceptible difference is in the range of the visible spectrum and is clear enough to be perceived by the viewer. The different appearances can alternatively or additionally be measurable by machine. The difference is preferably machine-readable or, more preferably, only machine-readable (that is, imperceptible). The measurable difference is adapted to be measured automatically by a machine (machine-readable). For example, a different infrared property, magnetic property, etc. of the stabilization coating can be measured automatically.
- the stabilization layer improves the processability and flatness of the security substrate obtained in this way with subsequent processes, in particular with intaglio printing. This is surprising insofar as it initially appears counterproductive to generate an additional thickening by the stabilizing coating in the area of the transfer element, which already results in a thickening of the substrate. However, it has surprisingly been found that the stabilization coating improves the flatness and processability of the substrate paper.
- the stabilizing coating preferably extends - as seen in plan view of the flat substrate - up to the edge of the transfer element, in particular it can cover it. It is optionally not applied over the full area to the rear side of the substrate, for example it delimits an inner part of the transfer element in plan view. However, the stabilization coating is preferably provided over the entire surface of the two surface sections of the substrate. It is sufficient in embodiments to cover or cover only the edge of the transfer element in such a way that (only) one strip is covered on both sides of the edge. If the transfer element is designed as an elongated strip which extends over a longitudinal extent of the security substrate, the transfer element consequently only has two edges within the relevant section of the substrate.
- the stabilizing coating can then have the form of two strips, each of which covers an edge. If, on the other hand, the transfer element is designed as a so-called "patch", the stabilization coating can be designed in the form of a frame, the frame width and dimensions being selected so that the edge of the patch is covered. In other embodiments, the stabilization coating completely covers the transfer element and is slightly larger , so that a strip beyond the edge of the transfer element is also covered.
- the stabilizing coating does not cover the entire surface of the rear side of the substrate, but only protrudes over the edge of the transfer element by the strip already mentioned
- the width of this overhang is preferably not more than 10 mm, particularly preferably not more than 5 mm, very particularly preferably it is in the range between 2 mm and 4 mm.
- the surface sections of the substrate have the stabilizing coating due to printing or coating with the different coating materials.
- the stabilization coating is thus applied by printing or coating.
- coatings that differ in appearance but have the same stabilizing effect are preferably applied in the two surface sections.
- the stabilization coating has at least one first coating section and at least one second coating section.
- the first coating section lies in the first surface section and the second coating section in the second surface section.
- a multiplicity of first or second coating sections can lie in the first and / or the second surface section.
- the first (s) and second (s) coating sections differ in their appearance, for example in the perceptible color.
- the first (s) and second (s) coating sections however, have the same stabilizing effect, that is to say in particular also the same layer thickness.
- the coating sections in their surface section are preferably spaced apart from one another and alternatively applied adjacent to one another.
- coating sections of the first surface section are preferably applied at a distance from coating sections of the second surface section.
- the coating sections are preferably applied over the entire area.
- the coating is then continuous in the coating sections.
- Coating sections applied over part of the surface are conceivable.
- a grid or a network could be used as a partial-area coating section.
- the area coverage of the coating in the sub-area coating sections will be greater than 30%, preferably greater than 50%, but less than 75%.
- the relative area coverage of the stabilizing coating on the substrate is considered, it is above 50%, preferably above of 66% and more preferably above 75% and in each of the cases further preferably below 98%.
- the coating sections are preferably formed over the entire area. If all of the full-surface coating sections are arranged without any gaps, the relative area coverage is 100%.
- the coating sections are designed over the entire surface and spaced apart from one another.
- Lacquers in particular, particularly UV-curing lacquers can be used as the stabilizing coating.
- the stabilization coating is a non-self-supporting (carrier-free) layer. In contrast to a film-based transfer element, it cannot, for example, span a window in the substrate.
- the stabilization coating ensures that deformation of the substrate paper, for example formation of grooves or bulging, is significantly reduced or prevented, particularly in the case of further moisturizing, as is done in intaglio printing.
- the stabilization coating affects the substrate paper in the sheet during further processing of the sheet. However, it also improves the flatness of the individual bank notes, that is to say improves their further processing or handling, for example in bank note checking devices, bank note sorting devices or bank note counting devices. This is a first effect of the stabilization coating.
- the hurdle for counterfeiting is increased by the stabilization coating with at least two distinguishable surface sections, since additional security features are applied to the substrate with the aid of the respective surface sections of the stabilization coating.
- the substrate only optionally has no opening in the section, ie it is continuous and the front side and the rear side are uninterrupted in this area.
- the stabilization coating has the property known in the prior art that the processability of the substrate is not impaired by the transfer element, e.g. with regard to flatness etc.
- the stabilization coating has a uniform layer thickness, in particular because it is intended to develop a uniform stabilizing effect.
- the stabilization coating, the surface sections and / or the coating sections can have an independent surface shape.
- the independent surface shape can be designed as a pattern, symbol or sign. A surface shape is considered to be independent if it does not correspond to the surface shape of the transfer element - possibly minus an optionally available window.
- the stabilization coating itself can, for example, have a different surface shape (oval, circular, symbol-like ...) than the transfer element (rectangular, oval, circular, ). Due to the stabilizing function, however, the approximate size and surface shape of the stabilizing coating is partly given by the transfer element. However, one is much more flexible in the selection of the surface shape with the surface sections and / or the coating sections. These can be selected independently of the transfer element. Thus, in further refinements, for example, coating sections with a constant, independent surface shape could also be used for different transfer elements.
- At least one of the two different coating materials can comprise an additive which has the corresponding true causes decent or machine readable appearance.
- the stabilizing coating preferably comprises a first additive on the first surface sections and a second additive on the second surface sections.
- the stabilization coating can comprise the same ingredients on the two surface sections - apart from perceptible or machine-readable additives.
- the different appearance of the stabilizing coating on the two surface sections of the substrate is preferably produced by different additives.
- the additives can be perceived by the observer or can be recognized by machine.
- Particularly suitable additives are: colorants, such as dyes or color pigments; optically variable pig ments, such as interference layer pigments or liquid crystal pigments; magnetically alignable (optionally optically variable) pigments; luminescent substances that emit, for example, after excitation in the UV / IR or VIS range in the same range or in a different range; Invisible additives, in particular additives that can only be detected in the UV or IR range, magnetic additives or additives that increase conductivity. Such additives are well known in and of themselves.
- the stabilizing coating is preferably cut on the two surfaces (or in their coating sections) - apart from the additives - uniformly formed. It comprises the same ingredients on both surface sections (or in their coating sections) and thus the same stabilizing effect.
- the additives are particularly preferably of the same type of additive.
- At least one surface section is printed with optically variable and / or luminescent coating materials.
- at least one of the surface sections photochromic and / or thermochromic beschich tet. All these design options for the surface sections of the stabilizing coating increase the number of security features of the substrate, which means that the hurdle for forgery can be raised further.
- Each substrate can contain one or more of the mentioned additives in a surface section of the stabilization coating. Before given, different colorants are used as additives on the two surface sections or different photochromic or thermochromic additives are used on the two surface sections. Alternatively, a colorant can be present on the first surface section and a photochromic or thermochromic additive can be present on the second surface section.
- the stabilizing coating preferably has a covering surface, with at least 80% - preferably 100% - area coverage. In this case, it is preferably present with a precise fit with the transfer element.
- the surface sections (or the coating sections) can - for example alternately - be arranged in such a way that a machine-recognizable code is created, in particular an IR code, a magnetic code or a conductivity code.
- the transfer element can have its own carrier layer, in particular carrier film. Alternatively, the transfer element is carrier-free, that is to say has no carrier layer of its own, such as carrier film. In a known manner, the transfer element - with or without its own carrier film - is transferred as an element from an intermediate carrier to the substrate when it is applied to the substrate.
- the substrate is designed in such a way that it has a window (or an opening).
- the transfer element spans the window. This feature also helps to stabilize and increase the counterfeit hurdle.
- the coating can be applied before or after the window is introduced into the substrate.
- At least one further printing element is applied to a different location on the substrate in the same printing cycle with the stabilizing coating. This supplements the substrate with additional security features and also enables the production process of the substrate to be accelerated. It should be noted that a printing element under or over a stabilization layer does not form a distinguishable stabilization coating.
- the stabilization coating improves the mechanical properties, such as tensile strength and / or flexural rigidity, of the security paper in the section.
- the tensile strength and / or the flexural strength of the safety paper in the section is preferably increased by at least 2%, preferably at least 4%, further preferably at least 5%, by the stabilizing coating. In particular, the increase is a maximum of 50%, generally less than 25%.
- the security paper with substrate and transfer element is measured before and after the stabilization coating is applied.
- the tensile strength and / or the flexural strength of the stabilizing coating is in preferred embodiments in the range from 25% to 150%, preferably 33% to 99%, more preferably 33% to 75% of the tensile strength or flexural strength of the transfer element.
- the mechanical property, such as tensile strength and / or flexural strength, of the stabilization coating is at least 1.1 times greater, preferably at least 1.5 times greater, than a substrate layer of the same thickness in further configurations.
- the maximum factor in each case is 5. The values mentioned can advantageously be used in combination with one another.
- a security paper which has a flatly extended substrate which has a front and a back.
- a transfer element which is delimited by at least one edge, is applied to the front.
- a stabilization coating is applied to the rear side in a section of the substrate.
- the transfer element is covered by the stabilization coating on the rear side in the plan view.
- at least two surface sections of the substrate are printed or coated differently by the stabilizing coating.
- the security paper can be used in particular to produce a security document, in particular a bank note. Such a security document is therefore also provided.

- a strip-shaped primer 12 is first applied, onto which the strip-shaped transfer element 6 is applied.
- the strip-shaped transfer element 6 comprises optically or otherwise recognizable security features which improve the security against forgery of the utility 2 or of a bank note produced therewith.
- the strip-shaped transfer element can comprise a film as a carrier or can be carrier-free. It can be carried out continuously, but also include a recess.
- 2A shows a window 13 which is formed in the substrate. The window 13 is closed before given to the transfer element 6. It would be conceivable that the transfer element also has a window 13 which is located either over a sub strate section without a window or congruently over the window of the sub strate.
- the transfer elements also shows the individual panel 2 of the banknote paper 1 with a view of the front side 11.
- a patch-shaped primer 14 is first applied to the front side 11, to which the patch-shaped transfer element 9 is applied.

- the coating sections are designed as longitudinal strips (FIG. 5A) or as transverse strips (FIG. 5B).
- a machine-readable IR code is applied with the aid of the different surface sections 17 and 18, as shown in FIG. 5C.
- the coating sections 17, 18 are applied as patterns, ornaments and / or characters, as in FIGS. 5D-F and 5 HL.
- the strip-shaped stabilizing coating is shown with gradual color tones, as shown in FIG. 5G.
- tonal motifs 19 and watermarks 20 (FIG. 5H), further printing elements 21 (FIG.
- the coating sections ie the stabilization coating 7, are preferably produced by a printing process and the additional printing elements mentioned are applied to the substrate back 15 in the same printing process as the stabilization coating 7.
- FIG. 6 shows a section through the panel 2 in a further embodiment.
- the two coating sections 17, 18 of the stabilizing coating 7 overlap. This creates an overlapping area 24. This is possible in a similar manner with a patch-shaped application area 8.
- This overlap area of the two coating sections 17, 18 of the stabilizing coating increases the stability of the panel 2 again, while at the same time making it more attractive with further security features through the possible variations of the coating sections 17, 18 described in the previous figures, and at the same time the forgery hurdle is further increased.
- exemplary embodiments with two coating sections 17, 18 on two corresponding surface sections of the section of the substrate have been described.
- Embodiments are not restricted to this, rather a multiplicity of coating sections can be used.
- individual coating sections in the form of a pixel can be used to create a multitone or colored image. be designed.
- the coating sections or the surface sections do not have to directly adjoin one another; Gaps are possible. Even then, the stabilizing coating still has a sufficient effect for better processability of the substrate.
