Definitions
- the invention relates to a method for producing a security paper, which has the following steps: providing a flatly extended substrate that is continuous in at least one section and there has an uninterrupted front and an uninterrupted rear side, and applying a stabilizing coating in the section on the Back.
- the invention further relates to a security paper which has: a flatly extended substrate which is continuous in at least one section and there has an uninterrupted front and an uninterrupted rear side, and a stabilizing coating applied in the section on the rear side.
- a generic manufacturing method and a generic security paper are known from WO 2014/095039 A1. It provides a stabilizing coating for a continuous, i.e. windowless arch.
- the stabilization coating is designed as the strips running around the edge of the sheet. It can be provided on the front and / or back and is intended to improve the behavior of the sheet without openings in printing processes.
- EP 2461970 B1 describes a production method for a security paper and a security paper obtainable therewith, a window opening being seen which is covered by a film.
- a stabilizing coating is provided around this opening for stabilization.
- the invention is based on the object of improving the processability of an opening-free substrate paper when a transfer element is provided on the front side.
- the invention is defined in the independent claims. The dependent claims relate to preferred developments.
- a flat substrate is provided.
- the substrate has no opening in at least one section, ie it is continuous and has an uninterrupted front side and an uninterrupted rear side in this section.
- front side and rear side 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 carrierless transfer element is applied to the front of the substrate. Carrierless transfer elements do not have their own carrier layer, that is to say, in particular, no separate film layer.
- the transfer element is located in the section of the substrate in which it has no opening.
- the transfer element has at least one edge which lies within (the extent) of the substrate, that is to say does not coincide with an edge of the substrate.
- a stabilizing layer is applied to the opposite rear side.
- the processability and flatness of the security substrate obtained in this way are improved by the stabilization layer.
- the flatness is improved after subsequent processes, in particular intaglio printing. This is surprising insofar as it initially appears counterproductive to generate an additional thickening by the stabilization coating in the area of the transfer element, which in itself has a thickening of the substrate. Nevertheless, it has surprisingly been found that the stabilization coating improves the flatness and processability of the substrate paper.
- the stabilization coating is only applied locally, i.e. not on the entire rear side of the substrate. It is therefore also referred to as a local stabilization coating.
- the stabilization coating is arranged in particular adapted to the edge of the transfer element.
- the stabilizing coating is preferably present continuously or in sections. It can cover the surface of the transfer element either continuously or in sections and / or extend either continuously or in sections beyond the edge of the transfer element.
- a continuous coating can also be referred to as a full-surface coating. In particular, it therefore has no interruption or recess. If, on the other hand, the coating has one (or more) recess (s), it is present in sections. If the coating has one or more interruptions, it is also present in sections - with several sections. Sections are in turn designed over the full area. In this paragraph and in all of the following, information always relates to a plan view of the flat substrate, unless otherwise explicitly stated otherwise. If the stabilization coating is present throughout, a distinction can essentially be made between three variants.
- the stabilization area Layering 100% of the area of the transfer element and extends beyond the edge of the transfer element.
- the stabilization coating covers more than 66% and less than 98%, preferably less than 95%, more preferably less than 90%, of the area of the transfer element.
- the stabilization coating exactly covers the transfer element (100%). It then only extends to the edge of the transfer element.
- the stabilization coating covers the edge of the transfer element as well as at least one strip-shaped portion each on both sides of the edge, as seen from above on the flat substrate. If a continuous stabilizing coating extends beyond the edge of the transfer element, a strip of the rear side of the substrate is covered — which adjoins the peripheral edge of the transfer element and encloses the transfer element. In the designs, the stabilization coating covers the entire surface of the transfer element. The stabilization coating thus completely covers the transfer element and is designed somewhat larger, so that a strip (or strip-shaped portion) beyond the edge of the transfer element is also covered. As already stated, the stabilization coating does not cover the back of the entire substrate. Rather, the stabilization coating only projects over the edge by the strip mentioned.
- the width of the strip (or 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 1 mm and 5 mm or 1 mm and 2.5 mm .
- the stabilization coating is present in sections, the following variants can essentially be distinguished: - With exactly one section for a circumferential outer edge of the Trans ferriis, or
- the stabilization coating preferably completely covers the edge of the transfer element, in particular as a continuous stabilization coating or as a stabilization coating with exactly one section for the circumferential edge or for each edge of the transfer element.
- the transfer element can be designed as an elongated transfer strip which extends over a longitudinal extension of the security substrate, the transfer element consequently has two edges within the relevant section of the substrate.
- the stabilizing coating can then have the form of two strip-shaped sections, 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 only the edge of the patch is covered on both sides.
- the stabilization coating covers less than 95%, preferably less than 66%, more preferably less than 33% of the area of the transfer element. In particular, between 5% and 66%, preferably between 5% and 33%, of the area of the transfer element are covered.
- the stabilization coating which is only applied on both sides of the edge covers a strip, in particular has a width (frame width or strip width of the two sections) of less than 20 mm, preferably less than 10 mm, particularly preferably the width is between 2 and 10 mm or 2 and 5 mm.
- the stabilization coating comprises a plurality of sections which are in particular arranged at a distance from one another.
- the sections preferably cover less than 95%, in particular less than 90%, of the area of the transfer element, more preferably more than 50% of the area.
- the stabilization coating is present continuously (or over the entire area) within the sections.
- a networked arrangement of the sections is conceivable in which the sections are connected to one another in places.
- the sections have an external shape such as a rectangle, square, oval or triangle.
- the sections have their maximum size (such as length, width, or diameter) in one direction. This maximum size of the sections only preferably corresponds to the corresponding size (i.e. length / width / ...) of the entire coating. If a transfer element has its maximum extension in a first direction (such as length or width), the maximum size of the sections is preferably in a second direction (such as width or length) which is at an angle of more than 60 degrees, preferably more than 75 degrees, particularly preferably orthogonal (with 90 degrees), to the first direction. In other words, the sections are preferably arranged in their forward direction perpendicular to the preferred direction of the transfer element.
- the several sections can be formed by sections with the same maximum size and / or the same external shape.
- the sections can, for example, be uniformly rectangular or square.
- the maxi- The size (or size) of the sections is preferably the same.
- the sections can be present as rectangles (or squares) of uniform size.
- the several sections can be formed by sections with the same maximum size and different external shape.
- the sections can be arranged as uniformly large but differently oriented equilateral triangles or acute triangles, rectangles or ovals.
- the sections can differ in their maximum size with the same external shape. Uniform shaped sections, such as rectangles or triangles, can have different first and second maximum sizes. Ultimately, both the outer shape and the maximum size of the first sections and second sections can differ.
- the sections preferably extend with a size which is between 75% and 200% of the corresponding (local) size of the transfer element. Such sections can be referred to as resized sections. In a first variant, the size is between 75% and 95% of the corresponding size of the transfer element. The sections therefore preferably end before the edge of the transfer element. Alternatively, the length of the sections is between 95% and 105% of the corresponding (local) size of the transfer element. The sections then end near the edge.
- the sections of the stabilizing coating extend with a length between 105% and 200%, preferably 110% to 175%, of the corresponding size of the transfer element. The stabilization coating covers - as always seen in plan view - with its sections the edge section by section (no longer completely).
- the sections are each smaller than 1% of the surface of the transfer element and / or do not extend in any direction device with more than 33%, in particular more than 20%, more preferably more than 10%, of the corresponding size of the transfer element.
- Such sections can be used as size-independent, not dependent on the size of the transfer element, sections.
- the stabilizing coating advantageously extends with less than 50%, preferably less than 33%, of the area of the transfer element beyond the edge of the transfer element.
- the stabilization coating (in any direction) advantageously does not extend beyond the edge of the transfer element by more than 10 mm, more preferably not more than 5 mm, particularly preferably in the range between 1 mm and 5 mm, very particularly preferably between 1 mm and 2, 5 mm.
- the stabilizing coating is a non-self-supporting layer for which lacquers in particular, especially UV-curing lacquers, can be used. Water-based paint systems are possible.
- the stabilizing coating is colorless and optionally, with regard to its matting, is matched to the gloss of the substrate paper after the engraving.
- the stabilization coating preferably comprises only a single layer and only alternatively exactly two sub-layers lying one above the other.
- the stabilizing coating can contain a matting agent, a luminescent substance and / or an effect pigment.
- the addition of UV absorbers is possible in order to simplify the monitoring during the application of the stabilizing coating and to prevent yellowing.
- a lacquer can also contain pearlescent pigments as effect pigments.
- the lacquer can also contain a dye or a luminescent substance.
- the stabilization coating also ensures that, in particular in intaglio printing, deformation of the substrate paper, for example the formation of grooves or bulging, is significantly reduced or prevented.
- the stabilizing coating preferably not only has a direct mechanically stabilizing effect, but also prevents moisture from penetrating into the substrate. The stabilization coating thus also ensures that deformation of the security paper is prevented or reduced, particularly in the case of rewetting or further processing.
- the coating agents mentioned in EP 2461970 B1 for another application are suitable.
- the stabilization coating can be applied by a printing process, in particular by gravure, flexographic, screen, offset or transfer printing.
- the transfer element is preferably a carrierless transfer element.
- Carrier-free transfer elements which in particular do not include a film of their own, are known and are generally detached from a temporary transfer carrier when they are transferred to the substrate.
- transfer strips and transfer patches are known as transfer elements.
- a transfer strip extends completely over the substrate in one direction. Accordingly, a transfer strip has two edges (in the present sense).
- a transfer patch is arranged inside the substrate and thus has a circumferential edge.
- a transfer patch can comprise a central recess and thus additionally have an inner edge.
- an edge of the transfer element which lies within the substrate, is an edge in the present sense.
- Substrate extends on both sides of the edge.
- the edge could also be referred to as the inner edge of the transfer element.
- Security paper is present as a security paper web or as a security paper sheet, it includes a large number of individual uses for security documents.
- a certain first number, for example 4-8, of individual copies lie next to one another in the width of the web on the security paper web. In the length of the web, however, there are any number of individual uses, in particular a second number of several hundred or several thousand individual uses in a row.
- On the security paper sheet there are a certain first number, for example 4-8, of single copies next to one another in the width of the sheet and a certain second number, for example 5-10, of single copies one behind the other in the length of the sheet.
- Each individual use has at least one of the named sections of the substrate with one of the named covered transfer elements, in particular with at least one covered transfer patch per individual use and / or a covered transfer strip section - a transfer strip of the security paper web or security paper sheet - per one to use.
- the security paper web / sheet can also include an outer area in addition to a central area with the individual copies.
- a strip-shaped transfer patch, which forms a transfer strip section for each of the individual copies, can be used in the outer area, i.e. within the Substrates, end. After the central area has been divided into individual uses, the outer area, which is only used temporarily, is usually disposed of.
- the stabilizing coating is first applied and optionally actively cured, for example by means of UV, IR and / or electron irradiation and / or heating, and then the transfer element is applied.
- the stabilization coating can thus already have a positive effect when the transfer element is applied.
- the stabilization coating can also be applied after the transfer element has been applied.
- the transfer element is attached to the substrate during application by means of an adhesive layer, preferably a thermally activatable adhesive layer.
- an adhesion-promoting layer such as a primer layer, is applied (in the transfer area) before the transfer element is applied.
- the adhesive layer lies between the substrate and the adhesive layer with which the transfer element is attached to the substrate.
- the invention is also directed to a security paper which has a flatly extending substrate which is continuous in at least one section and there has an uninterrupted front and an uninterrupted back.
- a stabilizing coating is applied to the back of the section.
- Also located in the section on the front side is a transfer element which has at least one edge that lies within the extent of the substrate.
- the stabilization coating covers more than 50%, but preferably less, when viewed from above on the flat substrate than 98% of the area of the transfer element, and / or extends - seen in plan view of the flat substrate - beyond the edge of the transfer element.
- the substrate can be a single-layer or multi-layer substrate. It is preferably a paper substrate.
- the substrate can be provided with a plastic film, in particular after the steps mentioned.
- Any type of paper can be used as paper, in particular made of cotton.
- paper can also be used which contains a proportion of plastic material, for example a polymer material.
- 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 the subject of the invention according to an independent claim. The invention is explained in more detail below using exemplary embodiments with reference to the accompanying drawings, which also disclose features essential to the invention. These exemplary embodiments are for illustrative purposes only and are not to be construed as restrictive.
- FIG. 1 shows a schematic representation of a security paper with two transfer elements which function as security features
- FIG. 2 shows a sectional illustration through the security paper in the area of one of these transfer elements
- FIG. 3 shows a schematic view similar to FIG. 1 to clarify the relative position of a stabilizing coating and the transfer elements
- Fig. 4 is a further schematic view to illustrate the relative position of Re another embodiment of the Stabilticiansbe coating and the transfer elements and
- FIGS. 2 and 3 representations similar to FIGS. 2 and 3 for a modified embodiment.
- the security paper 2 comprises two transfer elements, namely a strip-shaped transfer element 4 and a patch-shaped transfer element 6. These transfer elements are applied to a main side of the security paper 2. They each include at least one optically or otherwise recognizable security feature that improves the security against forgery of the security paper 2 or the bank note. In the present case, a transfer element is used which is free of its own carrier layer.
- a security paper can be present as a sheet or web and later divided into its individual uses, such as banknotes, with only one of the individual uses being considered in the figures.
- the two transfer elements 4, 6 are shown in order to make it clear that the embodiments can be used equally for different transfer elements.
- the present solutions can be used in particular for continuous strips as transfer elements which have exactly two edges, such as the elongated transfer element 4, or also for patch-shaped transfer elements 6 which have a circumferential edge.
- FIG. 2 schematically shows a sectional illustration through the security paper 2 in the area of one of the transfer elements. It is not relevant here which of the transfer elements 4, 6 is shown, since the principles explained apply equally to both.
- the security paper 2 has a substrate 8 which has no breakthrough opening, ie no window, in at least one section 10, ie has a continuous front side 12 and a continuous rear side 14 in this section 10. Of course, this does not preclude the substrate 8 from having windows in other sections.
- the transfer element here designated by the reference number 16, is applied to the front side 12. It has at least one edge 18 at which the transfer element 16 ends, but the underlying sub strate 8 continues along its surface extension. The transfer element 16 thus has an extension that covers a first area 20.
- a stabilization coating 22 is applied to the opposite rear side 14, which covers a second area 24 on the rear side 14, which is larger than the first area 20.
- the stabilization coating 22 is thus in plan view (for example in FIG above) beyond the edge 18.
- the stabilizing coating 22 also covers the edge 18 in the top view and also covers a strip on this side of the edge 18, that is to say within the transfer element 16 - again seen in the above-mentioned plan view.
- the second area 24, ie the extent of the stabilizing coating 22, is greater overall than the first area 20, that is to say the extent of the transfer element 16.
- the overlap that is achieved by is shown in Fig. 3, which shows the mentioned plan view schematically.
- the stabilization coating 22 is shown in dashed lines with regard to its outline. As can be seen, it covers the transfer element in plan view, both when this is designed as a strip-shaped transfer element 4 and when it is designed as a patch-shaped transfer element 6.
- the stabilization coating 22 covers the transfer element 16 over the entire area.
- 4 shows a plan view of an embodiment in which the stabilization coating 22 comprises a plurality of sections 42. The sections 42 are arranged at a preferably regular distance from one another. The surface of the transfer element is therefore no longer completely covered by the stabilizing layer, but only with a percentage, for example 90%.
- the widths of the sections 42 arranged under the transfer strip 4 are adapted to the width of the transfer strip 4. They extend in their catches over the width of the transfer strip and in the example shown in turn extend beyond the transfer strip, for example between 10% and 100% longer than the width of the transfer strip.
- the sections 42 need not be oriented in any particular direction. For example, they can also run at an angle of 45 or 60 (instead of 90) degrees to the transfer strip 4. However, the sections 42 each extend at least over 75% of the corresponding size of the transfer strip (in this direction and at this point). Irregularly wide transfer strips 4 are, for example, conceivable and known.
- the transfer patch 6 shown now also has a central recess in FIG. 4, so that it has an outer edge and an inner edge.
- the - now annular - surface of the transfer patch 6 is more than 75% covered by the sections 42 of the local stabilization coating 22.
- the width of the sections 42 can be seen from the local width of the Transfer patches 6 adapted.
- the height of the sections 42 is greater than their distance, in particular greater than 2 mm.
- the sections 42 are arranged in such a way that the edge of the transfer element is well covered, proportionally more than 66%, preferably more than 75%. The effect of the chosen arrangement is particularly easy to understand using the example of the inner edge, because a different arrangement could clearly lead to the majority of the inner edge being uncovered.
- each of the sections 42 - as in the configurations described above - the stabilization coating is present throughout.
- the sections 42 are shown in Fig. 4 as rectangular sections, but can also be designed differently, only for example rounded and / or with a wave-shaped contour.
- a rectangular section 42 can be formed, for example, by two partial rectangles of different sizes (two thirds of the length / one third of the length) or by two or more complementary triangles (separation of the shown rectangle along its diagonal). Spaced from sections are shown, with sections optionally also being able to be connected to one another in places. Further conceivable configurations with sections of the same or different sizes and / or the same and / or different external shapes are not shown separately in the figures.
- the edge 18 is covered by a strip which not only covers the edge 18 itself, but also the strip 26 on the other side of the edge 18, as well a strip, preferably of the same size, on this side of the edge 18.
- FIG. 5 again shows a cross section.
- the stabilization coating 28 is present in a certain width under the edge 18, but not under the entire transfer element 16.
- the stabilization S istsbe Anlagenung 28 is then, as the plan view in Fig. 6 shows, for example frame-shaped (in the case of the patch-shaped transfer element 6) or in the form of two strips, so formed from two sections 28a, 28b, as is the case for the strip-shaped transfer element 4 is illustrated in FIG. 6.
- the stabilization coating 22, 28, 28a, 28b is applied (and cured) in the production process before given to the application of the transfer element 16.
- the materials and application techniques used in the general part of the description can be used.
- stabilization coating 24 strips 42 sections of the stabilization coating
