Abstract

The invention relates to a security paper (14) for the production of security or valuable documents, having a first security element (20) running through the window area or through opening (12) of the security paper (14) and introduced during papermaking. According to the invention, the first security element (20) is combined with a second security element (22) applied to the security paper (14) after papermaking, which closes the window area or the continuous opening (12) and in the window area or in the area of the continuous one Opening (12) is at least partially transparent.

Description

  • The The invention relates to a security paper for security or value documents with a see-through area, so a window area or a through opening of the security paper, and one through the review area, in the papermaking introduced first security element.
  • Documents of value, such as banknotes, stocks, bonds, certificates, vouchers, checks, high-quality tickets, but also other forgery-prone papers, such as passports or other Identity documents are often provided with security elements for protection provided a review of the Allow the authenticity of the value document and at the same time as protection to prevent unauthorized reproduction.
  • there In particular, such security elements have been used in the past proven, the only while the manufacture can be introduced into the security paper, such as such as watermarks, chemically reactive additives or mottled fibers, or in the security paper completely or partially embedded security threads.
  • The Introduction of security threads in value documents has long been known. The width of However, less than 4 mm of relatively narrow threads are viewed by the viewer often hardly noticed. A completely embedded security thread with a typical width of 2 to 3 mm is considered in the Incident light can not be detected, but occurs only with transmitted light in appearance. The little threads can therefore by imitations, such as corresponding printing layers, Deposits and the like, are relatively easily imitated.
  • From that Based on the invention, the object, the disadvantages to avoid the prior art and in particular a security paper specify the type mentioned above with high security against counterfeiting.
  • These The object is achieved by the security paper having the features of the main claim solved. A method for producing such a security paper as well a corresponding value document are specified in the independent claims. Further developments of the invention are the subject of the dependent claims.
  • According to the invention is in a generic security paper the first security element with one after papermaking on the security paper applied second security element combined, which closes the window area or the continuous opening and in the window area or at least partially in the area of the through opening is transparent.
  • The first security element is preferably a film element which is advantageously provided with information in the form of patterns, characters or codes. As a film element, for example, a security thread or, with particular advantage, a wide security band into consideration. While security threads have a width of less than 4 mm, endless security elements with a width of 4 mm or more are referred to herein as security bands. The safety bands may in particular have a width of 4 mm to 20 mm, sometimes even up to 30 mm. The embedding of such security tapes in papermaking, for example, in the document EP 0625 431 described, the disclosure of which is included in the present application in this respect.
  • With Advantage is also the second security element a film element, this advantageously with information in the form of patterns, Characters or encodings is provided. The second security element For example, in the form of an elongated safety strip or a patch of any shape.
  • According to one particularly advantageous embodiment of the invention provide the first and second security elements in the pane or in the area the through opening related or complementary information. For example the information of the second security element may be the information repeat the first security element or for a total information complete.
  • In all variants of the invention are the information or information with advantage in a printing layer or a metallization layer on the first and / or second security element. The information) can in particular by reflective, magnetic, electrically conductive, phosphorescent, be formed fluorescent or other luminescent substances.
  • In an advantageous variant of the invention is the first security element wider than the window area or the through opening formed. The second security element is then advantageously narrower than the first security element and wider than the window area or the through opening educated.
  • In an alternative embodiment, the first security element is formed narrower than the window area or the through opening. The second security element is in this case expediently wider than the first security element and wider than the window region or the through opening.
  • The second security element may be the window area or the through opening both close one-sided as well as two-sided.
  • The combination according to the invention realizes in particular the following advantages:
    • The second security element applied after papermaking provides mechanical protection both for the window area or the through openings and for the first security element otherwise comparatively unprotected in this area.
    • The second security element draws the viewer's attention to the security element combination.
    • - The combination of the two security elements realizes a very high security against counterfeiting, especially when the two security elements contain related or complementary information.
  • The invention also includes a method for producing a security paper for security or value documents, in which
    • - a first security element is introduced into the security paper during papermaking,
    • - in the security paper during or after papermaking a see-through area in the form of a window area or a through opening is created, through which the first security element runs, and
    • - A see-through area is closed after papermaking by a second security element, which is at least partially transparent in the see-through area.
  • In an advantageous variant of the method is the window area or the through opening already produced in papermaking. Such, in the sheet formation generated openings have characteristic irregularities in the margins that are on the finished Paper later can not be produced. The irregularities are particularly evident by the lack of a sharp cutting edge or by irregular attachment of fibers in the edge region and by projecting into the opening of individual fibers.
  • To another, also advantageous variant is the window area or the through opening after paper production by cutting or punching with a sharp border area generated. For example, a spicy limited opening be produced by laser cutting, the edge surfaces thereby an appropriate choice of beam divergence and beam tilt in parallel and perpendicular to the paper surface or also against the surface normal can be inclined.
  • The Invention contains also a value document, such as a banknote, an identity card or the like with a security paper of the type described above.
  • Further embodiments as well as advantages of the invention are described below with reference to FIGS explained. For better clarity, the figures refer to a scale and proportionally true representation omitted.
  • It demonstrate:
  • 1 a schematic representation of a banknote according to an embodiment of the invention,
  • 2 a cross section through the banknote of 1 along the line II-II,
  • 3 in (a) the partial information of a film strip applied to a banknote according to the invention, wherein (a) simultaneously represents the image impression when the banknote is viewed in the background, (b) the partial information of an embedded security tape, and (c) the overall information which can be seen in a transparent manner,
  • 4 the image impression when viewing a document of value according to another embodiment of the invention, wherein (a) shows the image impression in review and (b) the image impression in supervision,
  • 5 a cross section through a banknote according to another embodiment of the invention.
  • The invention will now be explained in more detail using the example of a banknote. With reference to the 1 and 2 shows first 1 a schematic plan view of a banknote according to the invention 10 . 2 a cross section through the banknote 10 along the line II-II of 1 ,
  • In addition to other, known per se and therefore not shown in the figures elements, the banknote 10 in particular one through the banknote paper 14 through opening 12 on and two coordinated security elements 20 and 22 in the area of the opening 12 overlap.
  • The first security element is it is a wide security band 20 , that in the paper making so inside the banknote paper 14 it was embedded that through the opening 12 runs. The part of the security tape embedded in the banknote paper 20 is in 1 shown with dashed lines, while inside the opening 12 running part is shown hatched.
  • The second security element is only after paper production on the surface of the banknote paper 14 applied transparent film element 22 that the opening 12 of banknote paper 14 completely closes on its top. The foil element 22 can be used as a foil strip or, as in 1 , be designed as a patch of any shape.
  • The relative dimensions of the two security elements and the opening are chosen so that the film element 22 at its narrowest point at least 2 mm wider than the opening 12 , For example, the film element 22 in the embodiment of 1 and 2 at its narrowest point a diameter of 10 mm, while the opening 12 is square and has a side length of 8 mm. Also in other Gestal lines is the film element 22 Advantageously at least 1 to 2 mm wider than the opening 12 to completely close them.
  • The safety tape 20 is in the exemplary embodiment 6 mm wide and is thus much wider than conventional security threads whose width is typically only 2 to 3 mm. Despite its comparatively large width is the safety band 20 a few millimeters narrower than the opening 12 and therefore can be completely inside the opening 12 lie, as in the 1 and 2 illustrated.
  • The subsequently applied to the banknote foil element 22 now offers on the one hand an additional mechanical protection for the safety strap 20 and the opening 12 and, on the other hand, draws the observer's attention to the combination of the authenticity mark formed by the film element and the security tape. In addition, through the interaction of foil element 22 and safety tape 20 a particularly forgery-proof design of a mark of authenticity can be realized:
    The security band 20 and the film element 22 are in the area of the opening 12 each provided with mutually related partial information that complement each other when viewed in transmitted light to a complete overall information. This partial information may, for example, be in a printing layer or a metallization layer of the security tape 20 or of the film element 22 available.
  • Is a first piece of information on the security tape 20 and a second part information on the film element 22 before, so is when looking at the banknote 10 in supervision only the partial information of the film element 22 to recognize. Looking at the banknote 10 In transmitted light, the second part information of the safety band is additionally displayed 20 recognizable and complementary in the area of the opening 12 with the first part information for a total information.
  • 3 shows a concrete embodiment, wherein the applied after paper production on the banknote security element in the design of the 3 as a foil strip 32 is formed. In the area of the opening of the bill bears the foil strip 32 as partial information a section 34 a denomination of the banknote indicating number sequence "50", as in 3 (a) shown. A complementary section 36 the sequence of numbers is used as partial information on the security tape embedded in the banknote during papermaking 30 applied, as in 3 (b) shown.
  • When viewing the banknote in incident light for the viewer is only the partial information 34 of the applied foil strip 32 to recognize, so that under these viewing conditions a visual impression as in 3 (a) results.
  • On the other hand, if the banknote is viewed in transmitted light, the cut-outs are complementary 34 . 36 of the safety band 30 and the foil strip 32 to a total information 38 , so the viewer the in 3 (c) can perceive the full picture impression shown.
  • The partial information of the two security elements can, as in the embodiment of 3 to each other in the register. However, there are also unprepared embodiments possible, as based on 4 Illustrated: Also in this embodiment, the embedded security tape included 40 and the applied foil strip 42 complement each other de partial information 44 and 46 , where a perfect alignment of the two sub-information 44 . 46 for the recognizability of the overall information 48 is not required. Accordingly, the security band 40 and the applied foil strip 42 also be arranged offset in a document of value.
  • 4 (a) shows the visual image impression when looking at the value document in review, 4 (b) the image impression in supervision, whereby the unrecognizable partial information 46 of the safety band 40 indicated by dashed lines. As in the embodiment of 3 the incident light observation shows only the partial information 44 of the foil strip 42 while looking in the see-through the total information 48 both security elements 40 . 42 is recognizable. The number sequence "100" is clearly recognizable even without a passer between the two security elements.
  • Another variant of the invention is in 5 shown. In this variant of the invention is in a banknote substrate 50 with continuous opening 52 a safety tape 54 embedded, whose width is greater than the width of the opening 52 is. In the visible area in the opening, the security band 54 for example, be screen printed.
  • In the embodiment, the opening 52 on both sides of a subsequently applied film element 56 closed, wherein the width of the film element 56 in the design of 5 less than the width of the safety band 54 but 1 to 2 mm larger than the width of the opening 52 is selected.
  • In this case, the upper foil element 56 , the security band 54 and the lower film element 56 each contain different, mutually agreed partial information. For example, the two foil elements 56 crossed linear polarizers and the safety band 54 a piece of information printed with a phase-shifting material, such as a liquid crystal material. In transmitted light, the printed information lights up in the opening 52 then bright against the dark background of the crossed linear polarizers.
  • In Another variant is the top of the opening with a foil security element closed and the bottom of the embedded security element through a thin one Paper layer, a so-called Formerlage covered.
