Definitions

  • the invention relates to a security element and a valuable document comprising a security element.
  • the invention also relates to methods of manufacturing the security element and the valuable document.
  • the substrates may be provided with through-windows thereby allowing observation of a security feature located on the foil and arranged in the window.
  • EP 2 199 095 A2 discloses a method that involves providing a sheet-like substrate with a recess that is formed via an opening in the substrate, where the opening is closed by a film on two sides. Additional security features are formed, and a coating is applied on the film such that a part of the coating adjoins a contour in a custom-fit manner.
  • the contour defines a recessed region of the substrate from a region of the substrate surrounding the recess.
  • the film is printed using a printing ink by offset printing.
  • WO 99/37488 discloses a method of verifying the authenticity of a security document, the security document including a first at least partially transparent portion and an optical projection element within or superposed with the first at least partially transparent portion, the optical projection element acting to transform a light beam passing from a light beam source through said first at least partially transparent portion into a patterned beam of selected design, the method including the steps of: positioning the security document such that the light beam is transmitted through the first at least partially transparent portion and the patterned beam is projected onto a viewing surface, and verifying the presence of a patterned image by the impingement of the patterned beam on the viewing surface.
  • US 5,248,544 discloses a data carrier such as a paper of value or the like having an optically variable element, in particular a hologram, applied to the surface, and an additional printed pattern, applied in particular by steel intaglio printing, wherein the surface of the data carrier is smoother in the area of the optically variable element than in the remaining surface.
  • WO 03/053713 A1 discloses a security element for security papers, valuable documents, identity cards or the like that is self-supporting and provided with two different security features. Said security features are disposed on opposite sides of the security element, and at least one security feature is optically variable.
  • a security element for a valuable document comprises a substrate.
  • the substrate, or the plies of the substrate in case of a multi layer substrate may comprise cellulose fibers, particularly cotton fibers and/or organic synthetic fibers and/or mineral fibers.
  • the substrate can generally be fibrous as for example any paper-like substrate.
  • a first groove (or depression) is arranged on a first surface of the substrate, and a second groove (or depression) is arranged on a second surface of the substrate.
  • the second surface of the substrate is opposite to the first surface.
  • the first groove and the second groove face into opposite directions and away from the substrate.
  • the first groove and the second groove are aligned with each other such that the first groove and the second groove are at least substantially superposed. In other words, the two groves substantially coincide or overlap if they are viewed perpendicular to the surface of the substrate.
  • the security element comprises at least two elongate flat elements.
  • the elongate elements advantageously have defined and even thickness over their full length and width. They can be attached to the substrate or any ply of the substrate after the grooves in the substrate or in any ply of the substrate has been formed.
  • the elongate elements are a foil and advantageously in strip form or a flat element of small size, as for example a patch which is attached to the surface of the ply or substrate.
  • the elongate elements can advantageously be attached once the fibrous substrate or ply has dried, for example outside the papermaking machine production line.
  • the elongate elements are a first foil and a second foil.
  • the first foil front foil
  • the second foil reverse foil
  • the thickness of the first foil and the thickness of the second foil would contribute to the overall thickness of the foils and the substrate together.
  • the thickness of the first foil and the thickness of the second foil are only partially compensated by the dimensions of the first groove and the second groove.
  • a security element is provided that is based on a double groove - double foil concept which provides better quality of the security feature in terms of costs, durability, reproducibility and processability than the prior art and still has sufficient flatness.
  • the dimensions of the first groove and the second groove comprise the depth, the length and the width of the first groove and the second groove, respectively. This provides that the additional thickness of the first and second foil is compensated substantially or to a certain extent over the area of the first foil and the second foil.
  • the area of the foils or the grooves is the product of length and width.
  • the depth of the first groove is lower than the thickness of the first foil. This is based on the recognition that it is not necessary that the entire thickness of the first foil is compensated by the first groove. In other words, in an embodiment, the thickness of the first foil can therefore be greater than the depth of the first groove, for example by 5 ⁇ m to 35 ⁇ m.
  • the width and length of the first groove are advantageously dimensioned such that the first foil fits into the first groove.
  • the thickness of the second foil can also be greater than the depth of the second groove, for example by 5 ⁇ m to 20 ⁇ m. However, in an advantageous embodiment, the depth of the second groove can be about equal to the thickness of the second foil.
  • the present invention particularly applies to embodiments in which the width of the first groove, the width of the second groove, the width of the first foil and the width of the second foil are equal to or greater than 0.8 cm.
  • the width of the first groove can range from 0.8 cm to 3 cm.
  • the width of the second groove can also range from 0.8 cm to 3 cm.
  • the width of the first foil can range from 0.8 to 3 cm.
  • the width of the second foil can range from 1 cm to 4 cm. This implies that the width of the second foil can advantageously always be greater than the width of the second groove.
  • the width of the first foil can be equal to or lower than the width of the first groove.
  • the width of the first foil can, for example be slightly lower than the width of the first groove by 1 mm to 6 mm.
  • the thickness of the second foil is at least partially compensated by the second groove.
  • the depth of the second groove can be equal to or lower than the thickness of the second foil.
  • the width of the second foil can be equal to or greater than the width of the second groove.
  • the width of the second foil can, for example be greater than the width of the second groove by 1 to 4 mm.
  • the length of the second foil is advantageously equal to the length of the second groove.
  • the width of the second foil can be greater than the width of the first foil.
  • the second groove may inherently be a bit narrower than the first groove. It is then particularly advantageous that a certain overlap over the longitudinal edges of the second groove is acceptable.
  • banknotes undergo a huge number of processing steps from manufacturing until they are sorted out and destroyed, it has been found that the two foils do not need to be entirely embedded in the substrate.
  • a certain additional thickness or thickness variations are tolerable within the limits and definitions given in this specification.
  • the first and second grooves as well as the first and second foils extend over the full length or width of the valuable document.
  • the two grooves and the two foils of the security element typically all have the same length.
  • the length of the first foil can advantageously be equal to the length of the second foil and also the first groove and the second groove can have the same length.
  • the first and/or second foil advantageously have a width generally ranging between 8 mm and 30 mm, a thickness ranging between 10 ⁇ m and 50 ⁇ m, and a position from one edge to the opposite edge, across an entire length or an entire width of the substrate and therefore do not occupy the entire surface area of the substrate.
  • a layer of the substrate can remain between the first groove and the second groove over the major part of the area in which the first groove and the second groove are superposed. In other words, in the area where the first groove and the second groove are superposed, or coincide, the majority of the substrate is not removed.
  • the thickness of the remaining layer of the substrate in the area in which the first groove and the second groove are superposed can be 80 ⁇ m 130 ⁇ m. However, this value also depends on the overall thickness of the substrate. In terms of the reduction of the thickness of the substrate due to the first groove and the second groove, the reduction can range from 4 ⁇ m to 35 ⁇ m, and advantageously from 8 ⁇ m to 12 ⁇ m.
  • the security element can further comprise a window in the substrate in the area in which the first groove and the second groove are superposed. In the area of the window, the substrate is entirely removed.
  • the security element can further comprise a security feature that is arranged in the first foil and/or the second foil.
  • the security feature can advantageously have a visual effect.
  • the security feature in either the first and/or second foil can then advantageously be arranged in the window.
  • the security feature is located in the first foil, if the first foil is thicker than the second foil and does not overlap the first groove at the longitudinal edges of the first groove.
  • the substrate can be made of a single layer or ply. However, advantageously, the substrate can comprise a plurality of layers of plies. In an embodiment, the substrate may comprise a first ply (layer) of fabric and a second ply of fabric. The first ply and the second ply can extend over the entire substrate. In other words, the substrate can be formed of at least two plies, the first and the second ply.
  • the first ply can be thicker than the second ply.
  • the first ply is also referred to as mould layer.
  • the mould layer or first ply can be thicker than the second ply.
  • the second ply is also referred to as short-former layer.
  • the short-former layer is advantageously the thinner layer.
  • the invention also provides a method of manufacturing the security element according to the aspects and embodiments of the invention and a method of manufacturing a valuable document, in particular a banknote, comprising the security element.
  • the grooves are formed by method steps relating to watermarking.
  • the first groove can be formed by drainage control, i.e. by a locally reduced dewatering region. By locally different dewatering conditions, a reduced thickness can be achieved in the region of the first groove.
  • This aspect advantageously applies to the first ply, i.e. the mould layer, if the first ply is the thicker layer.
  • the second ply can then sink or settle into a groove on the second surface of the first ply in order to form the second groove.
  • the drainage control can be used to produce two superposed grooves on the first ply.
  • One of the grooves is the first groove, while the other groove serves as a depression in which the second ply (short-former layer) sinks in order to form the second groove on the opposite surface of the substrate.
  • the second ply is removed first in order to create the second groove and then the first groove is created as a result of the missing second ply of the second groove.
  • the second groove is created first, and by natural compensation of the internal tension during the paper formation, the first groove is spontaneously generated on the other side.
  • the first groove and/or the second groove can be formed by lamination or localized calendering such that the fibers of the substrate are more compressed in the area of the first groove and/or the second groove.
  • the bottom of the grooves is more compressed, i.e. the remaining layer or layers of the substrate are more compressed.
  • first groove in the first layer can also be formed by mould cover relief.
  • the first foil and/or the second foil can be configured such that the first groove and/or second groove are unperceivable to the naked eye.
  • the reduced thickness of the substrate in the area of the grooves can become visible as an increased transparency of the substrate.
  • either one or both of the foils can be made substantially opaque.
  • the grooves are then hidden due to a specific property of one or both foils.
  • a pigment may be added to the first and/or second foil in order to make one or both foils opaque.
  • a metallic layer may be applied to one or both foils in order to render the grooves unperceivable.
  • either one or both of the foils may be made of polymers which are inherently opaque.
  • a pigment may be added to the second foil (backside foil) and a metallic or an opaque carrier medium may be added to the first foil (front foil).
  • the invention also provides a valuable document comprising the security element according to the aspects and embodiments of the invention.
  • the valuable document is advantageously a banknote.
  • the first and second groove as well as the first and second foil may then advantageously extend over the full width or length of the valuable document, in particular the banknote.
  • the sandwich structure of the first and second groove, remaining layer of the substrate and first and second foil extends over the width or length of the valuable document.
  • FIG. 1 shows a simplified cross sectional view of a security element 10 according to an embodiment of the invention.
  • the substrate 1 has a first grove 2 on a first surface.
  • On the opposite surface of the substrate 1 is a second groove 3.
  • the first groove 2 and the second groove 3 are superimposed, i.e. they are aligned one above the other.
  • a first foil 4, in form of an elongate strip, is arranged in the first groove 2.
  • a second foil 5, also in the form of an elongate strip, is arranged in the second groove 3.
  • the first foil 4, the second foil 5 and the remaining layer 8 of the substrate 1 between the superimposed grooves 2, 3 form a sandwich structure. Accordingly, a sequence of foil, substrate and foil is provided while the two foils are substantially arranged in respective grooves.
  • the width of the first foil 4 is F1W.
  • the thickness of the first foil 4 is F1T.
  • the width of the second foil 5 is F2W.
  • the thickness of the second foil 5 is F2T. In this embodiment, the thickness F1T of the first foil 4 is greater than the thickness F2T of the second foil 5.
  • the width of the first groove 2 is G1 W.
  • the depth of the first groove is G1T.
  • the width of the second groove 3 is G2W.
  • the depth of the second groove is G2T.
  • the width G1 W of the first groove 2 is slightly greater than the width F1 W of the first foil 4. This means that the width G1W of the first groove 2 is dimensioned such that the first foil 2 fits into the first groove 2.
  • the thickness F1T of the first foil 4 is greater than the depth G1T of the first foil 4. This allows even complex security features to be incorporated into the first foil 4 rather than into the second foil 5 which is thinner than the first foil 4.
  • the thickness F2T of the second foil 5 is greater than the depth G2T of the second groove 3.
  • the thickness F2T of the second foil 5 can even be greater than the sum of the thicknesses G1T, G2T of both grooves 2, 3 (i.e. F2T can be greater than G1T + G2T).
  • the thickness of the second foil 5 can be greater than the depth of the second groove, for example by 5 ⁇ m to 35 ⁇ m.
  • the width G2W of the second groove 3 is lower than the width F2W of the second foil 5. This means that the width G2W of the second groove 3 is dimensioned such that the second foil 5 (slightly) overlaps the longitudinal edges of the second groove 3. This small overlap has turned out to be tolerable and it simplifies the manufacturing procedure.
  • the width of the second foil 5 can, for example be greater than the width of the second groove 3 by 1 mm to 4 mm.
  • the width F2W of the second foil is also greater than the width G1W of the first groove 2.
  • the first and/or second foil 4, 5 advantageously have a width generally ranging between 8 mm and 30 mm, a thickness ranging between 10 ⁇ m and 50 ⁇ m, and a position from one edge to the opposite edge, across an entire length or an entire width of the substrate 1 and therefore do not occupy the entire surface area of the substrate 1.
  • the width G1W of the first groove 2 can range from 0.8 cm to 3 cm.
  • the width G2W of the second groove 3 can also range from 0.8 cm to 3 cm.
  • the width F1W of the first foil 4 can range from 0.8 to 3 cm.
  • the width F2W of the second foil 5 can range from 1 cm to 4 cm. This implies that the width F2W of the second foil 5 can advantageously always be greater than the width G2W of the second groove 3.
  • the width F1W of the first foil 4 can be equal to or lower than the width G1W of the first groove 2.
  • the width F1W of the first foil 4 can, for example be lower than the width G1W of the first groove 2 by 1 mm to 6 mm.
  • the foils 4, 5 compensate the mechanical properties (for example resistance) due the reduced thickness of the substrate in the area of the grooves.
  • the grooves compensate the additional thickness of the foils.
  • the thickness of the foils 4,5 is only partly compensated by the depth of the grooves 2,3.
  • the sandwich structure of the security element 10 provides high quality, stability, durability and processability.
  • the first foil 4 and the second foil 5 are not necessarily entirely embedded into the substrate 1. Certain overlaps due to the thickness F1T of the first foil 4 and the width F2W of the second foil 5 are acceptable. This simplifies production.
  • FIG. 2 shows a simplified perspective view on the security element shown in FIG. 1 .
  • the foils 4, 5 and the grooves 2, 3 extend over the entire substrate.
  • the lengths of the first and second groove G1 L, G2L and the lengths of the first and second foil F1 L, F2L are then equal.
  • FIG. 3 shows a simplified cross sectional view of a substrate 1 according to an embodiment.
  • the reduced thickness of the substrate in the area of the first groove 2 and the second groove 3 is mainly or exclusively achieved by localized drainage variations on the first ply 6 (mould layer).
  • the thinner second ply 7 (short-former layer) mainly sinks into the groove on the surface of the first ply 6 which is opposite to the first groove 2.
  • the thickness of the first ply 6 is SP1T outside the groove areas of grooves 2, 3.
  • the thickness of the second ply 7 is SP2T outside the groove areas of grooves 2, 3.
  • the first ply 6 has only thickness of SP1T* with SP1T being greater than SP1T*.
  • the second ply 7 has the thickness SP2T* with SP2T* being equal to SP2T.
  • the thickness of the remaining layer 8 between the grooves is then SP1T* plus SP2T*.
  • the thickness SP1T*+SP2T* of the remaining layer 8 of the substrate in the area in which the first groove and the second groove are superposed can be 80 ⁇ m to 130 ⁇ m. However, this value also depends on the overall thickness of the substrate. In terms of the reduction of the thickness of the substrate due to the first and second groove, the reduction can range from 4 ⁇ m to 35 ⁇ m, and advantageously from 8 ⁇ m to 12 ⁇ m.
  • the advantage of using localized varying drainage is that the bottom surface of the grooves remains rather flat over the entire surface of the bottom surface.
  • FIG. 4 shows a simplified cross sectional view of a substrate 1 according to another embodiment.
  • the first ply 6 only has a groove on its outer surface which is the first groove 2.
  • the second groove 3 is formed by removing the second ply 7 in the area of the second groove 3.

  • FIG. 6 shows a simplified cross sectional view of a substrate 1 according to still another embodiment.
  • the two groves are formed by mould cover relief modulation. Similar to the embodiment of FIG. 3 , also here two superimposed grooves are only generated on the first ply 6. The thickness of the second ply 7 remains unaffected.
  • This well-known method of creating grooves or depressions in fibrous substrates has the disadvantage that the bottom surface of the grooves is uneven and that the edges of the grooves are less steep and sharp than with the other methods of manufacturing the grooves.
  • the first foil 4 and/or the second foil 5 can be configured such that the first groove 2 and/or second groove 3 are not perceivable to the naked eye.
