Definitions
- the invention relates to the field of security documents. It relates to a security sheet comprising a security tape and the method of manufacturing the security sheet. It also concerns the security tape itself.
- Security documents are produced from particularly fibrous materials and may include banknotes, identity cards, passports, driving licenses, visas, checks, vouchers, tickets or admission tickets to a cultural or sports event.
- the introduction in strip of said security elements can in particular be done by supply ducts placed along the width and opening into the shape tank nearby. from round form, before the beginning of draining of a fibrous suspension on a fabric of a round form. After draining, a security sheet is obtained which is then pressed and then dried according to the current papermaking process.
- the main drawback relating to said first method of obtaining a band containing security elements is the irregular dispersion of said security elements. Due to the introduction of the elements, it is difficult to obtain a band whose edges are regular and within which the distribution of the elements of security is relatively homogeneous, in the width (x) and in the length (y) but also in the thickness (z) of said security sheet.
- bandwidth and spatial distribution (x, y, z) of the security elements can be particularly troublesome in the case of recognition and / or authentication and / or identification based on the spatial distribution (x, y , z) said security elements in said security document. Indeed, because of too great variability, the use of the position or the width of said band, or the spatial distribution of said security elements, for purposes of recognition and / or authentication and / or or identification, may in particular be impossible to implement.
- recognition applies when a document or element of a document is compared to a reference to determine the authenticity of that document document or element
- authentication means determining whether the document is authentic or whether it has been falsified or counterfeited
- identity is the verification of the identity of the owner of a given document.
- the type of problem mentioned above is encountered in the case of authentication of security elements automatically using a non-portable device based on the specific signal of one or more elements (s). ) of security.
- some of said security elements are covered with a layer of fibers and / or mineral charges too thick to allow the correct detection of their specific signals by said automatic authentication device.
- said introduced security threads generally have a width of less than 10 mm, a thickness of between 12 and 45 ⁇ m and are, in most cases, made up of ribbons of plastic materials, in particular based on polyester.
- Said security son are in particular secured by visible or non-visible patterns, in positive and / or negative, optically variable devices and in particular holograms, luminescence and in particular fluorescence, magnetism, electrical conduction or still thermochromic.
- Said security threads are incorporated inside the fibrous substrate constituting said security sheet is "en masse", that is to say completely covered with fibrous material, or “window”, said security thread being then located on the surface of said security sheet and en masse in the latter, for example in an alternating manner.
- the windows thus described may or may not be through, depending on whether said security thread appears respectively on two or on one side of said security sheet.
- the introduction of said security son en masse can in particular be carried out in a single jet, on a paper machine flat or round table.
- the wire is introduced into the shaped tank before or shortly after the beginning of the draining of the fibrous suspension on the fabric.
- the position of said security thread in the thickness of the final security sheet is determined in particular by the place and the insertion inclination of said security thread.
- the jet thus obtained can then be married in the wet state, that is to say before drying, with other jets whose fibrous compositions can be identical or different and which can be formed on paper machines at the table flat or round.
- Another way of introducing said security son en masse is to incorporate them between two successive jets produced on a flat table and / or a round shape, before the "marriage" of said successive jets by wet pressing.
- Said jets can themselves be married to other jets whose compositions may be identical or different and which can be formed on a flat table or a round shape, before or after the introduction of said security son. After their marriage, the two successive streams comprising said security son are eventually married to the other jets and then dried according to the current papermaking process to obtain a security sheet.
- said security threads may in particular be coated with an adhesive, for example heat-sealing products also called hot-reactive products.
- the introduction of said security threads may in particular lead to a poor overlap of said security threads characterized, when they are introduced en masse, by a lack of material above said security threads and, when they are introduced in a window, by insufficient bridging.
- bridging is meant the fibrous covering of a security thread introduced in the windows in the zones between the windows, that is to say at the places where the thread is contained in the mass of said security sheet.
- the adhesives for example heat-sealing coatings, which can be added to said security threads develop their adhesive properties only after drying of said paper sheet containing said security threads, and the plastic materials constituting said security threads being hydrophobic
- said security son of the art prior art do not develop any bond with the fibrous substrate of said security sheet during dewatering and pressing which take place in wet part, that is to say, before drying of the sheet. Consequently, the introduction of said security threads weakens said security sheet along the introduction strip, the adhesion properties of said security thread coated with an adhesive, for example a heat-sealing product, not being developed only during drying.
- said security threads are too wide, their impermeability impedes the drainage of the water contained in the fibers located above the son and thus prevents the consolidation of the fibrous mat, which causes in particular breakage of the sheet partially wet paper during the production of security sheets containing said security threads.
- the width of said security son exceeds about 1.5 cm, the fibrous mat is no longer strong enough and causes too many breaks of the paper sheet to allow a correct machinability of the paper machine.
- the materials of which said security threads are composed are generally plastic films which are optionally metallized and then possibly coated with varnish.
- Another disadvantage of said security threads is that they can be combined only with very fine particles and, in particular, by printing and / or metallization.
- the incorporation of flat security elements and relatively small size, such as boards, is impossible because of the materials of which said security son are constituted.
- the European patent application EP 0 557 157 of the Applicant describes the manufacture of a security sheet having monochrome or polychrome signs visible in transmitted light.
- the security sheet is manufactured from at least two fibrous jets and a strip having monochrome or polychrome marks introduced between the two fibrous jets.
- the strip thus introduced advantageously comprises cellulose fibers and a soluble and / or fusible binder product so that said product can be dispersed during the incorporation of the strip between the two jets so that the band disappears within sheet and that the printed marks are intimately linked to the sheet.
- the band thus obtained is completely destructured within the security sheet.
- Requirement FR 2 847 915 discloses the incorporation, into a secure paper, of a ribbon made of a different tissue from a paper.
- the French patent application FR 2 679 934 of the Applicant describes a system for authenticating a security paper using a first chemical reagent present on the security paper, an authentication composition comprising a second chemical reagent forming a colored product with the first chemical reagent and an erasing composition of the colored product.
- the chemical reaction occurring during the authentication between the second reagent and the first chemical reagent only produces a coloration of the zone where the reaction occurs.
- WO 2006/095033 relates to a safety band comprising a ribbon of a cellulosic support formed of vegetable fibers.
- the cohesion and the integration of the ribbon in the substrate of the strip are ensured by the creation of chemical bonds between the vegetable fibers contained in the ribbon and in the substrate, in particular hydrogen bonds, but do not allow the ribbon to maintain its integrity. and its cohesion within the substrate of the strip, especially when the strip is placed in a wet environment, in case of an attempt to recover the strip by a counter factor, for example.

- the invention can make it possible to provide a security sheet with security elements arranged in a band with a relatively homogeneous spatial distribution (x, y, z).
- the above adhesive optimizes the adhesion of the security tape in the security sheet
