Definitions
- the invention relates to a security sheet comprising information to be disclosed and a substrate with a peelable tape for revealing the information as well as the method of manufacturing said security sheets and the documents comprising said sheet.
- the invention also relates to a method for revealing information.
- Security documents are produced from particularly fibrous materials and may include banknotes, identity cards, passports, driving licenses, visas, checks, vouchers, tickets or entrance tickets to a cultural or sports event, game tickets, especially for games of chance such as scratch, lottery and draw games.
- gaming tickets use a scratch solution to discover an amount to win or other information in connection with the amount to win or if the ticket is a winner or loser.
- Part of the surface of the ticket includes a layer of scratch-resistant opaque ink that masks this information, so when we scratch this layer we discover the information.
- a barcode system is used to validate the winning ticket.
- GB 2 331 270 discloses an information medium comprising a transparent upper layer having a pre-cut area provided with prints, and a non-transparent bottom layer provided with jamming means visible through the upper layer and which prevent visualization of the images. impressions of the upper layer. The observation of the impressions is done by detachment of the precut area. The choice of a top layer that is transparent and specific scrambling means to prevent the reading of the information is binding. Moreover, such an information medium does not offer sufficient security against any attempt to falsification, the precut area can be replaced on the upper layer after being detached.
- a first object of the invention is to solve the disadvantages of the prior art and to propose a new means of disclosure of information in the context of a game ticket or a communication or promotional medium or in any other application.
- a second aim is to also propose a means of masking such information.
- the invention proposes for this purpose to provide a security sheet comprising information to be disclosed and a support formed of a substrate, preferably fibrous, in which is incorporated, preferably totally, a ribbon, preferably fibrous, having a face A and a face B, said tape being peelable along said face B, and said information being carried by and / or facing said face B.
- the ribbon When the ribbon is detached from the sheet by virtue of its peelability at its side B where it separates from the substrate, it is possible to read the information on the side B of the ribbon and / or on another part situated opposite the ribbon. B side of the ribbon, document or article comprising said sheet. In the case of a lottery ticket, for example, the information may indicate the amount of the winnings earned.
- the fact that the ribbon is integrated into the substrate increases the safety of the sheet because any attempt to remove the ribbon abnormally will cause visible damage to said substrate. Also, because of the visible alteration of the substrate, particularly at its parts in contact with the edges or the faces of the ribbon, during an attempt to remove the ribbon, it will be impossible for a falsifier to return to the the ribbon within the substrate.
- the invention thus provides additional security and an easy means of detecting an attempt to falsify the security sheet.
- the ribbon may be partially or completely embedded in the substrate. Also, the ribbon is distinct from the substrate. In particular, the ribbon does not constitute a part of the substrate.

- the security sheet according to the invention is characterized in that said ribbon comprises, on its side B, a low adhesion adhesive agent and on its side A, an adhesive that provides a strong enough cohesion between the ribbon and the substrate.
- the term "adhesive agent of low adhesiveness” means an adhesive agent which provides a weak cohesion, denoted "Cb” between the side B of the ribbon and the substrate while the term refers to "Adhesive” a compound that gives a strong enough cohesion, denoted "Ca", between the side A of the ribbon and the substrate.
- the adhesive used on the side A of the ribbon gives a stronger cohesion between the ribbon and substrate than the low adhesion adhesive agent present on the side B of the ribbon. As explained above, this allows good resistance of the ribbon in the substrate and good peelability.
- the low adhesion adhesive agent present on the side B of the ribbon is characterized in that it provides a level of cohesion Cb between said side B of the ribbon and the substrate less than or equal to 50% at the cohesion level. Ca between the side A of the ribbon and the substrate.
- said security sheet according to the invention is characterized in that said sheet comprises a peel primer made by a half-cut line in the thickness of the sheet, transverse to ribbon, at a depth equal to at least the thickness of the portion of the substrate covering the side A of the ribbon plus the thickness of said ribbon.

- the substrate 4 - ribbon 3 forming the support 2 is driped, pressed and dried.
- a notch is then made in the sheet, at the level of the ribbon 3, by cutting with a knife ("kiss-cutting") so as to cut in the thickness the material above the ribbon 3, adjacent to the side A of the ribbon 3, and said ribbon 3 in its thickness (without cutting the material below the ribbon 3, adjacent to the face B) to form a peel primer 7, this notch being transverse and the width of that of the ribbon 3. affix an adhesive piece called "sticker" at the level of the peel primer 7 on the sheet to make a peel tab 8.
- Said information 5 is masked by the ribbon 3 and the opaque substrate 4.
- a security sheet is manufactured as described above but during the manufacture of the tape is applied to one side of the sheet used to make the ribbons (namely the B side) an adhesive agent of low adhesiveness based on polyurethane in the form of an aqueous dispersion sold under the name Collano DH9044 by the company Collano by a rotogravure process, and by the same method is applied on the other side of the tape (namely the side A) the aqueous heat-sealing adhesive based on polyvinyl acetate marketed under the name Mowilith DC by CELANESE.
- the internal cohesion in SCOTT BOND units is 400 whereas at the level of the ribbon, at the interface between the weakly adhesive side of the ribbon (face B) and the substrate, the internal cohesion is 90.
- a possible embodiment of a sheet according to the invention is described below with reference to FIG. 11.
- opaque ribbons 3 are produced as described in the previous embodiment, the information to be revealed being printed.
- the support 2 substrate4-ribbon3 is made according to a papermaking process on a machine with two round shapes to form two fibrous jets 4a and 4b between which is introduced the ribbon 3, the whole being assembled to the wet state.
- the two jets are different, the jet 4b which will be opposite the B side of the ribbon 3 is opaque black (by adding black dye to the cellulose fibers) and the other jet 4a, facing the side A of the ribbon 3 , has the natural color of a paper.
- a support 2 having a two-colored substrate 4 is thus obtained, the black jet 4b masking the information 5 to be revealed on one side, the opaque ribbon 3 masking it on the other side.
