Description

  The present invention relates to an anti-counterfeit medium used for securities such as gift certificates and gift certificates that are called “prepaid certificates”.

  Since gift certificates and gift certificates can be exchanged for products, goods, and services of the amount displayed on the ticket surface, they have the same value as banknotes and must be prevented from forgery. Gift certificates such as beer tickets that can be exchanged for gift certificates issued by department stores, credit card companies, etc., or products of the amount displayed on the ticket issued by manufacturers or industry groups, are used and used in large numbers. In order to prevent forgery that has been increasing year by year, watermarks are applied to the base paper in advance, or special printing such as micro letters, intaglio, hidden letters, and fluorescent printing, and metallic gloss foil and hologram foil are used. Generally, it is transferred or sealed. Patent Document 1 discloses a paper having a configuration in which a thread is exposed in a window opening portion of a paper layer in order to prevent forgery. Patent Document 2 discloses, as a more advanced method, forgery with a thread having a volume hologram. Prevention paper is disclosed.

  In addition, in the case of gift certificates and the like, the types of tickets are finely divided for each amount of money, and management at the time of production, inventory management, collection management, and the like are complicated. In addition, when the gift certificate owner uses the product for purchase of a product having a value equal to or less than the face value in a store or the like, there are many cases where no change is made, and the use conditions are limited. In addition, the gift certificates collected after use become a huge amount of garbage, but cannot be disposed of as general securities, so a huge disposal cost is also incurred.

In addition, in recent years, although it is different from gift certificates, etc., it is a point card using a card capable of recording variable information, a commuter pass such as trains, buses, etc., and can be used for purchasing products with a prepaid amount. Magnetic cards or IC cards have become widespread. As disclosed in Patent Document 3, there is an information recording medium having both a forgery prevention function by hologram and a rewrite printing function. For example, it is not necessary to issue a new commuter pass for a commuter pass such as a train if the validity period is renewed, and it is not necessary to issue a new card for a point card by rewriting the number of points, expiration date, etc.

  However, even with the configuration of Patent Documents 1 to 3 described above, the necessary function as a prepaid voucher is retained and the counterfeiting effect is eliminated with the stock of gift certificates, etc. as one ticket type while retaining the forgery prevention effect. However, it is also possible to purchase a product with a value less than the face value, and a recyclable gift certificate cannot be obtained. Copying a foil with a metallic luster such as a thread of a hologram with an electronic copying machine results in a black copy, so it can be seen at a glance that it is a duplicate, but it is pasted with a similar foil with a metallic luster. When attached, there was a problem that it was difficult to distinguish from counterfeits. In addition, there is a great demand for a gift certificate with high anti-counterfeiting property that can be used by an unspecified person and can be used by an unspecified person and the amount of money that can be used and the unused balance can be visually recognized.

  The purpose of the present invention is to maintain the effect of preventing counterfeiting as gift certificates or gift certificates, while eliminating the complexity of production and inventory management associated with the issuance of a large number of ticket types, and balance display is possible when used below the ticket amount. And it is providing the forgery prevention medium which can be recycled.

The present invention relates to a forgery prevention medium in which a thread is formed in a paper base material, wherein the thread is a rewrite film provided with a rewritable rewrite recording display layer, and the thread is the rewrite recording display layer. A forgery prevention medium characterized in that it is partially exposed on the surface so that printing, rewriting, erasing, and display can be recognized.

  Hereinafter, the configuration of the forgery prevention medium of the present invention will be described in detail.

  The anti-counterfeit medium according to the present invention basically has a configuration in which a thread (thread rewrite) 2 of a rewrite film is formed in a paper substrate 1, or a striped rewrite film (stripe rewrite) on the surface of the paper substrate. 3 or a spot-like rewrite film (spot rewrite) 4 is transferred or laminated. This rewrite film includes at least a rewrite recording display layer capable of rewriting information recording. The rewrite recording display layer can be formed by a known method, and is formed on a thread base material having mechanical strength capable of making paper, or is formed as a foil-like film that can be transferred to the paper surface. .

  The rewrite recording display layer is a layer that can rewrite information recording, and white turbid rewrite and leuco rewrite are used as reversible recording materials.

  The white turbid relite is composed of behenic acid, eicosane diacid, succinic acid in thermoplastic resins such as polyvinyl chloride resin, vinyl chloride-vinyl acetate copolymer, vinyl chloride-vinyl acetate-vinyl alcohol copolymer, acrylic resin. In this method, an aliphatic dicarboxylic acid such as adipic acid, succinic acid, pentadecanoic acid or malonic acid is dispersed, and the phenomenon that the recording layer repeats white turbidity and transparency by heating and cooling is utilized.

  Leuco-type lyrite shows acid properties under high temperature heating, and amphoteric colorant and leuco compound, which show base properties under low temperature heating, are combined with polyvinyl chloride resin, vinyl chloride-vinyl acetate copolymer, chloride Dispersed in a thermoplastic resin such as a vinyl-vinyl acetate-vinyl alcohol copolymer and an acrylic resin. Since the amphoteric compound, a subtractive colorant, exhibits the properties of an acid or a base due to the action of heat, it acts as an acid under high-temperature heating, and the released hydrogen ions open the lactone ring of the leuco compound, thereby opening the leuco compound. The compound is developed. On the other hand, it acts as a base under low temperature heating, and utilizes the phenomenon of closing the lactone ring of the leuco compound and reducing the color of the leuco compound. As this color-developing agent, hydroxybenzoic acid, hydroxysalicylic acid, gallic acid and the like can be used. Further, as the leuco compound, crystal violet lactone, 3-diethylamino-7-chlorofluorane, 2- (2-fluorophenylamino) -6-diethylaminofluorane, etc. having a partial skeleton of lactone, sultone, spirofuran, etc. are used. it can.

  Since the anti-counterfeit medium of the present invention is printed by an issuing machine or a processing machine equipped with a thermal head and used repeatedly, the above-described rewrite recording display layer is required to have durability. Therefore, the rewritable recording display layer is usually provided with a protective layer made of a transparent resin that protects the surface from scratches and scratches and has resistance to living substances (such as liquor and water). Examples of the resin used include acrylic resins, urethane resins, vinyl chloride-vinyl acetate copolymer resins, polyester resins, melamine resins, polyimide resins and other thermoplastic resins, thermosetting resins, ultraviolet rays, or electron beams. The curable resin may be used alone or as a mixture, but is not limited to these in the present invention.

  The thread used in the present invention has at least the rewrite recording display layer 15 and the protective layer 16 laminated on the thread base material 11, and usually further above and below this laminate, the binding strength of the thread to the plant fiber and the like when paper is made. The binder layer 17 for imparting is provided. As the binder layer, starch-based, methylcellulose-based, carboxylated cellulose-based, hydroxyethylcellulose-based, polyvinyl alcohol-based, polyvinylpyrrolidone-based, vinylethylether-maleic anhydride copolymer system, polyacrylic acid-based, polyethylene oxide-based, etc. It is provided with a film thickness of about 1 to 10 μm by various coating methods such as gravure coating. Since the binder layer has a strong affinity with plant fibers and a high hydrophilicity, it does not remain on the surface of the protective layer of the rewritable recording display layer partially exposed, and does not hinder printing.

  As the thread base material, it is common to use a polyethylene terephthalate resin film that has a stable thickness, is mechanically strong and has flexibility and flexibility, but is not limited to this. A film made of a polymer material such as acrylate is used as necessary. The thread base material preferably has a thickness of 15 to 50 μm. After laminating the above-described rewrite recording display layer, protective layer, and binder layer on a thread base material by a known coating method or the like, it is slit to a desired width to obtain a thread for paper making.

  The thread can be drawn into the paper base by a known method. For example, as disclosed in Japanese Utility Model No. 3028886, the thread is exposed in the window opening of the paper layer. For example, the thread may be partially exposed from the paper.

  In addition, the rewrite film transferred or laminated in the form of stripes or spots on the surface of the paper base material in the present invention is basically formed by laminating the same material as the above-described rewrite recording display layer and protective layer on the base film. Is. When laminating, the substrate film 12 is provided with a rewrite recording display layer 15 and a transparent resin protective layer 16 and an adhesive layer 18 is provided on the back side thereof, and then slitted to a desired width on the surface of the paper substrate. Lamination is performed by a known method. In the case of transfer, a protective layer 16 is first formed as a release layer on the transfer substrate 13, and a transfer sheet in which a rewrite recording display layer 15 and a transfer adhesive layer 18 are provided in that order is prepared on the surface of the paper substrate. Transfer is performed by a known method. In this case, unlike the thread engraving type, it is also possible to apply a rewrite film to paper that has been previously offset printed.

  When using the above-described anti-counterfeit medium of the present invention as a gift certificate or the like, the issuer prints the amount or quantity on the rewrite recording display layer with an issuing machine equipped with a thermal head. Here, considering the anti-counterfeit effect, it is possible to print the original pattern or mark of the issuer at the same time, and it is also possible to handle it as securities only after passing through the issuer of the issuer. Normally, printing is performed by developing the rewrite recording display layer directly, but the amount or quantity is displayed on the paper by printing in advance, and a cloudy or transparent rewrite film is laminated or transferred to The same display by printing can be achieved by raising or hiding the base by heating the head. For this reason, there is no need to have a stock in which ticket types are finely divided for each amount as in the conventional case, and there is an advantage that the management of the issuer can be concentrated on the amount output at the issuing machine.

  When using the gift certificate etc. in exchange for goods or goods / services below the amount or quantity displayed by the user, as the gift certificate etc., the forgery prevention medium of the present invention issued by the issuer described above, An unused balance or an unused quantity is printed and displayed on a rewrite recording display layer by a processing machine equipped with a thermal head installed in a store or the like. This makes it possible to reuse the remaining value, thereby solving the conventional problem of no change.

  When the anti-counterfeit medium of the present invention is used as a gift certificate or the like and collected after use, the issuer erases the amount or quantity display of the rewrite recording display layer with an issuing machine equipped with a thermal head, and again the rewrite recording display layer The amount or quantity can be printed and reissued, and the amount of garbage that is difficult to dispose of as securities can be reduced.
