Description

  The present invention relates to a printed matter having anti-counterfeit printing using metal foil and pearl printing, and braille, three-dimensional characters and symbols.

In securities such as gift certificates and lotteries, various measures such as printing using special ink are taken in order to suppress and prevent counterfeiting. However, anti-counterfeit printing using special ink often requires special equipment for authenticity determination, and anti-counterfeit printing that can easily determine forgery instantly is desired.
Printing using gold foil, hologram foil, or pearl printing is difficult to copy with a copying machine using electrophotographic technology, and it is easy for ordinary people to determine forgery instantly, so anti-counterfeiting technology (mainly copy protection) ) Is generally used. In addition, since it has a glossy and beautiful appearance and can attract attention, it is highly useful in terms of design.
However, gold foil, hologram foil, and pearl printing are easy to counterfeit once the materials are obtained. Therefore, when used alone, the anti-counterfeiting effect is sufficient to prevent copying by a copying machine using electrophotographic technology. It is gone. Also, when using hologram foil with advanced technology such as 2D type and 3D type, it is difficult for amateurs to easily judge the difference between foils, and further technical design to use the foil alone Changes are required. For this reason, in securities such as gift certificates and lotteries, anti-counterfeit prints in which a metal foil layer such as a gold foil or a hologram foil and a pearl print layer are combined are used.

For securities and lotteries, it is important not only to prevent forgery printing but also to convey information correctly. Now that an aging society has been reached, it is becoming common to display large text information on printed materials. In addition, it is pointed out that it is important not only to transmit information such as text information via vision but also to use information transmission through senses such as palpation. As means for transmitting information through a sense, there is printing in which braille, characters, symbols, figures, or the like are three-dimensionally formed. For example, Patent Document 1 discloses a printed matter in which a projection part of an ultraviolet curable resin having a desired shape is formed on a printing substrate such as paper or a plastic sheet.

  However, since securities, lotteries, and the like have a limited printing space, there is a problem that it becomes difficult to secure an anti-counterfeit printing area combining a metal foil layer and a pearl printing layer when a character is enlarged.

  In addition, securities and lotteries are frequently used in authenticity determination machines and number confirmation machines, so braille, three-dimensionally formed characters, symbols or figures (hereinafter referred to as three-dimensional information transmission means). May be adversely affected such as damage to securities due to the unevenness. In particular, when the three-dimensional information transmission means is formed on the pearl printing layer with an ultraviolet curable resin, there is also a problem that the three-dimensional information transmission means is easily peeled off from the pearl printing layer. The combination of anti-counterfeiting printing combined with three-dimensional information transmission means has been avoided.

  SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a forgery-preventing printed matter that includes three-dimensional information transmission means, is difficult to copy by a copying machine, and can easily determine forgery instantly by ordinary people. Objective.

In order to achieve the above object, the printed matter of the present invention includes a metal foil layer, a pearl print layer provided on the metal foil layer, and a protruding layer provided on the pearl print layer in a desired region of the substrate. It has the structure provided with the laminated body which consists of.
The present invention also provides a metal foil layer, a pearl print layer provided on the metal foil layer, a protective layer provided on the pearl print layer, and a protective layer in a desired region of the substrate. Provided is a printed matter comprising a laminate comprising a protruding layer.

  Since the printed matter of the present invention does not impair the anti-counterfeiting effect by the metal foil or pearl printing, the character information and the three-dimensional information transmission means (that is, a protruding layer such as Braille) without restricting the area of the anti-counterfeit printing. ) Can be combined. In addition, since the separation between the pearl print layer and the three-dimensional information transmission means can be prevented, damage to the printed matter can be suppressed in mechanical processing or the like.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>
FIG. 1 is a cross-sectional view showing a first embodiment of a printed matter according to the present invention. The printed material 1 is configured by sequentially laminating a metal foil layer 11, a pearl printed layer 12, and a protruding layer 13 in a desired region on the substrate 10.

  The base material 10 can be used by selecting appropriate materials such as securities, lotteries, passports, identification cards, etc., for example, fine paper, art paper, coated paper, Japanese paper, various laminated papers, and various other fibers. And leather.

As described above, the metal foil layer 11 is not only a layer made of a foil having a monochromatic specularity and metallic luster such as a gold foil or a silver foil, but also has an interference fringe like a hologram foil. It includes a layer of foil that reproduces the image.
The metal foil layer 11 can be formed by pressing a gold foil, a silver foil, or a hologram foil in a solid shape with a flat pressure plate or a cylinder plate on a desired portion or the whole of the substrate 10.

The pearl print layer 12 is prepared by mixing a pearl pigment in which titanium oxide or iron oxide is coated with mica or metal powder with a solvent-based ink for a pearl print layer composed of a polymer, a colorant, a solvent, and the like. It is formed above. Characters, symbols, graphics, or a combination thereof may be printed. In printing, a diluting solvent may be added in an amount corresponding to the printing conditions in accordance with the printing suitability of the solvent-based ink for the pearl printing layer. As the printing method, a solvent-based ink is applied to the entire surface of the metal foil layer 11 or a predetermined region, in addition to a gravure printing method, a screen printing method, a flexographic printing method, various commonly used printing methods, or a plurality of these printing methods. Can be combined.
The mirror effect of the metal foil layer 11 may be lost depending on the film thickness of the pearl print layer 12. In order to maintain the mirror effect, the film thickness is preferably in the range of 5 to 10 μm.

  As the polymer, a transparent single molecular polymerization resin or copolymer resin such as thermoplastic resin or thermosetting resin can be used. For example, polystyrene resin, polyester resin, acrylic resin, silicone resin, fluorine resin Resins, polyamide resins, polyvinyl alcohol resins, polyurethane resins, polyolefin resins, polycarbonate resins, polysulfone resins, polyester resins, and vinyl chloride-vinyl acetate copolymer resins are used as components. These resins may be used alone or in combination. Moreover, although organic solvents, such as toluene, xylene, cyclohexanone, methyl ethyl ketone, ethyl acetate, can be used for a solvent, it is not limited to these. A colorant can be mix | blended to such an extent that the transparency of the pearl printing layer 12 is not inhibited, A kind is not specifically limited, A general pigment and dye can be selected and used. The dilution solvent to be blended with the solvent-based ink for the pearl printing layer may be appropriately selected from commonly used xylene, methyl isobutyl ketone, cyclohexanone, and the like.

The protruding layer 13 is formed on the pearl print layer 12 by Braille, characters, symbols, figures, or a combination thereof. The protruding layer 13 is formed into a protruding shape with a transparent resin. Braille, letters, symbols, figures or combinations thereof on the protruding layer 13 may be along or different from those formed on the pearl print layer 12.
The transparent resin preferably contains the same polymer as that of the pearl print layer 12, and the resin containing the above-described polymer may be used. Note that a resin that is quickly solidified is desirable, and an ultraviolet curable resin or an electrocurable resin that can control the solidification may be used.
In order to form the transparent resin in a protruding shape, gravure printing, screen printing or flexographic printing can be used, but screen printing and gravure printing are preferred.
The thickness of the protruding layer is not particularly limited, but when it is set to braille using an ultraviolet curable resin, it is defined as 300 μm to 500 μm according to JIS T9253, and in this case, it is formed by screen printing. Need.

  The printed matter 1 has a metal-colored metal foil layer 11, a pearl print layer 12 that changes color depending on the viewing angle, and a transparent protrusion layer 13. When this is copied by a color copying machine, the metal foil layer 11 is black. Since the copy of the monochromatic pearl print layer 12 and the protruding layer 13 that do not change color is emphasized, it is difficult to reproduce or forge with a copying machine.

<Second Embodiment>
FIG. 2 is a cross-sectional view showing a second embodiment of a printed matter according to the present invention. In this example, the printed material 2 is configured by laminating a pearl print layer 12, a protective layer 14, and a protruding layer 13 in this order on a metal foil layer 11 formed in a desired region on the substrate 10. .
Since the pearl print layer 12 includes a scaly pearl pigment coated with a metal powder, the pearl pigment may be exposed. In this case, if the protruding layer 13 is formed directly on the surface of the pearl printed layer 12, the adhesive force between the pearl printed layer 12 and the protruding layer 13 may be weakened.

The protective layer 14 is a resin layer provided on the pearl print layer 12 in order to enhance the adhesion between the pearl print layer 12 and the protruding layer 13. The resin constituting the protective layer 14 is preferably a transparent resin containing as a component the same polymer as that of the protruding layer. In particular, the protrusion layer is preferably an ultraviolet curable resin, and in this case, the protective layer 14 is also an ultraviolet curable resin.
By making the component of the high molecular polymer forming the protective layer 14 the same as that of the protruding layer 13, the effect of making it difficult to separate the pearl printed layer 12 and the protruding layer 13 is enhanced.
The thickness of the protective layer 14 is not particularly limited, but is preferably 50 μm to 100 μm. For the formation of the layer, not only a gravure printing method, a screen printing method and a flexographic printing method but also various general printing methods can be used, and screen printing (silk wrinkle of about 200 L / inch) is preferable.

  In order to further enhance the prevention of peeling of the protruding layer 13, a film covering the protruding layer 13 may be formed. The coating may be formed so as to cover a part or the whole of the pearl print layer 12 and the protruding layer 13, or may be formed so as to cover a part or the whole of the metal foil layer 11. When a film is formed so as to cover the protruding layer 13 from a part or the whole of the pearl print layer 12, it is necessary to include the same or part of the same component as the resin component constituting the pearl print layer. When a film is formed so as to cover the protruding layer 13 from a part or the whole of the metal foil layer 11, it is necessary to include the same or partly the same component as the resin component constituting the protruding layer.

<Third Embodiment>
FIG. 3 is a cross-sectional view showing a third embodiment of the printed matter according to the present invention. In this example, the protective layer 14 of the printed material 3 covers the pearl printed layer 12 and is bonded to the metal foil layer 11 at the edge 20. By forming the protective layer 14 in this way, it becomes possible to reinforce the adhesiveness of the metal foil layer 11, the pearl print layer 12, and the protrusion layer 13 as compared with the second embodiment. Further, a layer of a polymer having the same component as the protrusion layer 13 may be formed on the protrusion layer 13 to cover the protrusion layer.

  As described above, it is also a desirable mode to further enhance the prevention of peeling of the protruding layer 13 by forming a film covering the protruding layer 13. The coating may be formed so as to cover a part or the whole of the pearl print layer 12 and the protruding layer 13, or may be formed so as to cover a part or the whole of the metal foil layer 11. When a film is formed so as to cover the protruding layer 13 from a part or the whole of the pearl print layer 12, it is necessary to include the same or part of the same component as the resin component constituting the pearl print layer. When a film is formed so as to cover the protruding layer 13 from a part or the whole of the metal foil layer 11, it is necessary to include the same or partly the same component as the resin component constituting the protruding layer.

  A pearl printing layer in which 18 parts (by weight) of a pearl pigment (Iriodin IR201 / Merck Japan) is added to 100 parts (by weight) of solvent-based ink having the following composition on a printed material (made by Murata gold foil) with gold foil stamped on cardboard. A pearl print layer was formed by screen printing (silk wrinkle 305 L / inch) using a solvent-based ink and 50 parts (by weight) of a diluting solvent.
