  Hereinafter, an embodiment of the anti-counterfeit sealed label 10 with an anti-replacement function according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a cross section of an anti-counterfeit sealing label 10 with an anti-replacement function. A security functional layer 1 and an adhesive layer 3 containing a magnetic material are laminated on a base material 2 and contain this magnetic material. The magnetic output of the adhesive layer 3 can be read from above the substrate 2.

  The base material 2 can use paper, an unstretched film produced by extrusion or casting, a stretched film produced by stretching, and the like. The stretched film includes a uniaxially stretched film and a biaxially stretched film depending on how to stretch, and both can be used.

  These unstretched films and stretched film materials include cellophane, polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyolefin (PO), ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVA), polychlorinated. Examples thereof include vinyl, polyethylene naphthalate (PEN), polyethylene terephthalate (PET), nylon, acrylic resin, and triacetyl cellulose (TAC) film.

In particular, the base material 2 preferably has brittleness (fragility). Examples of the material include synthetic resin films such as brittle vinyl chloride and brittle polyester that are made brittle by mixing an appropriate amount of a plasticizer such as kaolin and calcium carbonate, or cellulose acetate, low-density polyethylene, polystyrene, polyphenylene sulfide, and the like. The film etc. which formed the highly crystalline plastic material of this by solution film-forming are mention | raise | lifted. Other materials include UV-cured synthetic resin or UV-cured synthetic resin mixed with an appropriate amount of powder such as kaolin and calcium carbonate, and a film obtained by curing and drying the resin thin film by UV irradiation. . Further, non-woven fabrics made of synthetic fibers or paper such as art paper, coated paper, and high-quality paper can be used.

  Magnetic materials to be included in the adhesive layer include Fe, Ni, Mn, Zn, Co, Permalloy, Sendust, Mn-Zn ferrite, Mn ferrite, Zn ferrite, FeS, magnetite, γ-iron oxide, and Co-coated γ-oxidation. Examples thereof include metals and alloys such as iron, barium ferrite, strontium ferrite and chromium dioxide, and powders of metal compounds. The magnetic material is preferably a soft magnetic material having a holding force of 60 Oe or less.

  As a material for the adhesive layer, if it does not affect the substrate 2, it can be formed using a general adhesive material. For example, vinyl chloride-vinyl acetate copolymer, polyester polyamide, acrylic, butyl rubber, natural rubber, silicone, polyisobutyl adhesive layer alone or alkyl methacrylate, vinyl ester, acrylonitrile, styrene, vinyl monomer Necessary additives such as coagulation components such as unsaturated carboxylic acids, hydroxy group-containing monomers, acryl nitriles, and other reforming components, polymerization initiators, plasticizers, curing agents, curing accelerators, and antioxidants What was added according to it can be used. In particular, it is preferable that it is weak against a solvent or heat.

  These magnetic materials are mixed with the adhesive layer material to make an ink. The pressure-sensitive adhesive layer 3 can be formed by a known gravure printing method, offset printing method, screen printing method, or other printing method, bar coating method, gravure method, roll coating method, or the like.

  The anti-counterfeiting effect can be obtained by coating the adhesive layer 3 containing the magnetic material on the back surface of the base material 2 without the security function layer. That is, after the substrate 2 is peeled off from the adherend with a solvent or heat, only the adhesive layer 3 is removed neatly, and when a counterfeit action is performed such that a new adhesive layer is provided and attached, Since it is impossible to put the magnetic material into the adhesive layer 3, it can be clearly seen that the adhesive layer 3 has been reused by verifying the adhesive layer 3.

  FIG. 2 shows the magnetic material-containing adhesive layer 3 applied in a pattern. Even if it is found that the magnetic material-containing adhesive layer 3 has been subjected to anti-counterfeiting treatment, by patterning, when peeled off from the adherend with a solvent or heat, the pattern will collapse, Again, it is difficult to reproduce the magnetic output pattern, which is very useful for authenticity determination.

  For the security function layer 1 in the present invention, it is preferable to use a material that can be checked for authenticity by visual observation or by using a simple device. Examples of such a material include an OVD functional material, a fluorescent material or a phosphorescent material, or a liquid crystal material.

  An OVD (Optical Variable Device) is an image that uses interference of light, and is a display that produces a color shift in which the color changes depending on the representation of a stereoscopic image and the viewing angle, and is a medium that can be determined by visual inspection. It is. Among them, examples of the OVD such as a hologram and a diffraction grating include a relief type that records light interference fringes on a plane as a fine uneven pattern, and a volume type that records interference fringes in a volume direction.

Also, although the method is different from that of holograms and diffraction gratings, there are multilayer film systems in which thin films of ceramics and metal materials with different optical characteristics are laminated, or materials that cause color change (color shift) depending on the viewing angle due to liquid crystal materials etc. This is an example. These OVDs can be said to be effective means for preventing forgery because they give a unique impression such as stereoscopic images and color shifts and require advanced manufacturing techniques.

  Among these OVDs, in consideration of mass productivity and cost, a relief hologram (or a relief diffraction grating) or a multilayer thin film type is preferable, and these OVDs are generally widely used.

  First, a relief hologram will be described. This relief type hologram or relief type diffraction grating is mass-produced using a relief type press plate having a fine uneven pattern forming a hologram or a diffraction grating, respectively. That is, this press plate heats and pressurizes the OVD forming layer to replicate a fine uneven pattern.

The OVD forming layer is for increasing the diffraction efficiency, and is made of a material having a refractive index different from that of the polymer material constituting the relief surface. As a material to be used, high refractive index materials such as TiO ₂ , Si ₂ O ₃ , SiO, Fe ₂ O ₃ , and ZnS having different refractive indexes, Al, Sn, Cr, Ni, Cu, and Au having a higher reflection effect are used. These materials are used alone or in combination. These materials are formed by a well-known thin film forming technique such as a vacuum deposition method or sputtering, and the film thickness is about 0.5 to 100 nm although it varies depending on the application. In order to prevent the hologram from affecting the communication of the non-contact IC medium, it is desirable to specify a metal vapor deposition portion or use a transparent hologram made of a non-metal vapor deposition material.

Furthermore, a multilayer thin film method will be described. When the multilayer thin film method is used, as described above, the OVD forming layer is formed of a multilayer thin film layer having different optical aptitudes, and is formed by laminating as a metal thin film, a ceramic thin film, or a composite thin film including them together. For example, when thin films having different refractive indexes are stacked, a high refractive index thin film and a low refractive index thin film may be combined, or a specific combination may be stacked alternately. By combining them, a desired multilayer thin film can be obtained.
This multilayer thin film layer is made of a material such as ceramics or metal, and is formed by laminating approximately two or more high refractive index materials and a low refractive index material having a refractive index of about 1.5 with a predetermined film thickness. Examples of materials used are given below. First, as ceramics, Sb ₂ O ₃ (3.0 = refractive index n: hereinafter the same), Fe ₂ O ₃ (2.7), TiO ₂ (2.6), CdS (2.6), CeO ₂ (2.3), ZnS (2.3), PbCl ₂ (2.3), CdO (2.2), Sb ₂ O ₃ (2.0), WO ₃ (2.0), SiO (2. 0), Si ₂ O ₃ (2.5), In ₂ O ₃ (2.0), PbO (2.6), Ta ₂ O ₃ (2.4), ZnO (2.1), ZrO ₂ ( _{2.0), MgO (1.6),} SiO 2 (1.5), MgF 2 (1.4), CeF 3 (1.6), CaF 2 (1.3~1.4), AlF 3 (1.6), Al ₂ O ₃ (1.6), GaO (1.7), and the like.

  And as a metal simple substance or an alloy thin film, Al, Fe, Mg, Zn, Au, Ag, Cr, Ni, Cu, Si etc. are mentioned, for example. Examples of the low refractive index organic polymer include polyethylene (1.51), polypropylene (1.49), polytetrafluoroethylene (1.35), polymethyl methacrylate (1.49), polystyrene (1 .60) and the like.

  By selecting at least one kind from these high refractive index materials or 30% to 60% transparent metal thin film, selecting at least one kind from low refractive index materials, and alternately laminating them at a predetermined thickness, It shows absorption or reflection for visible light.

Each of the above materials is appropriately selected based on optical properties such as refractive index, reflectance, and transmittance, weather resistance, interlayer adhesion, and the like, and is laminated as a thin film to form a multilayer thin film layer. A known method can be used as the formation method, and the film thickness, film formation speed, number of layers, or optical film thickness (= n · d, n: refractive index, d: film thickness) can be controlled. The vacuum evaporation method and the sputtering method are used.
Furthermore, examples of the material that causes color shift include cholesteric liquid crystal. A cholesteric liquid crystal is a liquid crystal aligned in a spiral shape and has a polarization separation ability to reflect right or left circularly polarized light having a specific wavelength. The reflected wavelength is determined by the pitch of the spiral period, and the left and right of the circularly polarized light are determined by the direction of the spiral. In normal observation light, the right and left polarized lights are mixed and the image cannot be confirmed, but only one of the polarized lights can be taken out by holding the polarizing filter and can be recognized as an image.

  In other words, it is called a latent image technique, and the cholesteric liquid crystal is used as a color shift ink and can be camouflaged because the reflection wavelength of reflected light changes depending on the angle. The material causing the color shift is not limited to the cholesteric liquid crystal, and any material that exhibits the same effect may be used. In addition, as a security function, fluorescent ink or phosphorescent ink that can be determined using a verifier or the like may be used.

As fluorescent materials or phosphorescent materials, phosphors include ultraviolet light emitting phosphors and infrared light emitting phosphors, examples of which are given below. The ultraviolet phosphor emits light in the visible wavelength region when irradiated with ultraviolet rays. For example, Ca ₂ B ₅ O ₃ Cl: Eu ²⁺ , CaWO ₄ , ZnO: Zn ₂ SiO ₄ : Mn, Y ₂ O ₂ S: Eu, ZnS: Ag, YVO ₄ : Eu, Y ₃ 0 ₃ : Eu, Gd ₂ O ₂ S: Tb, La ₂ O ₂ S: Tb, Y ₃ Al ₅ O ₁₂ : Ce and the like. The amount of these phosphors added is such that light emission when irradiated with black light can be visually confirmed, or fluorescence can be detected by the light receiving element of the detector.

In addition, infrared emitting phosphors include those that emit light in the visible wavelength region and those that emit light in the infrared wavelength region when irradiated with infrared rays. Examples of the former include YF ₃ : YB, Er, ZnS: CuCo, and the like. As the latter, for example, LiNd _0.9 Yb _0.1 P ₄ O ₁₂ , LiBi _0.2 Nd _0.7 Yb _0.1 P ₄ O ₁₂ , Nd _{0 · 9} Yb _0.1 Nd ₅ (MoO ₄ ) ₄ , NaNb _0.3 Yb _0.1 P ₄ O ₁₂ , Nd _0.8 Yb _0.2 Na ₅ (W0 ₄ ) ₄ , Nd _0.8 Yb _0.2 Na ₅ (Mo _0.5 WO _0.5 ) ₄ , Ce _0.05 Gd _0.05 Nd _0.75 Yb _0.25 Na ₅ (W _0.7 Mo _{0.304 4} ) ₄ , Nd _0.3 Yb _0.1 Al ₃ (BO ₃ ) ₄ , Nd _{0 · 9} Yb _0.1 Al _2.7 Cr _0.3 (BO ₃ ) ₄ , Nd _0.4 P ₅ O ₄ , Nd _0.8 Yb _0.2 K ₃ (PO ₄ ) _{2 and the} like. The latter emits infrared light having an emission spectrum peak at 980 nm to 1020 nm by irradiating light having an infrared wavelength of around 800 nm.

  The amount of the infrared light emitting phosphor added in the ink is such that the light emission can be visually confirmed or the light receiving element of the detector can detect the fluorescence. Furthermore, a latent image capable of performing filter determination may be provided as a security function. As the latent image, a method of providing a known latent image such as a line latent image or a polarized latent image may be used. Further, a heat detection layer or a solvent coloring layer may be provided in order to prevent peeling with heat or a solvent.

  3 and 4 are sectional conceptual diagrams of the anti-counterfeit seal label with the anti-replacement function including the heat detection layer 6, the solvent coloring layer 7, and the non-contact IC medium composed of the IC chip 8 and the antenna 9. FIG. The heat detection layer 6 laminated on the base material 2 is made of a material that changes its hue by receiving predetermined heat or chemically reacts by the action of heat.

As the color developed using the chemical reaction, a reaction between an electron-donating usually colorless or light-colored dye precursor and an electron-accepting compound that reacts when heated to color the dye precursor is used. There is a method in which both coloring components are brought into contact with heat to cause color development. For example, an irreversible thermosensitive color ink composed mainly of a leuco dye that develops color by applying heat and a developer such as bisphenol can be used. The color develops when the leuco dye dispersed in the ink and the developer are combined by heat stimulation. The leuco dye is usually a colorless or light-colored material, and it is suitable to manifest as a color tone when reacted with heat.

  The thermosensitive coloring material used for the heat detection layer 6 is usually a colorless or slightly light leuco dye such as triphenylmethane, fluoran, spiropyran, auramine, phenothiazine, etc., which is a conventional thermosensitive recording. Known leuco dyes from which the material is manufactured can be used. Among them, 3,3-bis (P-dimethylaminophenyl) -phthalide, 3,3-bis- (p-dimethylaminophenyl) -6-dimethylaminophthalide (also known as crystal violet) is typical. Lactone), 3,3-bis (P-dimethylaminophenyl) -6-dimethylaminophenyl, 3-cyclohexylamino-6-chlorofluorane, 3- (N, N-diethylamino) -5-methyl-7- (N, N-dibenzylamino) fluorane, 2- (2-chloroanilino) -6-dinitylaminofluorane, 2- (2-chloroanilino) -6-n-butylaminofluorane, benzoylleucomedilem -1N-phenylrhodamine-β-lactam, amidorhodamine-β-sultone, benzo-β-naphthospiropyran, 6'-chloro -87- Medline Kishi benzoin drill Roh benzo spiropyran, 6'-bromo-8'-methoxy - can be exemplified benzoin drill Roh benzo spiro erosion, etc., but is not limited thereto.

  Examples of the color developing substance that binds to the leuco dye and develops color include 4,4′-isopropylidenediphenol (bisphenol A), 4,4′-inopropylidenebis (2-10 lofenol), 4,4 '-Impropylidenebis (2-methylphenol), 4,4'-isopropylidenebis (2-tert-butylphenol), 4,4'-cyclohexinotritendiphenol, 4-tert-butylphenol, 4 Phenolic compounds such as tert-octylphenol, 4-tert-octylcatechol, α-naphthol, β-naphthol, 4-hydroxy-acetophenol, novolac-type phenol resins, halogenated novolac-type phenol resins and other phenol polymers, benzoic acid Acid, salicylic acid, tartaric acid, etc. It is not limited to this like the ico dye.

Further, as a coloring method other than the above, a method of coloring by containing a substance that changes state such as dissolution / dispersion at a predetermined temperature, or a material in which a dye is put in a capsule that dissolves at a predetermined temperature is used. Examples include a method of coloring.

  The heat detection layer 6 is a printing ink of any one of the above special inks selected from silk printing ink, offset printing ink, gravure printing ink, flexographic printing UV curing ink, oxidation polymerization ink, and heat drying ink. It can also be provided on the entire surface of the label substrate as part of the tint block printing by various printing methods (screen, offset, gravure, letterpress, etc.). As a result, when the label is peeled off by the heat of a dryer or the like, the heat detection layer 6 is colored to leave a trace.

The solvent coloring layer 7 has a property of chemically reacting with a peeling solvent for peeling the substrate 2 attached to the adherend. Examples of the stripping solvent include weakly soluble organic solvents such as ethyl alcohol and acetone, and commercially available seal strippers. The solvent coloring layer 7 has a structure in which dye particles that are insoluble in water and soluble in the peeling solvent are held in a dispersed state with an extender pigment in a resin binder. Thereby, when peeling of the anti-counterfeit sealed label 10 with the anti-replacement function using the peeling solvent is attempted, the pigment held in a dispersed state is dissolved in the solvent coloring layer, and a trace remains as a color on the label substrate. That is, the solvent coloring layer 7 has a solvent coloring function. In addition, as said dye particle | grains, dyes, such as a leuco dye and a fluorescent whitening agent, can be used, for example.

  Furthermore, as a high security function, a non-contact IC medium for performing wireless communication may be provided. The non-contact IC medium is a passive type that does not have an IC chip drive battery. Instead of the passive type, an active type having an IC chip drive battery can be used. In this case, the structure of the non-contact IC medium is complicated, but there is an effect that the reading distance is extended.

  The non-contact IC medium includes an antenna 9 made of a metal such as aluminum or copper, and an IC chip 8 electrically connected to the antenna 9. For example, when the radio wave to be transmitted / received has a frequency equal to or higher than the microwave, the antenna 9 transmits / receives a radio wave when the wavelength of the use frequency is λ and the length in the longitudinal direction of the antenna 9 is set near λ / 2 It can be formed as an efficient dipole antenna 9. Further, for example, when the use frequency of radio waves is 2.45 GHz, the optimum length of the dipole antenna 9 in the longitudinal direction is about 40 mm to 60 mm. The non-contact IC medium receives a radio wave from an information reading device (not shown) by an antenna 9 and supplies a potential difference generated in the longitudinal direction of the antenna 9 to the IC chip 8.

  The IC chip 8 is formed in a square shape, and its side portion has a length dimension of 0.5 mm and a height dimension of 0.1 mm. Note that the length of the side portion can be changed as appropriate instead of 0.5 mm. Further, the shape of the IC chip 8 can be changed as appropriate, for example, a rectangular shape. Also in this case, it is preferable that the length dimension of the side portion (long side portion) is in the range of 0.05 mm to 0.5 mm. A chip having such dimensions has already been realized in the Muchip (TM) of Hitachi, Ltd., for example, with dimensions of 0.4 mm in width, 0.4 mm in depth, and 0.1 mm in height. It is well known that it is technically possible to mass-produce and manufacture such an IC chip 8.

  Moreover, if the label base material 2 itself is brittle, when trying to peel off the label base material 2 attached to the adherend, the label base material 2 is Easily breaks. Therefore, it is possible to prevent the label substrate 2 from being peeled off while maintaining the form of the label substrate 2 as it is.

  Further, even if the seal label is to be duplicated by color copy or the like, since the security function layer 1 is provided, it is possible to prevent duplication of the same original as the original.

  Examples of the present invention will be described below. A hologram was formed as the security layer 1 on the TAC film serving as the substrate. This hologram was first coated and formed with an embossed layer having a thickness of 0.8 μm by a gravure printing method. Next, a nickel mold having a fine concavo-convex diffraction grating pattern is heated to 165 ° C. and pressed onto the emboss layer by a roll embossing method. A pattern was formed. Subsequently, a hologram was produced by depositing aluminum on the diffraction grating pattern with a thickness of 80 nm by vacuum deposition. Further, a heat detection layer 6 and a solvent coloring layer 7 were provided.

After that, as the adhesive layer 3 containing a magnetic substance, iron oxide (trivalent) (100 parts) as magnetic powder was mixed with BPS5160 (50 parts) manufactured by Toyo Ink Manufacturing Co., Ltd., and converted into an ink. An adhesive layer 3 containing a body is provided in a pattern, and an adhesive layer 5 not containing a magnetic substance is provided in a negative-positive relationship with the adhesive layer pattern containing the magnetic substance, and a release paper 4 is attached, and cut into a predetermined size. The anti-counterfeit seal 10 with the anti-replacement function was obtained.

  This was affixed to a box containing the product. When the label was verified with a magnetic verification machine after being attached, a magnetic output was obtained in a specific pattern, and it was confirmed that the label was genuine.

  Thereafter, the adhesive was carefully removed from the box while warming with a dryer. However, due to the presence of the heat detection layer, the peeled trace could be confirmed. Further, even if the adhesive layer is dissolved carefully with a solvent, the label color is changed due to the presence of the solvent coloring layer, and the trace of peeling can be confirmed.

  Furthermore, using a blade such as a cutter, the label was carefully peeled off from the box and affixed to another box again. In this case, since there is no particular change visually, it cannot be visually confirmed that it has been reused. However, when the label was verified with a magnetic verification machine, magnetic output was obtained in a pattern different from the first, and the traces once peeled off could be confirmed.

  A forgery prevention seal 10 with an anti-replacement function was produced in the same process as in Example 1, and further provided with notches and perforations as shown in FIG. Notches and perforations were provided and affixed to a box containing the product. While using a solvent for the anti-counterfeiting seal 10 with anti-replacement function or heating it with a dryer, we tried to remove it carefully from the box. It became difficult.
