Description

  The present invention is applicable to various products such as health insurance insured cards, employee cards, employee cards, membership cards, student cards, cash cards, securities, alien registration cards and various licenses, brand products, etc. The present invention relates to a forgery-preventing display transfer sheet capable of performing anti-counterfeit display and a forgery preventing method using the same.

  In recent years, with the development of color copiers, it has become possible to make sophisticated copies that are difficult to distinguish from the real ones. For example, forgery of securities, checks, banknotes, etc. has occurred. These forged printed materials can be easily identified as flaws by skilled appraisers and special appraisers, but there are many types of securities and the like that are widely distributed and handled by ordinary people. For this reason, it is not practical means to rely on a skilled appraiser or a special appraisal device for authenticity determination of all securities and the like, and it is desired that ordinary people can easily and instantly determine.

In view of this, there has been proposed a printed material that can appear and be erased by changing the observation angle of a part of the visibility image (see, for example, Patent Document 1 below). In the printed matter, a part of the visibility image is an image made of only the glitter ink, and the other part is an image made of the black ink and the glitter ink having a small color viewing angle dependency. The printed matter of Patent Document 1 uses the reflection effect of the glitter ink, and a portion composed only of the glitter ink appears and appears to be erased depending on the observation angle, so that a special device is required. Therefore, even if it is not an expert appraiser, authenticity determination can be performed instantly and easily.
JP 2000-37941 A

  However, in the printed matter described in the above-mentioned Patent Document 1, due to the reflection effect of the glitter ink, a part of the visibility image that appears only from the glitter ink appears and appears to be erased depending on the viewing angle. Yes, the only source of true / false discrimination is that the above part appears and appears to have disappeared.

  Therefore, for counterfeit products, there is a risk of mistaking the counterfeit product as a genuine product if it is printed with a similar appearance even if it is not the same technology. The fact is that the security effect is not so high. Moreover, since the said part is a bare state on a base material, when these images are rubbed with another thing, they may disappear or may be damaged. Moreover, since the technique of Patent Document 1 is based on printing an image for authenticating with a special ink on a base material, printing costs are high, and it is drastically for a large variety of small lot products. It is inevitable that the cost will increase. In addition, a security effect cannot be imparted to an object that is not suitable for printing the special ink. Under such circumstances, the subject of security is limited.

The visual effect of the angle-dependent film changes depending on the viewing angle, and the fluorescent printing layer emits fluorescence in the visible range in response to light having a predetermined wavelength. For example, when confirming the authenticity of an anti-counterfeit object, the user confirms that the visual effect differs depending on the angle viewed by the angle-dependent film, and irradiates light or electromagnetic waves of a predetermined wavelength, thereby Confirm that it emits fluorescence.

Thus, it has double authenticity determination means of the presence of the angle-dependent film and the presence of the fluorescent printing layer, and an extremely high security effect can be exhibited.
In addition, since the fluorescent printing layer side of the angle-dependent film formed by printing or the like is bonded to the forgery prevention object with a transfer adhesive, the fluorescent printing layer collapses again when the film is peeled off, and the original Since it becomes impossible to return to a state, a very high security effect can be provided.

  In the present invention, the angle-dependent layer is formed so as to cover at least the entire printing region of the fluorescent printing layer, and conceals the fluorescent printing layer under natural light by irregularly reflecting or interfering the transmitted light. Since the angle-dependent layer conceals the fluorescent print layer under natural light, the presence of the fluorescent print layer can be concealed under natural light, so that the user is not aware of the fluorescent print layer. be able to. In addition, the angle-dependent layer causes diffuse reflection or interference of transmitted light, so that the user can recognize that the printed material has been subjected to security processing and has excellent design.

In the present invention, the angle-dependent film conceals the fluorescent printing layer under natural light when the fluorescent printing layer is concealed under natural light by irregularly reflecting or interfering the transmitted light. Therefore, the presence of the fluorescent printing layer can be hidden under natural light, and the user can be prevented from being aware of the fluorescent printing layer. Further, the angle-dependent film causes diffuse reflection or interference of transmitted light, so that the user can recognize that the printed material has been subjected to security processing and is excellent in design.

  Next, the best mode for carrying out the present invention will be described.

  FIG. 1 shows a forgery prevention display transfer sheet 1 according to a first embodiment of the present invention. In the forgery prevention display transfer sheet 1, an angle-dependent film 4 is laminated on a base sheet 2 for peeling and removal via an easy-peeling layer 3, and the angle-dependent layer 7 and fluorescent light are laminated on the angle-dependent film 4. A printing layer 6 is formed, and a transfer adhesive layer 8 is further formed.

  As the base material sheet 2, a resin sheet such as a PET resin having a certain degree of heat resistance to withstand heating / pressurization at the time of thermal transfer described later is used. Moreover, since it is necessary to transmit the heat | fever at the time of a thermal transfer to the adhesive bond layer 8, a thickness of about 30 micrometers or less is used suitably.

  As the angle-dependent film 4, a transparent hologram film can be suitably used. This angle-dependent film 4 has a hologram effect in which the visual effect changes depending on the angle at which the reflection of light shines in rainbow colors by forming a metal deposition layer on a transparent film of transparent PET or PVC acrylic copolymer. (For example, hologram pattern film manufactured by Nippon Koban Co., Ltd.).

  As a material used as the base of the said base material sheet 2 and the angle dependence film 4, it is not limited to what was mentioned above, Various things can be used. For example, a single-layer plastic film made of polyethylene, polypropylene, polystyrene, vinyl chloride resin, vinylidene chloride resin, a laminate film of a plurality of plastic films, and the like can be given. Among these, polyester, particularly PET, can be suitably used because it is excellent in transparency, toughness, electrical insulation, and dimensional stability.

  The base material sheet 2 and the angle-dependent film 4 are laminated via an easy peeling layer 3. The easy release layer 3 is not particularly limited as long as the base sheet 2 can be easily peeled from the angle-dependent film 4. For example, it can form as a peelable resin layer coated with respect to the base material sheet 2, For example, an acrylic resin, a melamine resin, a vinyl resin, a olefin chloride resin etc. may be individual or mixed. Moreover, as the easily peelable layer 3, the structure which gives the surface of the base material sheet 2 silicon coating and PTFE coating in order to improve peelability more may be sufficient. Further, for example, carnauba wax which is a plant wax, tree wax, cucumber wax, esvall wax, beeswax which is an animal wax, insect wax, shellac wax, whale wax, petroleum wax, etc. And waxes such as paraffin wax, microcrystal wax, polyethylene wax, ester wax, acid wax, and mineral wax such as montan wax, ozokerite, and ceresin.

  The fluorescent printing layer 6 is obtained by printing predetermined information on the angle-dependent film 4 using fluorescent ink that emits fluorescence in the visible range in response to light having a predetermined wavelength.

  As the fluorescent ink, fluorescent dyes, fluorescent pigments, and the like that emit fluorescence when irradiated with light of a predetermined wavelength such as ultraviolet light or electromagnetic waves, such as black light (invisible light), can be used. In this embodiment, a fluorescent pigment (black light pigment) that emits fluorescence when irradiated with ultraviolet rays is employed. Thus, the predetermined information printed by the fluorescent printing layer 6 cannot be visually recognized under natural light, but can be visually recognized by irradiating light of a predetermined wavelength such as black light. Here, the predetermined information is, for example, the characters “True” indicating genuine products (see FIG. 4).

  The angle-dependent layer 7 is formed of an angle-dependent ink that changes the color of reflected light depending on the viewing angle with respect to the angle-dependent film 4 on which the fluorescent printing layer 6 is printed.

As the angle-dependent ink, a metallic pigment, a pearl pigment, or the like can be used. In this embodiment, a pearl pigment is used. As the pearl pigment, a metal oxide that gives the mica reflectivity (high iris reflection) is coated with a metal oxide that is transparent in the visible range and has a refractive index of 2.0 or more. For example, Sb ₂ S ₃ , Fe ₂ O ₃ , PbO, ZnSe, CdS, Bi ₂ O ₃ , TiO ₂ , PbCl ₂ , CeO ₂ , Ta ₂ O ₅ , ZnS, ZnO, CdO, Nd ₂ O ₃ , Sb ₂ O ₃ , SiO and InO ₃ It is formed by coating a single layer or two layers.

  When mica and metal oxide film are combined, the difference in refractive index is larger than 0.4, so the amount of incident white light is reflected, and at the same time, it causes secondary refraction at the interface between mica and metal oxide film. Therefore, it becomes highly iris reflective and works to promote the discoloration effect more effectively. At this time, the film thickness of the metal oxide film covering the mica can be controlled to obtain a pearl pigment having a high rainbow reflectivity of any color tone. The film thickness is 10 to 10000 angstrom, preferably 200 to 2000 angstrom. A film thickness in the range is desirable because it is highly iris reflective to the visible range.

  Examples of such commercially available pearl pigments include “Iriodin” (trade name, manufactured by MERCK). “Iriodin” is a stable inorganic pearl pigment in which the surface of natural mica is coated with a metal oxide having a high refractive index such as titanium oxide and iron oxide, and a layer of titanium oxide having a high refractive index and a mica having a low refractive index and The light reflected at the boundary with the surrounding medium brings about pearl luster. In this “Iriodin”, the specific color of the iris can be emphasized by changing the film thickness of the coated titanium oxide. In addition, ink is used.

  In addition, the pearl pigment may be a gold type or a silver type.

  Thus, when the angle-dependent layer 7 is formed of angle-dependent ink, the color on the surface of the forgery prevention display 11 varies depending on the viewing angle, which is effective for security confirmation. In addition, since the color of the reflected light with respect to the angle-dependent layer 7 changes depending on the viewing angle, it looks shining for the user, so that the design as a whole can be improved.

  The angle-dependent layer 7 is formed so as to cover at least the entire printing region of the fluorescent printing layer 6, and conceals the fluorescent printing layer 6 under natural light by causing irregular reflection or interference of transmitted light. ing. By doing in this way, since the angle dependent layer 7 conceals the fluorescent printing layer 6 under natural light, the presence of the fluorescent printing layer 6 can be concealed under natural light. Can be prevented from being conscious of the user. Further, the angle-dependent layer 7 diffuses or reflects the transmitted light, so that the user can recognize that the printed material has been subjected to security processing and has excellent design.

  In addition to the angle-dependent layer 7 or in place of the angle-dependent layer 7, a concealing layer that conceals the fluorescent printing layer 6 under natural light can be formed by irregularly reflecting or interfering the transmitted light. This concealing layer may be a layer in which minute irregularities are formed. For example, it can be realized by processing such as matte (matte) finish or texture finish that forms textured irregularities. In addition, the concealing layer may be a single-layer plastic film made of PET, polyethylene, polypropylene, polystyrene, vinyl chloride resin, vinylidene chloride resin, etc., which has an irregular surface formed by processing such as the mat finish, and a plurality of such films. It may be a transparent film such as a laminate film of a plastic film.

  The angle-dependent film 4 conceals the fluorescent printing layer 6 under natural light by irregularly reflecting or interfering the transmitted light. Thereby, since the angle-dependent film 4 conceals the fluorescent printing layer 6 under natural light, the presence of the fluorescent printing layer 6 can be concealed under natural light. It can be made unconscious. In addition, the angle-dependent film 4 diffuses or reflects the transmitted light, so that the user can recognize that the printed material has been subjected to security processing and has excellent design.

  A hot-melt adhesive layer 8 is formed on the side of the angle-dependent film 4 on which the angle-dependent layer 7 and the fluorescent printing layer 6 are formed.

  As the transfer adhesive for forming the adhesive layer 8, for example, a hot-melt transfer adhesive (hot melt adhesive) can be used. By using a hot melt adhesive, it becomes possible to display forgery prevention by thermal transfer. Further, as the transfer adhesive, an adhesive for water transfer or an adhesive for pressure transfer can be used.

  FIG. 2 shows an anti-counterfeit display method using the transfer sheet 1 for anti-counterfeit display.

  First, as shown in FIG. 2A, the adhesive layer 8 of the anti-counterfeit display transfer sheet 1 is brought into close contact with the anti-counterfeit object 10, and the hot stamp 9 is attached to the anti-counterfeit display transfer sheet 1 in this state. The substrate sheet 2 is brought into close contact with pressure and the forgery prevention display transfer sheet 1 is heated and pressurized. As a result, the adhesive layer 8 in the region heated by the hot stamp 9 is melted and adhered to the forgery prevention target object 10, thereby forming the adhesive layer 8a.

  Next, as shown in FIG. 2B, when the hot stamp 9 is removed and the transfer sheet 1 for forgery prevention display is removed after the adhesive of the adhesive layer 8a is cured, the region heated and adhered by the hot stamp 9 is removed. The base sheet 2 is removed from the easily peelable layer 3, and the angle-dependent film 4, the angle-dependent layer 7, and the fluorescent printing layer 6 are thermally transferred to the forgery prevention target object 10.

  FIG. 3 shows an example in which the angle-dependent film 4, the angle-dependent layer 7, and the fluorescent printing layer 6 are thermally transferred to the forgery prevention target object 10 and the forgery prevention display 11 is applied. As described above, the forgery prevention display 11 can be easily given to any part of the forgery prevention target object 10 by thermal transfer.

  FIG. 4 is a diagram for explaining the operation of the forgery prevention display 11 formed as described above. As shown in FIG. 4A, under normal natural light, the angle-dependent layer 7 hides the fluorescent printing layer 6 so that the fluorescent printing layer 6 cannot be visually recognized. However, as shown in FIG. As described above, when the black light 13 is irradiated with ultraviolet rays or the like having a predetermined wavelength, the fluorescent printing layer 6 emits fluorescence, and the fluorescent characters 12 emerge. Thereby, authenticity can be determined easily.

  As described above, in the first anti-counterfeit display transfer sheet 1, the angle-dependent film 4 is laminated on the base sheet 2 via the easily peelable layer 3, and the angle-dependent layer is compared with the angle-dependent film 4. 7 and the fluorescent printing layer 6 are formed, and a hot-melt adhesive layer 8 is further formed. And the 1st forgery prevention method uses the said forgery prevention display transfer sheet 1, and thermally transfers the said angle dependent film 4, the angle dependent layer 7, and the fluorescence printing layer 6 with respect to the forgery prevention target object 10. FIG. The forgery prevention display 11 is performed.

  Thereby, the angle dependent layer 7 and the fluorescent printing layer 6 are adhered to the forgery prevention target object 10, and the angle dependent film 4 is further adhered thereon. The visual effect of the angle-dependent film 4 changes depending on the viewing angle, the color of the reflected light changes depending on the viewing angle of the angle-dependent layer 7, and the fluorescent printing layer 6 responds to light of a predetermined wavelength. Fluoresce in the visible range. For example, when confirming the authenticity of the forgery prevention target object 10, the user confirms that the visual effect varies depending on the angle viewed by the angle-dependent film 4, and the color changes depending on the angle viewed by the angle-dependent layer 7. Then, it is confirmed that the fluorescent printing layer 6 emits fluorescence by irradiating light of a predetermined wavelength or electromagnetic wave. If any one of these cannot be confirmed, it can be easily determined that the forgery prevention target object 10 is a forgery product. In this way, the presence / absence of the angle-dependent film 4, the presence of the angle-dependent layer 7, and the presence of the fluorescent printing layer 6 are provided with triple authenticity determination means, and an extremely high security effect can be exhibited.

  Moreover, the angle-dependent film 4 in which the angle-dependent layer 7 and the fluorescent printing layer 6 are formed by printing or the like is bonded to the anti-counterfeit object 10 by the hot-melt adhesive layer 8 on the side of the angle-dependent film 7 and the fluorescent printing layer 6. For this reason, if the angle-dependent film 4 is peeled off, the angle-dependent layer 7 and the fluorescent printing layer 6 are broken and cannot be restored to the original state, so that an extremely high security effect can be provided.

Further, the anti-counterfeit display 11 is covered with the angle-dependent film 4 which is the transparent film, and the angle-dependent layer 7 and the fluorescent printing layer 6 can be prevented from being stained or deteriorated. . Further, the forgery prevention display 11 can be easily displayed on any object by thermal transfer using an existing thermal transfer apparatus, and therefore can provide a security effect at an extremely low cost. In addition, a security effect can be imparted to a large variety of small lot products without a significant cost increase compared to a printing method or the like.

  FIG. 5 shows a first example of the forgery prevention display transfer sheet 1 of the second embodiment of the present invention. The transfer sheet 1 for forgery prevention display has an angle-dependent layer 7 and a fluorescent printing layer 6 formed on the base sheet 2 via an easy peeling layer 3, and further has an adhesive layer 8 for transfer. It is configured.

  As the base material sheet 2, the easily peelable layer 3, the angle-dependent layer 7, the fluorescent printing layer 6, and the adhesive layer 8, the same materials as those in the first embodiment are used.

  FIG. 6 shows a forgery prevention display method using the transfer sheet 1 for preventing forgery display.

  First, as shown in FIG. 6A, the adhesive layer 8 of the anti-counterfeit display transfer sheet 1 is brought into close contact with the anti-counterfeit object 10, and the hot stamp 9 is attached to the anti-counterfeit display transfer sheet 1 in this state. The substrate sheet 2 is brought into close contact with pressure and the forgery prevention display transfer sheet 1 is heated and pressurized.
