Description

  The present invention relates to an information recording body (passbook, passport, license, various certificates, etc.) formed by transferring an intermediate transfer medium to a base material made of paper or plastic. Provided are an information recording transferred body having good security against tampering or alteration, a manufacturing method thereof, and an information recording body.

  Information recording bodies are widely used as various certificates such as licenses and passports in which information such as images and letters is written in card shape or booklet shape, and as means for creating this information recording body by thermal transfer There is a type in which an intermediate transfer medium formed and supported with information such as images and characters is transferred and formed on an information recording transfer target composed of a base material.

  The heat transferable intermediate transfer medium used for the production of the information recording medium is a support on which a release layer, an intermediate layer, an adhesive layer, etc. are sequentially provided as a transfer layer from the support side. It is a medium that is superimposed on a substrate of a recording transfer target, is pressed, and is transferred to the substrate by receiving heat from either the support side or the substrate side.

  A peeling layer is a layer provided in order to implement | achieve these favorable peeling, when the interface of a support body and a transfer layer does not peel well at the time of transcription | transfer by the compatibility of each material. In the present invention, the release layer is not essential. The intermediate layer is a layer existing between the adhesive layer and the release layer and may be appropriately designed as necessary. For example, a layer for improving the adhesive force between the two, a layer for preventing forgery and improving decorativeness, and a layer for preventing forgery and improving decorativeness, for example, an OVD having a diffraction structure. A forming layer.

The adhesive layer is a layer that adheres to the substrate by heat and pressure, and can be an image receiving layer and adhesive layer that also serves as an image receiving layer that forms information such as images and characters with a heat transfer material. The image receiving layer / adhesive layer is a layer having an image receiving ability capable of recording image information (including characters, symbols, etc.) without a printing plate by a printing technique such as a thermal transfer printer or an ink jet printer. It is possible to provide an image with a dye or pigment before transfer of the transfer medium.

  As a method for forming information on the image receiving layer / adhesive layer, the intermediate transfer medium is transported to a transfer device comprising the main part of the drum and the thermal head, and the color material of the transfer ribbon is a heat transfer material. The layer is brought into contact with the image receiving layer / adhesive layer of the intermediate transfer medium, the thermal head is pressed from the transfer ribbon side, and the heating element group of the thermal head is appropriately heated on the basis of the image data, thereby generating the image data. An image pattern based thereon is formed and printed on the image receiving layer / adhesive layer. When the image data is multicolored, a transfer ribbon having a different color tone or a transfer ribbon having a color material layer having a different color tone is applied, and the same process is repeated to obtain a multicolor image on the image receiving layer / adhesive layer. A pattern is formed.

  The OVD formation layer is intended for decorativeness and forgery prevention. For example, an OVD formation layer on which a relief hologram composed of a fine concavo-convex pattern is formed, and an OVD formation provided along the fine concavo-convex surface. In this way, an intermediate transfer medium using a relief hologram as the intermediate layer is manufactured in large quantities at a low cost by the emboss replication method. It is often used because dead copy is difficult.

  As an example of the transfer method, the adhesive layer or the image receiving layer / adhesive layer of the intermediate transfer medium is brought into contact with the substrate which is the transfer medium, and a heating roll, a hot plate or the like is heated from the support side of the intermediate transfer medium. The medium is pressed and heated to a transfer temperature to press the adhesive layer onto a substrate that is a medium to be transferred, and the support is peeled from the intermediate transfer medium to obtain an information recording body.

  In addition, as described above, when the base material that is the transfer medium and the image receiving layer / adhesive layer of the intermediate transfer medium are bonded, the adhesive property is not good depending on the material of the base material. There is a case in which an information recording transfer object having improved adhesion by forming an easy adhesion layer is prepared.

As described above, an information recording body using a conventional intermediate transfer medium (for example, see Patent Document 1) is used as an information recording body having a high effect of preventing forgery and alteration.
However, in the above information recording medium, there is a possibility of unauthorized use by peeling off the intermediate transfer foil on the surface by using heat or chemicals and altering the recorded information. Further, in the information recording medium modified in this way, there is a problem that the trace of the modification is difficult to remain and it is difficult to discriminate.
In order to solve this problem, for example, a method of mixing a phosphor in an easy-adhesion layer can be used. In this case, the entire surface of the information recording body emits fluorescence uniformly, so that forgery is easy. become. On the other hand, when an image is formed with a plate using halftone dots when printing the easy-adhesion layer, the adhesion of the transfer layer is maintained in a portion where the halftone dot density of the easy-adhesion layer is high. There is a problem that a portion where the easy-adhesion layer does not exist occurs in the portion having a low concentration, and the adhesion of the transfer layer in the portion becomes extremely weak.

Prior art documents are shown below.

  Embodiments of the present invention will be described in detail with reference to FIGS.

  FIG. 1 is an explanatory side sectional view showing an embodiment of an information recording transfer medium and an intermediate transfer medium according to the present invention, and FIG. 2 is information in which a transfer layer is provided on an easy adhesion layer of the information recording transfer medium. It is side sectional explanatory drawing which shows one Example of a recording body. As shown in FIG. 1, the information recording transfer object (1) is formed from an information recording transfer object (1) comprising a base material (1A) provided with an easy adhesion layer (1B) containing a phosphor (not shown). Become. The intermediate transfer medium (2) comprises, for example, a support (2A) / peelable protective layer (2B) / intermediate layer (2C) / adhesive layer or image receiving layer / adhesive layer (2D). Also, the information recording body (3) in FIG. 2 is supported by bringing the adhesive layer or the image receiving layer / adhesive layer (2D) side of the intermediate transfer medium into contact with the easy-adhesion layer (1B) of the information recording medium. It is formed by removing the support after applying heat pressure from the body side, and the constitution thereof is, for example, in order from the top, peelable protective layer (2B) / intermediate layer (2C) / adhesive layer or image receiving layer / adhesive layer ( 2D) / easy adhesion layer (1B) / base material (1A). Hereinafter, each layer will be described.

  As materials used as the base material (1A), papers that are most effective for the present invention, polyethylene terephthalate, polyethylene naphthalate, polyvinyl chloride, polyester, polycarbonate, polymethyl methacrylate, polystyrene, and other synthetic resins are used. Films, etc. can be used alone or in combination.

  The resin that is the main component of the easy-adhesion layer (1B) is a resin that is compatible with the adhesive layer or the image receiving layer / adhesive layer (2D) of the intermediate transfer medium (2) and is a thermoplastic material such as urethane or acrylic. , Vinyl acetate, etc. can be used alone or in combination. The easy-adhesion layer (1B) in the present invention contains a phosphor (not shown) in these resins.

In order to form the easy adhesion layer containing the phosphor, for example, an ink in which a fluorescent pigment is dispersed in an emulsion of the resin can be prepared and formed on a substrate by screen printing or the like. For example, when a flat screen printing machine is used, printing is generally performed by the following structure and operation, which will be described below with reference to FIG. The printing machine includes a platform (4) on which a substrate is placed, a screen plate (5A), a squeegee (5B), and a doctor (5C). First, the base material (1A) is placed on the table (4), and the screen plate is placed on the base (4A) with a slight gap left therebetween. Next, ink (not shown) is put on a portion of the screen plate where there is no design, and the mesh portion is filled with ink by scraping the design portion so that it passes through the design portion. Thereafter, the ink of the mesh portion is transferred to the substrate by moving the squeegee and applying pressure. The pressure applied between the squeegee and the substrate at this time is called a printing pressure.
Normally, if the printing pressure is increased, more ink will be pushed out and the coating thickness will increase.However, if the printing pressure is partially increased extremely, the ink will move from the strong part to the peripheral part. Conversely, the coating thickness is reduced. By utilizing this principle, the thickness of the easy-adhesion layer can be partially changed, and the design can be expressed by the difference in thickness.

  For example, when a flat screen printing machine is used, the present invention forms a pattern by providing a thickness difference of the easy-adhesion layer by the following structure and operation. The configuration of the printing machine is the same as that of normal printing, and consists of a stand, a screen plate, a squeegee, and a doctor. On this stand (4), a design jig (6) is arranged (see FIG. 3). As shown in FIG. 4, a thin sheet (6A) or the like cut out in the form of characters can be prepared as the design jig placed on the platform. A sheet having a thickness of about 0.05 mm to 0.5 mm can be suitably used, but is not limited thereto. Instead of a sheet, a character or pattern (6B) created by bending a wire can be used. A wire having a thickness of about 0.05 mm to 0.5 mm can be suitably used. In addition, a concavo-convex pattern can also be formed with a thermoplastic resin, or a concavo-convex pattern can be formed by cutting. A base material is set on this, and printing is performed in the same manner as the above-described normal printing method. Since the base material in the portion where the sheet or wire is disposed is apparently thicker than the other portions, the pressure applied by the squeegee is concentrated, and the printing pressure is higher than in other portions. As a result, the thickness of the pattern part (7A and 7B) of the easy-adhesion layer applied to the base material (1A) where the sheet or wire is disposed is thinner than the other part (7C) (see FIG. 5). ). In addition to placing a simple mold on a table, it is possible to form a pattern using a fine relief plate or use a number printing machine. Furthermore, for example, in the case of a cylinder type screen printing machine, it is possible to obtain the same effect by adding an uneven pattern to the cylinder by the above-described method or by directly forming an uneven surface on the cylinder.

The printing pressure can also be changed depending on the shape of the squeegee. For example, if a part of the squeegee is cut into a shape that is recessed relative to the other parts, the printing pressure at that part becomes insufficient, and ink transfer to the substrate is reduced. On the other hand, when only a part of the squeegee is processed to be convex, the printing pressure at that part becomes extremely high, and the ink is pushed out to the periphery, so the thickness of the coating layer is reduced. , The periphery becomes thicker. In this way, the thickness of the coating layer can be changed by processing the squeegee, and, for example, a barcode or wave pattern can be formed by the difference in thickness.

  The phosphor contained in the easy-adhesion ink is excited by infrared light, visible light, or ultraviolet light, and emits light in the infrared wavelength region, visible wavelength region, or ultraviolet wavelength region. For example, an infrared phosphor that is excited by infrared light and emits light in a wavelength region longer than the wavelength, or an ultraviolet phosphor that is excited by ultraviolet light and emits light in the visible wavelength region is preferably used. In addition, a phosphor having a combination of excitation light and emission wavelength region other than those described above can also be used. By mixing these phosphors with the ink for the easy-adhesion layer, a pattern due to the difference in thickness of the easy-adhesion layer can be expressed as a pattern due to light emission of the phosphor. For example, a phosphor that is excited by ultraviolet light and emits light in the visible wavelength region is used by mixing it with easy-adhesive ink. In this case, when this information recording material is irradiated with ultraviolet light, a similar pattern can be visually confirmed by emitting light that is strong in the thick portion of the easy adhesion layer and weak in the thin portion. This technique can be used not only for visual confirmation but also when using a phosphor that emits light in various wavelength regions by using a verifier capable of detecting infrared light or the like.

  The support (2A) of the intermediate transfer medium (2) is a material having a higher melting or softening temperature than the material used for the adhesive layer or the image-receiving layer / adhesive layer (2D). For example, polyethylene terephthalate, polyethylene naphthalate A synthetic resin film such as phthalate, polyvinyl chloride, polyester, polycarbonate, polymethyl methacrylate, or polystyrene, or a composite of paper or synthetic paper alone or in combination thereof can be used.

  As the peelable protective layer (2B), the adhesive layer or the image receiving layer / adhesive layer (2D) is more effectively transferred to the transferred material, and the transferred adhesive layer or the image receiving layer / adhesive layer (2D) is transferred. Has a protective film function to prevent chemical and mechanical damage from the outside. For example, thermoplastic acrylic resin, chlorinated rubber resin, epoxy resin, vinyl chloride vinyl acetate copolymer resin, cellulose resin, chlorinated polypropylene resin, or Teflon (registered trademark) powder, polyethylene powder, animal wax, plant Waxes, mineral waxes, natural waxes such as petroleum waxes, synthetic hydrocarbon waxes, aliphatic alcohols and acid waxes, fatty acid esters and glycerite waxes, hydrogenated waxes, synthetic ketone waxes, amine and amide waxes Further, synthetic waxes such as chlorinated hydrocarbon waxes, synthetic animal waxes, and alpha-olefin waxes, and anti-friction agents such as metal salts of higher fatty acids such as zinc stearate can be used. Moreover, you may use an inorganic substance.

  As the intermediate layer (2C), a pattern layer (not shown), an OVD layer (not shown), or the like can be formed, and the pattern layer can be formed by a normal printing method such as gravure printing. The OVD layer includes a hologram forming layer (not shown) and a transmissive thin film layer (not shown), and the hologram forming layer is provided with a fine uneven pattern on the surface of the hologram forming resin layer. The resin must have good embossing formability, hardly cause press unevenness, obtain a bright reproduced image, and have good adhesion to the peelable protective layer (2B) and the permeable thin film layer. For example, thermoplastic resins such as polycarbonate resin, polystyrene resin, polyvinyl chloride resin, unsaturated polyester resin, melamine resin, epoxy resin, urethane (meth) acrylate, polyester (meth) acrylate, epoxy (meth) acrylate, polyol (meta ) Thermosetting resins such as acrylates, melamine (meth) acrylates, triazine (meth) acrylates or mixtures thereof, and thermoformable materials having radically polymerizable unsaturated groups can be used. Any material can be used as long as it is stable and capable of forming a hologram image. The transparent thin film layer is a transparent material for transmitting information of the hologram forming layer, and a higher refractive index than the hologram forming layer (refractive index n = 1.3 to 1.5) improves the decorativeness. preferable. Further, the transmissive thin film layer may be formed by superposing a plurality of layers, or may be a multilayer film in which layers having different refractive indexes are combined, or a layer having a high refractive index and a layer having a low refractive index are alternately stacked. . Further, as a method for forming such a thin film layer, film forming means such as sputtering and ion plating can be applied in addition to vacuum deposition, and the film thickness is in the range of 10 nm to 1000 nm. It is preferable. The hologram layer may be a volume phase hologram such as a Lippmann hologram, in addition to the so-called relief hologram.

  The adhesive layer or the image receiving layer / adhesive layer (2D) is used as a heat-sensitive adhesive, and examples thereof include vinyl chlorides such as vinyl chloride and vinyl acetate copolymers, linear saturated polyesters, and polyester polyamides. These are mainly thermoplastic resins such as polyester and acrylic.
