Description

  The present invention relates to a non-contact information medium and a booklet with a non-contact information medium.

  In recent years, as systems using non-contact type IC cards and non-contact type IC tags have become widespread, for example, a booklet such as a passport or a savings passbook has an IC inlet comprising a non-contact type IC chip and an antenna coil connected thereto. Electronic data that is a non-contact type information medium sandwiched between base materials, a non-contact type information medium and a cover member using a cover cloth, etc. are bonded together, and an inner-attached paper and a body paper are attached and bound. A booklet with a non-contact type information medium capable of entering and printing is developed and publicly known.

  As an example of such a booklet with a non-contact type information medium, a concave portion is formed by bonding a second base material having an opening of a predetermined width on the upper surface side of the first base material. A non-contact type information medium having an IC chip and an antenna coil connected to the IC chip and having an adhesive layer provided on the lower surface side of the first base sheet is attached to the inner surface of the back cover. A booklet with a contact type information medium is known (for example, see Patent Document 1).

  Commonly distributed credit cards and IC cards are made of thermoplastic substrates such as polyvinyl chloride (PVC) and PET-G (polyester resin produced by terephthalic acid and ethylene glycol with a certain content of ethylene glycol). An IC chip, an antenna coil or the like is sandwiched between base materials such as a modified polyester resin substituted with cyclohexanedimethanol, and a strong heat pressure is applied to make the base material flow and smooth.

In addition, not only cresyl Ttokado and IC card, proof of such printed matter or a driver's license or passport, such as bank notes and securities, it is necessary to prevent the forgery and falsification in advance from those who use illegally. However, taking an electronic passport, which is one of the booklets with contactless information media, as an example, many counterfeits and alterations have been reported, and a function to prevent forgery and alteration has been added to the booklet to prevent these counterfeits. It is required to make it.

  In order to prevent the counterfeiting of the booklet, a commonly used anti-counterfeiting technique can be used. For example, ink (OVI) whose color changes depending on the viewing angle, or UV that reacts to ultraviolet light. It is also possible to print fluorescent ink or the like, insert a special fluorescent thread on the paper itself, or insert a security thread.

  In recent years, for example, printing of infrared absorbing ink having an absorption peak at a special wavelength has been performed in order to discriminate falsification by machine detection (see, for example, Patent Documents 2 and 3).

  Furthermore, taking a passport that requires personal authentication as an example, the data page may be laminated with, for example, a hologram film or personalized by laser engraving in order to prevent personal information such as names and facial photographs from being altered. Individual information can be recognized visually by recording information.

  By using PVC or PET-G as the base material for non-contact type information media and confining the IC chip or antenna coil inside, it can be made resistant to external influences such as moisture and chemicals. There is a problem that the rigidity is too high to be formed as a booklet.

  Therefore, by using a porous thermoplastic sheet instead of PVC or PET-G, it becomes possible to produce a non-contact type information medium rich in flexibility. However, the porous thermoplastic sheet has pores in the sheet, so it has good adhesion to various types of adhesives, but it is easy for moisture and various ions to penetrate from the outside, so it can penetrate inside. There is a need to suppress this.

  In addition, many non-contact information media such as IC cards require personal authentication, but there is no end to those who perform falsification, impersonate the owner and use it illegally. Since the person who performs the authentication check is not always trained in the method of identifying, it is required to accurately and easily determine the authenticity while improving the security.

  Furthermore, the conventional technology has a problem that forgery / alteration is easily performed, traces of forgery / alteration are difficult to remain, and it is difficult to determine authenticity. For such situations, the conventional anti-counterfeiting technology as described above basically prevents counterfeiting of printed materials based on paper, such as banknotes, securities, and passport booklets. Thus, it is less effective for alteration such as replacing a non-contact type information medium.

  In addition, the color material used for the falsification prevention mark is not an infrared absorbing ink having a wide absorption in the near infrared, but an infrared light at the time of machine detection is selected by selecting a color material that absorbs only light of a specific wavelength. Absorption occurs only when irradiating and the contrast of the monitor of the inspection machine changes and can be detected. Because it does not absorb light even when irradiating light other than a specific wavelength, contrast is not generated on the monitor of the inspection machine, and the falsification prevention mark is not recognized. Therefore, it generally absorbs all light in the near infrared region. Thus, it is possible to check traces of counterfeiting without being confused with carbon black, and to easily and quickly determine the authenticity of counterfeit products while maintaining high security of individual authentication. The infrared absorbing ink is preferably one that exhibits absorption of infrared wavelength light at least in the region of irradiation light used for mechanical detection and exhibits transmission in other infrared wavelength regions.

The perspective view which shows typically the booklet with a non-contact-type information medium which concerns on embodiment of this invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal side view schematically showing a configuration of a non-contact information medium of a booklet with a non-contact information medium according to an embodiment of the present invention. 1 is a longitudinal side view schematically showing a configuration of a cover of a booklet with a non-contact information medium according to an embodiment of the present invention. The conceptual diagram for demonstrating the non-contact-type information medium which gave the forgery and alteration prevention mark which concerns on embodiment of this invention.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a booklet 1 with a non-contact type information medium according to an embodiment of the present invention. A non-contact type information medium 4 is disposed between a cover member 2 and an inner sheet 3 attached to the inner surface thereof. Is formed by attaching a plurality of body sheets 6 to a cover sheet 5 embedded and formed.

As shown in FIG. 2, the non-contact type information medium 4 is mainly composed of an IC inlet 7. That is, the IC inlet 7 includes an antenna sheet 8, an antenna coil 9, and an IC chip 10. The antenna coil 9 is formed on the antenna sheet 8 by an etching method, a wire bonding method, a printing method, or the like. 9, an IC chip 10 is connected by a welding method or the like.
The form of the IC inlet 7 shown in FIG. 2 is an example, and the present invention is not limited to this form.

  The IC inlet 7 is disposed (clamped) between a plurality of (two in this example) base materials 11. A non-contact type information medium 4 is manufactured by laminating an adhesive layer 12 which is a layer for bonding the base material 11 on each inner side of the base material 11 and thermocompression bonding.

Further, in order to provide water resistance and ion resistance, a thin film coated with an adhesive constituting the adhesive layer 12 as a protective layer 13 is placed between the antenna coil 9 side of the antenna sheet 8 and the upper substrate 11. It is adhered by sandwiching and crimping. At this time, when thermocompression bonding is used, it is necessary to select a heat resistant film as the protective layer 13.

  The IC inlet 7 including the antenna sheet 8, the antenna coil 9, and the IC chip 10 includes the thickness of the IC chip 10 itself, the thickness of the antenna coil 9, the junction between the jumper wire and the antenna coil 9, and the antenna sheet 8 itself. Depending on the thickness, the sheet is uneven.

  When the IC inlet 7 is sandwiched between the base materials 11 and processed into the non-contact type information medium 4, it is desirable to eliminate these irregularities in appearance. For this reason, a hole 14 for accommodating the IC chip 10 is provided in the lower substrate 11 so that the IC chip 10 can be accommodated in the hole 14.

And as shown in FIG. 3, the cover member 2 is adhere | attached on the outer side of the non-contact type information medium 4 via the hot-melt layer 15, and the cover 5 of the booklet 1 with a non-contact type information medium is produced. . As an actual work, after attaching the text sheet 6 to the inner sheet 3, the inner sheet 3 is bonded to the non-contact type information medium 4 to which the cover member 2 is bonded via the adhesive layer 12.

Examples of the substrate 11 include polyvinyl chloride (PVC) and PET-G (modified polyester resin in which a certain content of ethylene glycol is replaced with cyclohexanedimethanol in a polyester resin produced by terephthalic acid and ethylene glycol), polyethylene In addition to smooth sheets such as polyolefin, polyester, polycarbonate, polystyrene, etc., these resins are used alone or in combination, and porous particles such as silica are mixed, foamed with air during mixing, stretched, etc. A porous thermoplastic sheet in which holes and dents are processed in a resin sheet can be used by performing drilling later.
Such a porous thermoplastic sheet is generally marketed as a resin sheet or synthetic paper imparted with printability for ink jet or offset.

  By using a porous thermoplastic sheet for the base material 11, it becomes possible to form a flexible non-contact type information medium 4 and to obtain good adhesion to the adhesive layer 12. Excellent in properties.

  When using a porous thermoplastic sheet for the base material 11, as shown in FIG. 2, a thermoplastic adhesive layer 12 is applied and formed in advance on the inner portions of the two base materials 11, and hot pressure is applied. To obtain a non-contact type information medium 4.

  Here, thermoplastic materials that can be used for the adhesive layer 12 include ethylene-vinyl acetate copolymer system, ethylene-methacrylic acid copolymer system, polyester system, acrylic system, nylon system, polyamide system, polyurethane system, polyolefin system, and the like. Various general thermoplastic resins can be used.

  Among these, for the adhesive layer 12, when a resin that forms a coating film that is particularly resistant to moisture and suppresses permeation of oxygen and chloride ions is selected, the IC inlet 7 is further protected from moisture and ions entering from the outside. This leads to an improvement in the effect. In order to make this performance compatible, two or more kinds of resins can be mixed and used. For example, an ethylene-methacrylic acid copolymer adhesive added with an epoxy cross-linking agent, a polyolefin-based, acrylic-based adhesive, etc. with a gravure method, offset method, inkjet method, etc. Can be obtained.

  In addition, when using an aqueous heat sealant made into an emulsion or dispersion using the above-mentioned resin, it is necessary to pay attention to whether the heat sealant itself has an adverse effect on the antenna coil or the like.

  On the other hand, in general, a polyester-based adhesive may be hydrolyzed by humidity, and an ethylene-vinyl acetate system is likely to be posted and deteriorated, so care must be taken.

  For the protective layer 13, it is necessary to select a film that is particularly resistant to moisture and suppresses the permeation of oxygen and chloride ions, and uses a layer that does not deteriorate due to heat or humidity. For example, a general film such as acrylic, nylon, polyethylene terephthalate, polyethylene, polyester, polycarbonate, acetylcellulose, polypropylene, polystyrene, and polyurethane may be used. However, in order to provide convenience when used as a booklet process or booklet, it is necessary to maintain flexibility, so it is necessary to use a thin layer film, and a film with a thickness of 4 μm to 25 μm is required. The thickness is particularly preferably 10 μm or less.

Further, as shown in FIGS. 3 and 4, a falsification preventing mark 16 is provided. The forgery / alteration prevention mark 16 is applied to the antenna sheet 8, the base material 11 coated with the adhesive constituting the adhesive layer 12 , and the protective layer 13 by an ink jet method, screen printing, or the like. ). In some cases, forgery and alteration prevention marks 16 may be provided at a plurality of locations, and the forgery and alteration prevention marks 16 may be intermittent symbols or characters.
Note that the form of the forgery and alteration prevention mark 16 shown in FIGS. 3 and 4 is an example, and the present invention is not limited to this form.

  The material of the infrared absorbing ink used for the falsification preventing mark 16 needs to exhibit absorption at least in the wavelength range of machine reading. For example, cyanine, pyrylium, thiopyrylium, squarylium, croconium, azurenium, and other polymethine dyes, phthalocyanine dyes, naphthalocyanine dyes, dithiol metal complex dyes, naphthoquinone dyes, anthraquinone dyes, triphenyl In addition to organic dyes such as methane dyes, aluminum dyes, and diimmonium dyes, metal oxides and metal hydroxides can be used.

Subjected to non-contact type information medium preventing falsification marks 16 to 4, when confirmed by inspection machine equipped with a monitor, symbols and concealed on the monitor emerge. Since the infrared absorbing ink and wavelength are specified, security is high, and the inspection method can be judged whether it is a fake product by checking the marking position and the shape of the pattern. If you check with an inspection machine without a monitor, you can check the presence of marking, but you cannot check the shape. Therefore, it is also possible to select the type of inspection machine according to the security level.

  If the IC inlet 7 is forcibly removed for falsification, the heat-laminated non-contact information medium 4 is peeled off between the adhesives. However, since the anti-counterfeit prevention mark 16 is provided, the pattern of the anti-counterfeit prevention mark 16 integrated when it is peeled off is deformed and cannot be restored to the original state. The peeled trace remains not only on the IC inlet 7 but also on the substrate 11 side and the protective layer 13 side, so that it cannot be reused in all layers, so that a highly secure non-contact type information medium 4 is obtained. It becomes possible.

  Further, the booklet 1 with the non-contact type information medium is formed by binding the non-contact type information medium 4 between the cover member 2 and the inner sheet 3 to form the cover sheet 5 and binding the text sheet 6 together. It is processed into a booklet shape.

Although the non-contact type information medium 4 is adhered by the adhesive layer 12 and the inner bonding sheet 3, in many cases to use emulsion adhesive aqueous from the side surface of the workability and the environment in the adhesive layer 12 used here, also Actually, in many cases, the equipment that has been used to manufacture booklets is often used, so an adhesive for bonding cloth and paper has been selected.

  If the non-contact type information medium 4 used for the booklet 1 with the non-contact type information medium is prepared using an exterior base material used for a general IC card, for example, PVC or PET-G, The inner sheet 3 cannot be bonded with equipment and an adhesive, and a problem arises due to high rigidity.

To solve such a problem, the use of the porous thermoplastic sheet over preparative as the base material 11, shows the different types of adhesives and good adhesion, and no irregularities, flexible non A booklet 1 with a contact information medium can be created.

  As the hot melt layer 15 for bonding the non-contact type information medium 4 and the cover member 2, a reaction-curing type adhesive having no volume change can be suitably used. If a dry-curing type adhesive having a volume change is used, if a part of the non-contact type information medium 4 is recessed, the amount of the adhesive used is increased, resulting in a large volume reduction during drying. Since a dent is generated on the outer side of the cover member 2, there is a problem in appearance.

  In order to solve such a problem, it is desirable to use an adhesive having no volume change. For example, a two-component mixed epoxy adhesive, a moisture curable silicone adhesive, a one-component curable urethane adhesive Etc. can be used. Various hot melt adhesives such as ethylene-vinyl acetate copolymer system, ethylene-methacrylic acid copolymer system, polyester system, polyamide system, polyurethane system, and polyolefin system can also be used.
