Description

The present invention relates to a medium (information display body) for displaying personal information such as a passport or an ID card, which uses a security label or the like attached to the surface of the medium (hereinafter referred to as a holopatch or simply a patch). The present invention relates to a technology for preventing the replacement or tampering of security articles such as a transfer foil and a transfer foil.

As a means for improving the security of information display bodies such as cards and passports, a method of sticking a film (hereinafter referred to as a security layer) containing a security element such as a hologram on a surface on which information is recorded is generally used. It is used.

Here, a relatively thick security layer having a thickness of 10 μm to 100 μm is referred to as a patch, and a thin security layer having a thickness of 1 μm to 10 μm is referred to as a transfer foil.

The patch is attached to the data surface of the passport or card through the adhesive layer and is used for protection thereof, and has high durability, but is weak against forgery/alteration that is peeled off and illegally reused.

On the other hand, since the transfer foil is thin, it is easily broken when peeled off and has high security. Therefore, the use in passports is increasing. However, since the durability is low, a transfer foil is rarely used and a patch is used particularly in cards that are often placed in an environment where they are rubbed.

Further, by providing an optical element using a hologram or a printing layer using a special ink on the patch or the transfer foil, it can be used as a security layer with higher security.

However, a relatively large optical element such as a microlens or a lenticular lens requires mechanical strength to some extent when forming, and therefore can be provided only in a patch.

There are also technologies such as brittle labels that prevent peeling and reuse. This is one in which two kinds of adhesive layers having different adhesive strengths are separately applied on a plane, and when peeled off, a part is peeled from the base material, but a part remains on the base material side. The brittle label, like the transfer foil, is relatively strong against forgery/alteration, but is inferior in durability against friction and is not suitable for an information display.

In the information display body to which such a security layer is attached, it is a big problem that the security layer is peeled off and reused illegally.

Since the patch often uses an adhesive, it can be peeled off by heating or the like. Even a transfer foil can be peeled off by backing it with a transparent tape for reinforcement.

Since it is difficult to prevent the security layer attached to the information display from being peeled off from the base material, as a countermeasure, it is possible to determine that a mark remains when peeled off, the security layer is destroyed, or it is reattached. Functions that are possible are required.

As an example of the technology most similar to the technology that realizes such a function, the patch serves as a protective layer and protects the surface of the anti-counterfeit medium even under severe use conditions such as repeated use many times. In addition to scratch resistance, solvent resistance, and the like, a technology relating to an anti-counterfeit medium having excellent security, which has a fluorescence-emitting hologram having excellent heat resistance and light resistance, is disclosed (Patent Document 1).

However, this technique is different from the technique of peeling off the security layer attached to the base material from the base material to prevent unauthorized use.

In this adjacent display unit, information is displayed across the information display layer on the security layer side and the information display layer on the base material side. That is, a part of the information is displayed on the information display layer on the security layer side, and the remaining part of the information is displayed on the information display layer on the adjacent base material side to display the information. In this manner, the information displayed on the information display layer on the security layer side and the information displayed on the information display layer on the base material side are combined in a plan view to form completed ID information and biometric information.

When displaying an image such as a character that is ID information completed in a planar view or a face that is biometric information, the information display layer on the security layer side displays a part of the character or image, and the information display layer on the base material side, Display the rest of the text or image. As a result, the completed character or image is displayed.

Further, the layer having an anti-counterfeiting function in the information display body of the present invention is any one selected from the embossed hologram, the crystalgram, the Lippmann hologram, the diffraction grating optical element, and the printed material of the printing ink, or any two. It may be composed of a combination of two or more.

Further, the information display layer may be a laser coloring layer.

Further, the information may be composed of either one or both of biometric information and ID information.

Next, an embodiment of the information display body of the present invention will be described in more detail with reference to FIGS.
FIG. 1 is an explanatory diagram illustrating an example of the information display body of the present invention.
FIG. 1A is a diagram of an example of the information display body 10 of the present invention viewed from above.
In the information display body 10 of the present invention, as shown in FIGS. 1(a) and 1(b), the base material 7 is a laminated layer including the laser coloring layer 6 formed between the resin layer 8 and the transparent resin layer 9. It may be the body. Further, the security layer 5 may be a laminated body including a laser coloring layer 6 ′ formed between the transparent resins 11 and 12.

The security layer 5 is provided inside the end of the base material 7, and is at least a transparent hollow patch using a hologram attached to the base material 7 such as an IC card or an ID card (security using a hologram. It may be a laminated body including a label (not shown) or a transparent hologram transfer foil (not shown) and a laser-drawable information display layer 6'.

In the information display layer 6 on the base material 7 side and the information display layer 6'on the security layer 5 side, the ID information and the biological information are provided at the end of the security layer 5 across the information display layer 6 and the information display layer 6'. When information such as information is displayed complementarily, the ID information 2 displayed as a completed character and the biometric information displayed as a completed image when viewed from the top of the information display body 10 (plan view). Either one of them or both of them are provided.

Here, “complementary” means complementing each other to complete one, and specifically, the ID information formed on the base material 7 side when viewed from the upper surface of the information display body 10 of the present invention. 2 and the ID information 2 formed on the security layer 5 side are complementary to each other along the edge of the security layer 5 to form a completed character string, like tally. ..

That is, a part of the ID information 2 formed on the information display layer 6 on the side of the base material 7 made of a laser coloring layer or other material provided along the end of the security layer 5 of the information display body 10 of the present invention. , The remaining ID information 2 formed on the information display layer 6'on the security layer 5 side and the completed ID information are displayed.

The completed ID information 2 is composed of a part of the ID information 2 displayed on the information display layer 6'and the remaining part of the ID information 2 displayed on the information display layer 6 adjacent thereto. Further, a part of the ID information 2 may or may not be displayed on the information display layer 6 at a position overlapping the information display layer 6'in a plan view.

With such a configuration, when the security layer 5 is peeled off, the information display 10 is provided on the information display layer 6 on the base material 7 side along the end of the security layer 5 on the base material 7 side. The displayed "remaining part of ID information 2" remains, and part of the ID information is missing. The "part of the ID information 2" remains on the information display layer 6'on the security layer 5 side. Therefore, when the security layer 5 is peeled off, it can be determined that the security layer is peeled off. The same applies to the biometric information 1.

The method of forming the ID information 3 and the biometric information 4 formed on the base material 7 is not particularly limited. For example, when forming the biometric information 1 and the ID information 2 together, a laser coloring layer is formed as the information display layer 6 at the position of the base material 7 on which the ID information 2 and 4 and the biometric information 1 and 3 are formed. Then, it may be formed using a laser marker or the like. If not formed at the same time, the biometric information 1 and the ID information 2 are formed by using a laser coloring layer and a laser marker, and the ID information 3 and the biometric information 4 are formed by using a card printer, an inkjet printer, or another printing method. Then, it may be formed. As the ink to be used, it is possible to use a special ink such as a fluorescent ink, an optically variable ink such as a pearl ink, as well as a commonly used printing ink.

Next, each component of the information display body 10 of the present invention will be described.

(Base material)
As the base material 7, various materials can be used according to the purpose of use of the information display body 10, but a material capable of laser drawing can be used. For example, it is preferable that the resin is provided with a laser-drawable information display layer 6 such as a transparent resin layer/laser coloring layer/transparent resin layer. With such a configuration, it is possible to prevent the information display layer 6 from being scraped off easily, and thus it is possible to prevent unauthorized forgery and falsification.

It is also possible to use metals such as stainless steel and titanium. It is possible to draw by irradiating the surface of these metal sheets with a laser beam to melt or change the color.

(Transparent resin layer and resin layer)
Polycarbonate can be preferably used as the transparent resins 9 and 12, but any resin can be used as long as the information display layers 6 and 6 ′ provided inside have a transparency that allows laser drawing. For example, PET (polyethylene terephthalate), PETG (glycol modified PET), vinyl chloride, etc. can be mentioned.
As the resin layer 8, the same resin as the transparent resin layers 9 and 12 can be used. The difference from the transparent resin layers 9 and 12 is that they are not necessarily transparent.

(Security layer)
The security layer 5 may be a holographic patch using a hologram or the like or a transfer foil, and there is no limitation on the thickness. Since it is assumed that laser drawing is performed after the security layer 5 is attached to the base material 7, laser light transmits through the security layer 5 and is drawn on the information display layers 6 and 6 ′ composed of a laser coloring layer or the like. It is preferable to have transparency as much as possible.

Further, the security layer 5 can include various forgery/alteration preventing functions. For example, an OVD (Optical Variable Device, an optically variable device) such as an embossed hologram, a crystalgram (registered trademark of Toppan Printing Co., Ltd.), a Lippmann hologram, or an OVI (Optical Variable Ink) such as a pearl ink on a resin layer. , An optically variable ink), an article printed with an ultraviolet coloring ink, or the like can be used.

(Information display layer)
As the information display layers 6 and 6', a laser coloring layer, an aluminum vapor deposition layer, an OVI printing layer, a pigment printing layer and the like can be preferably used. The information display layers 6 and 6'made of such a material must be provided at least along the end of the security layer 5 and across the security layer 5 and the base material 7.

As the laser coloring layer, any material can be used as long as it is a material that changes color when irradiated with laser light. Alternatively, the material may be removed to expose the base, and the color of the base may be exposed to develop color. Further, the surface roughness of the surface may be changed to have a reflectance different from that of the surroundings, so that characters or images may be displayed.

The information display layer using an aluminum vapor deposition layer (also referred to as an aluminum vapor deposition layer) removes the aluminum layer by irradiating the aluminum vapor deposition layer on the front side with laser light along the edge of the security layer, and Is exposed to display information.

The information display layer using the OVI print layer can be formed by screen-printing OVI on the base material.

The ID information 3 on the base material 7 side and biometric information such as a facial photograph may be printed using normal ink. However, it is preferable that the ID information 2 and the biometric information 1 formed across the end portion of the security layer 5 and the base material 7 are laser-drawable information displays.

Next, examples of the present invention will be described.

<Example 1>
First, a face photograph and ID information were printed on a PET substrate using a card printer CP500 (manufactured by Toppan Printing Co., Ltd.).
Next, a security hologram (hereinafter referred to as a “holopatch”) was attached using the laminator CL50.

Next, a laser coloring layer was printed over the PET substrate in a part of the area of the end of the hollow patch. As a material for forming the laser coloring layer, Elbima (registered trademark of Toyo Ink Co., Ltd.) Z117 (manufactured by Toyo Ink Co., Ltd.) was used.

Next, the feature amount of the facial photograph was two-dimensionally coded and drawn on the laser coloring layer using a laser marker. At the same time, dot-coded ID information was formed across the PET substrate by laser perforation using this laser marker in a partial region different from the position of the two-dimensional code at the end of the hollow patch.

Through the above steps, an ID card having a face photograph and ID information on a PET base material and having a holopatch attached thereon was produced as illustrated in FIG. An ID card formed with a two-dimensional code and a dot code was produced across a part of the end portion of the hollow patch and a PET base material adjacent to the area.

When the holopatch was peeled off from the ID card manufactured in this way, a part of the two-dimensional code and the dot code remained in the holopatch. Therefore, it is difficult to illegally use this holopatch by attaching it to other articles.

<Example 2>
First, a face photograph and ID information were printed on a PET substrate using a card printer CP500 (manufactured by Toppan Printing Co., Ltd.).
Next, a security hologram (hereinafter referred to as a “holopatch”) was attached using the laminator CL50.

This holopatch was used in which a region in which a vapor-deposited thin film of aluminum was previously formed in a part of the region (also referred to as an aluminum vapor-deposited region) was used. As a forming method, a mask vapor deposition method using a vapor deposition mask was used.

Next, ID information was bar coded and laser-drawn on the aluminum vapor deposition region. The aluminum thin film irradiated with the laser light was removed and demetallized (also referred to as dimeta). At the same time, the PET substrate was also drawn (see FIG. 4A). As a result, the bar-coded ID information 18, which carries the ID information, was formed in the aluminum vapor deposition region 19 formed by the dimeta processing, across the hollow patch 16 and the PET base material 17.

When the holopatch 16 is peeled from the PET base material 17 of the ID card thus manufactured, the holopatch as shown in FIG. 4B is obtained. In this hollow patch, a demetalized bar code 20 is formed in an aluminum vapor deposition region 19 (see FIG. 4A) formed by dimeta processing.

Therefore, the thus obtained horopatch is attached to a separately prepared PET base material 7 on a card having the ID information 17 and the face photograph 15 formed on the base material 7, and the demetaized barcode 20 is formed. When another barcode 21 is newly formed, moire occurs in the barcode. From that, it turns out that this card is forged.

<Example 3>
As illustrated in FIG. 5, a face photograph 15 and ID information 17 were first printed on a passport page made of paper 22 using an inkjet printer.

Next, the holopatch 16 having the aluminum vapor deposition region 19 formed by dimeta processing was laminated on the passport page.

Next, a face photograph was formed across the aluminum vapor deposition region 19 and the paper 22 adjacent thereto. As the face photograph, the face photograph 15 was reduced and used. The photograph of the face was formed by irradiation with laser light. In the aluminum vapor deposition region 19, the aluminum thin film was burnt off by laser light. Regarding the portion of the paper 22, a face photograph was formed by making holes in the paper 22 by irradiation with laser light.

The face photograph of the passport thus produced is formed across the aluminum vapor deposition region 19 at the end of the hollow patch 16 and the paper 22 adjacent thereto. Therefore, when the holopatch 16 is peeled off, a partially missing face photograph remains on the holopatch 16. Therefore, it is difficult to illegally use the holopatch 16.
