Description

The present invention relates to a copy prevention information recording sheet and a copy prevention information recording sheet that make it impossible to copy predetermined individual information to be recorded.

In recent years, various cards such as IC cards have become widespread, and predetermined individual information to be prevented from counterfeiting is also recorded on these cards. It is desired that such a card ensures robustness without increasing the cambium, particularly with respect to the individual information portion, and enables recording confirmation at the time of recording the individual information.

Conventionally, as an information recording medium for copy protection, for example, an infrared absorption code pattern layer on which information of a copy prevention target is recorded is formed by printing with infrared absorption ink, and printing ink is printed on the infrared absorption code pattern layer. A technique for forming a printing layer to be printed using the printing layer, and an infrared absorbing code pattern layer for forming a printing layer to be printed using printing ink on a substrate and recording information on a copy prevention target on the printing layer. Is known by printing with an infrared absorbing ink (Patent Document 1).

Further, as another technique, a laser recording layer is provided on the surface of a sheet-like base material, and a protective layer in which a concealing layer is printed on the back surface is provided on a predetermined recording area of the laser recording layer. An information recording medium for recording concealed information by irradiating a predetermined recording area with a laser beam via a protective layer and a concealing layer is also known (Patent Document 2).

However, in the technique described in Patent Document 1, since the infrared absorbing cord pattern layer and the printing layer are formed by printing with printing ink, they may be scraped off by friction or intentionally scraped off. There is a problem that it is easy and lacks wear resistance, and forming a protective layer to prevent this causes an increase in the number of formed layers. Further, in the technique described in Patent Document 2, since laser recording is performed on the laser recording layer via a concealing layer, it is necessary to separately confirm whether or not the recording is performed with a dedicated reader. There is a problem that it is inefficient.

Therefore, the present invention has been made in view of the above problems, and is a copy prevention information recording sheet and a copy prevention information record that ensure robustness without increasing the number of cambium layers and enable the recording of copy protection target information to be visually confirmed. The purpose is to provide a sheet.

In order to solve the above problems, in the invention of claim 1, a base material, a copy prevention layer formed of an infrared transmissive member in a region on the base material on which copy prevention target information is recorded, and at least the copy. It is configured to have a laser recording layer of a resin formed on the prevention layer and provided with a laser light absorber.

In the invention of claim 2, it is formed on at least the copy protection layer by the base material, the copy protection layer formed by the infrared ray transmitting member in a predetermined region on the base material, and the resin provided with the laser light absorber. The configuration includes a laser recording layer in which copy protection target information is recorded by laser light in a region on the copy protection layer.

According to the invention of claim 1, a copy prevention layer is formed by an infrared transmissive member in a region on a base material on which copy prevention target information is recorded, and at least a resin laser recording layer formed on the copy prevention layer. Therefore, by configuring the laser recording layer to include the laser light absorber, the copy protection layer is located inside the laser recording layer, and the recording of the copy prevention target information of the laser recording layer can be visually confirmed. Since the laser recording layer is made of resin and is robust, it is possible to prevent falsification due to abrasion or scraping even after recording the copy protection information.

According to the invention of claim 2, a copy protection layer is formed by an infrared transmitting member in a predetermined region on a base material, and at least a laser recording layer of a resin having a laser light absorber is formed on the copy protection layer. Therefore, by configuring the laser recording layer in which the copy protection target information is recorded by the laser beam in the region on the copy protection layer, the recording of the copy prevention target information of the laser recording layer is visually confirmed. In addition, since the laser recording layer is made of resin and is robust, robustness can be ensured without increasing the number of formed layers at least in the portion where the copy protection target information is formed, and the copy protection target information can be ensured. It is possible to prevent tampering due to abrasion or scraping.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration diagram of a copy prevention information recording sheet according to the present invention. In FIGS. 1A and 1B, the copy protection information recording sheet 11 has a copy protection layer 13 in an area on a base material 12 such as paper, a resin film, or a resin plate on which copy prevention target information is recorded. Is formed, and a resin laser recording layer 15 provided with a laser light absorber is formed on the base material 12 including the copy protection layer 13 via the sticking layer 14. Although not shown, the copy protection layer 13, the adhesive layer 14, and the laser recording layer 15 having the same configuration may be provided on the other surface (lower surface) side of the base material 12.

The copy protection layer 13 is formed by printing using, for example, a dye-based infrared transmissive ink, which has been conventionally known as an infrared transmissive member. The infrared transmissive ink exhibits high transmittance in the vicinity of the near infrared 850 nm wavelength or higher, and blocks visible light (400 to 750 nm region) and ultraviolet rays (190 to 400 nm region). Here, the information formed on the laser recording layer 15 is black, and an infrared transmissive ink of the same color is used.

The laser recording layer 15 is configured in a form in which a laser light absorber is contained in a preferably transparent resin through which the laser light passes. As the resin, thermoplastic resins such as polyethylene terephthalate (PET), polyethylene terephthalate glycol (PET-G), polycarbonate (PC), polyvinyl chloride (PVC) and the like are used. Further, the laser light absorbing material absorbs laser light and changes color to a predetermined color. For example, a phthalocyanine dye, a cyanine dye, a metal complex dye, or a diimmonium dye is used as a material that changes color to black. To. A dye other than black may be used as long as it has the same color as the copy protection layer 13. The thickness of the laser recording layer 15 is, for example, 50 μm to 100 μm.

For the adhesive layer 14 to which the base material 12 and the laser recording layer 15 are attached, an adhesive such as a hot melt or an ultraviolet curable adhesive can be used. Further, the bonding layer 14 may be a layer in which the base material 12 and the laser recording layer 15 are heat-sealed at, for example, 100 to 150 ° C. The laser recording layer 15 may be present on the copy protection layer 13 to realize the function of the present invention.

Here, FIG. 2 shows an explanatory diagram of the copy prevention target information record for the copy prevention information recording sheet of FIG. In FIG. 2A, the copy protection information to be recorded is used as a two-dimensional code, and the laser is applied to the region on the copy protection layer 13 of the copy protection information recording sheet 11 from the laser recording layer 15 side along the code pattern. The recording layer 15 is irradiated with the recording laser beam 21 in focus.

In the portion irradiated with the recording laser beam 21, the laser light absorbing member (for example, including a member that changes color to black) included in the laser recording layer 15 absorbs the laser beam and develops a black color. As a result, as shown in FIGS. 2 (B) and 2 (C), the copy prevention target information 31 as a two-dimensional code is formed on the laser recording layer 15 on the black copy protection layer 13, and the copy protection information recording sheet 11A It becomes. The copy prevention target information 31 allows the recording form to be visually confirmed even when the black copy prevention layer 13 is used as the background from the laser recording layer 15, and it is possible to visually confirm whether or not the information is recorded. is there.

On the other hand, even if an attempt is made to copy the copy prevention target information 31 recorded on the laser recording layer 15, the copy prevention target information 31 and the copy prevention layer 13 are of the same color system, so that the copy prevention target information 31 is copied. Is something that cannot be done. Although it is not particularly necessary to ensure robustness, a protective layer of an infrared transmitting member may be formed on the laser recording layer 15. The protective layer in this case may be formed before or after laser recording on the laser recording layer 15. This point is the same in FIG.

Therefore, FIG. 3 shows an explanatory diagram of reading the copy prevention target information from the copy prevention information recording sheet after the information is recorded in FIG. In FIG. 3, the copy prevention target information 31 of the recorded two-dimensional code is read by the code reader 41 using infrared rays on the copy prevention information recording sheet 11A.

That is, on the copy protection layer 13, the laser-recorded portion (blackened portion) absorbs the infrared rays output from the code reader 41, while the infrared rays pass through the copy protection layer 13 in the portion not laser-recorded. By reflecting the light on the base material 12 and receiving the light, the information is recognized and analyzed as the reading record information 31A of the two-dimensional code as a whole.

Next, FIG. 4 shows an explanatory diagram of a copy protection information recording card to which the copy protection information recording sheet of the present invention is applied. In FIGS. 4A and 4B, the copy protection information recording card 11B has a printing layer 51 for common information such as desired patterns and figures on one surface of the base material 12, and is formed on or based on the printing layer 51. A copy prevention layer 13 is formed on the material 12 with infrared transmissive ink.

Then, the laser recording layer 15 is attached on the base material 12 (printing layer 51) with the attachment layer 14 interposed therebetween. In the laser recording layer 15, copy protection target information 31 is formed in a region on the copy protection layer 13, and first individual information 52 is formed in other regions. Further, a film transfer layer 16 on which the second individual information (face photograph in the figure) 53 is formed is provided on the laser recording layer 15. Although not shown, the copy protection layer 13, the adhesive layer 14, the laser recording layer 15, and the film transfer layer 16 having the same configuration may be provided on the other surface (lower surface) side of the base material 12.

The copy prevention information recording card 11B as described above plays a role of forgery prevention without copying the copy prevention target information 31 in relation to the copy prevention layer 13 and the copy prevention target information 31. Further, in the relationship between the upper and lower two layers of the first individual information 52 and the second individual information 53, the copying is performed as information on the same surface, so that the authenticity can be easily determined visually. It can also play a role in anti-counterfeiting.

Therefore, FIGS. 5 and 6 show an explanatory diagram of the production of the copy protection information recording card of FIG. First, in FIG. 5A, the common information is printed on the base material 12 to form the print layer 51, and the copy prevention layer 13 is formed by printing on the region where the copy prevention target information 31 is formed. When the print layer 51 is formed on the entire surface of one surface of the base material 12, the copy protection layer 13 is printed on the print layer 51, while the copy protection layer 13 is placed on the base material 12. When the entire other region is used as the print layer 51, it can be performed in one printing step, and if the copy protection layer 13 and the print layer 51 have the same thickness, flattening is achieved and the laser in the subsequent step is achieved. It is suitable for forming the recording layer 15.

Subsequently, as shown in FIG. 5B, an adhesive such as hot melt is applied to the entire upper surface of the copy prevention layer 13 and the print layer 51 on one surface of the base material 12 to form the adhesive layer 14. Will be done. Then, as shown in FIG. 5C, the laser recording layer 15 is attached onto the attachment layer 14 to form a common copy prevention information recording sheet 11C.

As shown in FIG. 6A, for example, a film transfer layer 16 in which the second individual information 53 is color-printed by a ribbon method is prepared for the copy protection information recording sheet 11C, and the copy protection information recording sheet is provided. The film transfer layer 16 is attached onto 11C (the surface on which the copy protection layer 13 and the print layer 51 are formed) by heat fusion.

Subsequently, as shown in FIG. 6 (B), the region of the copy protection layer 13 of the laser recording layer 15 and other desired regions are sequentially irradiated with the recording laser beam 21 to obtain FIG. 6 (C). As shown, by forming the copy protection target information 31 on the copy protection layer 13 and forming the desired first individual information 52 in the other regions, the copy prevention information recording sheet 11C is used as a base for each individual copy prevention information recording sheet 11C. The copy protection information recording card 11B is produced.

The formation of the film transfer layer 16 (FIG. 6 (A)) and the information recording on the laser recording layer 15 (FIG. 6 (C)) may be performed in any order. That is, the information recording on the laser recording layer 15 may be performed via the film transfer layer 16 or may be performed directly on the laser recording layer 15.

On the other hand, when the second individual information 53 is formed, it is not limited to the film transfer layer 16, and may be formed directly on the laser recording layer 15 by a so-called ultra graphic (UG) or inkjet printing method.

As described above, the recording of the copy prevention target information 31 of the laser recording layer 15 can be visually confirmed, and since the laser recording layer 15 is made of resin and is robust, at least the copy prevention target information 31 is present. Robustness can be ensured without increasing the number of formed layers in the formed portion, and falsification due to abrasion or scraping of the copy prevention target information 31 can be prevented.

By the way, the copy protection information recording sheet 11A of FIG. 2 and the copy protection information card 11B of FIG. 4 are replaced with a magnetic card having a magnetic recording layer, a contact IC card provided with a contact IC module, an antenna and an IC module (IC). It can be applied to a non-contact type IC card equipped with a chip), a dual IC card capable of contact / non-contact communication, and the like. In this case, for example, when the IC module is mounted, the laser recording layer 15 is formed on the base material 12 to have a transmittance so that the IC module cannot be seen through, and the magnetic recording layer is also formed. Is mounted on the laser recording layer 15.

Further, after laser recording on the laser recording layer 15 (after confirmation of recording), a film transfer layer having a predetermined design formed by infrared transmissive ink is heat-sealed so that the copy prevention target information 31 cannot be visually recognized. It can also be done.

The copy protection information recording sheet and the copy protection information recording sheet of the present invention can be used in the industrial fields of manufacturing, selling, and using cards in which individual information for copy protection is recorded.
