Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal authentication medium used for certifying an individual's qualification and status, such as a driver's license and an employee's card, and a device for manufacturing the same.

[0002]

[Conventional branch surgery] In recent years, white driving car licenses and employee IDs, etc.
ID cards that use a dye thermal diffusion recording device to record a face photograph on ID cards that require confirmation of the qualification owner, and that record personal character information such as name, address, and date of birth by heat fusion transfer are practically used. ing. It is necessary to prevent unauthorized use of these cards, and there is a demand for providing an ID card that is difficult to forge and that can be easily authenticated. A well-known technique that can respond to these demands is to add a hologram seal to the inside of a card used in cash cards and the like.
In the D card, authenticity determination means other than the hologram seal is required due to design restrictions.

This is due to the inconvenience that the existence of the hologram seal is apparent at first glance, and it is extremely easy to forge if the hologram seal is obtained.

[0004]

SUMMARY OF THE INVENTION It is a first object of the present invention to provide a personal authentication medium having authenticity determination means which is not easy to visually recognize and is difficult to forge.

It is a second object of the present invention to provide an apparatus for creating a personal authentication medium having authenticity determination means that is not easily visible and difficult to forge.

[0006]

According to the present invention, there is firstly provided a substrate having an image receiving layer on a surface thereof, and a first substrate provided on the image receiving layer.
The present invention provides a personal authentication medium including an information pattern including a colored layer having the above pattern and a transparent layer having the second pattern, and a protective layer covering at least the information pattern.

The present invention provides, secondly, means for forming an image receiving layer on the surface of a substrate, means for forming a colored layer having a first pattern on the image receiving layer, and means for forming a second pattern on the image receiving layer. A means for forming a transparent layer having: and a means for forming a protective layer on the colored layer and the transparent layer.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The personal authentication medium of the present invention is a medium having a base material, an image receiving layer provided on the base material, an information pattern, and a protective layer covering at least the information pattern. The information pattern includes at least a colored layer having a first pattern and a transparent layer having a second pattern.

Here, the colored layer is a layer which can be easily visually recognized such as a face photograph or a character information pattern recorded by using a dye thermal diffusion recording device or the like.

[0010] The transparent layer is transparent and colorless or slightly colored. The transparent layer can be visually recognized because the refractive index of the transparent layer is different from that of the protective layer formed thereon.

According to the personal authentication medium of the present invention, in a normal emmetropic state, only the colored layer is visually recognized and the transparent layer is not visually recognized, but the transparent layer can be visually recognized for the first time at a certain inclination angle. For this reason, the existence of the authenticity determination pattern is not easily recognized at first glance, as compared with the one having the authenticity determination mark. Further, even if the presence is known, it is extremely difficult to reproduce a pattern having such a delicate visibility at a similar visibility level and forge. Since this transparent layer can easily record different patterns / information for each individual, a high anti-counterfeiting effect can be expected.

The transparent layer is composed of fine particles or a resin having a refractive index different from that of the protective layer.

Examples of such fine particles include inorganic particles such as silica particles, glass particles, titanium oxide, calcium carbonate, and alumina particles, polymethyl methacrylate (PMMA), acryl, styrene, nylon, epoxy, polycarbonate, and fluorine-based particles. Colorless and transparent particles selected from resin particles such as resin particles, or finely colored particles such as polymethyl methacrylate (PMMA), polystyrene, nylon, and polyacrylate can be used.

As the resin, polyester, acrylic, styrene, nylon, epoxy, polyvinyl alcohol, polyvinyl butyral, urethane, acrylonitrile butadiene styrene, polyacetal, acrylonitrile butadiene rubber, styrene butadiene rubber and the like can be used.

The pattern of the colored layer can be formed by thermal transfer of a sublimable dye-containing ribbon, thermal transfer of a pigment-dispersed hot-melt ribbon, pigment-dispersed inkjet, or electrophotographic recording. In the case where the sublimable dye is thermally transferred, there is a possibility of fading of the sublimable dye.
It is desirable to form an ultraviolet shielding layer that does not easily dissolve in the ultraviolet curable resin liquid.

The transparent layer can be formed into a desired pattern by preparing a transparent layer pattern forming ribbon containing the above resin or fine particles and thermally transferring the ribbon. Further, an ink containing such a resin or fine particles can be prepared and printed by, for example, an inkjet method. Further, a sponge or the like may be impregnated with such an ink to provide a pattern.

The protective layer may be formed, for example, by applying and curing an acrylic or epoxy ultraviolet curable resin, thermally transferring a transferable transparent film such as polyester or acrylic, or laminating a transparent film such as polyester film, nylon or acrylic. , Can be easily formed.

An apparatus for manufacturing a personal authentication medium is means for forming a colored layer having a first pattern on an image receiving layer provided on the surface of a base material, and forming a transparent layer having a second pattern on the image receiving layer. And a means for forming a protective layer on the colored layer and the transparent layer.

As a means for forming the colored layer, a thermal transfer device, an ink jet device, an electrophotographic recording device, or the like can be used.

As a means for forming the transparent layer, a thermal transfer device, an ink jet device, or a device for impregnating a sponge or the like with an ink containing the above-mentioned resin or fine particles to give a pattern can be used.

When a sublimable dye is thermally transferred,
Since there is a possibility that the sublimable dye may be discolored, it is desirable to provide a means for forming an ultraviolet shielding layer at the subsequent stage of the thermal transfer device for forming the sublimable dye pattern. As such a means, for example, a thermal transfer type resin layer containing an ultraviolet absorbent can be used.

The personal authentication medium of the present invention can be used as an authenticity determination means for booklets or notebooks, such as an ID card, a bankbook, a pension book, and the like, for which it is necessary to confirm the match between the owner and the carrier.
