[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing an authentication identification card, and more particularly to a method of manufacturing an authentication identification card in which a hologram image effective for preventing forgery / alteration can be introduced in an arbitrary position and in an arbitrary shape.

[0002]

2. Description of the Related Art In recent years, by using a sublimation type thermal transfer that is excellent in gradation expression of identification information such as a facial photograph, an authentication identification card (hereinafter also referred to as an ID card) such as a driver's license, passport, student ID, membership card, etc. A manufacturing method in which bibliographic information such as an address and a name is formed by fusion-type thermal transfer has been put to practical use because a simple and high-quality card can be obtained.

Further, in order to prevent forgery / alteration of this type of card, there has been proposed a method of forming a hologram image by transferring it from a transfer sheet to an arbitrary constituent layer of the card, for example, Japanese Patent Laid-Open No. 4-338.
No. 593 is proposed.

[0004]

However, since the hologram image forming layer generally has a high hardness, a film piece called a burr is likely to remain on the outer periphery of the hologram image without being cut into a predetermined shape when formed by transfer. I understand.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a process for easily manufacturing an ID card having a hologram image of an arbitrary shape at an arbitrary position.

The present invention will be described in detail below.

In the present invention, the transparent protective layer having a hologram layer or formed on the second support so as to be peelable and transferable in a frame sequential manner with the hologram layer is constituted as a transfer foil for a protective layer, and is formed. By heating and pressing the surface of the image of information or bibliographic information, the substantially transparent resin protective layer is transferred to protect the image. This transfer foil has a width in the rotation axis direction of the heat roll used for transfer that is longer than the width of the card and may be a single layer, or may be a plurality of layers including an adhesive layer, a release layer, and / or an intermediate layer. It may be.

It is 3.0 μm, preferably 0.3 to 2.0 μm.

In the transfer foil for transparent protective layer of the present invention, the resin layer to be transferred has a cushioning property to enhance the adhesiveness with the information carrying layer at the time of transfer, and the adhesiveness between the adhesive layer and the peeling layer. It is preferable to provide an intermediate layer for the purpose of increasing the height. The film thickness is usually 0.2 to 3.0 μm, preferably 0.3.
Is about 2.0 μm. This intermediate layer preferably contains a thermoplastic resin, such as styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), styrene-ethylene / butylene-styrene (SEBS), styrene-ethylene / Examples thereof include propylene-styrene (SEPS) and styrene-ethylene / propylene (SEP) block copolymers. Other preferable resins include, for example, a composition constituting a hot melt adhesive (including an ethylene-vinyl chloride copolymer, a wax, a plasticizer, a tackifier, a filler, etc.) and polyvinyl acetate.

A transparent hologram can be formed by using a mixture of thermosetting resins and a thermoformable substance having a radically polymerizable unsaturated group, and a hologram image can be formed by superimposing it on identification information and bibliographic information.

In the present invention, as shown in FIGS. 1 and 2, in the heat roll 1 for thermally transferring the hologram image and the transparent protective layer, the length L in the rotation axis direction is larger than the width M of the card 2 in that direction. Of the protective layer transfer material (foil) 3 which is longer than the width M of the card and is longer than the width M of the card, and the card is overlaid and heated from above the protective layer transfer material 3.

This heat roll also has a circumferential length (πr
r: diameter, π: circle ratio) is in the circumferential direction (card transport direction)
Is longer than the length l of the card. That is, l <πr. As a result, the hologram image and / or the protective layer can be transferred onto the card surface before the heat roll makes one rotation, and the time required for thermal transfer can be shortened.

The heat roll may have a known structure, but it is preferable that the heat roll is made of rubber having a rubber hardness of 5 to 100 and a heat source (for example, a nichrome wire for heat transfer) is set in the hollow portion. Is preferably silicone rubber.

Has been. As described above, the shape of the heat roll used in the present invention does not necessarily have to be cylindrical as long as the length of the outer circumference is longer than the length of the card in the carrying direction, and the cross section is a kamaboko shape as shown in FIG. Alternatively, it may be a fan shape as shown in FIG. And preferably, the outer circumference of the heat roll has a length as close as possible to the length of the card, and the tip of the cutout portion D does not come into contact with the carrier table 14 as shown in FIG. 6 during standby when the card does not pass through the heat roll portion. The heat roll 1
It is possible to prevent the outer periphery of the heat roll 1 from coming into contact with the carrier 14 via the protective layer transfer material 3 by rotating the. As a result, the transparent protective layer is not transferred to the carrier and the heat of the heat roll is not lost to the carrier.

On the other hand, a normal ID card is JIS X 63.
As represented by 11 (dimensions of a prepaid card), the corners are rounded (the corners or corners are rounded) to provide safety. Thereby, when peeling the second support from the hologram layer and / or the transparent protective layer in the present invention, burrs are generated in the R portion at the rear end, and when a post-process for removing burrs is required, as a peeling plate, It is preferable that the length of the straight line portion that is in close contact with the card is substantially equal to the length of the non-R processed portion of the card, and both ends thereof are substantially cut so as not to contact the protective layer transfer material. This makes it possible to prevent the occurrence of burrs. The peeling angle is 45
It is preferable that the degree is less than or equal to the degree because the cutting of the hologram layer can be effectively performed.
