[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embossed hologram card having a stripe-shaped magnetic recording layer having an information processing function and an embossed hologram, which provides a visually three-dimensional effect.

[0002]

2. Description of the Related Art Conventionally, as a full-surface embossed hologram card, for example, it is used as a card mainly having a decorative property without having a magnetic recording layer as an information processing function, or is provided on a surface opposite to a full-surface embossed hologram forming layer. Cards having a stripe-shaped magnetic recording layer are already used for some credit cards and the like. Further, a hologram-containing magnetic recording layer transfer sheet in which only a stripe-shaped magnetic recording layer is integrated with a hologram is known from Japanese Utility Model Laid-Open No. 2-71874.

However, a magnetic recording layer having a stripe shape (width of 5 mm to 15 mm) is formed on a credit card or the like (hereinafter referred to as a card).
mm), the embossed hologram is transferred onto the entire surface of the card, and there is a high demand for the production of a full-surface embossed hologram card. A card that does not interfere with the reading function is required.

[0004]

However, when an embossed hologram forming layer is provided on a magnetic recording layer to write and read information, the magnetic head comes into direct contact with the embossed hologram forming layer. The embossed hologram forming layer is scratched by dozens of reciprocating motions by the magnetic head, and the lower magnetic recording layer is exposed by about 100 times to impair the visual three-dimensional appearance and beautiful appearance. It could not be used for credit cards and the like. Therefore, the present invention is to transfer the embossed hologram forming layer onto a card substrate provided with a stripe-shaped magnetic recording layer, form a transparent protective layer in synchronization with the position of the magnetic recording layer, and heat and press. And a durable full-surface embossed hologram card is provided.

[0005]

[Means for Solving the Problems] To solve the problems,
At least an opalescent hard vinyl chloride sheet and a transparent hard vinyl chloride film are laminated, a stripe-shaped magnetic recording layer is provided thereon, and an embossed hologram is formed over the entire surface of the heated and pressurized sheet-shaped card substrate. This is a full-surface embossed hologram card formed by transferring a forming layer, forming a transparent protective layer on the surface thereof in synchronism with the stripe-shaped magnetic recording layer, heating and applying pressure, and punching out a desired size.

The entire embossed hologram card of the present invention has a milky white rigid vinyl chloride sheet having a thickness of at least 0.45 mm to 0.55 mm and a thickness of 0.08 mm to 0.5 mm.
A transparent vinyl chloride film of about 12 mm is laminated, and a stripe-shaped magnetic recording layer (width of about 5 mm to 15 mm) is temporarily fixed thereon at a predetermined position, and heated and pressed to form a sheet-like card base material, The embossed hologram forming layer is transferred onto the entire surface from above. Next, a transparent protective layer (1 μm to 5 μm in thickness) made of a reaction-curable resin is formed on the embossed hologram forming layer so as to be slightly wider than the width of the magnetic recording layer by synchronizing (matching the printing register) with the stripe-shaped magnetic recording layer. After heating and pressurizing again with a press machine to smooth the surface, the desired card size (5
A blank embossed hologram card with a magnetic recording layer can be obtained by punching out a piece of 4 mm x 85 mm.

[0007]

According to the present invention, an embossed hologram forming layer is transferred onto the entire surface of a stripe-shaped magnetic recording layer, and is tuned from there onto a portion corresponding to the stripe-shaped magnetic recording layer. In the card having the protective layer formed thereon, since the protective layer is transparent, the decorativeness of the embossed hologram forming layer and the visual three-dimensional effect are not lost, and the thickness of the protective layer is suppressed to 4 μm to 5 μm or less, so that the magnetic head The function of writing and reading information is not affected at all, and the abrasion resistance of the surface by the magnetic head is greatly improved by the reaction curable resin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional view showing a laminated structure of an entire embossed hologram card according to an embodiment of the present invention. The manufacture of the entire embossed hologram card (10) of the present invention is 3
Using a milky white rigid vinyl chloride sheet (1) having a size of 80 mm × 480 mm as a center core material, a transparent rigid vinyl chloride film (2, 2) is laminated on the front and back and temporarily fixed to a predetermined position on a surface where the magnetic recording is performed in a stripe form. Layer (3) (width 5
(appropriately selected from standards of mm to 15 mm). Next, the laminated temporarily fixed sheets are heated and pressed by a multi-stage press machine (temperature: 110 ° C. to 160 ° C., pressure: 2 ° C.).
0kgf / cm ² ~80kgf / cm ² or so) to the one sheet-like card substrate. The embossed hologram-forming layer (4) is transferred by using a transfer paper provided with a roll-shaped embossed hologram-forming layer (4) on the surface of the card base material. Next, a transparent protective layer (5) having a thickness of about 1 μm to 5 μm is appropriately provided on the embossed hologram forming layer by gravure printing or screen printing. At this time, it is preferable that the transparent protective layer is provided so as to be slightly wider than the stripe width of the magnetic recording layer by synchronizing (registering the printing) with the stripe-shaped magnetic recording layer provided below the embossed hologram forming layer (FIG. 2). See).

As the transparent protective layer (5), an acrylic or urethane reaction-curable transparent resin ink containing a lubricant such as silicon or wax (for example, Toyo Ink Co., Ltd.)
UR560N, YL105UR, etc.) are most suitable. Next, in order to smooth the surface, it is again heated and pressed by a press machine (temperature: 110 ° C to 160 ° C,
After performing the pressure 20kgf / cm ² ~80kgf / cm ² or so), the desired card size (54 mm × 85 m
By embossing in m), an entire embossed hologram card having a magnetic recording layer was obtained. In this embodiment, a hard vinyl chloride resin is used as a card base material. However, the present invention can also be applied to a so-called prepaid card or the like having a polyethylene terephthalate resin sheet as a main base material.

The surface of the transparent protective layer (5) above the magnetic recording layer of the entire embossed hologram card was subjected to a reciprocating abrasion test with a durability tester equipped with a magnetic head. , The embossed hologram forming layer was damaged, and the lower magnetic recording layer was exposed about 100 times.
There were no abnormalities even after 00 times.

[0011]

[Effects of the Invention] The entire embossed hologram card of the present invention has a significantly enhanced durability by providing a transparent protective layer on the embossed hologram forming layer, and has no problem in writing and reading information. Is obtained, and since the embossed hologram is formed on the entire surface, a beautiful card which visually shows a three-dimensional effect can be obtained.
