Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an information card suitable for use in prepaid mobile phones, international calls, scratch cards and the like.

[0002]

2. Description of the Related Art In a conventional prepaid card such as a magnetic card, that is, a prepaid card, fraud caused by forgery, alteration, and circuit breakage of a public telephone has become a problem. As a measure against this, instead of installing a balance management system for prepaid cards in public telephones, etc., we have introduced a system that allows the telephone company to centrally manage information such as the remaining count. Recently, prepaid mobile phones and international It is often used for telephones.

As such a card, a scratch card is used. With this scratch card,
It is possible to make a call by paying the fee first and then entering the unique number hidden in the hidden layer of the card into the telephone. Moreover, since the call charge is prepaid, it can be used for preventing overuse and as a gift, and the use of such cards has been rapidly increasing recently.

FIG. 5 is an explanatory view of an information card having a concealing layer formed by silk-printing of a prepaid card used in a conventional prepaid mobile phone, an international call, etc., and FIG. 5 (a) is a plan view and FIG. 5 (b) is a sectional view.

As described above, when the masking layer 10 is formed by silk printing, since a solvent is used for the masking layer ink, the intermediate protective layer 9 is provided to protect the print information, and further the print information is important. Depending on the card, a tint block layer 11 is provided on the concealing layer 10 and a protective layer 12 is further provided on the concealing layer 10 so that the print information 6 cannot be seen through. As described above, many steps are required in manufacturing.

FIG. 6 is an explanatory view of another conventional information card. The information card shown in FIG. 6 has the metal layer 1 on the base material 4.
Some of them are provided in the form of sanding to prevent light transmission, and FIG. 6 (a) is a plan view and FIG. 6 (b) is a sectional view.
As described above, there is a base material in which light is blocked by the base material 4 through the metal layer 13 to prevent light transmission so that it cannot be read before the hiding layer 10 is destroyed. However, the base material curls and the cost is high. There was a problem.

A foil-pressing type concealing layer has been developed in addition to silk printing, and FIG. 7 is an explanatory view of a conventional foil-pressing type information card. FIG. 7A is a plan view,
FIG.7 (b) is sectional drawing. As described above, the foil stamping method is very costly to deal with by printing, because the ink receiving layer 14 is provided, the printing is performed by an inkjet printer, and the intermediate protective layer 9 for protecting the printing is required. It was a structure.

[0008]

However, conventional scratch cards have been used by concealing simple information such as game cards and omikuji cards, but they are concealed in such telephones. At present, the importance of the content is increasing and it is becoming confidential information.
From this point of view, it is very serious in terms of security that the characters can be seen through the concealing layer and that the unevenness is seen through because the character information is printed by the ink ribbon or the like.

Therefore, as a means of preventing characters from being seen through when manufacturing a card, a tint block is printed on the concealing layer, the density of print information is reduced, printing is performed by an inkjet method, and ink is printed. By removing the unevenness like an ink ribbon by providing a possible ink receiving layer, applying black paint to the substrate itself, providing a metal layer between the layers of the substrate, using thermosensitive coloring instead of the ink ribbon, etc. There are many ingenuities.

As described above, many steps and additional treatments are required to improve security, leading to an increase in manufacturing cost. Therefore, recently, as a method that can be manufactured at low cost, a manufacturing method using a foil for the hiding layer has been established instead of providing the hiding layer by silk printing. However, in this case as well,
There are many problems such as legibility of print data due to unevenness due to thin foil, legibility due to local irradiation of light from the back side,
As a result, the above-mentioned processing is performed in order to solve it, and the current situation is that the cost has been increased.

In particular, these foil pressing methods are applicable to overlapping metal foils as in JP-A-2000-25374, but printing is performed by an ink jet printer in order to avoid unevenness of print data due to thin foils. It composes the data. However, in this case, it is necessary to provide an ink receiving layer on the base material so that the ink can permeate the ink, and a multi-structure is inevitable, such as providing a protective layer for protecting data even after printing.

Further, when the ink receiving layer and the ink jet system are not required, that is, when the ink ribbon is directly printed on the substrate, the unevenness of the ink ribbon can be confirmed from the upper part of the hiding layer, and the hiding layer is destroyed. Before doing so, there was a problem that information was leaked.

Therefore, the object of the present invention is to pay attention to the above-mentioned problems, and to form the hiding layer only by foil stamping without any printing layers for ensuring the hiding property. An object of the present invention is to provide an information card that solves the problems, has a low manufacturing cost, has a hiding layer that is decorative, and has a hiding layer that has a very high hiding property.

[0014]

The present invention provides an information card having information to be concealed, wherein the information card has one or more concealment layers on a base material, and at least one of the concealment layers is provided. It is an information card with irregularities.

The present invention is also an information card in which at least one layer of the hiding layer is a metal foil.

The present invention is also an information card in which at least one layer of the above-mentioned hiding layer is a pigment foil.

The present invention is also an information card in which at least one layer of the above-mentioned hiding layer is a dye foil.

The present invention is also an information card in which at least one layer of the above-mentioned concealing layer is a hologram foil.

Further, the present invention is the above information card, wherein when at least two concealing layers are laminated, the concealing layer is a combination of metal foil, pigment foil, dye foil and hologram foil.

Conventionally, a masking layer capable of scratching is provided by silk printing, and in order to maintain the concealing property of the print data, it is very costly in processing by reinforcing the printing, adding a tint block or the like. There were problems such as the prevention of legibility of characters due to unevenness and legibility of print data by forcing light, but by using a scratch foil instead of silk printing, by using a concealable foil itself It can be used at low cost and with high concealment.

That is, according to the present invention, in an information card having information to be concealed, the information card has one or more concealing layers on a substrate, and at least one of the concealing layers is provided with irregularities. It is an information card characterized by that.

[0022]

[Embodiment] Regarding the information card according to the embodiment of the present invention,
This will be described below.

(Embodiment 1) FIG. 1 is an explanatory view of an information card according to Embodiment 1 of the present invention, FIG. 1 (a) is a plan view, and FIG. 1 (b) is a sectional view. .

First, by forming the concealing layer by foil stamping, there is no formation of a multiple structure by silk printing or offset printing, and since a solvent is not used for the concealing layer, it is necessary to consider the solvent resistance of the printing information. Since there is no intermediate protective layer, there is no need to print a tint block, and it can be manufactured at low cost.

Here, as the base material 4 used, paper and plastic film can be used. In the case of paper, Kent paper, coated paper, wood free paper, etc. are mentioned. In the case of a plastic film, it is not particularly limited, but various films such as polyethylene terephthalate, polypropylene, polystyrene and polyvinyl chloride can be mentioned.

The printing information used here can be printed by a thermal transfer method such as an ink ribbon, a toner transfer method, an ink jet method or the like, but it has a printing layer such as an ink receiving layer. In addition, the printed part, which is provided under the concealing layer that is generally scraped off and is supposed to be scraped, must have good adhesion to the base material, and is also resistant to abrasion. A thermal transfer system using an object, that is, an ink ribbon or the like is preferable. The thickness is generally 1 to 10 μm, but it is preferable that the unevenness of the print information is difficult to recognize and the adhesion is strong, that is, 1 to 3 μm. The concealing layer 2 is easy to conceal, and the thickness is preferably 2 to 20 μm in consideration of the sharpness.

Further, the foil used here may have a scratch effect, that is, a weak adhesion to the base material, and an adhesive which is peeled off by shaving is applied, and the hiding property is further enhanced. If desired, it is also possible to use a black pigmented adhesive. The foil can be any foil such as pigment foil, metal foil, dye foil, hologram foil,
When it is desired to increase the hiding power, it is preferable to use a color capable of blocking light such as black. However, in the case where the structure is composed of only one layer as described above, the problem as shown in FIG. 2 may occur depending on the foil used.

(Embodiment 2) FIG. 2 is an explanatory diagram of an information card according to Embodiment 2 of the present invention. FIG. 2A is a plan view and FIG. 2B is a sectional view. In the information card according to the second embodiment, when the concealing layer is formed by only one layer, the foil is inevitably selected with emphasis on the concealing property, and the printed information 6 appears as unevenness depending on the foil used. By shining light from the side, the printed information can be easily seen through, and the structure tends to be centered on black.

(Third Embodiment) FIG. 3 is an explanatory diagram of an information card according to a third embodiment of the present invention. FIG. 3A is a plan view and FIG. 3B is a sectional view. In the information card according to Example 3, the concealing layer has a two-layer structure, and the first concealing layer 2 has a metal foil, a pigment foil, a dye foil, and a hologram foil to ensure the concealing property, and further the second concealing layer. It is possible to give various variations to 8, such as using colored metal foil, pigment foil, dye foil, and hologram foil.

As described above, the concealing property is remarkably improved by the multi-structure. As the foil used for the first layer, an adhesive having a scratch effect is required, and all colors of the foil can be used, but black is preferable in order to improve the hiding property. As the foil used for the second layer, generally, a scratch effect is not required, and any material that strongly adheres to the surface of the concealing layer of the first layer may be used, and pigment foil, dye system, metal vapor deposition foil, hologram foil, etc. are used. It is possible and any color and pattern can be used. By using such a combination, a hiding layer having a high hiding property and a very good decorative property can be constructed. The plate used for hot stamping can have a pattern utilizing various irregularities, and the plate used here is generally a zinc plate, a magnesium plate, a resin plate or the like.

As described above, by providing unevenness on the plate, unevenness can be imparted to the foil to be transferred, so that the unevenness of the print information under the concealing layers 2 and 8 of the foil becomes inconspicuous and very difficult to read. A hidden layer with high security can be constructed.

(Embodiment 4) FIG. 4 is an explanatory diagram of an information card according to Embodiment 4 of the present invention. FIG. 4A is a plan view and FIG. 4B is a sectional view. In the information card of the present invention, as shown in FIG. 4, since the unevenness 7 (company name, logo, pattern, etc.) of the foil unique to the card can be displayed in the unevenness without printing the tint block, the card itself can be differentiated. This makes it possible to easily construct a highly decorative information card.

[0033]

As described above, according to the present invention, the concealing layer is provided by the foil pressing method instead of the conventional silk printing.
It is possible to easily and inexpensively manufacture a scratch card, and to provide an information card having a very high hiding property and a good decorative property without using any printing layer related to the hiding layer.
