Abstract

PROBLEM TO BE SOLVED: To provide a concealing data carrier capable of reducing the control load of the ink build-up amount of a scratch layer and having no necessity for using a special base material. SOLUTION: A transparent protective layer 13 is provided so as to cover the concealing data 12 formed on a base material and peelable camouflage data 14 are formed on the transparent protective layer 13 so as to be alternate with the concealing data 12 and a scratch layer 15 is formed so as to cover the camouflage data 14. Even if the concealing data 12 are seen through by light to become a visible state, the camouflage data also become visible in the same way as the concealing data 12 and, since both data are seen so as to mingle with each other, accurate data are not cleared. Therefore, the control load of the ink build-up amount of the scratch layer 15 can be reduced. The camouflage data 14 can be shaven off together with the scratch layer 15 when used and only the concealing data can be visually observed. Further, it is unnecessary to use a special base material in order to develop concealing effect and cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an international telephone card,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concealed information carrier used for an Internet connection card, a net small settlement card, a lottery ticket, and the like, and more particularly to a concealed information carrier having a configuration in which confidential information such as a personal identification number and a lottery number is hidden by a scratch layer.

[0002]

2. Description of the Related Art Conventionally, as this kind of concealed information carrier, concealed information is printed on a base material, an OP varnish for protecting the concealed information is applied thereon, and silk screen printing is further performed thereon. The one provided with a scratch layer which can be peeled off is generally used.

[0003]

In the concealment information carrier described above, in order to prevent the concealment information from being seen through, the peelable scratch layer is formed by applying ink to a thickness of about 5 to 6 μm. desirable. However, there is a situation in which it is actually difficult to manage the ink volume. Therefore, in order to prevent the hidden information from being visible through the back surface with a strong light source, a dark color pattern is printed on the back surface,
Alternatively, there is a type in which a dark base is printed under the concealment information, and a type in which a pattern (forgery-inhibited pattern) is printed on the base. In some cases, a special base material such as paper sandwiching a metal reflective layer is used in order to obtain a hiding effect.

However, in a type in which a picture is formed on the back side in order to prevent the picture from being visible through the back side,
Since a dark color is used for the picture, there is a problem that the design is restricted, and there is also a problem that the number of steps for printing the back side increases. In addition, there is a problem that a type in which a dark background or a tint block is printed under the concealment information has a dark color as a whole. Further, the type using a special base material has a problem that the cost is high.

The present invention is intended to solve these problems, and an object of the present invention is to reduce the burden of managing the amount of ink in the scratch layer and to obscure the use of a special substrate. An object of the present invention is to provide an information carrier.

[0006]

Means for Solving the Problems In order to achieve the above object, the concealed information carrier of the present invention has a transparent protective layer covering the concealed information formed on the base material, It is characterized in that fake information that can be peeled off is formed alternately with concealment information, and a scratch layer is formed so as to cover the fake information.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view schematically showing a concealed information carrier according to the present invention. 2 (A) and 2 (B) are plan views of the concealed information carrier viewed from the front side and the back side, respectively, and FIG. 2 (B) shows a state where the concealed information carrier is exposed to light and seen through from the back side.

[0009] As shown in FIG.
Has a concealed information 12 formed on a base material 11 and a transparent protective layer 13 provided over the concealed information 12.
3 is configured such that peelable disguise information 14 is alternately formed with the concealment information 12 and a scratch layer 15 is formed so as to cover the disguise information 14. In FIG. 2B, numbers 1, 2, 3, and 4 are concealment information 12, and numbers 5, 6, 7, 8, and 9 are disguise information 14.

The material of the substrate 11 is not particularly limited, and general-purpose card paper or plastic sheet is used. Then, the concealment information 12 is formed on the base material 11 by printing or printing. In this case, various types of concealment information 12 are used depending on the application. In addition to the numbers as shown, for example, arbitrary characters, symbols, various patterns, and the like are included.

The transparent protective layer 13 is preferably formed by applying an OP varnish to the substrate 11 from above the concealment information 12 from the viewpoint of cost. Of course, it may be formed by other methods such as pasting with vinyl.

The camouflage information 14 is formed by silk-screen printing using ink of the same color as the concealment information 12, or
It is formed by silk screen printing using an ink of a color or a color having a different density from that of the scratch layer 15. Alternatively, printing may be performed by a printer or the like as long as it can be formed to be peelable. Then, the scratch layer 15 is formed by silk screen printing so as to cover the camouflage information 14.

In the concealment information carrier 10, when viewed from the front side, as shown in FIG. 2A, the scratch layer 15 is exposed on the surface, and under the concealment information 12, both the concealment information 12 and the disguise information 14 are hidden. State. Then, the back side of the concealment information carrier 10 is covered with the concealment information 1 by light as shown in FIG.
Even if the situation 2 becomes visible and transparent, the camouflage information 14 becomes visible as well as the concealment information 12, and both pieces of information appear to intersect. Therefore, accurate information cannot be grasped.

When the scratch layer 15 of the concealment information carrier 10 is scraped off, the camouflage information 14 is also scraped off.
As shown in (A), the concealment information 12 becomes visible.
Of course, even if you can see the light through it and see through it from behind,
As shown in (B), only the concealment information 12 is visible.

In order to prevent the concealment information from being inferred by the arrangement of the concealment information and the disguise information, it is preferable that the concealment information and the disguise information are alternately arranged, for example, on a straight line or on a curve. FIGS. 4A and 4B are explanatory diagrams showing such an arrangement example, in which 〜 indicates concealment information.
Reference numeral 6 denotes disguise information.

[0016]

As described above, the concealed information carrier of the present invention is provided with a transparent protective layer so as to cover the concealed information formed on the base material, and is capable of peeling off the false information on the transparent protective layer. Is alternately formed with the concealment information, and furthermore, by adopting a configuration in which the scratch layer is formed so as to cover the disguise information, even if the concealment information can be seen through the light, the disguise information is also hidden. In the same way as the above, the information can be visually observed, and both pieces of information appear to intersect, so that accurate information cannot be found. Therefore, it is possible to reduce the management burden of the ink volume of the scratch layer. Moreover, when used, disguise information can be scraped off together with the scratch layer,
Only the concealment information can be viewed. In addition, there is no need to use a special base material for providing a hiding effect, and the cost can be reduced.
