[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems of the prior art. The object of the present invention is to provide an information recording card having a center base material provided with anti-counterfeit measures. The purpose of the present invention is to provide an information recording card which is not generalized in general and has a forgery prevention measure that is difficult to forge and copy.

[0005]

In order to achieve the above object in the present invention, first, in the invention of claim 1, there is provided an information recording card having a center base material provided with anti-counterfeit measures.
The anti-counterfeiting measure is characterized by using a transparent center base material and forming a line pattern of the same color or a similar color on substantially the entire front and back surfaces of the base material. It is a given information recording card.

According to the first aspect of the invention, a certain thickness (in the standard of the magnetic card, 0.6 including the protective layer and the like) is used.
(8 to 0.84 mm), a line pattern of the same shape or the same color is applied to almost the entire front and back surfaces of a transparent center base material, so that when viewed from one side,
When the lines on one side and the lines on the other side overlap, a normal line pattern is observed, and if you change the viewing angle to the direction perpendicular to this line, the line becomes thicker and A certain (blackened) line pattern is observed, and when the viewing angle is further changed, a completely dense (blackened) solid pattern is observed, which is not technically generalized and is counterfeited. It is possible to make an information recording card that is difficult to duplicate.

Further, in the invention of claim 2, the line width of the parallel line pattern is in the range of 0.3 to 1.0 mm, and the interval thereof is the same as the line width. The information recording card is provided with the anti-counterfeiting measure.

According to the second aspect of the invention, the line width of the parallel line pattern is set to be the same as the line width in the range of 0.3 to 1.0 mm. , If the lines on one side and the lines on the other side just overlap, a line pattern with a width and a space of 1: 1 is observed,
When the viewing angle is changed to the direction perpendicular to this line, the line becomes thicker, and when the viewing angle is further changed, a completely dense (darkened) solid pattern is observed. If the line width of this parallel line pattern and its interval are less than 0.3 mm, it is technically difficult to reproduce the position accuracy (parallelism, etc.) and line width of the parallel line pattern on the front and back surfaces by printing. In addition, since there is a limit to the ability of visually degrading parallel lines, the density change of the line patterns due to the angle change cannot be read, and conversely, the line width of the line patterns and the interval between them are 1.0 m.
If the angle exceeds m, the viewing angle is changed to the direction perpendicular to this line, but if the card is not tilted considerably, the line density will not change, which is not preferable.

According to the third aspect of the invention, a solid printing layer having a background color that makes the line pattern stand out is provided on the entire upper surface of one of the line patterns on the front and back surfaces. An information recording card provided with the forgery prevention measure according to claim 1 or 2.

According to the third aspect of the present invention, a solid printing layer having a background color that makes the line pattern stand out is provided on the entire upper surface of any one of the line patterns on the front and back surfaces. When viewed from the side where the printing layer is not applied, the density change of this line pattern due to the change of the line pattern and the viewing angle is more visible, and the information recording is provided with anti-counterfeit measures that make it easy to determine the authenticity. It can be a card.

Further, in the invention of claim 4, the design pattern is applied to the entire surface or a part of the solid printing layer, or a part of the line pattern on which the solid printing layer is not applied. An information recording card provided with the anti-counterfeit measure according to claim 1, 2 or 3.

According to the fourth aspect of the present invention, the information recording is performed by applying the design pattern including the kind of the information recording card on the solid printing layer or on the line pattern not provided with the solid printing layer. It is possible to provide an information recording card on which information such as the type of the card is transmitted, or forgery prevention measures for improving the design effect with the line pattern as a background are applied.

Furthermore, in the invention of claim 5, a transparent protective layer is provided on the outermost layers on the front and back of the center base material, and the forgery prevention measure according to claim 1, 2, 3 or 4. This is an information recording card provided with.

According to the fifth aspect of the present invention, by providing a transparent protective layer on the outermost layers on the front and back of the center base material, various characteristics as an information recording card, for example, a credit card or a cash card, for which a forgery prevention measure is applied. It is possible to use an information recording card that has been subjected to a forgery prevention measure that can withstand.

According to the Printing Encyclopedia (edited by the Printing Society of Japan), the above-mentioned "solid" is a portion which is completely covered with printing ink without any difference in shade or white portion on the printing surface. In the halftone dot printed matter, the halftone dot area ratio is 100%.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The information recording card provided with the anti-counterfeiting measure of the present invention,
For example, FIG. 2 is a plan view of FIG. 1 and its BB cross-sectional view.
As shown in the side cross-sectional view of FIG. 1, an information recording card (1) having a center base material (10) provided with anti-counterfeit measures, wherein a transparent center base material (10) is used as the anti-counterfeit measure. A parallel line pattern (12) of the same color or similar color is applied in parallel to the longitudinal direction of the card in the same pattern in substantially the entire area of the front and back surfaces (excluding the magnetic stripe (14) portion and its upper edge). This is an information recording card (1).

Further, in the present invention, as shown in the enlarged schematic view of FIG. 3, the line width (12) of the parallel line pattern (12) is
w) is in the range of 0.3 to 1.0 mm, and the interval (12
s) is the information recording card (1) on which the forgery prevention measure having the same line width (12 W) is applied.

By applying the forgery prevention measure by the line pattern (12) as described above, the transparent center base material (10) has a thickness (D) as shown in FIG. When viewed from the (front) side, when the line pattern (12) on the front surface and the line pattern (12) on the back surface of the transparent center base material (10) exactly overlap each other, it is shown in an enlarged schematic view of FIG. As shown, the line width (12w) and the interval (12s) look the same, but as shown in the enlarged schematic view of FIG. 4, the viewing direction is the direction (P) perpendicular to the line pattern (12). If you change it, the line pattern (1
2) is shifted and half of them appear to overlap, resulting in a thick line pattern (12 wa) and a narrow interval (12 sa),
It looks like a blackish color overall.

Further, by changing the angle of the viewing direction to the direction (P) perpendicular to the line pattern (12) (the card may be tilted at right angles to the longitudinal direction), as shown in FIG. The line pattern (12) looks completely displaced, and as a result, it appears as a solid pattern on the entire surface.

By changing the angle of the viewing direction as described above,
Alternatively, in order to allow the line patterns (12) on the front and back sides to be expressed as a density change by tilting the card, the line width (12w) is 0.3 to 10 as shown in FIG.
In the range of 1.0 mm, preferably about 0.5 mm, the interval (12 s) is the same as the line width (12 w),
If this line width (12w) is less than 0.3 mm, it is too fine and it is unreasonably wasted due to the problem of the technology for creating the line and the visual disassembly ability, and the line width (12w) is 1.0 mm.
If it exceeds the range, it is too thick, and if the card is not tilted considerably, there is no change in the density, which is not preferable.

Further, the parallel line patterns (12) on the front and back surfaces have the same pattern, and the colors thereof are the same color or similar colors, but the density is not particularly limited within this range. A relatively contrasting color such as black, gray or brown is preferred.

Further, in the present invention, as shown in the side cross section of FIG. 6, for example, the front and back lines are formed on the entire surface of the line pattern (12) provided on the back surface of the transparent center substrate (10). Information recording card (1) provided with a solid printing layer (20) having a background color that complements the pattern (12)
It is what

As described above, the solid printing layer (2) having a background color that complements the line pattern (12) on the front and back surfaces.
By providing 0), the line pattern (12) on the front and back sides can be seen conspicuously when viewed from the front side, and the change in the density due to shifting the angle of the viewing direction is also more noticeably visible, and therefore true / false judgment is also performed. The information recording card (1) can be provided with an easy forgery prevention measure.

As described above, since the line pattern (12) is preferably black, gray or brown,
The color of the solid printing layer (20) as a background color that complements the color of the line pattern (12) is preferably a color mainly composed of a relatively bright yellow color including white. However,
In addition to the role as the background color, the solid printing layer (20) also has a role of detecting the insertion (presence / absence) of the card by this machine with an optical sensor when the magnetic recording information of this card is mechanically read. Therefore, it is desirable that the solid printing layer (20) has a light-shielding property. For example, it is more preferable to use silver ink in which aluminum powder is dispersed in the white ink. Further, a bright yellow pigment may be dispersed in these to form a background color having a design effect.

The solid printing layer (20) is formed by
Although not shown in particular, it may be applied to the entire upper surface of the line pattern (12), but the authenticity determination at this time is performed from the back surface of the card.

Further, in the present invention, as shown in the plan view of FIG. 7 and the side sectional view of FIG. 8 showing the BB section, a line pattern is formed on the front and back surfaces of the transparent center base material (10), for example. (12) is applied, and the solid printing layer (20) is applied on the entire surface of the backside line pattern (12).
The information recording card (1) is provided with a design pattern layer (30) on a part of the line pattern (12) on which the surface (0) is not applied and which has been subjected to anti-counterfeit measures.

The design pattern layer (30) is for enhancing the design of this card including the card name and the like.
Generally, it is provided on the surface as shown in Fig. 1, and it is also provided on a part of the line pattern (12).
The true / false judgment of the card is made from above in the line pattern (12) without a line.

Further, depending on the hue and ink thickness of the design pattern layer (30), the line pattern (1
2) can be seen through, which may impair the design effect, so this design pattern layer (3
It is necessary to consider not to provide the line pattern (12) only on the lower part of (0).

As the design pattern layer (30), as shown in the side sectional view of FIG. 9, for example, a transparent center substrate (1
A line pattern (12) is applied to the front and back surfaces of (0), and a solid printing layer (20) is formed on the entire surface of the line pattern (12) on the surface.
It is also possible to provide an information recording card (1) on which a design pattern layer (30) is provided on a part of the solid printing layer (20) and anti-counterfeit measures are applied. Although not shown, the design pattern layer (30) may be provided on the entire surface of the solid printing layer (20).

In the information recording card (1) having the design pattern layer (30) provided on the solid printing layer (20) and having the anti-counterfeiting measure as described above, the authenticity determination is performed from the back side. The change in the line pattern (12) may be observed.

Furthermore, in the present invention, as shown in the side sectional view of FIG. 10, a line pattern (12) is provided on the front and back surfaces of a transparent center base material (10), and the line pattern (12) on the back surface is provided. ) Information in which a solid printing layer (20) is provided on the entire upper surface, a design pattern layer (30) is provided on a part of the surface line pattern (12), and a transparent protective layer (50) is applied to the outermost layers on the front and back. As the recording card (1), for example, a magnetic stripe (1
4) Various resistance when used as a cash card or credit card, that is, abrasion resistance, stain resistance,
The information recording card (1) is provided with anti-counterfeit measures that can withstand chemical resistance and the like.

The materials of the respective layers constituting the information recording card provided with the anti-counterfeiting measure of the present invention, the method of making the layers, and the like will be described below. First, as the transparent center base material (10),
The thickness of the transparent plastic is about 0.5 mm with the protective layer subtracted from the standard for magnetic cards (0.68 to 0.84 mm), such as vinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene ( P
E), polypropylene (PP), polystyrene (PS)
Alternatively, ABS sheets and the like are used, and vinyl chloride is often used because of its suitability for embossing, but due to environmental problems such as incineration, the above resins including amorphous PET have been devised and used. ing.

As the parallel line pattern (12), offset ink, gravure ink, screen ink or the like is used for each printing method, and the line width is 0.3 mm to
In the range of 1.0 mm, the interval is formed in the same manner as the line width.

Further, the solid printing layer (20) needs to be able to detect its presence or absence by an optical sensor of a reading machine, that is, it is necessary that it has a high light-shielding property, and it is bright based on silver ink containing aluminum powder. Colored offset inks, gravure inks, screen inks and the like may be used to form the respective printing methods, but screen inks are most preferable in view of their high light-shielding properties.
Furthermore, when the light-shielding property is given the highest priority, a metal thin film obtained by vapor deposition of aluminum or the like can be transferred to form the solid printing layer (20).

As the protective layer (50) provided on the outermost layers on the front and back sides of this card, a transparent vinyl chloride film having a thickness of 5 to 15 μm is generally heat laminated, but other acrylic or polyester (PET). Resins such as resins that have excellent heat resistance and fastness as the main components, and are blended with silicon or ethylene wax at a ratio of 1 to 5% by weight in consideration of slipperiness in machines and the like. It can also be formed by coating by a gravure method or the like.
