Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a so-called overprint card concealed on a magnetic recording layer, and further relates to a magnetic card provided with a pattern layer on the concealment layer.
[0002]
[Prior art]
Conventionally, a magnetic card called a normal overprint card has been known in which a concealing layer is provided on a magnetic recording layer such as a magnetic stripe by screen printing or the like, and the design is improved so that the magnetic stripe cannot be seen. ,It's being used.
However, as shown in FIG. 2 (A), the overprint card in the prior art first has a thickness of about 0.1 mm on both sides of the center core material 1 having a thickness of about 0.4 to 5 μm such as vinyl chloride resin. An oversheet t, t made of a vinyl chloride resin or the like is laminated, and a magnetic recording layer 2 (generally a magnetic stripe) is provided at a predetermined position to constitute a card substrate. Next, the masking layer 3 made of printing ink or the like is applied to the thickness of about 1 to 10 μm on the magnetic recording layer or over the entire surface of the substrate by screen printing or the like, and a pattern layer is directly provided on the masking layer 3. Alternatively, as shown in the figure, a magnetic card can be obtained by providing a solid ink layer 7 for a pattern layer and providing a pattern layer 5 with a thin ink film thickness thereon. However, these have various limitations. For example, it was not possible to provide a white solid ink layer with a white ink or a light solid ink layer for improving the design of the pattern layer provided on the masking layer.
[0003]
The reason for this is that, as shown in FIG. 2A, first, the white solid ink layer 7 is set thin (ink film thickness, white ink concentration, etc.), and then the concealing layer 3 (for example, gold ink, The color of silver ink or the like cannot be concealed, and even if a picture layer is provided directly on the concealing layer, the card quality is deteriorated.
Further, when the thickness of the white solid ink layer 7 is set to be thick, the whiteness is improved. However, as shown in FIG. 2B, the magnetic output at that portion is remarkably lowered and becomes out of specification. Therefore, the conventional overprint card (magnetic card) is limited in design, and it is difficult to manufacture a card based on the required quality.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention has been made in view of the above problems, and it is possible to print an arbitrary picture layer by improving the setting of the concealment layer, and to provide a magnetic card having a stable magnetic output. Objective.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides:
The first hiding layer 3 and the second hiding layer 4 are provided on the card substrate 1 provided with the magnetic recording layer 2, and the first hiding layer partially exposed is not the same color as the hiding layer. A solid ink layer 7 is provided, a pattern layer 5 is provided on the solid ink layer , a window frame 9 is provided in a partial region of the second concealing layer 4, and a solid ink layer 7 that is not the same color as the concealing layer is provided in the window frame. which is a magnetic card, characterized in that provided.
[0006]

[0007]
Further, the window frame 9 of the second concealing layer 4 is provided above the magnetic recording layer 2.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the magnetic card 10 of the present invention, the concealing layer is composed of two layers of the first concealing layer 3 and the second concealing layer 4. In this window frame, a colored or white solid ink layer 7 different from the concealing layer is provided, and a pattern layer 5 such as a mark is provided on the window frame. A stable card can be provided.
[0009]
Embodiments of the present invention will be described in detail with reference to the drawings.
1A and 1B show an example of a magnetic card in an embodiment of the present invention. FIG. 1A is a cross-sectional explanatory view of the magnetic card, and FIG. 1B is an explanatory view showing an example of a magnetic output waveform of the card. .
[0010]
First, as shown in FIG. 1A, an oversheet t having a thickness of about 0.1 mm made of vinyl chloride resin or the like is formed on both surfaces of a center core 1 made of vinyl chloride resin or the like having a thickness of about 0.45 to 0.5 mm. , T is used as a card substrate.
A magnetic recording layer 2 is provided on the card base, and a magnetic stripe having a predetermined width is generally used for the magnetic recording layer. Further, the magnetic stripe can be appropriately selected from either a method of laminating one provided on the oversheet or a method of directly sticking to a card substrate on which the oversheet is laminated. The magnetic stripe can be provided on one side or both sides of the card substrate.
[0011]
Next, since the color of the magnetic recording layer 2 (magnetic stripe) on the card substrate is dark brown or black, the first concealing layer 3 is applied to a thickness of about 0.5 to 5 μm to conceal the magnetic recording layer. To do. If it is applied too thick, it affects the reproduction output of the magnetic recording layer, so it is preferable to select it within the aforementioned thickness range. This concealing layer can be freely designed including on the magnetic recording layer. Therefore, in order to make use of this hiding power, generally used is a method in which high-concentration colored ink or gold or silver ink is used, and screen printing or the like is used for printing.
[0012]
Furthermore, in the present invention, the second concealing layer 4 is provided on the first concealing layer 3 in a thickness of about 0.5 to 5 μm to improve the concealing power. This second hiding layer 4 is provided with a window frame 9 of an appropriate size in a partial region (a blank portion is formed in a part of the second hiding layer), and the bottom of the window frame 9 not printed is The first hiding layer is exposed. The window frame is provided at the position of the upper layer portion of the magnetic recording layer, and is preferably a region slightly wider than the width of the magnetic recording layer (magnetic stripe).
[0013]
However, although it is not limited, it is common to apply the ink of gold, silver or the like as described above to the first hiding layer with a colored ink having a concentration and to the second hiding layer.
[0014]
Next, a solid ink layer 7 is applied in the window frame 9 of the second concealing layer 4 using ink of a color different from that of the first and second concealing layers. That is, a solid ink layer is applied in the window frame from which the first hiding layer 3 is exposed. The solid ink layer is preferably a white solid ink in order to improve the design of the pattern layer, which will be described later. However, the solid ink layer is not limited to this, and it may be different from the color of the masking layer. Also, the thickness of the solid ink layer 7 is preferably about 1 to 5 μm, and this printing method can be selected as appropriate, such as screen printing or offset printing.
[0015]
Furthermore, the pattern layer 5 is provided on the solid ink layer 7 described above. As described above, the solid ink layer is preferably a white ink layer, and the pattern layer 5 provided on the surface can use a light colored ink or the like, so that excellent design can be obtained in terms of design. In addition, a thin picture layer can be obtained by offset printing or the like.
[0016]
Further, a protective layer 6 is provided on the entire surface including the pattern layer in order to suppress the wear of the pattern layer and the hiding layer to a minimum. As this protective layer 6, it is preferable to use a transparent curable resin.
[0017]
As shown in FIG. 1 (B), the magnetic reproduction output in the magnetic card obtained by the above configuration could be kept within the upper and lower limits of the standard even if a concealing layer, a solid ink layer, and a pattern layer were provided in an overlapping manner. .
[0018]
[Action]
The magnetic card of the present invention is provided with a first concealing layer and a second concealing layer. A window frame (printing is performed on a part of the second concealing layer (a part requiring a pattern such as a mark). By providing a non-overlapping part, it is possible to limit the film thickness without overlapping the hiding layer, and it is also possible to provide a solid ink layer with a color ink different from that of the hiding layer. It is possible to improve the design by the design of the card and to keep the reproduction output of this card within the standard.
[0019]
【The invention's effect】
Since this invention is the above structure, there exist the following effects.
That is, the thickness of the concealment layer on the magnetic recording layer (magnetic stripe) in the magnetic card can be made thinner than that of the conventional card, so that the magnetic output satisfies the standard and the white solid ink layer A pattern using any colored ink can be provided on the magnetic stripe.
Therefore, it is possible to produce a magnetic card that has been impossible in terms of design in the past, and to achieve various effects such as improvement in design.
