Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a magnetic card used as a credit card, a bank cash card, and various other identification cards.

[Technological forward leaning of the invention and its problems] Conventional magnetic cards have a core sheet made of an opaque synthetic resin such as polyvinyl chloride, and a transparent oversheet also made of a synthetic resin such as polyvinyl chloride. It has a magnetic layer for storing required information. This magnetic layer is usually provided on the oversheet, while patterns such as pictures are printed on the core sheet. Therefore, in conventional magnetic cards, the magnetic layer and the pattern are usually provided independently of each other. For this reason,
In conventional magnetic cards, the color of the magnetic layer is limited (usually brown) and because the magnetic layer is provided on an oversheet, the magnetic layer is inevitably visible from the outside and hides the pattern, making it difficult to design. There are significant limitations in improving the appearance in terms of appearance.

In order to solve these problems with conventional magnetic cards, a colored layer containing a pigment such as titanium white is formed on the magnetic layer to hide the color of the magnetic layer, and then a pattern layer is placed on top of it. A method has been proposed (Jibun Sho 54-73608).

However, in the above-mentioned conventional cards, since a non-coated pigment such as T + 02 is used as a colored layer that hides the magnetic layer, it is not always possible to obtain a satisfactory aesthetic improvement of the card. Furthermore, the concealing properties of the magnetic layer were also insufficient.

Furthermore, in conventional magnetic cards, when a visible information section is separately provided in the card, there are restrictions in obtaining an excellent design.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and has excellent concealment properties of the magnetic layer and aesthetic appearance, and in particular, gives an impression that the visible information section provided in the card stands out vividly. The purpose is to provide magnetic cards.

(R essential points of the invention) As a result of various attempts to improve the aesthetic appearance of magnetic cards, the present inventor has found that by laminating a colored layer containing metal powder on the magnetic layer, the card has a solid and luxurious appearance. It has been found that a magnetic card can be obtained which has excellent magnetic properties, hides the magnetic layer well, and has no adverse effect on magnetic properties due to the presence of such a colored layer.

Furthermore, by providing a visible information section on the lower layer side of the colored layer containing metal powder, and making each upper layer of this visible information section transparent, the visible information section can be vividly colored by the contrast with the colored layer. It has been discovered that a magnetic card with an excellent design that gives a standing impression can be obtained.

That is, the magnetic card according to the present invention has a visible information section provided on a part of the card cover material, and further includes an oversheet layer having a magnetic recording section, a colored layer containing metal powder, and a pattern layer. It is characterized in that the layers are laminated in this order, and each layer above the portion where the visible information section is provided is light-transmissive.

(Embodiments of the Invention) Hereinafter, the present invention will be described in detail based on the drawings and compared with a conventional example.

FIG. 2 is a sectional view showing the laminated structure of a conventional magnetic card. The magnetic card 1 consists of a pair of core sheets 1a and 1a2 made of opaque synthetic resin, such as vinyl chloride, and a transparent overcoat made of the same material on both sides. Sheet 1b, 1b
It is constructed by covering 2 with a laminate.

Further, a pattern portion or a visible information portion 2 is provided in advance with printing ink on the surfaces of the oversheets 1b and 1b2 that are in contact with the core sheets 1a1 and 1a2, respectively, and a magnetic layer 3 is provided on a part of the surface of the oversheet 1b1. It is provided.

On the other hand, FIGS. 1A and 1B show two typical examples of the laminated structure of the magnetic card of the present invention.

Referring to FIG. 1, the magnetic card 1 is made by laminating and covering a pair of core sheets 1a and 1a2 with oversheets 1b and 1b2 on both sides, and between the oversheets 1b and 182 forming the back surface. It is also similar to the conventional magnetic card that a 2° pattern 2 is provided in the printing ink as necessary.

In addition, the above-mentioned meat receiver is also the oversheet 1b.

is made of thermoplastic resin.

The core sheet and oversheet 1b2 are preferably made of thermoplastic resin, but may also be made of thermosetting resin, paper, or the like. In the present invention, the term "thermoplastic resin substrate" includes such a substrate in which only the surface layer is made of thermoplastic resin.

In the example of FIG. 1A, the oversheet 1 forming the surface
A magnetic field 13 is embedded in a part of b1, and a visible information section 4 is printed and formed on the oversheet 1b having this magnetic layer, and the oversheet 1b further covers this magnetic layer 3.
A colored layer 5 made of printing ink or the like, a pattern H6, and a protective layer 7 made of a transparent synthetic resin are sequentially provided on the photosensitive material 1 .

Each upper layer of the visible information section 4 is covered with a light-transmissive layer by being punched out or a non-printing section. Ho-V! ! Although 17 is not essential to the magnetic card of the present invention, it is preferable in order to prevent coloring 15 and pattern E6 from fading due to wear and to increase the smoothness of the surface of the magnetic card.

FIG. 1B shows another example of the magnetic card of the present invention, in which the magnetism 113 is attached to the oversheet 1b1.
It is completely the same as the example shown in FIG. 1A, except that it is provided over the entire surface.

The lower limit of the thickness of the colored layer 5, the pattern layer 6, and the protective FIJ 7 is limited by the robustness, the hiding ability of the magnetic layer 3, the clarity of the pattern, etc., and the upper limit is limited by the magnetic properties such as read output or printing properties. Limited by perspective. As long as the thickness is within the above range, the decrease in magnetic properties is tolerable in practice. In addition, coloring W!
J5 may itself have a B81 construction. Furthermore, an anchor coat layer (not shown) may be provided between each laminated layer in order to increase adhesive strength.

The magnetic card of the present invention described above can be formed, for example, by the following method.

According to the first method, as shown in FIG. 3, first, on the surface of a polyethylene terephthalate film 8 that forms a temporary support, a protective layer is formed by applying, for example, an acrylic resin varnish that is highly durable and has pressability. 7 is applied by gravure printing (plate depth 20 μm), and on top of this protective layer, a pigment or dye of a desired hue is dissolved or dispersed in a liquid medium together with a binder mainly composed of any natural or synthetic resin, such as polyamide resin. A pattern layer 6 consisting of characters, marks, tints, etc. is provided using a gravure stamp @ (plate depth 25 μTrL) using a colored ink made of the following methods, with only the upper layer of the visible information portion as a non-printing portion.

When providing a pattern layer, offset printing or silk screen printing can also be used using an acrylic resin or the like as a binder. Next, the colored WJ5 containing metal powder is similarly gravure printed on the pattern Fi6.

Coloring 115 is printed at a plate depth of 40 to 50 μm using, for example, gravure ink containing metal powder that is highly opaque to the desired color.
It is obtained by gravure printing several times with m. The metal powder contained in the colored layer can be appropriately selected depending on the desired appearance, but in particular, A I , Cu, AU, Ag
, brass, or a blended powder thereof is preferably used. Furthermore, other pigments or dyes can be contained as necessary. For example, when an n-color layer is formed using AI powder, the following composition is preferably used for gravure ink.
