Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a magnetic card which is formed by printing a display unit on a substrate made of a non-magnetic material such as plastic and is mainly applied to telephone cards and the like.

[Prior Art] In recent years, various ID (identification) cards have been developed and widely spread. In particular, magnetic cards have been actively developed, and there are magnetic cards of the full magnetic type in which a magnetic recording layer is provided on the entire surface of a substrate. Further, in the case of a telephone card, which is an example of such a full-face magnetic type magnetic card, it is desired that it is particularly thin and lightweight. As a substrate material of such a thin magnetic card, plastic is used in consideration of strength when carried, and a display portion is formed on the surface of the substrate. This display unit is provided to make the user recognize the purpose of using the card or to make another advertisement.

By the way, regarding the manufacturing process of such a magnetic card, particularly when the display unit is formed by printing on a plastic substrate,
The display part is peeled off, or the chemical resistance of the substrate becomes a problem. Therefore, in order to solve such problems and to provide an affinity between the substrate and the display portion, the display portion is printed by applying a thermoplastic anchor cord material on the substrate.

[Problems to be Solved by the Invention] However, when manufacturing the above magnetic card,
Since the anchor cord material has thermoplasticity, stickiness may occur depending on the ambient temperature. Such stickiness not only makes it difficult to form a print on the display unit, but also deteriorates the yield of products.

The present invention has been made to solve such a problem, and its technical problem is that the print formation of the display unit can be easily performed while ensuring the chemical resistance quality assurance for the plastic substrate. It is to provide a thin magnetic card that can be manufactured at high cost.

[Means for Solving Problems] According to the present invention, a substrate made of a non-magnetic material, and a film made of a resin obtained by adding a thermosetting agent to a thermoplastic resin while forming a film on the substrate surface A magnetic card including a layer and a display portion formed in a predetermined pattern on the coating layer with a resin ink based on a thermosetting resin is obtained. In this magnetic card, it is preferable that the non-magnetic material is a plastic film.

[Examples] Examples of the magnetic card of the present invention will be given below.
A detailed description will be given with reference to the drawings. FIG. 1 is a side view showing the basic structure of a magnetic card according to an embodiment of the present invention.

This magnetic card includes a substrate 1 made of a non-magnetic plastic film, and a coating layer 2 formed on one surface of the substrate 1 and made of a resin obtained by adding a thermosetting agent to a thermoplastic resin. , A display portion 3 formed in a predetermined pattern on the coating layer 2 by a resin ink based on a thermosetting resin such as a thermosetting oxidative polymerization resin or an ultraviolet curable resin, and on the other surface of the substrate 1. Layered magnetic recording layer 4
And consists of.

Here, as the non-magnetic material for the substrate 1, a polyethylene terephthalate (PET) plastic film may be used. Further, a vinyl chloride copolymer or an amorphous polyester resin may be used as the thermoplastic resin material of the coating layer 2, and an isocyanate group or a polyurethane resin to which an isocyanate compound is added as the thermosetting agent. Should be used. In forming the coating layer 2, if a thermosetting agent is added to such a thermoplastic resin material and thermosetting is performed, the same curability can be obtained.

The heat curing treatment here is important in the process of manufacturing the card, and the coating layer 2 positioned as the intermediate layer can ensure the chemical resistance quality of the plastic substrate 1, and also the substrate 1 and the display unit 3. Since it is possible to give affinity to both, it is effective in improving the quality in the card manufacturing.

After that, the display portion 3 is printed and formed in a predetermined pattern on the coating layer 2 by offset printing, silk printing or the like using a resin ink based on a thermosetting oxidative polymerizable resin or an ultraviolet curable resin. .

In such a magnetic card, since the coating layer 2 made of a resin made by adding a thermosetting agent to a thermoplastic resin is laminated on the plastic film substrate 1, the display unit 3
Since the coating layer 2 is stably formed without being thermally deformed if the temperature change is about room temperature change during the print formation, the display can be performed as desired, and the adhesive strength of each part is strengthened to improve the mechanical strength. It has excellent strength.

[Advantages of the Invention] As described above, according to the present invention, since the plastic substrate is provided with the coating layer made of the resin formed by adding the thermosetting agent to the thermoplastic resin, The chemical resistance is guaranteed, and the adhesive strength to the substrate and the display is strengthened so that the display can be printed well, and it is not easily affected by temperature changes, making it possible to manufacture high-quality thin magnetic cards with good yield. become.
