Abstract

PURPOSE: To obtain a magnetic card capable of appreciating the feel of natural wood by laminating veneer to at least the single surface of a magnetic card body becoming a magnetic memory element through an adhesive. CONSTITUTION: Veneer 2 is laminated to the single surface of a magnetic card body 1 becoming a magnetic memory element through an adhesive 3. The veneer 2 is obtained by slicing material wood of a hinoki or a cedar and immersing the slice wood, for example, in a chlorine type bleaching agent and drying the treated wood. Immersion treatment is executed in order to remove bacteria present on or in the veneer 2 obtained by slicing material wood and to prevent the formation of irregular patterns caused by the generation of fungi or the like. The concn. of the bleaching agent is pref. set to about 2%. The thickness of the veneer is 0.2-0.5 μm, pref., about 0.3-0.4 μm. Since the veneer is laminated to at least the single surface of the magnetic card body becoming the magnetic memory element through the adhesive, the touch of natural wood is provided to a user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] These inventions relate to magnetic cards used for telephone cards, commuter passes, etc., and methods for manufacturing the same.

[Conventional technology]

In recent years, magnetic cards have been applied to various fields.

Examples include telephone cards and commuter passes. Furthermore, in hotels and the like, magnetic cards are increasingly being used as a substitute for door keys.

Generally, the surface of the magnetic card body, which serves as a magnetic storage medium, is coated with resin, paint, or the like to give the above-mentioned magnetic card a decorative effect.

[Problem that the invention seeks to solve]

However, the above-mentioned decoration method using resin or paint gives the user a cold feeling, and may make the user feel uncomfortable as if the window were used in a machine.

In view of these circumstances, the first invention is to provide a magnetic card that has a good feel and appearance and gives warmth to the user, and the second invention is to efficiently use the magnetic card. The purpose is to provide a method for manufacturing.

[Means to solve the problem]

In order to achieve the above objectives, these inventions
The gist of the first invention is a magnetic card in which a veneer veneer is laminated with an adhesive on at least one side of a magnetic card main body that serves as a magnetic storage body, and the second invention provides a magnetic card that serves as a magnetic storage body. To obtain a magnetic card in which a veneer veneer is laminated with an adhesive on at least one side of the card body, a water-soluble emulsion of an acrylic copolymer is applied to at least one side of the magnetic card body and semi-cured. , the gist is a method for manufacturing a magnetic card, characterized in that the veneer veneer is pressure-bonded onto the adhesive.

[For production]

Since the magnetic card according to the first invention is configured as described above, the feel of natural wood can be enjoyed. Also, the second
The magnetic card manufacturing method according to the invention allows the above-mentioned magnetic card to be easily obtained with high precision.

〔Example〕

Hereinafter, embodiments of these inventions will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the magnetic card according to the first invention viewed diagonally from above, and FIG. 2 shows it viewed from the side. As shown in the figure, in the magnetic card according to the first invention, a single veneer board 2 is laminated with an adhesive 3 interposed on one side of a magnetic card body 1 serving as a magnetic storage body.

The veneer veneer 2 is obtained by slicing raw wood such as cypress or cedar, then immersing the slice in, for example, a chlorine bleach and drying. The above-mentioned dipping treatment removes bacteria present on the surface and inside of the veneer veneer 2 sliced from raw wood.
This is done to prevent mold from forming and creating a patchy pattern.

The concentration of bleaching agent is preferably about 2%.

The thickness of the veneer veneer is approximately 0.2 to 0.5 μm, preferably approximately 0.3 to 0.4 μm.

Next, the manufacturing method of a magnetic card according to the second invention will be explained in detail step by step.

(2) Apply a water-soluble acrylic copolymer emulsion as the adhesive 3 to one side of the magnetic card body 1. (2) Allow the adhesive 3 to semi-cure by leaving it to naturally.

■ Place the bleached veneer board 2 on the semi-cured adhesive 3 and press it. At the time of pressure bonding, heat may be applied as necessary to speed up the curing of the adhesive 3.

In addition, acrylic copolymer water-soluble emulsion has good wettability to the magnetic card body and does not cause uneven coating.
The veneer veneer is adhered to the magnetic card body without any gaps.

Magnetic cards can be used for cash coupons such as telephone cards,
Examples include commuter passes9 tickets, card-shaped keys for doors, etc. In addition, on the surface of the veneer veneer, after adhering to the magnetic card body, advertising text or the like in a desired pattern can be printed as necessary.

The magnetic card according to the first invention is not limited to the above embodiment. For example, in the above embodiment, the veneer veneer was laminated only on one side of the magnetic card body, but it may be laminated on both sides.

〔Effect of the invention〕

As described above, the magnetic card according to the first invention has a veneer veneer laminated with an adhesive on at least one side of the magnetic card body, which serves as a magnetic storage body, so that the user can enjoy the natural wood material. It provides texture and provides warmth.

Moreover, it looks very good.

As described above, the method for manufacturing a magnetic card according to the second invention includes the steps of magnetic After a water-soluble acrylic copolymer emulsion is applied to at least one side of the card body and semi-cured, the veneer veneer is pressed onto the adhesive, so that the magnetic card according to the first invention can be manufactured accurately and efficiently.
