本発明は磁気カードおよびその製造方法に関す

カード、音声入り磁気カード、料理カードなどに
用いられている。 Conventionally, magnetic cards have generally used a substrate having a sandwich structure in which vinyl chloride film is laminated on both sides of a center core made of plastic such as vinyl chloride or paper. recently,
The applications of magnetic cards are expanding more and more, and they are used not only in cash cards used in banks, but also in data cards, magnetic cards with audio, cooking cards, and the like.

は不適当であろう。さらに低価格磁気カードの要
求に対して十分対応することは困難であろう。 Although vinyl chloride used as a substrate or a film for laminating the same can be relatively easily adhered to a magnetic tape, it may be insufficient in terms of heat resistance, chemical stability, economic efficiency, etc. depending on the purpose. For example, when used in a high temperature place such as a cooking card, there is a concern about thermal deformation. Furthermore, vinyl chloride may be unsuitable for applications requiring chemical resistance and solvent resistance. Furthermore, it would be difficult to adequately meet the demand for low-cost magnetic cards.

は従来用いられていなかつた。 Polyolefin resins such as polypropylene are effective against such problems. Polyolefin resin films are widely used as packaging materials for foods, etc., and their chemical stability and economic efficiency have been proven, but they have problems with adhesion and are used as substrates for products that require reliability, such as magnetic cards. This material has not been previously used.
一般に基体に磁気テープを貼付する方法は、主
として以下の三つが考えられる。 In general, the following three methods can be considered for attaching magnetic tape to a substrate.
(1)熱圧着法(2)感圧接着法(3)接着フイルム法
熱圧着法は磁気テープ裏面にあらかじめ感熱接
着剤を塗布し、接着時に基体と加熱圧着させる方
式である。磁気テープがリールに巻かれた状態で
ブロツキングしないように、接着剤は室温でタツ

は比較的硬いものが用いられるため、ポリオレフ

剥離時にはがれ端での応力集中により、接着剤と
基体の界面から剥離し、十分な強度を得ることは
できない。 (1) Heat-compression bonding method (2) Pressure-sensitive bonding method (3) Adhesive film method The thermo-compression bonding method is a method in which a heat-sensitive adhesive is applied in advance to the back side of the magnetic tape, and the magnetic tape is heat-pressed to the substrate during adhesion. The adhesive is required to be non-tacky at room temperature so that the magnetic tape does not block when wound on a reel. Therefore, since a relatively hard adhesive is used, adhesion to nonpolar substrates such as polyolefin resins is difficult.
During peeling, stress concentration at the peeled edge causes the adhesive to peel from the interface between the adhesive and the base, making it impossible to obtain sufficient strength.
感圧接着法は磁気テープ裏面にあらかじめ感圧

生出力の低下を生じ、トラブルを発生することに
なる。 The pressure-sensitive adhesive method is a method in which a pressure-sensitive adhesive is applied to the back side of the magnetic tape in advance, a release paper is wrapped around it to prevent blocking, and the release paper is peeled off at the time of adhesion and the tape is pressed to the substrate. According to this method, since the magnetic tape is adhered to the substrate by adhesive force, stress concentration at the peeled edge during peeling is alleviated, and the adhesive strength is increased. However, magnetic cards made using this method are subjected to pressure when bonded to a substrate and when information is recorded/reproduced by a magnetic head, causing the adhesive to protrude from the sides of the magnetic tape. This adhesive adheres to the magnetic head during magnetic card recording and reproduction, causing so-called head clogging, resulting in a reduction in reproduction output and trouble.
接着フイルム法は接着時に磁気テープと基体の

容易に磁気テープと接着フイルムの界面から剥離
し、十分な接着強度を得ることはできない。 The adhesive film method is a method in which an adhesive film is inserted between the magnetic tape and the substrate at the time of adhesion, and the two are heated and pressed together. In this method, the interface between the adhesive film and the adherend is difficult to achieve sufficient adhesion compared to the adhesive solution application type, and stress concentration occurs, so it is relatively easy to peel off from the interface between the magnetic tape and the adhesive film. , it is not possible to obtain sufficient adhesive strength.
以上いずれの方法も、ポリオレフイン系樹脂表

に対して有効である。 The polypropylene substrate used in this example was not subjected to any surface treatment. If the substrate is subjected to corona discharge treatment, the adhesive strength will be further increased. However, since the effectiveness of surface treatments such as corona discharge treatment decreases depending on the storage environment and aging, careful attention is required to manage the adhesive strength of magnetic tapes. Therefore, a method capable of adhering sufficiently to untreated substrates, such as the present method, is effective for items that require reliability, such as magnetic cards.
