〔産業上の利用分野〕
近年、テレホンカード、オレンジカードあるいはその他
民鉄カード等の料金前払いのいわゆるプリペイドカード
が広く普及している。本発明は、これらのプリペイドカ
ードを含むカードのうちで、サーマルヘッドを用いて可
視情報を記録可能なカードに関する。[Detailed Description of the Invention] [Industrial Application Field] In recent years, so-called prepaid cards such as telephone cards, orange cards, and other private railway cards have become widely used. The present invention relates to cards that can record visible information using a thermal head, among cards including these prepaid cards.
低融点金属からなる感熱記録層を有したプリペイドカー
ドの印字は、加熱によって金属が溶融し、表面張力によ
って球状になることを利用している。しかし、単に低融
点金属薄膜層を設けるのみでは、その表面が光沢を有す
るために、印字の視認性が悪いことから、低融点金属薄
膜層の下層（以下アンカー層と呼ぶ）に粒径数μｍの微
細粒子を混入し、低融点金属薄膜層の表面を粗面化する
ことによって光沢を減少させ、視認性を改善する方法が
提案されている。Printing on prepaid cards that have a heat-sensitive recording layer made of a low-melting point metal utilizes the fact that the metal melts when heated and becomes spherical due to surface tension. However, simply providing a low melting point metal thin film layer has a glossy surface, which makes the visibility of the print poor. A method has been proposed for reducing gloss and improving visibility by roughening the surface of a low melting point metal thin film layer by mixing fine particles of .
しかしながら、微細粒子を混入すると、明らかに印字感
度が低下する。その理由はい（つか考えられる。一つは
、微細粒子の混入によって下層の熱伝導度が増すために
、本来金属薄膜を溶融するために必要な熱がアンカー層
から磁気記録層へと流出しているためという考え方であ
る。あるいは、混入した微細粒子と薄膜を形成している
金属との親和性が強いため、加熱しても溶融した金属が
移動しにくくなっているということも考えられる。However, when fine particles are mixed, printing sensitivity clearly decreases. Is there a reason for this? (There are several possible reasons. One is that the thermal conductivity of the lower layer increases due to the inclusion of fine particles, so that the heat normally required to melt the metal thin film leaks from the anchor layer to the magnetic recording layer. Another possibility is that the mixed fine particles have a strong affinity with the metal forming the thin film, making it difficult for the molten metal to move even when heated.
いずれにしても微細粒子を混入するのは印字感度を低下
させるので、良質な印字を得るのは困難になる。In any case, mixing fine particles reduces printing sensitivity, making it difficult to obtain high-quality printing.
こうした状況を鑑み、本発明は、微細粒子を混入するこ
となく低融点金属薄膜の表面を粗面化し、可視情報の視
認性を改善することを課題とする。In view of these circumstances, an object of the present invention is to improve the visibility of visible information by roughening the surface of a low-melting metal thin film without mixing fine particles.
〔課題を解決するための手段］
上記の目的を達成するため、本発明のプリペイドカード
は、相溶性に劣る２種類以上の樹脂を混合することでア
ンカー層表面を粗面化することを特徴とする。[Means for Solving the Problems] In order to achieve the above object, the prepaid card of the present invention is characterized in that the surface of the anchor layer is roughened by mixing two or more types of resins with poor compatibility. do.
樹脂が相溶している状態とは、樹脂の分子鎖がお互いに
十分に延びきって寄り添うかたちになっている状態であ
り、これを塗工ずれば、均質な、光沢のある表面が得ら
れる。逆に言うなら、相溶性に劣る樹脂を混合すれば、
いずれかの成分が液中で延びきらず、不均質な状態にな
るはずである。A state in which the resins are compatible is a state in which the molecular chains of the resins are fully extended and nestled together, and if this is applied, a homogeneous and glossy surface can be obtained. . Conversely, if you mix resins with poor compatibility,
One of the components cannot fully extend in the liquid, resulting in a non-uniform state.
実際に、例えばポリエステル樹脂とポリオレフィン樹脂
、ポリウレタン樹脂、塩化ビニル−酢酸ビニル共重合樹
脂等を混合すると白濁し、均質でないことがわかる。こ
れを塗工したところ、均質でない、すなわち表面性の悪
い塗膜面を得ることができた。しかも、その表面は実際
に目視でもマット調であった。In fact, for example, when a polyester resin, a polyolefin resin, a polyurethane resin, a vinyl chloride-vinyl acetate copolymer resin, etc. are mixed, the resulting mixture becomes cloudy and is not homogeneous. When this was applied, it was possible to obtain a coating surface that was not homogeneous, that is, had poor surface properties. Moreover, the surface was actually matte-like when visually observed.
以上のようなアンカー層の上に低融点金属薄膜層を設け
ることにより、かかる低融点金属薄膜層の表面をマット
化し、全体として光沢がなく視認性に優れるカードを得
ることが可能である。By providing a low melting point metal thin film layer on the anchor layer as described above, the surface of the low melting point metal thin film layer can be made matte, and it is possible to obtain a card that is not glossy as a whole and has excellent visibility.

とが可能となる。(Function) According to the present invention, it is possible to provide a card with good visibility without lowering the printing sensitivity compared to the conventional cards.

以下、本発明の実施例について図面を参照して詳細に説

、保護層６のように構成されている。FIG. 1 is a schematic sectional view showing the structure of the prepaid card of the present invention. 1 is a prepaid card, which consists of a base material 2, a magnetic recording layer 3, an anchor layer 4, and a low melting point metal thin film layer 5 in this order.

A magnetic recording layer 3 is formed using a magnetic paint in which a magnetic material is dispersed in a resin, and after drying and curing the magnetic recording layer 3, an anchor layer 4 is provided thereon.

共重合樹脂といったような樹脂の組合せの中で、相溶性
の悪い組合せを選んで使用することができる。For the anchor layer 4, two or more types of resins having poor compatibility are mixed so that the surface has a matte property during coating. Of course, from the viewpoint of durability of the prepaid card 1, the anchor layer 4 needs to have excellent adhesion to both the magnetic recording layer 3 and the low melting point metal thin film layer 5. For example, among combinations of resins such as polyester resins, urethane resins, acrylic resins, acrylic polyol resins, polyolefin resins, and vinyl chloride-vinyl acetate copolymer resins, combinations with poor compatibility can be selected and used.

A thickly coated material was used. As the anchor layer 4,
Polyester resin Chemit -588 (manufactured by Toshi ■), vinyl chloride-vinyl acetate copolymer resin VAGH (manufactured by Union Carbide ■), urethane resin Niboran 2304 (
Using a mixture of three types (manufactured by Nippon Polyurethane Industries) in a ratio of 2:1:1, 2μ was coated using the gravure coating method.
It was coated to a thickness of m. The low melting point metal thin film layer 5 is made of Sn (purity 99
．． 99%) commercially available product is vapor-deposited to a thickness of 400λ, and then acrylic resin TR-15 (
(manufactured by Dainippon Ink & Chemicals) to 1.5 μm using the gravure method.
It was coated thickly. For comparison, the resin of anchor layer 4 is
-588 (described above) alone was also used as Chemit.
以上のものをカード状に打ち抜いて、アンカー層４表面

かる。The above material was punched out into a card shape, and the 10-point average roughness of the surface of the anchor layer 4 and the surface of the protective layer 60 was measured. The results are shown in Table 1. As can be seen from this result,
The sample using the mixed resin as the anchor layer 4 is
It can be seen that the 10-point average roughness values of the surface of the anchor layer and the surface of the protective layer 6 are large, so that the surface has a matte appearance.
目視でも明らかに混合樹脂のアンカー層４の方が視認性

、樹脂を混合したために印字感度が低下するような現象
は見られなかった。Visually, it is clear that the anchor layer 4 made of mixed resin has better visibility. Additionally, when we compared the two under the same printing conditions, we did not see any decrease in printing sensitivity due to the resin mixture.
