境性を向上させることを特徴とする。(Example) The present invention is characterized in that by providing a blocking layer between the magnetic recording layer and the metal vapor deposition layer, the effect of preventing the promotion of the reaction is obtained and the environmental resistance is improved.
遮断層としては、磁気記録層及び金属蒸着層の材料に比
べ、比抵抗の高いものが良＜、１０”Ω−ａｎ以上を示
す樹脂が望ましい。また、その厚みとして１μ以上が必
要である。なお、厚みがあつすぎるとカードとしての出
力が小さくなるため２０μ以下が望ましい。The blocking layer is desirably a resin having a resistivity higher than that of the materials of the magnetic recording layer and the metal vapor deposition layer, and exhibiting a resistivity of 10'' Ω-an or more.The thickness thereof must also be 1 μm or more. Note that if the thickness is too thick, the output as a card will be reduced, so the thickness is preferably 20 μm or less.
