00〜400ミクロン、テーバー剛度MDで３〜15g・cm、TDで
12〜20g・cm、表面強度250〜400g・cm〕 が用いられている。The resin base material of the card 1 includes: (a) polyvinyl chloride sheet containing inorganic fine powder (so-called “salt white”, density 1.4 g / cm 3 , wall thickness 500 to 1000 μm, Taber stiffness (S value)) 60gcm or more, (b) Thermoplastic polyester resin sheet containing inorganic fine powder (density 1.5g / cm 3 , wall thickness 200-300 microns, Taber stiffness 20-55gcm) (c) Inorganic fine powder Paper made of stretched polypropylene sheet (so-called Oji Yuka Synthetic Paper Co., Ltd.)
Made "YUPO EPG" (trade name), density 0.77 to 0.83 g / cm 3 , wall thickness 2
00-400 microns, Taber stiffness MD 3-15gcm, TD
12 to 20 g · cm, surface strength of 250 to 400 g · cm] is used.
しかし、（イ）の塩白については、焼却時の塩素ガス、
塩酸発生による大気汚染が懸念されるとともに、重量が
重い。かつ、可塑剤のブリードアウトによる誤読も懸念
される。However, for the salt white of (a), chlorine gas at the time of incineration,
There is concern about air pollution due to the generation of hydrochloric acid, and the weight is heavy. At the same time, there is concern about misreading due to bleeding out of the plasticizer.
（ロ）のポリエステル樹脂シートは、寸法安定性に優
れ、無公害性に優れるがコストが高い欠点がある。The polyester resin sheet (b) has excellent dimensional stability and excellent pollution resistance, but has the drawback of high cost.
（ハ）のポリプロピレン系合成紙は無公害であり、コス
トも一番安価である利点を有するが、汎用の磁気読み取
り装置がポリエステル樹脂シートを基材とした情報記録
カード用であるので、この装置の給紙、排紙機能に適合

肉厚を熱くする必要がある。又、表面強度が低いので、
この基材の上に磁気ストリップを接着剤で貼着した後、
この情報記録カードを読み取り機にかけた際、何らかの
原因で剥離応力がこの磁気ストリップにかかったとき、
基材表面が剥離する可能性がある。The polypropylene-based synthetic paper of (C) has the advantage of being non-polluting and cheapest in cost, but since a general-purpose magnetic reading device is for information recording cards using a polyester resin sheet as a base material, this device is used. In order to adapt to the paper feeding and paper discharging functions of, it is necessary to heat the thickness of the synthetic paper in order to increase the Taber rigidity. Also, since the surface strength is low,
After sticking the magnetic strip on this substrate with an adhesive,
When this information recording card is put on a reader and peeling stress is applied to this magnetic strip for some reason,
The base material surface may peel off.

じ肉厚の密度が0.77g/cm3のポリプロピレン系合成紙の
テーバー剛度は、約270ミクロンで21g・cm、約200ミク
ロンで11g・cmであり低い。For example, a telephone card with a wall thickness of 274 microns made of polyester (PET), which has high rigidity of the resin itself, has a Taber stiffness of 51.5 gcm, and a JR orange card with a thickness of 212 microns has a Taber stiffness of 22.5 g.・ It is cm. The Taber stiffness of polypropylene-based synthetic paper having the same wall thickness and density of 0.77 g / cm 3 is 21 g · cm at about 270 μm and 11 g · cm at about 200 μm, which is low.
このポリプロピレン系合成紙のテーバー剛度の低いこと
は、素材のポリプロピレン自身がポリエステルよりも剛
性が低いことと、ポリプロピレン系合成紙が軽量化のた
めにフィルム内部に微細なクイクロボイドを多数有する
ことに起因する。The low Taber rigidity of this polypropylene-based synthetic paper is due to the fact that the polypropylene itself, which is a material, has a lower rigidity than polyester, and that the polypropylene-based synthetic paper has many fine quiclovoids inside the film for weight reduction. .
即ち、無機微細粉末含有ポリプロピレンフィルムをポリ
プロピレンの融点よりも低い温度で延伸するとフィルム
内部には無機微細粉末を核にマイクロボイドが多数発生

粉末との配合化、延伸温度、延伸倍率等に起因し、無機
微細粉末が多い程、延伸温度が低い程、延伸倍率が高い
程マイクロボイドの発生量は多く、密度は小さくなり
（より軽量化）、表面はより粗くなる。That is, when a polypropylene film containing inorganic fine powder is stretched at a temperature lower than the melting point of polypropylene, a large number of microvoids are generated in the inside of the film due to the core of the inorganic fine powder, many cracks are generated on the film surface, and the weight of the card is reduced. And the adhesive strength and printability are improved. The surface roughness and the amount of microvoids are due to the blending of polypropylene and the inorganic fine powder, the stretching temperature, the stretching ratio, etc., the more the inorganic fine powder, the lower the stretching temperature, the higher the stretching ratio. The amount of microvoids generated is high, the density is low (lighter), and the surface is rougher.
