性粉の歩合（割）を示す。The pencil scratch value was H and the peeling and cross-cart peeling was 0. The obtained color is a grayish color and the notice is clearly visible. Next, the ratios of the magnetic powder and TiO 2 in the above mixing ratio were changed, and the results shown in FIGS. 2 and 3 were obtained. Here, the magnetic powder ratio indicates the ratio (percentage) of the magnetic powder when the total amount of the magnetic powder, the white pigment, and the carbon is 10.
第２図で示されるように、顔料中の磁性粉比率が5.0
以下では、出力（Ф/t,Фは磁束；マクスウェル,tは磁
気記録層の厚さ;cm）が小さくなり、磁気記録層として
は不適であった。As shown in Fig. 2, the ratio of magnetic powder in the pigment is 5.0.
Below, the output (Φ / t, Φ is the magnetic flux; Maxwell, t is the thickness of the magnetic recording layer; cm) was small, and it was unsuitable for the magnetic recording layer.
また，第３図に示されるように、顔料中の磁性粉比率
が6.0より大なる場合は、表面が黒くなり印刷が不明瞭
となった。Further, as shown in FIG. 3, when the ratio of the magnetic powder in the pigment was more than 6.0, the surface became black and the printing became unclear.
従って，印刷可能な磁気記録層として使用できる範囲
は，顔料中の磁性粉比率＝5.00〜6.00である。Therefore, the range that can be used as the printable magnetic recording layer is the magnetic powder ratio in the pigment = 5.00 to 6.00.
また，帯電防止のために入れるカーボン量は,3％程度
で効果がある。In addition, the amount of carbon added for antistatic is about 3%, which is effective.
