Magnetic transfer foil is made by attaching a peelable magnetic layer to a base film such as polyester, and then forming an adhesive layer.The magnetic transfer foil and adhesive layer are transferred to a card or bankbook, and the base film is then removed. It can be peeled off to produce magnetic cards and magnetic passbooks.

A conventionally painted magnetic transfer foil is as shown in FIG. It has a layer structure like this. The shading layer 4 can be formed by (a) applying a paint containing a white pigment such as titanium oxide, (b) depositing a metal, (c) applying a paint containing a colored pigment with a large shading power. (d) Among these (a) to (c), there is a method of laminating two or more layers.

However, in methods (a) and (c), it is necessary to apply a relatively thick coating in order to obtain sufficient shielding properties, and in method (b), after the deposition, the deposited metal is not covered by air or moisture. It is necessary to form an anticorrosive resin layer to prevent deterioration. In any case, the shielding layer requires a certain thickness.

However, as is well known, the magnetic portion of a magnetic card or magnetic passbook comes into contact with a magnetic head to read the recorded information. Therefore, the distance between the magnetic head and the magnetic powder layer is usually required to be 4 microns or less, and at most 8 microns at most.
