DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a card holder for protecting cards containing magnetic recording media, such as bank cards and telephone cards.

Currently, in order to prevent bank cards, etc. that store information magnetically, from being magnetically destroyed due to contact with permanent magnets, magnetic shielding plates such as iron plates and permalloy are laminated with synthetic or natural leather. Signs, card holders, etc. are commercially available using this material as the outer skin.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

しかしながら、これら従来のカード入れは磁気シールド

However, although these conventional card holders have a sufficient magnetic shielding effect, they are as thick as 2 cranes and have a rigid magnetic shielding plate, so they do not feel good against the skin when placed in a commercially available pocket. Alternatively, the parts of the combined leather or natural leather that are in strong contact with the magnetic shielding plate may be torn.

As soft magnetic particles, soft ferrite such as Ni-Zn+Mn-Zn is advantageous because it is easily obtained as fine particles with an average particle size of about 0.1 μm to 5 μm, but fine magnetic metal particles prepared by molten metal quenching method are advantageous. But it's okay. Fine particles with a particle size smaller than 0.1 μm are difficult to produce because the particle size is too small, and are not practical. On the other hand, if the average particle size is larger than 10 μm, compatibility with the polymeric binder becomes poor, so the particle size of the magnetic particles bound by the polymeric binder is preferably 0.1 μm to 10 μm. The volume ratio of the magnetic particles to the total volume of the magnetic particles and the polymeric binder is 5.
0-80% is good. If the volume ratio is less than 50%, a sufficient magnetic shielding effect cannot be obtained, while if it is more than 80%, elasticity is lost and the card holder feels uncomfortable against the skin when placed in a pocket.
