ともあり得る。Magnetic cards whose personal information can be easily identified are widely used in business fields other than the financial field. For example, in the medical field, a magnetic card is issued instead of a medical examination ticket, which is used for rationalizing medical office work such as reception office work, search for medical history, and settlement of medical expenses. In this way, in the usage pattern in which the magnetic card is transferred between the owner and another person, it is inevitable that another person other than the owner touches the magnetic card. In many cases, there is no problem in touching the magnetic card by someone other than the owner. However, in hospitals and the like, the magnetic card may be contaminated with pathogenic bacteria by handing over the card, and in the worst case, the magnetic card may be affected. The magnetic card may be contaminated by using the card reader installed in the hospital.

However, if the antibacterial layer 6 is formed on the outer surface of the card, even if nutrients such as hand dust and sebum adhere to the outer surface of the antibacterial layer 6, bacteria and the like cannot proliferate and their growth can be prevented. At this point, the antibacterial mechanism of the antibacterial agent 5 has not been sufficiently clarified, and only some theories have been proposed. However, it has been experimentally or empirically confirmed that the antibacterial agent 5 is effective, and for example, ballpoint pens, household electric appliances, socks, etc. having an antibacterial effect are put into practical use.

The antibacterial layer 6 can be easily formed even if the magnetic card is punched from the magnetic card. The antibacterial layer 6 can be newly formed even with a magnetic card having a reduced antibacterial effect or a magnetic card that has already been issued. The antibacterial layer 6 formed by using the printing ink as a dispersion medium of the antibacterial agent 5 also has the same operation and effect as in the case where the above-mentioned coating material is used as the dispersion medium. It is also possible to increase the exposed area of the antibacterial agent 5 by roughening the antibacterial layer 6 during or after the printing process.

It is possible and advantageous in that it is harmless to the human body. The antibacterial layer 6 is formed transparent in order to prevent the display of the printed layer 2 from being hidden by the antibacterial layer 6. According to the magnetic card in which the transparent plastic film containing the antibacterial agent 5 is laminated on the outer surface of the card to form the antibacterial layer 6, the antibacterial layer 6 is locally peeled off, and scratches due to contact with other objects are well performed. It is possible to prevent and improve the durability of the antibacterial layer 6 during long-term use.

形成するためのコストを減らすことができる。The antibacterial agent 5 may be either an organic antibacterial agent or an inorganic antibacterial agent, but the antibacterial effect can be maintained for a long period of time, the heat resistance is excellent, and the antibacterial agent is harmless to the human body. It is preferable to use an inorganic antibacterial agent. The inorganic antibacterial agent is composed of a powder in which a metal or a metal ion is held in a carrier, a powder in which silver ion is supported on zeolite, a minus silver ion is bound to silica gel, and the surface thereof is coated with silica sol, zirconium. A commercially available antibacterial agent such as a powder obtained by substituting a part of hydrogen ions in the compound with silver ions and then baked, a powder obtained by sintering calcium phosphate and silver, a powder obtained by retaining silver ions on apatite-based ceramics, etc. Applicable. An inorganic antibacterial agent containing copper or gold other than silver as an antibacterial active species may be used. When the antibacterial layer 6 is formed by printing, the thickness of the antibacterial layer 6 is reduced as compared with the case where the antibacterial layer 6 is formed by applying a paint, and the amount of the antibacterial agent used is reduced accordingly. The cost for forming the antibacterial layer 6 can be reduced.

There, a protective film is laminated on the front and back of the card body 1 to form protective layers 3 and 3, a magnetic sheet 4 is attached to a predetermined position of the protective layer 3 on the front side, and a printing layer 2 is further provided on the outer surface thereof. Once formed, the magnetic card was formed as a concealed card. Then, an antibacterial layer 6 containing an antibacterial agent 5 was formed on each of the front surface and the back surface of the card in the same manner as in Example 1. The surface area of the antibacterial agent 6 exposed on the surface of the antibacterial layer 6 can be increased by roughening the surface of the antibacterial layer 6 when the antibacterial layer 6 is formed by coating or printing, or after the antibacterial layer 6 is formed. . This means
It also helps to reduce the amount of the antibacterial agent 5 used, and is advantageous in that the antibacterial layer 6 can be formed at a lower cost when a noble metal such as silver or gold is used as the antibacterial active species.

The magnetic card before forming the antibacterial layer 6 may be any of the magnetic cards described in the first and second embodiments. The plastic film containing the antibacterial agent 5 is formed transparent. Specifically, the film used is made of a transparent plastic material, and the particle size of the antibacterial agent 5 is reduced to 0.1 to 1 μm to enhance the dispersibility of the antibacterial agent 5 in the film. An example is an antibacterial agent in which apatite-based ceramics retain silver ions.
