It is known that the surface of the substrate is treated with an antibacterial / antifungal substance by a dry method such as ion implantation, vapor deposition, or thermal spraying. For example, in Japanese Patent Publication No. 4-16179, an active substance that has been ionized or radicalized in advance is ion-implanted into a base material such as synthetic resin, rubber, synthetic fiber, or ceramics. The injected active substance suppresses bacterial growth and keeps the surface of the substrate hygienic. JP-A-3-2135
In Japanese Patent Publication No. 09, an antibacterial fiber is manufactured by melt spinning a polymer having an antibacterial substance attached to the surface thereof by a dry method such as vacuum deposition, thermal spraying, sputtering, and ion plating.

Ａｇと併用している。The conventional methods for imparting antibacterial and antifungal properties are as follows:
It relies on the action of antibacterial and antifungal agents that elute from the surface of the base material into the atmosphere. Therefore, in order to obtain excellent antibacterial and antifungal properties, it is required to expose the antibacterial and antifungal substance over a wide range of the substrate surface as much as possible. But,
If the antibacterial / antifungal agent is kneaded or ion-implanted on the surface of the base material in such a state, strict control of operating conditions is required, resulting in deterioration of workability. The methods such as coating, vapor deposition, and thermal spraying have drawbacks such that the active ingredient is unnecessarily eluted and the film peels off from the substrate. Therefore, it is difficult to maintain good antibacterial and antifungal properties for a long period of time. antibacterial·
Antifungal agents include poisonous substances due to their properties. Therefore, even if the substance exhibits strong antibacterial and antifungal properties, it is not preferable that it has a bad influence on the human body due to elution or the like. Therefore, recently, safe and environmentally friendly antibacterial and antifungal treatments have been desired. On the other hand, with organic drugs, antibacterial
When it loses its antifungal properties, it easily becomes a nutrient source for bacteria,
On the contrary, it may promote the reproduction of bacteria. For these reasons, Ag has attracted attention as an antibacterial / antifungal agent as a substance having excellent antibacterial / antifungal properties and high safety, and an inorganic antibacterial / antifungal agent carrying Ag has been developed. For example, in JP-A-3-172113, Ag ions are carried on the surface of a sparingly soluble phosphate, and Ti, Zr, Z
A phosphate-based antibacterial agent coated with n or the like has been introduced. Ag is a material that has been used as tableware, ornaments, etc., and is highly reliable in terms of safety. Further, in Japanese Patent Laid-Open No. 6-65012, TiO 2 having a function as a photocatalyst is used in combination with Ag in order to improve the durability of antibacterial / antifungal action.

的とする。When a TiO 2 based coating is applied, firing is repeated in order to improve the adhesion to the substrate. However, repeated firing necessitates a labor-intensive and time-consuming working process. Further, since the treatment is performed at a high temperature, the material of the treatable base material is restricted. As a method for solving the problem caused by firing, there is a method of immersing the base material on which the titanium oxide film is formed in an Ag ion-containing liquid or applying the Ag ion-containing liquid to the titanium oxide film and firing. However, in the case of supporting Ag ions by such a method, the adhesion is weak, and wasteful elution of Ag cannot be avoided. Therefore, the durability of antibacterial / antifungal action is not improved as expected. The present invention has been devised to solve such a problem, and by utilizing the fact that a vapor deposition film formed by an ion beam assisted vapor deposition method exhibits excellent adhesion and activity, The purpose is to obtain an antibacterial and antifungal coating having excellent adhesion, which maintains antibacterial and antifungal properties for a long period of time regardless of elution.

It is melted by an electron beam and sent to the surface of the substrate as vapor. The ion beam is generated by ionizing Ar, He or the like with an ion gun and applying an acceleration voltage of 0.1 kV or more. For vapor deposition of Ti, there is a method of using a beam obtained by ionizing oxygen gas. in this case,
During the vapor deposition, Ti is oxidized and deposited as TiO 2 on the substrate surface. Alternatively, TiO 2 can be deposited by supporting an ion beam such as Ar. TiO 2 has a function as a photocatalyst that produces a strong redox effect by generating electrons and holes upon irradiation with light, and therefore promotes the production of active oxygen and cooperates with Ag to prevent antibacterial and antibacterial action. Remarkably improves moldability. Such an effect becomes remarkable when the film thickness of TiO 2 is 0.01 to 1 μm. Also, T

It has the same function as a photocatalyst like O 2 . An ion beam obtained by ionizing O 2 , Ar, He or the like can be used for vapor deposition of these platinum group elements, and the vapor deposition film is preferably formed with a film thickness of 0.01 to 0.5 μm. O
The ion beam that ionizes 2 , Ar, He, etc. is Ag
It is also used when forming a vapor deposition film. Ag formed
Since the vapor deposition film is formed by the ion beam assisted vapor deposition method, it has excellent adhesion to the base material and Ag is not eluted. The Ag vapor deposition film preferably has a film thickness of 0.01 to 1 μm. Since the formed vapor deposition film is vapor-deposited on the surface of the base material activated by the irradiation of the ion beam, the adhesion to the base material is extremely high. In addition, Ag, TiO 2 , platinum group elements, etc. of the deposited film are
It exhibits a catalytic action to generate active oxygen from oxygen in the air and oxygen in water. The generated active oxygen destroys cell membranes of fungi and mold in the vicinity, and kills various bacteria and mold. Therefore, unlike the conventional antibacterial and antifungal treatment which depends on the eluted Ag ions, the excellent antibacterial and antifungal action continues for a long period of time. Moreover, since the substance exhibiting antibacterial and antifungal properties is not eluted, there is no discoloration on the surface of the substrate even after long-term use.

It is presumed that it can be obtained by exhibiting a strong effect by the synergistic effect of the combination of g, TiO 2 , platinum group elements and the like. Such a catalytic action can be achieved by P deposition such as vacuum deposition or thermal spraying.
Although it is also found in the Ag thin film formed by the VD method, since the input energy is smaller than that in the ion beam assisted vapor deposition method, the amount of active oxygen generated from the catalyzed Ag is small.
Further, the formed thin film has poor adhesion to the base material, and cannot withstand a harsh use environment. Moreover, in the ion beam assisted vapor deposition method, the base material is treated at a relatively low temperature, so that the base material is not adversely affected by heating. A

Therefore, the base material surface does not discolor even after long-term use.

Escherichia coli and Staphylococcus aureus were each cultured in an nt broth medium at 25 ° C. for 20 hours, and the culture solution was diluted with an 800-fold dilution of 0.5 M phosphate buffer (pH 7.2) to about 1 to 2 × 1.
A test bacterial solution was prepared by diluting the bacterial solution of 0 4 cells / ml. Put 10 ml of the test bacterial solution together with each test piece into an Erlenmeyer flask,
Shake at 180 rpm for 1 hour. The viable cell count before and after shaking was measured by the plate dilution method, and the bacterial reduction rate was calculated. The bacterial reduction rate is
When the viable cell count before shaking is A and the viable cell count after shaking is B,
It was represented by (A−B) / A × 100 (%). Bacteria reduction rate is 3
When it exceeds 0%, it is evaluated that effective antibacterial properties are exhibited. The test results are shown in Table 1 and Table 2 for E. coli and S. aureus, respectively. In addition, Tables 1 and 2 also show the elution amount of Ag calculated by measuring the surface of the test piece after shaking for 1 hour by an atomic absorption method.

In addition, the elution amount of Ag is 0.0, in which substantially no elution is observed.
