生が認められる。BACKGROUND OF THE INVENTION It is well known that plastics have been widely used in recent years and are used as a constituent material of various products. It is also well known that in Japan, which is exposed to high temperature and high humidity, mold is common. By the way, the growth of fungi such as mold and bacteria is in a humid environment, and since plastic has a relatively low water content, plastic is relatively resistant to mold, but in Japan Then, mold development is recognized even on plastic.

することが出来ていなかった。DISCLOSURE OF THE INVENTION By the way, various antibacterial and antifungal agents have been conventionally known. However, if a conventional antibacterial / antifungal agent is added to a plastic material and this is used as a material and molded into a predetermined shape by a molding means such as injection molding, it seems that this is due to the heat at the time of molding, The antibacterial and antifungal effects were largely lost, and the development of fungi could not be effectively prevented.

ることである。As a result of further research and development based on these things, the resin containing zinc sulfate or zinc borate has a good antibacterial and antifungal effect, and is It was found that the occurrence was effectively prevented. The present invention has been achieved based on such knowledge,
An object of the present invention is to provide a resin product in which mold and the like are unlikely to propagate.

０．７〜２重量％であることが好ましい。The object of the present invention is characterized in that at least one selected from the group consisting of zinc sulfate and zinc borate is interposed, and the total amount of inclusion is 0.5 to 5% by weight. Achieved by antibacterial and antifungal resin products. The intervening amount of zinc sulfate or zinc borate is preferably about 1 to 5% by weight, more preferably about 1 to 3% by weight.
When both zinc sulfate and zinc borate are used, the intervening amount is preferably about 0.5 to 3% by weight, more preferably about 0.7 to 2% by weight.

に至り、所望の目的が達成されるようになる。Although any form of zinc sulfate or zinc borate may be present, it is preferable that zinc sulfate or zinc borate is mixed in the resin. That is, if only zinc sulfate or zinc borate is attached to the surface of the resin, it will be removed by washing or rubbing, and the durability will deteriorate. On the other hand, when it is mixed in the resin, zinc sulfate and zinc borate are not substantially lost, and the durability is high. If only that, or fungi such as mold have not penetrated into the resin, it can be removed by wiping it off,
Treatment for such mold is easy. Therefore, it is sufficient that the fungus such as mold is prevented from entering the inside of the resin. From this viewpoint, it is preferable that zinc sulfate or zinc borate is mixed in the resin. Further, according to such a configuration, even if a mold is generated and attempts to reproduce, extension of the legs into the resin is blocked by zinc sulfate or zinc borate, does not reproduce, and eventually leads to death. The purpose of will be achieved.
