Description of the Related Art The sheets, clothes, etc. described above are often used for the purpose of blocking water, but they are usually formed by laminating a vinyl chloride resin layer on a base fabric with an adhesive. There is. Since these sheets and clothes are always exposed to humid conditions due to the nature of their uses, bacteria, molds and the like are easily proliferated and hygienic unfavorable conditions are likely to occur. In order to prevent such a problem, measures such as coating the surface with a treatment agent containing an antibacterial and antifungal agent and using a base cloth containing an antibacterial and antifungal agent have been taken. However, in the case of the coating method, the coating layer is often peeled off and abraded by repeated washing, disinfection, mechanical rubbing, etc., and the antibacterial and antifungal effect is often lowered relatively quickly. On the other hand, when the base cloth contains an antibacterial and antifungal agent, the surface area of the base cloth is large and the elution of the antibacterial and antifungal agent is large due to washing, disinfection, etc. It is necessary to add a large amount of fungicide, resulting in high production cost and safety concerns. In addition, when the antibacterial and antifungal agent is contained only in the vinyl chloride resin layer, there is a problem that the antibacterial and antifungal effect cannot be sufficiently obtained on the base fabric surface side.

Is preferred. If the content of the organic antibacterial and antifungal agent is less than 0.1% by weight, a sufficient amount of the organic antibacterial and antifungal agent cannot be transferred to the base fabric layer. The sexual effect tends to be insufficient. Further, even if it is used in an amount exceeding 5.0% by weight, it is difficult to obtain the effect corresponding to the amount used, and the bloom of the antibacterial / antifungal agent on the surface of the vinyl chloride resin layer tends to increase.

Those added to the vinyl-based resin layer and the adhesive layer also showed good results in antibacterial and antifungal properties after 10 washing tests. In addition, no bloom is seen. On the other hand, in Comparative Example 1, the organic antibacterial and antifungal agent is contained only in the adhesive layer, and the antibacterial and antifungal property is insufficient. The same applies to the case where the organic antibacterial and antifungal agent of Comparative Example 2 is added only to the vinyl chloride resin layer. The addition of 4.0% of the inorganic antibacterial and antifungal agent of Comparative Example 3 also has an insufficient antibacterial and antifungal effect. This is probably because the antibacterial and antifungal agent did not migrate to the base fabric layer or was extremely slow because it was an inorganic type.
In Comparative Example 4, no antibacterial and antifungal agent was used, and naturally no antibacterial and antifungal property was observed.
