The product obtained from the product or the coated product significantly impairs the design. In addition, because silver ions are supported on the powder, the dispersibility in the resin and paint is poor, and because the active ingredient is hidden inside the resin product and the coating film, the antibacterial and antifungal properties are fully exhibited. There were problems such as not being done.
