PROBLEM TO BE SOLVED: To provide a method for adding antibacterial property to a resin molded article by a simple method and the molded article.SOLUTION: Predetermined amount of iodine is adhered to a resin molded article by sublimating iodine in a closed space with standing for a certain point in time and coexisting the resin molded article and iodine in the closed space. A molded article having antibacterial property without damaging commercial value by controlling existing time or temperature of the closed space, setting adhesion amount of the iodine at 5 to 40 μg/cm2 in terms of surface area or 50 to 400 ppm in terms of weight of the molded article to suppress coloring or odor of the molded article by iodine.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】樹脂成型品に簡便な方法で抗菌性を付与する方法並びに成型品を提供する。【解決手段】樹脂成型品とヨウ素を密閉空間に一定時間静置して併存させることでヨウ素を密閉空間に昇華させて所定量のヨウ素を樹脂成型品に付着させた。併存時間や密閉空間の温度を制御することでヨウ素の付着量を成型品の表面積換算で5~40μg/cm2にすることで、もしくは成型品の重量換算で50~400ppmにすることで成型品のヨウ素による着色や匂いを抑えて商品価値を損なわない抗菌性のある成型品が得られた。【選択図】なし
