ANTIBACTERIAL RESIN MULTI-LAYERED MOLDING

PROBLEM TO BE SOLVED: To keep good antibacterial properties to microorganisms for a long term even under bad conditions where water is frequency used by including at least an antibacterial outer layer, an antibacterial intermediate layer and further an inner layer. SOLUTION: This antibacterial resin multi-layered molding comprises an antibacterial outer layer 11, an antibacterial intermediate layer 12 and an inner layer 13. An antibacterial agent which is difficult to migrate is added to the antibacterial outer layer 11. In addition, an antibacterial agent which is likely to migrate is added to the antibacterial intermediate layer 12. The antibacterial resin multi-layered molding thus constituted prevents both blackening caused by growth of mold and slime caused by growth of bacteria by adding the antibacterial agent which is hard to migrate or substantially does not migrate in a resin and the antibacterial agent which is apt to migrate in the resin, while their effects can be kept for a long time even under bad conditions where water is frequency used.
