Abstract
Abstract An antibiotic resin composition comprises at least one antibiotic zeolite of which ion-exchangeable ions are partially or completely replaced with ammonium ionsand antibiotic metal ions, at least one discoloration inhibitor and at least one resin. The antibiotic resin composition exhibits excellent antibiotic property and does not discolor with time. Thus, the resin composition can be employed to form a variety of products which require antibacterial and/or antifungus properties.
