Abstract: PURPOSE: To obtain an antibacterial resin composition excellent in transparency by mixing a transparent thermoplastic resin with a finely divided inorganic antibacterial and a lubricant in specified ratios. CONSTITUTION: This transparent antibacterial resin composition is prepared by mixing 100 pts.wt. transparent thermoplasatic resin (A) with 0.05-10 pts.wt. inorganic antibacterial (B) having a mean particle diameter of 1μm or below and 0.01-10 pts.wt. lubricant (C). Antibacterials which impart antibacterial properties to resins are largely classified into two organic and inorganic types. The latter is generally used because the former has drawbacks in heat resistance, durability and safety. However, there is a tendency for the transparency to be markedly deteriorated even in use where transparency is necessary due to the difference between the densities of an inorganic antibacterial and a resin, its low affinity for the resin, etc. By using antibacterial B, (e.g. antibacterials carrying silver/silver ions or copper/copper ions or other various metal/metal ion antibacterials), the composition can be used as a material which needs to prevent the outbreak and propagation of bacteria.
