Abstract: The present invention herein provides antibacterial zeolite particles whose ion-exchangeable ions have completely or partially been replaced with silver ions and zinc ions, wherein the ratio (A/B) of the silver ion concentration (A) to the zinc ion concentration (B) in the antibacterial zeolite particles increases in the direction along the depth of each zeolite particle. The antibacterial zeolite particles show excellent discoloration-resistant characteristics, while maintaining their excellent antibacterial activities. Accordingly, the antibacterial zeolite particles can suitably be applied to all sorts of products that are required to have antibacterial properties.

Abstract: The present invention herein provides antimicrobial zeolite which hardly causes any color change with the elapse of time even when it is incorporated into a resin to form an antimicrobial resin composition. The present invention thus relates to antimicrobial zeolite which comprises zeolite whose ion-exchangeable ions are partially or wholly replaced with hydrogen ions and silver ions; and an antimicrobial resin composition which comprises the foregoing antimicrobial zeolite in an amount ranging from 0.05 to 80% by mass.

Abstract: The present invention relates to antimicrobial zeolite which comprises zeolite wherein a hardly soluble zinc salt is formed within fine pores present therein and an antimicrobial composition which comprises the foregoing antimicrobial zeolite in an amount ranging from 0.05 to 80% by mass. The antimicrobial zeolite according to the present invention can widely be applied, without causing any color change, even to the goods which undergo color changes with the elapse of time when the conventional antimicrobial zeolite is added.
