Title:
METHOD OF PRODUCING ANTIMICROBIAL METAL ARTICLES AND ANTIMICROBIAL METAL ARTICLES PRODUCED BY THE METHOD
Document Type and Number:
WIPO Patent Application WO/1999/025898
Kind Code:
A1
Abstract:
A method of producing antimicrobial metal articles capable of imparting excellent antimicrobial property to the metal articles by the simple operations of applying a fine particle dispersion liquid or solution of antimicrobial components to the surface of the metal articles and pressurizing or rubbing the coated surface under a non-heating condition. Because these processing steps can be conducted by conventional rolling steps without changing them at all, the method is extremely advantageous economically. Because the antimicrobial metal article of this invention can be obtained under the non-heating condition, degradation of the antimicrobial components does not occur. Further, because the antimicrobial property does not disappear due to wear, etc., the excellent antimicrobial property can be maintained for a long time and moreover, the surface properties of the metal article such as the color tone does not change.
