PROBLEM TO BE SOLVED: To obtain an antimicrobial resin composition that contains a reaction product of an inorganic divalent-metal compound and polyhydroxy organic compound, as well as a silver-based inorganic antimicrobial agent, has excellent antifungal and antialgal properties and fabricability, and is useful for pipes, films, electric appliances, etc. SOLUTION: This antimicrobial resin composition comprises preferably 0.01-5 pts.wt. of a reaction product of (A) an inorganic compound of a divalent metal, such as zinc, and a polyhydroxy organic compound, such as ethylene glycol (to 100 pts.wt. of the antimicrobial resin composition), and preferably 0.01-10 pts.wt. of a silver-based inorganic antimicrobial agent (preferably in average particle size of 0.1-2μm), such as phosphate antimicrobial agent, of formula: Aga Ab M2 (PO4 )3 .nH2 O (A is an alkali (or alkaline earth) metal ion, ammonium ion or hydrogen ion; M is tetravalent metal ion; (n) is 0-6; a+mb=1, where (m) is the valence of A). Furthermore, it is preferable that this antimicrobial resin composition contains one or more metal oxides selected from zinc oxide and titanium dioxide. |
