Abstract

PROBLEM TO BE SOLVED: To obtain a fungicidal microbicide capable of stably imparting excellent fungicidal and antimicrobial properties to e.g. polymer molded products and synthetic fibers without reducing e.g. their transparencies, weather resistances and strengths by including a specific ethanolamine as a substance for providing fungicidal and antimicrobial properties. SOLUTION: This agent is obtained by including N-(2-hydroxydodecyl) ethanolamine and/or β-hydroxymyristyl-N-ethanolamine as a substance for providing fungicidal and antimicrobial properties. The usage is pref. 0.05 to 5 pts.wt. based on 100 pts.wt. of polymer component e.g. polystyrene resin. The agent is useful for producing e.g. outside layer materials safe and excellent in fungicidal and antimicrobial properties for packages, packaging films or household appliances.
