防黴剤の出現が強く望まれていた。Many antibacterial and antifungal agents (phenolic compounds, organic halogen compounds, organic tin compounds, naphthenic acid compounds, organic compounds such as tar compounds) are used for the purpose of suppressing the growth of fungi for rubber. However, it is not possible to use substances that change the vulcanization conditions of rubber or change the physicochemical properties and electrical properties by adding antibacterial and antifungal agents, and direct contact It is not possible to use antibacterial and antifungal agents that cause toxicity to the human body. From this point, the emergence of an appropriate antibacterial and antifungal agent has been strongly desired.

Further, even a solvent such as water which does not directly dissolve the active ingredient compound can be used as long as it can disperse or dissolve the active ingredient compound with an auxiliary agent such as a surfactant. Examples of applicable organic solvents include benzene, xylene, toluene, kerosene, alcohols, ketones, dimethylsulfoxide, and dimethylformamide. A suitable surfactant and other auxiliary agents such as a spreading agent and a fixing agent are mixed with this and used as an aqueous solvent or an emulsion. For example, in the case of using an emulsion containing 50 to 60% of the active ingredient, a method of diluting it with water 600 to 1000 times and spraying it on the rubber is exemplified.
