2. Description of the Related Art Conventionally, as industrial antifungal agents, mainly inorganic or organic compounds of heavy metals such as mercury, tin and copper and halogenated phenols have been used.
Since these compounds have high human toxicity and fish toxicity, they significantly deteriorate the working environment and living environment, and their use is greatly restricted. In general, wood, pulp, paint,
Industrial products such as sizing agents, skin repellents, textiles, and plastics often have the problem that mold grows and propagates, degrading the product value. In order to solve such a problem, antifungal agents have been proposed. A quaternary ammonium salt (hereinafter abbreviated as QAC) is known as a relatively excellent low-toxicity antifungal agent. However, in the case of this antifungal agent, there is a problem in that the antifungal effect is not sufficient and the durability of the antifungal effect is lacking because the antifungal effect is limited to specific types of fungi. In addition, as other fungicides, 2,3
Although 5,6-tetrachloro-4- (methylsulfonyl) pinidine (hereinafter abbreviated as TCMP) is known, this compound is effective against a wide range of molds, but has a problem that the fungicidal effect is weak at its practical concentration. was there.
