虫剤が多く、家庭内でも広く使用されるようになった。2. Description of the Related Art As a method for controlling pests, the most common method is application of a pesticide. However, there is a problem in the safety of drugs used as insect repellents. In recent years, studies have been conducted on the efficacy and toxicity of this component so as to improve the pest control effect and reduce the harm of this drug as much as possible, and considerable results have been seen. At the beginning of the development of insect repellents, the insecticidal effect was prioritized, so that many insect repellents based on phosphorus compounds were used widely at home.

た。However, as the use of these insect repellents has spread, their harmfulness has been pointed out, and there has been a demand for low-toxic insect repellents. The combination test reduced the amount of insect repellent used and increased safety. In addition, in the method of using these insect repellents, a method of adding the molten resin to the surface of a resin molded article has been used.

た。[0004] Since thermoplastic resins are easy to process, their application range is very large as fibers, cotton, films, sheets and other various molded products. In particular, textile products include beddings such as clothes, futons, blankets, sheets, curtains,
In addition to rugs such as upholstery, carpets and tatami mats, they are also used in large amounts as synthetic cotton and cushioning materials. By subjecting these molded products to processing that repels pests such as cockroaches, mites, fleas, and mosquitoes, it is possible to suppress the propagation of pests and prevent damage to pathogenic bacteria. Conventionally, the surface treatment of these resin molded products has been common, but the processed insect repellent is kneaded directly into the resin due to the reduced efficacy due to oxidation, ultraviolet rays, etc., or the falling off of the drug during use. The method began to take place.

In particular, when the melting temperature is 200 ° C. or higher, the temperature is easily affected.

There are many things. Among these organic compounds, among the aliphatic and aromatic organic acid ester derivatives having excellent heat stability and insect repellency, compounds having insect repellency have been found.
