Although vinyl chloride resin itself has flame retardancy, depending on the requirements of the structure of the electric wire and cable and the application in which it is used, further flame retardants such as antimony trioxide may be blended to achieve a high level of flame retardancy that meets the requirements. It is necessary to have sex. However, since these flame retardants are opaque, it is difficult to achieve both flame retardancy and transparency. It is possible to achieve both flame retardancy and transparency by using a general phosphate ester flame retardant, but in this case, there is a unique odor of phosphate ester, and the space where people live such as offices and homes There was a problem with the use in the.

透明性の低下を招き本発明の目的を達成できない。The antimony pentoxide used in the present invention imparts flame retardancy while maintaining transparency. Since antimony pentoxide alone significantly reduces the thermal stability of the composition, an alkali metal compound, a perchloric acid compound, a hydrophobic amine compound, a higher fatty acid ester, a higher fatty acid ester amide, and an ether-based nonionic surfactant are used in advance. One having at least one compound selected from the phosphoric acid esters thereof and having improved thermal stability is used. The amount of antimony pentoxide added is 1 to 15 parts by weight. If the amount is less than 1 part by weight, sufficient flame retardancy cannot be imparted. If the amount exceeds 15 parts by weight, the transparency is reduced, and the object of the present invention cannot be achieved.
