Problems to be Solved by the Invention The above-mentioned chemical method using a silver compound requires the use of an expensive silver compound, and therefore the manufacturing cost is inevitably high. Furthermore, it is necessary to remove metallic silver produced as a result of the reaction by excessive operations, which causes a decrease in productivity.
Furthermore, if even a small amount of silver is mixed into the product, the quality of the product as an infrared absorber will deteriorate, so special care must be taken to prevent metallic silver from being mixed into the product.
In addition, in the electrolytic method using a metal salt, metal precipitation occurs on the cathode, and a decrease in production efficiency cannot be avoided.

Electrolytic oxidation may be carried out at any current density, preferably 5 mA/cm 2 to 100 mA/cm 2 . The electrolysis temperature varies depending on the organic solvent used, but is 0 to 50℃.
It is preferable to do so. It is usually carried out at a temperature below the boiling point of the solvent used. The amount of electricity required for electrolytic oxidation may be the theoretical amount (1F/mol), but the reaction should be checked using thin layer chromatography or the like and adjusted as necessary. The electrolytic cell is preferably equipped with a stirring device to provide an appropriate flow of liquid in order to make the electrolytic system uniform during the electrolytic reaction. Hexafluoroantimonic acid is preferably used as a hexahydrate because it is readily available, but an aqueous solution may also be used. The amount used is 1 to 30 times the amount of the reaction substrate. In addition, perchloric acid is used in the form of a low concentration aqueous solution from the viewpoint of handling, and the amount used is 1 to 30 times the mole of the reaction substrate.
