As an ultraviolet absorbent material, ceric oxide sol which can be widely used in many fields using various solvent materials is obtained. n An anionic aqueous sol is obtained by adding phosphoric acid and/or phosphate to cationic ceric oxide sol. It is a sol that can be applied to an emulsion paint. By further adding a cationic surface active agent to this sol, an organo-ceric oxide sol that can be applied to various organic solvents is formed. n This sol may widely be used in utilities using various organic solvent materials, such as paint materials. |
