ABSTRACT:
As an ultraviolet absorbent material, ceric oxide sol which can be widely used in many fields using various solvent materials is obtained.
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.
This sol may widely be used in utilities using various organic solvent materials, such as paint materials.
