The present invention has been completed by examining the function of barium sulfate doped with a specific amount of rare earth elements, and has excellent performance in terms of ultraviolet shielding, lubricity, adhesion, soft focus, and the like. Provide offer. A barium sulfate doped with a specific amount of a rare earth element, represented by the following general formula: (Ba X M 1-X ) SO 4 (M is a metal element, 0.5 ≦ X <1) Rare earth doped barium sulfate.
