By the presence of condensed phosphate containing alkaline earth metal on the surface of the titanium dioxide fine particles, the condensed phosphate is firmly bound to the titanium dioxide fine particles, making it difficult to be released from the surface of the titanium dioxide fine particles in a medium such as a binder or a resin. The photofunctional particle which has a is obtained. By using the said particles, the powder and slurry which have the outstanding optical function and durability, dispersion stability, and hydrophilicity, the polymer composition using this, a coating agent, a photofunctional molded object, and an optical functional structure are obtained. |
