Title:
光機能性粉体及びその用途
Document Type and Number:
Japanese Patent JP4233324
Kind Code:
B2
Abstract:
A condensed phosphate containing an alkaline earth metal is caused to be present on the surface of titanium dioxide fine particles and, as a result, the condensed phosphate is firmly coupled with the fine particles and is barely liberated from the surface of the fine particles into a medium such as a binder or a resin. As a result, photo-functional particles exhibiting durability and dispersion stability are obtained. By use of the photo-functional particles, a powder and a slurry exhibiting excellent photo-functional properties, durability, dispersion stability, and hydrophilicity are produced. In addition, by use of the powder and slurry, a polymer composition, a coating agent, a photo-functional formed article, and a photo-functional structure can be produced.
