| 摘要 |
The titanium oxide particulate product of the present invention is lightfast and overcomes the problems associated with conventional pigments. Broadly, the invention relates to pigments comprising or consisting essentially of titanium oxide particles, e.g., rutile and/or anatase, which have a surface coating comprising cerium radicals optionally combined with phosphorus radicals and an additional coating of zirconium oxide and/or aluminum oxide also optionally combined with phosphorus radicals. Such pigments can be used in many applications requiring lightfastness, e.g., coatings, plastics, paper laminates, synthetic textile fibers, cosmetics such as sun screen formulations, among many other applications.
