摘要：
The present invention relates to a coating composition containing metal oxide particles with a high refractive index and low photocatalytic activity and a coating film obtained by applying the coating composition onto a substrate. The coating composition contains metal oxide particles with a high refractive index obtained by coating the specific fine particles of the titanium-based oxide on their surfaces with at least a silica-based oxide or a silica-based composite oxide, and the coating film is obtained by applying the coating composition onto a substrate. The metal oxide particles with not only a high refractive index but also low photocatalytic activity, and therefore a coating film with excellent weathering resistance and light resistance can be formed on a substrate.
