Abstract
Provided by the present invention is a photocatalytic coating composition which can express excellent visibility during application work and further can, owing to its excellent physical properties, form a homogeneous photocatalyst coated film having uniform thickness on a surface of a substrate. The photocatalytic coating composition which is basic and comprises photocatalyst particles, a basic dye, a layered silicate, and a dispersion medium. The basic dye enhances visibility of the part where the photocatalytic coating composition is applied so that the applied part can be easily distinguished from the unapplied part by the difference in appearance. After application work, color of the basic dye disappears by photolysis with a solar light or by decomposition with a photocatalyst. The layered silicate suppresses color change of the basic dye over time and stably keep color tone of the same.
