Abstract

A precoated steel sheet including a photocatalyst layer (coating film) as the outermost layer is provided in which a decrease in aesthetic appearance caused by processing unevenness or interference color streaks is prevented by forming the photocatalyst layer as a discontinuous (network) layer. The precoated steel sheet has performances required of precoated steel sheets, such as appearance evenness and processability, and further has various excellent properties such as a high degree of weatherability, durability of the aesthetic appearance, and resistance to decomposition with the photocatalyst. Also provided is a process for producing the precoated steel sheet. The precoated steel sheet comprises a steel sheet base, a clear coating layer (A) formed over at least one surface of the base, the layer (A) comprising a silicon compound as a main component and containing water-repellent fine particles dispersed therein, and a clear coating layer (B) superposed on the clear coating layer (A), the layer (B) containing, as a main component, fine titanium oxide particles which show photocatalytic activity.
