Coated metal sheet, method for manufacturing same, and exterior building material
The coated metal plate pertaining to the present invention is a coated metal plate for exterior use, and has a metal plate and a top coating film disposed on the metal plate. The top coating film contains 0.01-15 vol % of porous particles as a gloss adjusting agent, and the coated metal plate satisfies the expressions below. In the expressions below, R is the number-average particle diameter (μm), D97.5 is the diameter (μm) of 97.5% of the particles, Ru is the upper limit particle diameter (μm), and T is the film thickness (μm) of the top coating film in the number particle size distribution of the gloss adjusting agent. D97.5/T≤0.7; Ru≤1.2T; R≥1.0; 3≤T≤20.
