Abstract
A matte-like cured coating film of a curable resin composition is provided on a substrate such as a wiring board, in which scratches are unnoticeable. The cured coating film satisfies Gs (20°)≤5 and Gs (85°)≥35 and has a ratio R represented by the formula R={Gs (85°)/Gs (60°}/{Gs (60°)/Gs (20°)} ranging from 0.35 to 4.0, where Gs (20°), Gs (60°), and Gs (85°) are 20° gloss, 60° gloss, and 85° gloss on a surface of the cured coating film measured according to JIS Z 8741-1997, respectively.
