1. A cured coating film, obtained from a curable photosensitive resin composition comprising at least an alkali-soluble resin, a photopolymerizable monomer, and a photoinitiator and formed on a substrate,
wherein the cured coating film has Gs (20°)≤5, Gs (85°)≥35, and a ratio R represented by formula R={Gs (85°)/Gs (60°)}/{Gs (60°)/Gs (20°)} being 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 said cured coating film measured according to JIS Z 8741-1997, respectively.
