摘要： The present invention provides a release film which has a release layer on a film substrate, which has excellent long-term preservation stability and yet maintains a stripping performance of the release film, which serves to make inspection for foreign materials easy, and which provides excellent design effect when a print layer is formed. The release film has average luminous reflectance of the release film on the surface of the side on which the release layer is formed being in the range of 0.5-2.5%, spectral reflectance curve of the release film surface on which the release layer is formed having a local minimal value and no local maximal value in the wavelength region in the range of 400-800 nm, reflection hue of the release film on the side on which the release layer is formed satisfying both −8≦a*≦8 and −16≦b*≦8 in the L*a*b* color coordinate system.
