Abstract
A multilayer sheet including a transparent film with a total light transmittance of 85% or more in accordance with ISO 13468, a coating layer disposed on a first surface of the transparent film, and an elastic film disposed below a second surface of the transparent film is disclosed. The Martens hardness HM measured on a surface of the coating layer is 180 N/mm2 or more.
