WIPO Patent Application WO/2020/138101

A1

A molding decorative sheet (1) according to the present invention is provided with: a sheet-like transparent base material (10); a projection pattern (20) that has a height of not less than 5 µm and that is formed in the sheet-like transparent base material (10) itself or is formed on the sheet-like transparent base material (10) by using another transparent member, in a face (12) opposite to that on the visual recognition side of the sheet-like transparent base material (10); a transparent optical adjustment layer (30) which covers a face having the projection pattern (20) disposed thereon and on which recesses/projections derived from the projection pattern (20) are formed on the surface; and a coloring layer (40) that covers the optical adjustment layer (30). In each of the sheet-like transparent base material (10), the transparent member, and the optical adjustment layer (30), the transmittance of total light in a bandwidth of visible light having a wavelength of 400-800 nm is not less than 80%. The refractive index of the optical adjustment layer (30) is greater by at least 0.03 than the refractive index of the member constituting the projection pattern (20). The optical adjustment layer (30) has one or more first optical adjustment layers having a refractive index of not more than 1.80.
