Abstract
A resinous flooring sheet is obtained by laminating successively on a light-shielding resinous base sheet (1), a transparent synthetic resin intermediate layer (2), a light-shielding ink pattern (3) and an overcoat transparent synthetic resin layer (4). This flooring sheet can impart abundant three-dimensional or visual depth impression through the optical path difference between the reflected light from the light-shielding ink pattern (3) and the reflected light from the light-shielding synthetic resinous base sheet (1) as well as through the shading of the light-shielding pattern (3) projected through the transparent synthetic resin intermediate layer (2) on the light-shielding synthetic resinous base sheet (1).
