Abstract

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).

Claim 1
Independent Claim 67 words
A resinous flooring sheet, which comprises a transparent synthetic resin intermediate layer laminated on the surface of a light-shielding resinous base sheet, a light-shielding pattern formed by application of a light-shielding ink provided on the surface of said transparent synthetic resin intermediate layer and an overcoat transparent synthetic resin layer laminated on the entire outer surface including said transparent synthetic resin intermediate layer and said light-shielding pattern.
Claim 2
Dependent Claim 67 words
A resinous flooring sheet, which comprises a transparent synthetic resin intermediate layer laminated on the surface of a light-shielding resinous base sheet, a light-shielding pattern formed by application of a light-shielding ink provided on the surface of said transparent synthetic resin intermediate layer and an overcoat transparent synthetic resin layer laminated on the entire outer surface including said transparent synthetic resin intermediate layer and said light-shielding pattern.
Claim 3
Dependent Claim 30 words
A resinous flooring sheet according to Claim 1, wherein the light-shielding resinous base sheet and/or the light-shielding pattern are/is colored with a colorant principally composed of a white light-shielding pigment.
