Abstract
(EN)
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.

La présente invention concerne une feuille décorative (1) de moulage comprenant : un matériau de base transparent stratiforme (10) ; un motif de projection (20) dont la hauteur n'est pas inférieure à 5 µm et qui est formé dans le matériau de base transparent stratiforme (10) lui-même ou qui est formé sur le matériau de base transparent stratiforme (10) à l'aide d'un autre élément transparent, dans une face (12) en regard de celle sur le côté de reconnaissance visuelle du matériau de base transparent stratiforme (10) ; une couche d'ajustement optique (30) transparente qui recouvre une face sur laquelle est disposé le motif de projection (20) et sur laquelle des renfoncements/saillies issus du motif de projection (20) sont formés sur la surface ; et une couche de coloration (40) qui recouvre la couche d'ajustement optique (30). Dans le matériau de base transparent stratiforme (10), l'élément transparent et la couche d'ajustement optique (30), la transmittance de la lumière totale dans une largeur de bande de lumière visible ayant une longueur d'onde de 400 à 800 nm n'est pas inférieure à 80 %. L'indice de réfraction de la couche d'ajustement optique (30) est supérieur d'au moins 0,03 à l'indice de réfraction de l'élément constituant le motif de projection (20). La couche d'ajustement optique (30) comporte une ou plusieurs premières couches d'ajustement optique ayant un indice de réfraction inférieur ou égal à 1,80.
