Title
(EN) FILM AND METHOD OF PRODUCING THE SAME
(FR) FILM ET PROCÉDÉ DE PRODUCTION D’UN TEL FILM
Abstract
(EN) Provided is a film that has high-quality low gloss appearance with a small change in appearance of texture as observed at various viewing angles and that has tactile texture. Solution means A film of an embodiment is a film including a surface layer embossed, wherein the surface layer includes a low gloss layer and a gloss printed pattern partially covering the low gloss layer, (1) 85-degree surface glossiness of the surface layer is less than or equal to 3.5 GU as an in-plane average value; (2) Δ85-degree surface glossiness defined by a difference between an in-plane maximum value of the 85-degree surface glossiness and the in-plane average value of the 85-degree surface glossiness of the surface layer (= in-plane maximum value of 85-degree surface glossiness - in-plane average value of 85-degree surface glossiness) is from 0.2 to 2.5, and (3) surface roughness Ra of an embossed surface of the film is greater than or equal to 3.5 µm.
(FR) L'invention concerne un film qui présente un aspect de haute qualité à faible brillance et une légère variation d'aspect de texture, tel qu'observé sous divers angles d'observation et qui possède une texture tactile. Un film selon un mode de réalisation est un film comprenant une couche superficielle gaufrée, la couche superficielle comprenant une couche à faible brillance et un motif imprimé brillant recouvrant partiellement la couche à faible brillance, (1) une brillance superficielle à 85 degrés de la couche superficielle est inférieure ou égale à 3,5 GU en valeur moyenne dans le plan ; (2) une brillance superficielle à Δ85 degrés définie par une différence entre une valeur maximale dans le plan de la brillance superficielle à 85 degrés et la valeur moyenne dans le plan de la brillance superficielle à 85 degrés de la couche superficielle (= valeur maximale dans le plan de brillance superficielle à 85 degrés – valeur moyenne dans le plan de brillance superficielle à 85 degrés) est de 0,2 à 2,5, et (3) une rugosité superficielle Ra d'une surface gaufrée du film est supérieure ou égale à 3,5 µm.
