Abstract
(EN)
The purpose of the present invention is to provide: a resin sheet that has a favorable feel and at least a prescribed optical transparency; and a molded article of the resin sheet. A resin sheet that has regularly arranged hair-like bodies on at least one surface of a base layer. The resin sheet forms a continuous phase in which there is no structural boundary between the base layer and the hair-like bodies. The average height of the hair-like bodies is 30–500 µm. The total light transmittance of the resin sheet as measured in accordance with JIS K 7136-1 is 0.1%–20%, and the contrast ratio of the resin sheet as measured in accordance with JIS K 5600 4-1 is 70%–98%.

Le but de la présente invention est de fournir : une feuille de résine qui a un toucher favorable et au moins une transparence optique prescrite ; et un article moulé de la feuille de résine. Une feuille de résine qui a des corps en forme de cheveux disposés de façon régulière sur au moins une surface d'une couche de base. La feuille de résine forme une phase continue dans laquelle il n'y a pas de limite structurelle entre la couche de base et les corps en forme de cheveux. La hauteur moyenne des corps en forme de cheveux est de 30 à 500 µm. La transmittance de lumière totale de la feuille de résine telle que mesurée selon JIS K 7136-1 est de 0,1 % à 20 %, et le rapport de contraste de la feuille de résine tel que mesuré selon JIS K 5600 4-1 est de 70 % à 98 %.
