(JA) 化粧材
Abstract
(EN) A decorative material is provided which, not only when dry but even when wet with water, has excellent slip resistance and design properties. This decorative material, which has a picture layer, is characterized by having an irregular, uneven shape on one surface of the decorative material, and in that the uneven shape is such that the volume (Vvv+Vvc), represented by the total value of the void volume (Vvv) in a core part and the void volume (Vvc) in a valley part, measured by a 3D shape measurement device, is greater than or equal to 15 mL/m2.
(FR) L'invention concerne un matériau décoratif qui, non seulement lorsqu'il est sec mais même lorsqu'il est humidifié avec de l'eau, présente d'excellentes propriétés de résistance au glissement et de conception. Ce matériau décoratif, qui a une couche d'image, est caractérisé en ce qu'il présente une forme irrégulière sur une surface du matériau décoratif, et en ce que la forme irrégulière est telle que le volume (Vvv + Vvc), représenté par la valeur totale du volume de vide (Vvv) dans une partie de noyau et du volume de vide (Vvc) dans une partie de vallée, mesuré par un dispositif de mesure de forme 3D, est supérieur ou égal à 15 mL/m2.
(JA) 乾燥時だけでなく水濡れ時においても防滑性に優れ、意匠性にも優れた化粧材を提供する。 絵柄層を有する化粧材であって、上記化粧材の一方の面に不規則な凹凸形状を有し、上記凹凸形状は、3D形状測定機により測定した谷部の空隙容積(Vvv)とコア部の空隙容積(Vvc)との合計値で表される容積(Vvv+Vvc)が、15mL/m以上であることを特徴とする化粧材。
