Abstract: front page image
(EN)Disclosed is an anti-glare multilayer body having anti-glare properties which realizes excellent dazzle prevention and black reproduction (presentation of black tone at low luminance levels). Specifically disclosed is an optical multilayer body comprising a light-transmitting base and an anti-glare layer formed on the light-transmitting base. The outermost surface of the anti-glare layer has recesses and projections, and the average distance S calculated by measuring the roughness curve of the recesses and projections of the anti-glare layer is not less than 0.04 mm but not more than 0.30 mm.
(FR)La présente invention concerne un corps optique multicouche ayant des propriétés antireflet qui assure une excellente protection contre l’aveuglement et une reproduction de corps noir (affichage de ton noir à des niveaux de luminosité faibles). L’invention concerne en particulier un corps optique multicouche qui comprend une base de transmission de la lumière et une couche antireflet formée sur ladite base. La surface le plus à l’extérieur de la couche antireflet présente des creux et des saillies, et la distance moyenne S calculée en mesurant la rugosité moyenne des creux et des saillies de ladite couche n’est pas inférieure à 0,04 mm ni supérieure à 0,30 mm.
(JA) 本発明は、防眩性を持ちつつ、優れたギラツキ防止性と黒色再現性(低輝度での黒色の階調表現)を実現できる防眩性積層体を開示する。本発明は、光透過性基材と、該光透過性基材上に防眩層を備えてなる光学積層体であって、前記防眩層の最表面が凹凸形状を有してなり、前記防眩層の凹凸形状の粗さ曲線を測定し算出された平均間隔Sが、0.04mm以上0.30mm以下であるものである。
