An embodiment relates to a lamination film, a light-transmitting laminate comprising same, and the like, and provides a lamination film comprising an area with increased thickness, wherein the area with increased thickness has two ends consisting of one end and the other end, the two ends have different thicknesses, an embossed surface is included, at least a part of the embossed surface is arranged on one surface of the area with increased thickness, the maximum of the glossiness of each of a first part and a second part of the embossed surface, which are measured at an acceptance angle of 20°, 45°, 60°, 75° and 85°, is 15% or less, and the Spd value of the embossed surface is 200 mm-2 or greater. The lamination film and the like control the characteristics of an embossed surface so as to control irregular reflection, which can occur in a wound state, and thus can provide excellent visibility during visual inspection.
Un mode de réalisation concerne un film de stratification, un stratifié transmettant la lumière le comprenant, et analogues, et fournit un film de stratification comprenant une zone ayant une épaisseur accrue, la zone ayant une épaisseur accrue ayant deux extrémités constituées d'une extrémité et de l'autre extrémité, les deux extrémités présentent des épaisseurs différentes, une surface gaufrée est incluse, au moins une partie de la surface gaufrée est disposée sur une surface de la zone avec une épaisseur accrue, le maximum de la brillance de chacune d'une première partie et d'une seconde partie de la surface gaufrée, qui sont mesurées à un angle d'acceptation de 20°, 45°, 60°, 75° et 85°, est de 15 % ou moins, et la valeur Spd de la surface gaufrée est de 200 mm-2 ou plus. Le film de stratification et analogues commande les caractéristiques d'une surface gaufrée de façon à commander une réflexion irrégulière, qui peut se produire dans un état enroulé, et peut ainsi fournir une excellente visibilité pendant une inspection visuelle.
구현예는 접합용 필름, 이를 포함하는 광투과 적층체 등에 대한 것으로, 두께 증가 영역을 포함하고, 상기 두께 증가 영역은 일단과 타단의 양 말단을 가지며, 상기 양 말단은 두께가 서로 다르고, 엠보가 형성된 면을 포함하며, 상기 엠보가 형성된 면의 적어도 일부는 상기 두께 증가 영역의 일면에 배치되고, 상기 엠보가 형성된 면의 제1부분 및 제2부분 각각에서, 수광각 20°, 45°, 60°, 75°, 및 85°에서 측정한 광택도 중 최대값이 15% 이하이며, 상기 엠보가 형성된 면의 Spd 값은 200 mm -2 이상인 접합용 필름을 제공한다. 상기 접합용 필름 등은 엠보가 형성된 면의 특성을 제어하여 권취 상태에서 발생할 수 있는 불규칙적인 반사현상을 조절하여 외관검사시 우수한 시인성을 가질 수 있다.
