Title
(EN) POLYVINYL ACETAL RESIN FILM AND MULTILAYER BODY CONTAINING SAME
(FR) FILM DE RÉSINE D'ACÉTAL DE POLYVINYLE ET CORPS MULTICOUCHE LE CONTENANT
(JA) ポリビニルアセタール樹脂フィルムおよびそれを含む積層体
Abstract
(EN)
The present invention relates to a polyvinyl acetal resin film which is composed of a polyvinyl acetal resin material, and which is configured such that: the relative diffuse reflectance of at least one surface at the wavelength of 550 nm is 3% or more; the absolute value of the difference between the relative diffuse reflectance of one surface at the wavelength of 550 nm and the relative diffuse reflectance of the other surface at the wavelength of 550 nm is 0.5% or more; and the amount of a plasticizer in the polyvinyl acetal resin film is 0-20% by mass based on the total mass of the polyvinyl acetal resin film.
(FR)
La présente invention concerne un film de résine d'acétal de polyvinyle qui est composé d'un matériau de résine d'acétal de polyvinyle, et qui est configuré de telle sorte que : la réflectance diffuse relative d'au moins une surface à la longueur d'onde de 550 nm est supérieure ou égale à 3 %; la valeur absolue de la différence entre la réflectance diffuse relative d'une surface à la longueur d'onde de 550 nm et la réflectance diffuse relative de l'autre surface à la longueur d'onde de 550 nm est de 0,5 % ou plus; et la quantité d'un plastifiant dans le film de résine d'acétal de polyvinyle est de 0 à 20 % en masse sur la base de la masse totale du film de résine d'acétal de polyvinyle.
