Title
(EN) MULTILAYER FILM, METHOD FOR PRODUCING SAME AND ROLL
(FR) FILM MULTICOUCHE, SON PROCÉDÉ DE PRODUCTION ET ROULEAU
(JA) 複層フィルム及びその製造方法、並びに巻回体
Abstract
(EN)
A long multilayer film which is provided with: a resin layer S1 that is formed of a resin s1 containing an alicyclic structure-containing polymer and particles; and a resin layer C that is formed of a resin c containing an alicyclic structure-containing polymer. The average particle diameter and the amount of the particles are within specific ranges; the resin c does not contain particles, or contains a specific amount of particles; the resin c does not contain an ultraviolet absorbent, or contains a specific amount of an ultraviolet absorbent; and a surface of the resin layer S1, said surface being on the reverse side from the resin layer C, has a roughness parameter satisfying a specific requirement.
(FR)
L'invention concerne un long film multicouche comportant : une couche de résine S1 qui est formée d'une résine s1 contenant un polymère contenant une structure alicyclique et des particules ; et une couche de résine C qui est formée d'une résine c contenant un polymère contenant une structure alicyclique. Le diamètre moyen des particules et la quantité de particules se situent dans des plages spécifiques ; la résine c ne contient pas de particules, ou contient une quantité spécifique de particules ; la résine c ne contient pas d'absorbant d'ultraviolets, ou contient une quantité spécifique d'un absorbant d'ultraviolets ; et une surface de la couche de résine S1, ladite surface étant située sur la face opposée à la couche de résine C, présente un paramètre de rugosité conforme à une exigence spécifique.
(JA)
脂環式構造含有重合体及び粒子を含む樹脂s1で形成された樹脂層S1と、脂環式構造含有重合体を含む樹脂cで形成された樹脂層Cと、を備える、長尺の複層フィルムであって、粒子の平均粒子径及び量が特定範囲にあり、樹脂cが粒子を含まないか特定量含み、樹脂cが紫外線吸収剤を含まないか特定量含み、且つ、樹脂層S1の樹脂層Cとは反対側の面が特定の要件を満たす粗さパラメータを有する。
