Abstract
(EN)
Disclosed is a film material for the interlayer films of laminated glasses which comprises resin layers for the interlayer film that comprise a first resin layer, which comprises one or more thermoplastic resins including a poly(vinyl acetal) resin and may further contain a plasticizer, and a second resin layer (additional resin layer), which has penetration resistance or sound-insulating properties or both of these functions. The content of the plasticizer in the first resin layer is 0-22 mass% with respect to the amount of the poly(vinyl acetal) resin.
(FR)
L'invention concerne un matériau de film pour les films intermédiaires pour verres feuilletés qui comprend des couches de résine pour le film intermédiaire comportant une première couche de résine, qui comprend une ou plusieurs résines thermoplastiques comprenant une résine de poly(acétal de vinyle) et qui peut en outre contenir un plastifiant, et une seconde couche de résine (couche de résine supplémentaire), qui présente une résistance à la pénétration ou des propriétés d'isolation phonique ou les deux. La teneur en plastifiant de la première couche de résine varie de 0 à 22 % en masse par rapport à la quantité de résine de poly(acétal de vinyle).
(JA)
ポリビニルアセタール樹脂を含む熱可塑性樹脂を含有し、可塑剤を更に含有していてもよい、第1の樹脂層と、耐貫通性、遮音性又はこれらの両方の機能を有する第2の樹脂層(追加の樹脂層)と、を有する中間膜用樹脂層を備える、合わせガラスの中間膜用フィルム材が開示される。第1の樹脂層における可塑剤の含有量が、ポリビニルアセタール樹脂の量を基準として0~22質量%である。
