Abstract: front page image
(EN)Provided are a multilayered structure, an inner liner using the multilayered structure, and a pneumatic tire provided with the inner liner, said multilayered structure formed by active energy ray irradiation and comprising a total of 7 or more layers of A layers and B layers, wherein the A layer comprises a resin composition containing a gas-barrier resin, the B layer is adjacent to the A layer and comprises a resin composition containing an elastomer, the A layer has an average thickness of 0.001 μm to 10 μm inclusive per layer, and the B layer has an average thickness of 0.001 μm to 40 μm inclusive per layer.
(FR)L'invention porte sur une structure multicouche, sur un chemisage interne utilisant la structure multicouche et sur un pneu comportant le chemisage interne, laquelle structure multicouche est formée par irradiation de rayons d'énergie active et comprend un total de 7 couches ou davantage de couches A et de couches B, la couche A comprenant une composition de résine contenant une résine de barrière vis-à-vis des gaz, la couche B étant adjacente à la couche A et comprenant une composition de résine contenant un élastomère, la couche A ayant une épaisseur moyenne de 0,001 µm à 10 µm inclus par couche, et la couche B ayant une épaisseur moyenne de 0,001 µm à 40 µm inclus par couche.
(JA) ガスバリア樹脂を含む樹脂組成物からなるA層と、このA層に隣接し、エラストマーを含む樹脂組成物からなるB層とを有し、上記A層とB層が合計7層以上であり、上記A層の一層の平均厚みが0.001μm以上10μm以下、上記B層の一層の平均厚みが0.001μm以上40μm以下であり、活性エネルギー線が照射されてなる多層構造体この多層構造体を用いるインナーライナー及びこのインナーライナーを備える空気入りタイヤである。
