Abstract
(EN)
The present invention provides the following, etc., as resin compositions having excellent gas barrier properties, especially oxygen barrier properties, under high humidity conditions. A resin composition including a hydrophilic resin and a metallic compound, the resin composition being characterized by satisfying formula (1) when made into a film. (1): α - β ≥ 1, where α represents the average metal atom concentration (%) within a depth of 0-9 nm from the surface of the film, and β represents the average metal atom concentration (%) within a depth of 12-21 nm from the surface of the film.
(FR)
La présente invention concerne les éléments suivants, etc., en tant que compositions de résine présentant d'excellentes propriétés de barrière aux gaz, en particulier des propriétés de barrière à l'oxygène, dans des conditions d'humidité élevée. La présente invention concerne une composition de résine comprenant une résine hydrophile et un composé métallique, la composition de résine étant caractérisée en ce qu'elle satisfait à la formule (1) lorsqu'elle est transformée en un film. (1) : α - β ≥ 1, où α représente la concentration en atomes métalliques moyenne (%) à une profondeur de 0 à 9 nm de la surface du film, et β représente la concentration en atomes métalliques moyenne (%) à une profondeur de 12 à 21 nm de la surface du film.
(JA)
