Abstract

Dans certains cas où un film de revêtement, qui est formé à partir d'une composition qui contient un composé ayant une structure perfluoropolyéther, est stratifié sur un substrat avec une autre couche interposée entre eux, le stratifié ainsi obtenu est exposé à un produit chimique tel qu'un alcool en fonction de son utilisation prévue; et dans ces cas, le stratifié est nécessaire pour conserver de bonnes propriétés même après l'exposition au produit chimique. Par conséquent, l'objectif de la présente invention est de fournir un stratifié présentant une excellente résistance chimique, tout en étant obtenu par stratification d'une couche, qui est formé à partir d'une composition contenant un composé ayant une structure perfluoropolyéther, sur un substrat avec une autre couche interposée entre eux. L'invention concerne un stratifié dans lequel une couche hydrofuge (r) et une couche de substrat de résine (s) sont stratifiées avec une couche (c) interposée entre elles, ladite couche (c) étant formée à partir d'une composition qui contient un composé organosilicié (C) qui a un atome de silicium qui est lié à un groupe hydrolysable, et qui a un groupe aminé ou un squelette amine. Ce stratifié est configuré de telle sorte que la couche hydrofuge (r) est formée d'une composition qui contient un composé organosilicié (A) représenté par la formule (a1).
