An adhesive sheet which comprises a base (A) comprising a wholly aromatic polyimide film having a glass transition temperature of 200~C or higher and a thermal-adhesion layer (C) comprising a wholly aromatic polyamide having a glass transition temperature of 200 to 500~C and which has a specific peel strength or shearing peel strength; a layered product including the adhesive sheet; and a process for producing the layered product. Also provided is a method for obtaining a layered product including a desired treated layer, which comprises subjecting a layered product including the adhesive sheet to a treatment and then removing the sheet.

L'invention concerne une feuille adhésive composée d'une base (A), comportant un film polyimide entièrement aromatique dont la température de transition vitreuse est supérieure ou égale à 200 DEG C, et d'une couche thermoadhésive (C), comportant un film polyamide entièrement aromatique dont la température de transition vitreuse varie entre 200 DEG C et 500 DEG C, et dotée d'une résistance au pelage spécifique ou d'une résistance au pelage et au cisaillement. La présente invention porte également sur un produit en couches comportant une feuille adhésive et sur un procédé de production associé. Cette invention concerne aussi un procédé pour réaliser un produit en couches comprenant une couche traitée donnée, ce procédé consistant à soumettre ledit produit en couches doté de la feuille adhésive à un traitement avant d'enlever la feuille.
