Abstract:
A process for producing a laminate, which comprises coating an adhesive containing a thermoplastic polyester resin component as the main component, on either one of a substrate or a tetrafluoroethylene-perfluoroalkoxyethylene copolymer film having its surface RF bombardment-treated, then drying the adhesive, and thereafter, bonding the substrate and the RF bombardment-treated tetrafluoroethylene-perfluoroalkoxyethylene copolymer film by the adhesive containing the thermoplastic polyester resin component as the main component, to form a laminate by a dry lamination method, wherein the amount of fluorine atoms removed from the treated surface of said copolymer film by an adhesive tape is not more than twice the amount of fluorine atoms removed from the surface of a non-surface-treated tetrafluoroethylene-perfluoroalkoxyethylene copolymer film.
