Abstract:
1. A process for producing a laminate comprising a substrate sheet containing an ethylene/tetrafluoroethylene copolymer, an adhesive layer, and a moisture-proof layer containing at least 95 mol % of at least one inorganic compound selected from the group consisting of an inorganic oxide, an inorganic nitride and an inorganic oxynitride, laminated in this order, wherein the adhesive layer contains at least 95 mol % of at least one metal oxide selected from the group consisting of zirconium oxide, tantalum oxide and hafnium oxide, and wherein the thickness of the moisture-proof layer is at most 50 nm, said process comprising; forming the adhesive layer on at least one side of the substrate sheet by a sputtering method in the presence of oxygen and argon, and forming the moisture-proof layer on the adhesive layer by a dry method.
