[0003] Such a conventional barrier laminate has the following problems. Transparent barrier laminates on which silicon oxide or aluminum oxide has been deposited have been widely used in recent years for their excellent transparency, air permeability resistance, and moisture permeability resistance, but have poor durability against repeated bending and have reduced barrier properties. There were issues such as the point to do. Among the polymer films, polyester films are frequently used, but have the above problems. Polyamide films, which are relatively flexible and durable, are also used as base films for transparent barrier laminates on which silicon oxide or aluminum oxide is deposited. There is a problem that the adhesive strength in the interfacial adhesiveness with a polyester film is significantly lower than that of a polyester film or the like, and particularly the adhesive strength in a state of moisture is small. Furthermore, in order to obtain a moisture-proof material that requires a high barrier property and transparency such as an image display material, it is difficult to obtain a barrier property only by providing a transparent inorganic oxide thin film such as silicon oxide or aluminum oxide on a transparent film. In many cases, the transparency is still insufficient.
