GAS BARRIER MULTILAYER FILM

摘要

An inorganic oxide deposition layer and a gas barrier coating layer are sequentially formed on a base. The gas barrier coating layer is formed by applying a coating liquid onto the inorganic oxide deposition layer and drying it. The coating liquid contains a substance expressed by the general formula (1): Si(OR<1>)4 or a hydrolysate thereof, a substance expressed by the general formula (2): (R<2>Si(OR<3>)3)n or a hydrolysate thereof, (in the general formulae (1) and (2), R<1> and R<3> respectively represent CH3, C2H5, or C2H4OCH3, and R<2> represents an organic functional group), and a water-soluble polymer having a hydroxyl group.
