Document Type and Number:
Japanese Patent JP2016068267
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gass barrier film which is hardly broken even if bent or stretched and can maintain high barrier properties; and a method for producing the gass barrier film.SOLUTION: There are provided: a gas barrier film which comprises a substrate film, an easily adhesive layer, an organic layer and an inorganic layer in this order, in which the organic layer has an internal stress of 2.0 MPa or less, a glass transition temperature of 200°C or more and a thickness of 1.0 μm or more; and a method for producing the gass barrier film, which comprises: coating an organic layer-forming composition on the surface of the easily adhesive layer of the substrate film having an easily adhesive layer to obtain a coating film; drying the coating film; and after the drying, curing the organic layer-forming composition to form the organic layer, in which the organic layer-forming composition contains a solvent, the concentration of the solid content obtained by removing the solvent from the organic layer-forming composition is 1.0 to 4.5 mass% based on the total amount of the organic layer-forming composition and the drying time for the drying is 25 seconds or more.SELECTED DRAWING: Figure 1
