Title:
GAS BARRIER FILM
Document Type and Number:
WIPO Patent Application WO/2017/013980
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a gas barrier film that has excellent gas barrier properties and exceptional durability in high-temperature and high-humidity environments, specifically in terms of having exceptional adhesion between a gas barrier layer and a base material even when subjected to a high-temperature and high-humidity environment. This gas barrier film is characterized by including a laminate C in which a foundation layer A that contains a compound including a transition metal M1 and a gas barrier layer B that contains at least silicon (Si) and nitrogen (N) and that is formed in contact with the foundation layer A are laminated in the stated order, and is characterized in that when the thickness-direction composition of the laminate C is analyzed by XPS, the transition metal M1 and Si are present together in the interface region between the foundation layer A and the gas barrier layer B, a region D is present in which the value of the atomic ratio of the transition metal M1/Si is within the range of 0.11-9.0, and the thickness of the region D is at least 5 nm.
