[0338] (1) Formation process of base layer

[0339] As a thermoplastic resin, 60 parts of polysulfone-based resin (PSF) pellets (manufactured by BASF Corporation, "ULTRASON S3010", Tg=180° C.) were dissolved in methylene chloride to prepare a 15% solution of PSF.

[0340] To this solution were added 40 parts of tricyclosilane dimethanol diacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd., ADCP) as an energy ray curable component, and bis(2,4,6-trimethylmethacrylate) as a polymerization initiator. 1 part of benzoyl)phenylphosphine oxide (manufactured by BASF, "Irgacure 819") was mixed to prepare a composition for a base layer.

[0341]As the first release sheet, apply by die coating on the non-treated surface of the easy-adhesive-treated polyethylene terephthalate (PET) film (manufactured by Toyobo Co., Ltd., "PET50A-4100", thickness 50 μm) The composition for the base layer prepared above was spread to form a coatin...

Abstract

The gas-barrier film according to the present invention comprises a layered product obtained by superposing a release sheet, an undercoat layer, a gas-barrier layer, and an adhesive layer in this order, wherein the adhesive layer is a layer formed from an adhesive composition comprising a polyolefin-based resin (A) and a thermally curable component (B).

Description

technical field [0001] The present invention relates to a gas barrier film and a sealed body obtained by sealing an object to be sealed with the gas barrier film. Background technique [0002] In recent years, organic EL elements have attracted attention as light-emitting elements capable of emitting light with high luminance by low-voltage DC driving. However, organic EL elements have a problem that light emission characteristics such as light emission luminance, light emission efficiency, and light emission uniformity tend to decrease over time. [0003] The problem of performance degradation over time represented by organic EL elements is a problem existing in electronic components and optical components as a whole that have attracted attention in recent years. The cause is considered to be that oxygen, moisture, and the like infiltrate into electronic components and optical components to cause performance degradation. [0004] Furthermore, as countermeasures against th...
