Embodiment

[0368] Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited by the following examples.

[0369] Hereinafter, unless otherwise specified, "part" means "part by mass".

[0370] [Preparation of curable resin composition]

manufacture example 1）

[0371] (Manufacturing example 1) Preparation of curable resin composition 1

[0372] As the thermoplastic resin (A), 60 parts of pellets of polysulfone resin (PSF) (manufactured by BASF, ULTRASON S3010, Tg=180° C.) were dissolved in methylene chloride to prepare a 15% by mass solution of PSF. Next, 40 parts of tricyclodecane dimethanol diacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd., ADCP) as a curable monomer (B) and bis(2,4, One part of 6-trimethylbenzoyl)phenylphosphine oxide (Irgacure 819, manufactured by BASF) was mixed to prepare a curable resin composition 1 .

manufacture example 2～5）

[0373] (Production Examples 2 to 5) Preparation of Curable Resin Compositions 2 to 5

[0374] Curable resin compositions 2-5 were prepared by the method similar to the preparation method of curable resin composition 1 except having changed to the compounding ratio of Table 1.

Abstract

The present invention provides: a gas barrier film comprising a cured resin layer and a gas barrier layer, the gas barrier layer being provided on at least one side of the cured resin layer, the cured resin layer being a layer formed of a cured product of a curable resin composition that includes (A) a thermoplastic resin having a glass transition temperature (Tg) of 140°C or more, and (B) a curable monomer, the gas barrier film having a water vapor transmission rate of 1 g / m 2 / day or less at a temperature of 40°C and a relative humidity of 90%; a method for producing the gas barrier film; a gas barrier film laminate comprising the gas barrier film; an electronic device member comprising the gas barrier film; an electronic device member comprising the gas barrier film laminate; an electronic device comprising the electronic device member. Since the gas barrier film and the gas barrier film laminate of the present invention exhibits excellent heat resistance, excellent solvent resistance, excellent interlayer adhesion, and an excellent gas barrier capability, has a low birefringence, and exhibits excellent optical isotropy, the gas barrier film and the gas barrier film laminate may suitably be used as an electronic device member.

Description

technical field [0001] The present invention relates to a gas barrier film that can be preferably used as a member of an electronic device such as a liquid crystal display or an electroluminescence (EL) display, a method for producing the same, and a gas barrier film laminate obtained by laminating two or more of the gas barrier films , A component for an electronic device including the gas barrier film or a gas barrier film laminate, and an electronic device including the component for an electronic device. Background technique [0002] In recent years, in order to achieve thinner, lighter, and more flexible displays such as liquid crystal displays and electroluminescent (EL) displays, research has been conducted on using transparent plastic films instead of glass plates. [0003] However, plastic films generally transmit water vapor, oxygen, etc. compared to glass plates, so if a transparent plastic film is used as a substrate of a display, there is a problem that componen...
