[0003] However, in general, compared with glass plates, plastic films are more likely to transmit water vapor, oxygen, etc., and if a transparent plastic film is used as a substrate for a display, there will be water vapor, oxygen, etc. that pass through the substrate to act on the display surface. Problems such as performance degradation or shortened life of the equipment caused by components inside the equipment, etc.

preparation example Construction

[0155] The solvent used in the preparation of the above-mentioned curable resin composition is not particularly limited, and examples include: aliphatic hydrocarbon solvents such as n-hexane and n-heptane; aromatic hydrocarbon solvents such as toluene and xylene; dichloromethane , vinyl chloride, chloroform, carbon tetrachloride, 1,2-dichloroethane, monochlorobenzene and other halogenated hydrocarbon solvents; methanol, ethanol, propanol, butanol, propylene glycol monomethyl ether and other alcohol solvents; acetone , methyl ethyl ketone, 2-pentanone, isophorone, cyclohexanone and other ketone solvents; ethyl acetate, butyl acetate and other ester solvents; ethyl cellosolve and other cellosolve solvents; 1,3-di Ether solvents such as oxolane; etc.

[0156] Although content of the solvent in the said curable resin composition is not specifically limited, It is 0.1-1,000g normally with respect to 1g of polymer components (A), Preferably it is 1-100g. By appropriately adjusting ...

Embodiment 1

[0332] Curable resin composition 1 to be a base layer was prepared in the following procedure.

[0333]

[0334] As a polymer component, 100 parts by mass of polyimide resin (PI) pellets (manufactured by Kawamura Sangyo Co., Ltd., product name KPI-MX300F, Tg=354°C, weight average molecular weight: 280,000) were dissolved in methyl ethyl ketone (MEK) , a 15% by mass solution of PI was prepared. Next, 122 parts by mass of tricyclodecane dimethanol diacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd., A-DCP) as a curable monomer and bis(2 , 5 parts by mass of 4,6-trimethylbenzoyl)phenylphosphine oxide (manufactured by BASF Corporation, Irgacure 819), and curable resin composition 1 was prepared. In addition, the curable monomer and polymerization initiator used in this Example and other experimental examples do not contain a solvent, and all are raw materials whose solid content is 100%.

[0335] Next, use the first PET film (manufactured by Toyobo Co., Ltd.,...

Abstract

Provided is a gas barrier laminate which, even when produced by a coating method, has a reduced thickness and has excellent optical isotropy and gas barrier properties, and can appropriately be used as a member for an electronic device. The gas barrier laminate is provided with a process film, a base layer, and a gas barrier layer, in this order, wherein the base layer is a layer comprising a cured product of a curable resin composition containing a polymer component (A) and a curable monomer (B), and the glass transition temperature of the polymer component (A) is 250 DEG C or higher.

Description

technical field [0001] The present invention relates to a gas barrier laminate preferably used as a member for electronic devices such as liquid crystal displays and electroluminescent (EL) displays. Background technique [0002] For displays such as liquid crystal displays and electroluminescence (EL) displays, use of transparent plastic films instead of glass plates has been considered in order to achieve thinner, lighter, and more flexible displays. [0003] However, in general, compared with glass plates, plastic films are more likely to transmit water vapor, oxygen, etc., and if a transparent plastic film is used as a substrate for a display, there will be water vapor, oxygen, etc. that pass through the substrate to act on the display surface. Components inside the device, etc., may lead to problems such as reduced performance or shortened life of the device. [0004] In order to solve this problem, it has been proposed to use a film having a property of suppressing pe...
