Problems solved by technology

[0008] However, although such a film has improved the above-mentioned target properties to a certain extent, it is still not sufficient for, for example, the gas barrier properties of the laminated body, the lamination strength (adhesion between layers), especially when combined with the hygroscopic layer. In the field of organic devices that require extremely high gas barrier properties for bonding, it is desired to improve the above performance

[0086] The preparation method of the gas barrier laminated film for organic devices of the present invention has the following steps:

[0087] (1) The step of obtaining a gas barrier laminate having at least two inorganic thin film layers on at least one surface of the base material film, and the at least two inorganic thin film layers include a layer formed in contact with each other. more than two layers of inorganic thin film layers;

[0088] (2) A step of laminating a plurality of gas barrier laminates obtained above to obtain a gas barrier laminate film, wherein the surface of the base material film side of the gas barrier laminate to be laminated is It is opposite to the surface of the inorganic thin film layer of another gas barrier laminate, and an adhesive layer having a m-xylylenediamine skeleton is sandwiched between the gas barrier laminates. , p-xylylenediamine skeleton, and at least one epoxy-based adhesive in the bisphenol skeleton; and

Embodiment 1

[0122] Polyethylene terephthalate resin (hereinafter referred to as "PET"; "NOVAPEX" manufactured by Mitsubishi Chemical Co., Ltd.) was melt-extruded to form a sheet. direction, and then stretched in the width direction at a stretching temperature of 110° C. and a stretch ratio of 3.3 to obtain a biaxially oriented PET film with a thickness of 12 μm. On one side of the film, an isocyanate compound ("CORONET L" manufactured by Nippon Polyurethane Industry Co., Ltd.) and a saturated polyester ("Vylon 300" manufactured by Toyobo Co., Ltd., number average molecular weight 23000) were coated at a ratio of 1:1 by mass. The resulting mixture was mixed and dried to form an undercoat (AC) layer having a thickness of 100 nm.

[0123] Next, using a vacuum evaporation device, at 1.33 x 10 -3 Pa(1×10 -5 Under the vacuum of Torr), SiO is evaporated by high-frequency heating, and an inorganic thin film with a thickness of about 20 nm is formed on the undercoat layer.

Embodiment 2

[0128] A gas barrier film laminate was obtained and evaluated in the same manner as in Example 1, except that the order of producing the first and second inorganic thin films was reversed. The results are shown in Table 1.

Abstract

A gas barrier laminated film which has extremely excellent gas barrier properties and exerts excellent performance as an organic device, more specifically, a gas barrier laminated film obtained by laminating plural gas barrier laminates through one or more adhesive layers, wherein the gas barrier laminates each comprise a substrate film and at least two inorganic thin film layers lying on one side of the substrate film. The at least two inorganic thin film layers contain two or more inorganic thin film layers formed in contact with each other, while the laminating of the gas barrier laminates is conducted with the face of one gas barrier laminate on the substrate film side being opposite to the face of another gas barrier laminate on the inorganic thin film side. Further, each adhesive layer consists of an epoxy adhesive having at least one of m-xylenediamine skeleton, p-xylenediamine skeleton and bisphenol skeleton.

Description

technical field [0001] The present invention relates to a gas barrier multilayer film having excellent gas barrier properties and excellent performance when used as an organic device. Background technique [0002] For a long time, gas-barrier plastic films with plastic film as the base material and inorganic films such as silicon oxide, aluminum oxide, and magnesium oxide formed on the surface have been widely used in the packaging of items that need to isolate water vapor, oxygen, and other gases. Among them, such as packaging used to prevent deterioration of food, industrial supplies, and pharmaceuticals. In addition, the gas barrier plastic film has been used as a liquid crystal display element, a solar cell, an electromagnetic shielding material, a touch panel, an organic device, a color filter, a vacuum heat insulating material, etc. in addition to a packaging application in recent years. New uses for industrial components are also gaining attention. [0003] Regardin...
