Embodiment 1

[0271] Produced as Example 1 figure 1 (A) shows the gas barrier film 10a.

[0272]

[0273] As the substrate 12, a long-sized PET film (manufactured by TOYOBO CO., LTD., Cosmo shine A4100) having a width of 1000 mm, a thickness of 50 μm, and a length of 100 m was used.

[0274] On the unprimed surface side of this substrate 12, a release resin layer 20 was formed according to the following procedure.

[0275] As coating liquid A1 used as the peeling resin layer 20, the coating liquid of 10% of solid content concentration was prepared by dissolving COC resin (Mitsui Chemicals, Inc. APEL 6015T) using cyclohexane.

[0276] The coating solution A1 is filled in such as Figure 8 (A) The coating part 40 of the RtoR-based film-forming apparatus shown. The coating unit 40 used a die coater. Then, the substrate roll Ra in which the substrate 12 is wound into a roll is loaded at a predetermined position, and the substrate 12 is inserted along a predetermined conveyance path.

Embodiment 2

[0294]Furthermore, an organic protective layer 24 shown below was formed on the inorganic layer 16. In the same manner as in Example 1, the following figure 2 (A) shows the gas barrier film 10b.

[0295] Polyurethane backbone acrylic polymer (ACRIT 8BR930 manufactured by TAISEI FINECHEMICAL CO., LTD.), photopolymerization initiator (Irg184 manufactured by BASF JAPAN LTD.), silane coupling agent (Shin -KBM5103 manufactured by Etsu Chemical Co., Ltd.) and softener (BYRONU1400 manufactured by TOYOBO CO., LTD.) were weighed and dissolved in methyl ethyl ketone to prepare a coating solution with a solid content concentration of 15%. As the coating liquid C1 to be the organic protective layer 24 .

[0296] Fill the coating liquid C1 in such as Figure 8 (A) The coating part 40 of the RtoR-based film-forming apparatus shown. The coating unit 40 used a die coater. Then, a substrate roll in which the substrate 12 (hereinafter, sometimes referred to as "film-forming base material Z...

Embodiment 3

[0299] The following coating liquid C2 was used as the coating liquid for the organic protective layer 24, and the thickness of the organic protective layer 24 was set to 3 μm. , A separator (FILM BYNA BD manufactured by FUJIMORI KOGYO CO., LTD.) was attached as the protective film 26, and in the same manner as in Example 2, the following figure 2 (B) shows the gas barrier film 10c.

[0300] Curing agent L-45 (manufactured by Soken Chemical & Engineering Co., Ltd.) was added to SK DYNE NT21 (manufactured by Soken Chemical & Engineering Co., Ltd.) at a ratio of 100:2, and diluted with butyl acetate to prepare a solid content concentration of 15 % of coating solution C2.

[0301] The organic protective layer 24 is an acrylic adhesive.

Abstract

The present invention provides a thin gas barrier film that can be transferred and has high gas barrier properties after transfer, and a transfer method of the gas barrier film, and provides a wavelength conversion film and a band barrier film using the gas barrier film. Retardation films for air layers and organic EL laminates. The gas barrier film has: a substrate; a gas barrier layer provided on one surface of the substrate and having a combination of at least one inorganic layer and an organic layer forming a surface of the inorganic layer; and a peeling resin layer provided on the substrate and the barrier layer. Between the air layers, it is in close contact with the organic layer and is used for peeling off from the substrate.

Description

technical field [0001] The present invention relates to a gas barrier film, a transfer method of the gas barrier film, a wavelength conversion film using the gas barrier film, a retardation film with a gas barrier layer, and an organic EL laminate. Background technique [0002] In recent years, high gas barrier properties are required for devices such as organic EL devices (organic electroluminescence devices), solar cells, quantum dot films, display materials, and packaging materials such as infusion bags containing drugs that are degraded by moisture or oxygen. . [0003] Therefore, in order to impart the necessary gas barrier properties, a gas barrier film is attached to these components or sealed with a gas barrier film. [0004] In order to apply a gas barrier film to a field requiring high gas barrier properties, Patent Document 1 describes methods for improving gas barrier properties as follows: a structure using an inorganic layer as a gas barrier layer; a multilaye...
