[0083] (2) Preparation method of coating material for gas barrier
[0084] (3) Method, temperature and time of heat treatment of coating material for gas barrier
[0085] Hereinafter, an example of the method for producing the gas-barrier polymer layer 103 according to the present embodiment will be described.
[0086] First, (1) The compounding ratio of a polyhydric carboxylic acid and a polyamine compound is demonstrated.
[0087] (Compounding ratio of polycarboxylic acid and polyamine compound)
[0088] In this embodiment, (the number of moles of -COO- groups contained in the polyvalent carboxylic acid in the coating material for gas barrier) / (the number of moles of amino groups contained in the polyamine compound in the coating material for gas barrier) is preferably It is 100 / (more than 22), more preferably 100 / (25 or more), particularly preferably 100 / (29 or more).
[0089]On the other hand, in the present embodiment, (the number of moles of -COO- groups contained in ...
Embodiment
[0226] Hereinafter, this embodiment will be described in detail with reference to Examples and Comparative Examples. It should be noted that this embodiment is not limited by the description of these examples.
[0227]
[0228] Using a fluorescent X-ray analyzer (manufactured by Rigaku: ZSX PrimusII), A1 Kα rays in the aluminum oxide film obtained on the film substrate were measured, and the fluorescent X-ray intensity (A) kcps of the aluminum oxide film was measured. In addition, the fluorescent X-ray intensity (B) kcps of an aluminum film formed of aluminum and obtained on a film substrate under the same production conditions as the above-mentioned aluminum oxide film was measured except that oxygen was not introduced. The adhesion rate (A / B) was calculated from the obtained value.

[0230] Purified water was added to a mixture of ammonium polyacrylate (manufactured by Toagosei Co., Ltd., product name: Aron A-30, 30% by mass aqueous solution, molecular weight: ...
Embodiment 1
[0247] 79 g of the aforementioned ammonium polyacrylate aqueous solution (Z) and 21 g of the aforementioned polyethyleneimine aqueous solution (Y) were mixed and stirred to prepare a mixed liquid.
[0248] Furthermore, purified water was added so that the solid content concentration of the above mixed solution became 1.0% by mass, stirred until it became a uniform solution, and then the nonionic surfactant was mixed so that it became 0.3% by mass relative to the solid content of the mixed solution. agent (polyoxyethylene lauryl ether, manufactured by Kao Corporation, trade name: EMULGEN 120), and a solution (V) was prepared.
[0249] Using an applicator, apply the obtained solution (V) on the vapor-deposition surface of the alumina vapor-deposited PET film obtained in Comparative Example 1 so that the thickness after drying becomes 0.10 μm. Drying was performed at 100° C. for 30 seconds, and heat treatment was further performed at 200° C. for 15 minutes to obtain an amide cros...
