Abstract

The present invention relates to a multilayer structure including a base (X) and a layer (Y) stacked on the base (X). The layer (Y) contains an aluminum-containing compound (A), an organic phosphorus compound (BO), and a polymer (F) having an ether bond and having no glycosidic bond.

First claim

1 : A multilayer structure comprising a base (X) and a layer (Y) stacked on the base (X), wherein
the layer (Y) comprises an aluminum-containing compound (A), an organic phosphorus compound (BO), and a polymer (F) having an ether bond and having no glycosidic bond.

2 : The multilayer structure according to claim 1 , wherein the aluminum-containing compound (A) is a compound (Ab) comprising a reaction product (D) of an aluminum-containing metal oxide (Aa) and an inorganic phosphorus compound (BI).

3 : The multilayer structure according to claim 1 , wherein a weight ratio between the organic phosphorus compound (BO) and the polymer (F) is 30:70 to 99:1.

4 : The multilayer structure according claim 2 , wherein a ratio W BO /W BI between a weight W BI of an inorganic phosphorus compound (BI) and a weight W BO of the organic phosphorus compound (BO) satisfies a relationship of 0.01/99.99≦W BO /W BI <6.00/94.00.

5 : The multilayer structure according to claim 1 , wherein the organic phosphorus compound (BO) is a polymer having at least one functional group selected from the group consisting of a phosphoric acid group, a phosphorous acid group, a phosphonic acid group, a phosphonous acid group, a phosphinic acid group, and a phosphinous acid group.

6 : The multilayer structure according to claim 1 , wherein the polymer (F) is polyethylene glycol or polyethylene oxide.

7 : The multilayer structure according to claim 1 , wherein the base (X) comprises at least one layer selected from the group consisting of a thermoplastic resin film layer and a paper layer.

8 : A packaging material comprising the multilayer structure according to claim 1 .

9 : The packaging material according to claim 8 , further comprising a layer formed by extrusion coating lamination.

10 : The packaging material according to claim 8 , wherein the packaging material is a vertical form-fill-seal bag, a vacuum packaging bag, a pouch, a laminated tube container, an infusion bag, a paper container, a strip tape, a container lid, or an in-mold labeled container.

11 : A product comprising the packaging material according to claim 8 in at least a part of the product.

12 : The product according to claim 11 , wherein the product is adapted to function as a vacuum insulator, the product having an interior with a reduced pressure, the product comprising a substance contained in the interior, the substance being a core material.

13 : A protective sheet, comprising the multilayer structure according to claim 1 .

14 : The protective sheet according to claim 13 , wherein the protective sheet is suitable for protecting a surface of a photoelectric conversion device, information display device, or lighting device.

15 : An electronic device comprising the protective sheet according to claim 13 .
