Abstract

The present invention is: a curable composition for forming a primer layer of a gas barrier laminated film, comprising at least a polar group-containing polyolefin polymer and a polyfunctional acrylate compound; a gas barrier laminated film having a primer layer made of a cured product of the curable composition; and a gas barrier laminate including an organic compound-containing layer laminated on the surface of the gas barrier laminated film. The present invention provides: a curable composition that is for forming a primer layer suitably used in manufacturing a gas barrier laminate excellent in interlayer adhesion, a gas barrier laminated film having a primer layer made of the cured product of the curable composition, and a gas barrier laminate comprising an organic compound-containing layer laminated on the surface of the gas barrier laminated film.

First claim

The invention claimed is:

1. A gas barrier laminate, comprising an organic compound-containing layer laminated on a primer layer constituting an outermost layer of a gas barrier laminated film, wherein the gas barrier laminated film comprises a gas barrier layer and the primer layer in direct contact with the gas barrier layer, wherein
the gas barrier layer is made of a gas barrier film,
the primer layer is made of a cured product of a curable composition comprising at least a polar group-containing polyolefin polymer, a polyfunctional acrylate compound, and a silane coupling agent and,
the organic compound-containing layer is a protective layer, an adhesive layer, or a quantum dot layer.

2. The gas barrier laminate according to claim 1 , wherein a content of the polyfunctional acrylate compound is 5 to 30 parts by mass based on 100 parts by mass of the polar group-containing polyolefin polymer.

3. The gas barrier laminate according to claim 1 , wherein the curable composition further comprises a polyisocyanate crosslinking agent, and wherein a content of the polyisocyanate crosslinking agent is 1 to 10 parts by mass based on 100 parts by mass of the polar group-containing polyolefin polymer.

4. The gas barrier laminate according to claim 1 , wherein a content of the silane coupling agent is 0.01 to 5 parts by mass based on 100 parts by mass of the polar group-containing polyolefin polymer.

5. The gas barrier laminate according to claim 1 , wherein a content of the silane coupling agent is 0.01 to 3 parts by mass based on 100 parts by mass of the polar group-containing polyolefin polymer.

6. The gas barrier laminate according to claim 1 , wherein the gas barrier film has a thickness of 0.5 to 500 μm.

7. The gas barrier laminate according to claim 1 , wherein the gas barrier film is a laminated film comprising a resin substrate and a layer containing an inorganic compound and/or a metal.

8. The gas barrier laminate according to claim 7 , wherein the layer containing the inorganic compound and/or the metal is a silicon-containing polymer compound layer having a modified surface.

9. The gas barrier laminate according to claim 1 , wherein the primer layer has a thickness of 0.05 to 2.5 μm.

10. The gas barrier laminate according to claim 1 , further comprising another layer in direct contact with the gas barrier layer.
