Abstract

A transparent conductive gas barrier laminate according to the present disclosure includes a transparent gas barrier film and a transparent conductive layer in this order from outside toward inside. In the laminate, the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system, and the transparent conductive layer contains a conductive polymer and has a b* value of less than 0 in the L*a*b* color system.

First claim

What is claimed is:

1. A transparent conductive gas barrier laminate, comprising:
a transparent gas barrier film and a transparent conductive layer, which is in direct physical contact with the transparent gas barrier film, wherein
the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system;
the transparent conductive layer contains a conductive polymer and has a b* value of less than 0 in the L*a*b* color system,
the transparent gas barrier film includes at least two pairs of films, each pair being a transparent base film and a barrier layer that is formed on at least one surface of the transparent base film, and further includes an adhesive layer interposed between the two pairs of films,
the barrier layer in each pair comprises a silicon oxide-deposited layer and the transparent base film in each pair is a polyethylene terephthalate film or a polyethylene naphthalate film, and
the adhesive layer is formed by curing an adhesive consisting of an epoxy resin, an amine-based curing agent and optionally, a UV absorber.

2. The transparent conductive gas barrier laminate of claim 1 , wherein the transparent gas barrier film has ultraviolet shielding properties.

3. The transparent conductive gas barrier laminate of claim 1 , wherein the UV absorber is present in the adhesive.

4. The transparent conductive gas barrier laminate of claim 3 , wherein the UV absorber is at least one of a benzotriazole-based compound, a benzophenone-based compound, or a triazine-based compound.

5. The transparent conductive gas barrier laminate of claim 1 , the laminate further comprising a coating layer, which is a layer of the laminate furthest from the transparent conductive layer.

6. The transparent conductive gas barrier laminate of claim 5 , wherein the coating layer has a pencil hardness of 2H or more.

7. The transparent conductive gas barrier laminate of claim 1 , wherein the transparent conductive layer has a sheet resistance in a range of 100 Ω/sq to 1000 Ω/sq.

8. The transparent conductive gas barrier laminate of claim 1 , wherein the laminate has a b* value of less than 0 in the L*a*b* color system.

9. The transparent conductive gas barrier laminate of claim 1 , wherein a thickness of the transparent base film is from 12 microns to 30 microns.

10. The transparent conductive gas barrier laminate of claim 1 , wherein the barrier layer further comprises a gas barrier covering layer, the gas barrier covering layer comprising a water soluble polymer and a metal alkoxide.

11. The transparent conductive gas barrier laminate of claim 1 , wherein the adhesive layer has an oxygen permeability from 0.1 cm 3 /(m 2 ·day·atm) to 10 cm 3 /(m 2 ·day·atm).

12. A device, comprising:
the transparent conductive gas barrier laminate of claim 1 , and

a driven unit that is disposed so as to face the transparent conductive layer of the transparent conductive gas barrier laminate.

13. The device of claim 12 , wherein the laminate further comprises a transparent resin film having ultraviolet shielding properties, wherein the transparent resin film faces a second side of the transparent conductive layer, which is opposite to a first side of the transparent conductive layer facing the driven unit.
