Abstract

There is provided a laminate excellent in dimensional stability under high temperature and high humidity despite the fact that the laminate includes resin films.
A laminate according to an embodiment of the present invention includes a plurality of resin films with hard coat layers, which are laminated together, the plurality of resin films with hard coat layers each including a base layer containing a thermoplastic resin and a hard coat layer containing a curable resin, the hard coat layer being formed on the base layer.

First claim

1 . A laminate, comprising a plurality of resin films with hard coat layers, which are laminated together, the plurality of resin films with hard coat layers each including a base layer containing a thermoplastic resin and a hard coat layer containing a curable resin, the hard coat layer being formed on the base layer.

2 . A laminate according to claim 1 , wherein the laminate has a lamination construction vertically symmetric with respect to a center line in a thickness direction thereof.

3 . A laminate according to claim 1 , wherein a number of the resin films with hard coat layers is two.

4 . A laminate according to claim 1 , wherein the plurality of resin films with hard coat layers are bonded to each other through an adhesive layer or a pressure-sensitive adhesive layer.

5 . A laminate according to claim 2 , wherein the respective base layers of the two resin films with hard coat layers are bonded to each other through the adhesive layer or the pressure-sensitive adhesive layer.

6 . A laminate according to claim 2 , wherein the respective hard coat layers of the two resin films with hard coat layers are bonded to each other through the adhesive layer or the pressure-sensitive adhesive layer.

7 . A laminate according to claim 3 , wherein:
the laminate comprises the two resin films with hard coat layers; and the base layer of one of the resin films with hard coat layers and the hard coat layer of another of the resin films with hard coat layers are bonded to each other through the adhesive layer or the pressure-sensitive adhesive layer.

8 . A laminate according to claim 1 , wherein the laminate has a total light transmittance of 80% or more.

9 . A laminate according to claim 1 , wherein the thermoplastic resin in the base layer comprises a (meth)acrylic resin.

10 . A transparent conductive film, comprising:
the laminate of claim 1 ; and a transparent conductive layer formed on the laminate.

11 . A transparent conductive film according to claim 10 , wherein the transparent conductive layer contains a metal nanowire.

12 . A transparent conductive film according to claim 10 , wherein the transparent conductive layer contains a metal mesh.

13 . A transparent conductive film according to claim 10 , wherein the transparent conductive layer contains a polythiophene-based polymer.
