Abstract

A laminated glass 1 includes a resin plate 2 as a core material, a first glass sheet 4 disposed on one surface side of the resin plate 2 via a first adhesive layer 3 , and a second glass sheet 6 disposed on the other surface side of the resin plate 2 via a second adhesive layer 5 . A heat reflective film 7 is disposed in the first adhesive layer 3 , and a heat absorbing film 8 is disposed in the second adhesive layer 5 , the heat absorbing film 8 functioning as a light absorbing member capable of absorbing a portion of incident light. The heat reflective film 7 is disposed closer to the first glass sheet 4 than the heat absorbing film 8 is.

Claims (19)

1. A laminated glass comprising:

a core material including a resin plate;

a first glass sheet disposed on one surface side of the core material via a first adhesive layer;

a second glass sheet disposed on another surface side of the core material via a second adhesive layer;

a heat reflective film disposed in the first adhesive layer; and

a light absorbing film disposed in the second adhesive layer,

wherein the first adhesive layer comprises a first portion provided between the first glass sheet and the heat reflective film, and a second portion provided between the heat reflective film and the core material,

wherein the second adhesive layer comprises a first portion provided between the second glass sheet and the light absorbing film, and a second portion provided between the light absorbing film and the core material,

wherein the heat reflective film is formed as a member separate from the first adhesive layer,

wherein the light absorbing film is formed as a member separate from the second adhesive layer,

wherein the heat reflective film comprises a first substrate and a reflective film formed on the first substrate,

wherein the reflective film is disposed closer to the core material than the first substrate,

wherein the light absorbing film comprises a second substrate and an absorbing film formed on the second substrate, and

wherein the absorbing film is disposed closer to the core material than the second substrate.

2. The laminated glass according to claim 1 , wherein the light absorbing film is a heat absorbing film.

3. The laminated glass according to claim 1 , wherein a thickness of the first portion of the first adhesive layer between the heat reflective film and the first glass sheet is larger than a thickness of the second portion of the first adhesive layer between the heat reflective film and the core material.

4. The laminated glass according to claim 3 , wherein the thickness of the first portion of the first adhesive layer between the heat reflective film and the first glass sheet is 0.3 mm or larger.

5. The laminated glass according to claim 1 , wherein a thickness of the first portion of the second adhesive layer between the light absorbing film and the second glass sheet is larger than a thickness of the second portion of the second adhesive layer between the light absorbing film and the core material.

6. The laminated glass according to claim 5 , wherein the thickness of the first portion of the second adhesive layer between the light absorbing film and the second glass sheet is 0.3 mm or larger.
