Abstract

The present invention relates to a light control film, comprising:

• • two transparent electroconductive resin substrates; and
  • a light control layer sandwiched by the two transparent electroconductive resin substrates,
  • wherein the light control layer contains a resin matrix and a light control suspension dispersed in the resin matrix, and the thickness of the transparent electroconductive resin substrates is from 10 to 80 μm.

Claims

1. A light control film, comprising:

two transparent electroconductive resin substrates; and

a light control layer sandwiched between the two transparent electroconductive resin substrates,

wherein the light control layer contains a resin matrix and a light control suspension dispersed in the resin matrix, and

the thickness of the transparent electroconductive resin substrates is from 10 to 80 μ

m.

3. The light control film according to claim 1, wherein the thicknesses of the two transparent electroconductive resin substrates are equal to each other.

4. The light control film according to claim 1, wherein the thickness of the light control layer is from 10 to 200 μ

m.

5. The light control film according to claim 1, wherein the light control layer has therein no interfacial surface.

6. A light control glass, comprising:

two glass plates; and

a light control film according to claim 1 and,
