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 glass, comprising:

two glass plates; and

a light control film being sandwiched between the two glass plates, and the 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;

a thickness of the light control layer is from 10 to 200 μ

m;

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

m; and

the light control suspension contains a dispersing medium and light control particles dispersed in the dispersing medium,

wherein the light control particles are polyiodide, and

wherein the glass plates each have a curved surface.

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

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

10. The light control glass according to claim 1, wherein the dispersing medium is a (meth) acrylic acid ester oligomer having a fluoro group and/or a hydroxyl group.

4. A light control glass, comprising:

two glass plates; and

a light control film being sandwiched between the two glass plates, and the light control film comprising;

two transparent electroconductive resin substrates; and
