Abstract

Flexible selective energy control sheet construction formed of a sheet of substantially transparent polymer thin film plastic material having first and second surfaces. A substantially transparent continuous adhesion promoting layer is adherent to the second surface of the sheet. A substantially transparent metal layer is adherent to the adhesion promoting layer and a protective layer is adherent to the metal layer. The metal layer is selected from the materials of copper and silver.

Claims

1. In a flexible selective energy control sheet, a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of silver and having a thickness ranging from 60 to 200 Angstroms, said adhesion promoting layer and said protective layer being formed of zinc sulfide and having a thickness ranging from 300 to 500 Angstroms.

2. An energy control sheet as in claim 1 wherein said sheet of transparent flexible polymer plastic material has a thickness ranging from 12 micrometers to 200 micrometers.

3. An energy control sheet as in claim 1 together with a top coat carried by said protective layer.

4. An energy control sheet as in claim 1 together with an adhesive layer carried by said first surface and a release liner carried by said adhesive layer on said first surface.

5. In a flexible selective energy control sheet, a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of copper having a thickness ranging from 100 to 500 Angstroms, said adhesion promoting layer and said protective layer being formed of chromium and having a thickness ranging from 10 to 200 Angstroms.

6. An energy control sheet as in claim 5 wherein said sheet of transparent flexible polymer plastic material has a thickness ranging from 12 to 200 micrometers.

7. An energy control sheet as in claim 5 together with a top coat carried by said protective layer.

8. An energy control sheet as in claim 7 wherein said top coat is comprised of a film having a thickness ranging from 5 to 50 microns.

9. An energy control sheet as in claim 5 together with an adhesive layer carried by said first surface and a release liner carried by said adhesive layer on said first surface.
