Abstract

A writing or projection surface, such as may be used for white boards, comprising multiple layers of thin films.

Claims

1. A multiuse dry erase writing and projection surface comprising:

(a) a polycarbonate substrate having a front face and a rear face and a thickness of 5 to 20 mil;

(b) a polyester layer provided on the front face having a thickness of 3 to 7 mil;

(c) a dry erase coating provided on the polyester layer; and

,

(d) an adhesive layer provided on the rear face of the polycarbonate substrate.

2. The multiuse dry erase writing and projection surface of claim 1 wherein the polycarbonate substrate has a thickness of about 10 to 20 mil.

3. The multiuse dry erase writing and projection surface of claim 2 wherein the polyester has a thickness of about 5 mil.

4. The multiuse dry erase writing and projection surface of claim 1 wherein the adhesive comprises a releasable adhesive.

5. The multiuse dry erase writing and projection surface of claim 1 further comprising a release layer applied over the adhesive layer.

6. The multiuse dry erase writing and projection surface of claim 1 further comprising a printed layer positioned between the polyester layer and the dry erase coating and the polyester layer is transparent.

7. The multiuse dry erase writing and projection surface of claim 6 wherein the printed layer has a graphic design on the front face thereof.

8. The multiuse dry erase writing and projection surface of claim 7 wherein the printed layer comprises paper.

9. The multiuse dry erase writing and projection surface of claim 7 wherein the graphic design is selected from the group a grid, a sports field, a control board, a schedule and a corporate logo.

10. The multiuse dry erase writing and projection surface of claim 1 wherein the polycarbonate substrate has a graphic design on the front face thereof.

11. The multiuse dry erase writing and projection surface of claim 1 wherein the dry erase coating has a gloss level of 25°

to 45°

as measured using a 60°

gloss meter.

12. A dry erase whiteboard comprising:

(a) a polycarbonate substrate having a front face and a rear face and a thickness of 5 to 20 mil; and

,

(b) a dry erase and projection surface provided on the substrate.

13. The dry erase whiteboard of claim 12 wherein the polycarbonate substrate has a thickness of about 10 to 20 mil.

14. The dry erase whiteboard of claim 12 further comprising a polyester layer provided on the front face and having a thickness of 3 to 7 mil.

15. The dry erase whiteboard of claim 12 wherein the polyester layer has a thickness of about 5 mil.

16. The dry erase whiteboard of claim 12 further comprising an adhesive layer provided on the rear face of the polycarbonate substrate.

17. The dry erase whiteboard of claim 16 wherein the adhesive comprises a releasable adhesive.

18. The dry erase whiteboard of claim 16 further comprising a release layer applied over the adhesive layer.

19. The dry erase whiteboard of claim 12 further comprising a printed layer positioned between the dry erase and projection surface and the polycarbonate layer and the dry erase and projection surface is transparent.

20. The dry erase whiteboard of claim 19 wherein the printed layer has printed thereon a design selected from the group a grid, a sports field, a control board, a schedule and a corporate logo.

21. The dry erase whiteboard of claim 12 wherein the polycarbonate substrate has a graphic design on the front face thereof.

22. The dry erase whiteboard of claim 12 wherein the dry erase and projection surface has a gloss level of 25°

to 45°

as measured using a 60°

gloss meter.
