Abstract

A translucent decorative board for use, e.g., as a window pane, light shade, partition or door pane is disclosed. The decorative board is comprised of a translucent substrate board and translucent cover sheets bonded to the surfaces of the substrate board. The substrate board is generally thermoplastic and the decorative cover sheets are thermosetting. The thermosetting sheet may comprise a substrate paper sheet and a thermosetting resin impregnated in the sheet.

Claims

1. A decorative board comprising a thermoplastic substrate board and at least one thermosetting sheet hardened and bonded to a surface of said substrate board.

2. A decorative board of claim 1, said thermoplastic substrate board comprising a resin selected from the resin group consisting of acrylic, vinyl chloride, polycarbonate, polyethylene phthalate and olefin resins.

3. A decorative board of claim 1 or 2, said thermosetting sheet comprising a resin selected from the resin group consisting of melemine, diallylphthalate, unsaturated polyester and polyurethane resins.

4. A decorative board of any one of claims 1-3, wherein said thermoplastic substrate board is translucent.

5. A decorative board of any one of claims 1-4, wherein said thermosetting sheet comprises a substrate sheet and a thermosetting resin impregnated in said substrate sheet and hardened.

6. A decorative board of claim 5, wherein said substrate sheet is selected from the sheet group consisting of inorganic and organic fiber woven fabrics and nonwoven fabrics, transparent paper sheets containing less than 1 wt % ash, and conceal paper sheets containing more than 1 wt % ash.

7. A decorative board of any of claims 1-6, which is translucent.

8. A decorative board comprising a translucent substrate board and two translucent decorative sheets, wherein said decorative sheets, being colored identically with or similarly to each other, are respectively bonded to the surfaces of said substrate board.

9. A decorative board of claim 8, said decorative sheets respectively having designed features which are essentially identical with each other.

10. A decorative board of claim 8, said decorative sheets respectively having designed features which are essentially identical with each other and provided essentially at mutually corresponding locations.

11. A decorative board of any of claims 8-10, said substrate board comprising a thermoplastic resin.

12. A decorative board of any of claims 8-11, said substrate board comprising a resin selected from the resin group consisting of vinyl chloride, acrylic, polycarbonate, polyethylene phthalate and olefin resins.

13. A decorative board of any of claims 8-12, each of said decorative sheets comprising a resin impregnated and hardened sheet.

14. A decorative board of any of claims 8-13, wherein said substrate board is a glass pane.
