Abstract

The invention relates to a decorative panel, comprising at least one substrate comprising an upper surface and a bottom surface and two pairs of opposing side edges, wherein the substrate comprises at least one core layer and at least one decorative layer and the panel comprising at least one coating layer, wherein the coating layer is provided upon the upper surface of the substrate, wherein both the upper surface of the substrate and the upper coating surface of the coating layer have a predetermined Shore D hardness.

Claims (29)

1. A decorative panel, the panel comprising:

at least one substrate comprising an upper surface and a bottom surface, wherein the substrate comprises:

at least one core layer; and

at least one decorative layer; and

at least one coating layer, wherein the coating layer is provided upon the upper surface of the substrate;

wherein the upper surface of the substrate has a Shore D hardness of at least 80 and wherein the coating layer has a Shore D hardness of at least 85, and wherein the core layer has a Vicat softening temperature of at least 80 degrees Celsius.

2. The panel according to claim 1 , wherein the coating layer is directly provided upon the decorative layer of the substrate.

3. The panel according to claim 1 , wherein the coating layer has a Shore D hardness of at least 90.

4. The panel according to claim 1 , wherein the coating layer comprises at least one thermosetting resin and/or wherein the coating layer comprises at least one crosslinkable prepolymer and at least one photo-initiator.

5. The panel according to claim 1 , wherein the coating layer comprises a plurality of abrasion resistant particles-selected, from aluminum oxide, corundum, silicon carbide, titanium dioxide, titanium oxide, diamond particles, or combinations thereof.

6. The panel according to claim 5 , wherein the coating layer comprises abrasion resistant particles in the range of 0.5 to 5 wt %.

7. The panel according to claim 1 , wherein the coating layer is substantially transparent.

8. The panel according to claim 1 , wherein the coating layer comprises at least one matting agent.

9. The panel according to claim 1 , wherein the coating layer has a thickness in the range of 0.01 mm to 0.30 mm.

10. The panel according to claim 1 , wherein the surface roughness of the coating layer is at least 3 μm Ra.

11. The panel according to claim 1 , wherein the upper surface of the substrate has a Shore D hardness of at least 85.

12. The panel according to claim 1 , wherein the at least one decorative layer comprises a thermoplastic film or a ply of cellulose.

13. The panel according to claim 1 , wherein the core layer comprises at least one pair of opposite side edges, and wherein each pair of opposite side edges is provided with one or more complementary coupling parts.

14. A method for producing a decorative panel, comprising the steps of:

a) providing at least one substrate comprising an upper surface and a bottom surface and two pairs of opposing side edges, wherein the substrate comprises:

at least one core layer; and

at least one decorative layer; and

wherein the upper surface of the substrate has a Shore D hardness of at least 80; and wherein the core layer has a Vicat softening temperature of at least 80 degrees Celsius, and

b) applying at least one coating layer upon the upper surface of the substrate, wherein the coating layer is a crosslinkable coating layer;

c) curing said coating layer such that a crosslinked coating layer having a Shore D hardness of at least 85 is obtained.

15. The method according to claim 14 , wherein the coating layer comprises at least one crosslinkable prepolymer and at least one photo-initiator and/or wherein the coating layer comprises at least one thermosetting resin.

16. The method according to claim 14 , comprising the step of applying a texture to the upper surface of the substrate.

17. The method according to claim 14 , wherein the curing step is an UV curing step.

18. The method according to claim 14 , wherein the coating layer comprises a plurality of abrasion resistant particles selected from aluminum oxide, silicon carbide, titanium dioxide, titanium oxide, and/or diamond particles, or combinations thereof.
