Abstract

Laminate panel, which consists at least of a substrate, a decor and a transparent synthetic material layer, wherein the synthetic material layer is provided with a relief with elongate recesses, wherein the recesses have a cross-section with inclined flank portions, the inclination of which is more than 60° and less than 90°, and that the maximum depth over which said flank portions extend is larger than the maximum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said panel.

First claim

The invention claimed is:

1. A laminate panel, wherein the panel consists at least of a substrate and a decor provided thereon, protected by means of a transparent synthetic material layer,
wherein the synthetic material layer is provided with a relief comprising elongate recesses, wherein said elongate recesses over the major part of their length have a cross-section which is provided with inclined lateral flanks,
wherein these lateral flanks both have a flange portion with an inclination of more than 60° and less than 90°, and that the maximum depth over which said flank portions extend is larger than the maximum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said panel,
wherein said transparent synthetic material layer as such has a portion having a uniform gloss degree of more than 10, measured according to DIN 67530, and
wherein said portion of the surface includes said flanks of the recesses.

2. The laminate panel according to claim 1 , wherein the minimum distance between the respective flank portions, measured in transverse direction and parallel to the plane of said panel, is smaller than half of said maximum distance between these flank portions.

3. The laminate panel according to claim 1 , wherein for said transparent synthetic material layer, use is made of a thermally hardening synthetic material, being melamine.

4. The laminate panel according to claim 1 , wherein for said decor, use is made of a colored or printed material layer, being a paper layer.

5. The laminate panel according to claim 1 , wherein said elongate recesses have the form of wood pores.

6. The laminate panel according claim 1 , wherein said maximum depth is 0.1 millimeter or more.

7. The laminate panel according claim 1 , wherein the deepest point of said recess is located above the horizontal plane in which the decor extends locally.

8. The laminate panel according to claim 1 , wherein said lateral flanks at the entrance of said recess and above the respective inclined flank portion are made with a rounding, wherein said rounding has a radius of less than 0.2 millimeters.

9. The laminate panel according to claim 1 , wherein the length of said recess is at least 10 times the aforementioned maximum distance between the respective flank portions.

10. The laminate panel according to claim 1 , wherein the cross-section of the elongate recesses are configured in a way such that a mirroring reflection of perpendicular or approximately perpendicular incident light takes place mainly on a bottom of the elongate recess.
