Abstract

A method for the production of grounded panels and to a panel having a core made from a wood material board. The method includes provision of a wood material board, application of a grounding in the form of a synthetic resin layer to at least one topside of the wood material board, application of a coating to an underside, lying opposite the topside of the wood material board, of the wood material board, pressing of the layer build-up consisting of the wood material board, grounding and coating under the influence of pressure and, if appropriate, temperature, division of the grounded and coated wood material board into individual panels, cutting machining of side faces of the panels for the incorporation of connection and locking means, and transport-safe packaging of the grounded panels.

First claim

What is claimed is:

1 . A panel comprising a core made of wooden material with an upper side, to which only a grounding in the form of a synthetic resin layer and, if appropriate, a primer is applied, with an underside comprising an applied coating, which are pressed together with the core, and connecting and locking devices corresponding to one another provided on at least two opposite side surfaces, wherein for a colour of the upper side of the panel in the CIELAB colour space, a lightness parameter L is greater than 92 and a red-green value A lies between −5 and +5 and a yellow-blue value B lies between −15 and +15.

2 . The panel according to claim 1 , wherein a roughness of the upper side of the panel is less than 20 μm.

3 . The panel according to claim 1 , wherein a roughness of the upper side of the panel is less than 10 μm.

4 . The panel according to claim 1 , wherein the red-green value A lies between −2 and +2.

5 . The panel according to claim 1 , wherein the yellow-blue value B lies between −8 and +8.

6 . The panel according to claim 1 , further comprising a structure in the upper side of the panel.

7 . The panel according to claim 1 , wherein the connecting and locking devices are formed in one piece with the core made of wooden material.

8 . The panel according to claim 1 , wherein the connecting and locking devices corresponding to one another are provided on all the opposite side surfaces.
