Abstract

The present disclosure relates to a method for producing a decorative panel. The method comprises the following method steps in order to generate an especially realistic perceptive impression of a structuring, even with a lacquer-containing top layer: a) providing a carrier, b) applying a decoration onto at least a partial region of the carrier, c) applying a lacquer-containing top layer onto the decoration, wherein the method is characterized in that d) the lacquer-containing top layer is partially hardened, wherein d1) a partial hardening of the top layer is realized while forming a hardening gradient and wherein the hardening gradient is established in the direction of the thickness of the top layer such that a surface region of the top layer is hardened comparably stronger than a deeper-lying region of the top layer, and wherein e) subsequent to the only partial hardening of the top layer the latter it is provided with a structuring, wherein f) method step e) is realized at least partially by a negative structuring, and g) the lacquer-containing top layer is final hardened after method step e). The invention further relates to a decorative panel.

First claim

What is claimed:

1. A decorative panel comprising a carrier, a decoration and an unstructured lacquer-containing top layer, wherein the unstructured top layer is partially hardened at an intermediate stage such that a crosslinking degree in a range from ≥50% to ≤90% is obtained, wherein the top layer is partially hardened such that a hardening gradient is obtained in the thickness direction of the top layer, and wherein a surface region of the top layer is hardened comparably stronger than a deeper-lying region of the top layer, wherein the surface region of the top layer is structured by embossing when the decorative panel is at the intermediate stage and exhibits stability to maintain the embossed structure until a complete hardening stage is reached, wherein the partially hardened surface region at the intermediate stage imparts a structure imitating a decorative template into the deeper-lying region of the top layer by negative patterning.

2. The decorative panel according to claim 1 , wherein the lacquer-containing top layer comprises an acrylate-based lacquer.

3. The decorative panel according to claim 1 , wherein the top layer at least partially has a pendulum hardness in a range from ≥65 to ≤80 seconds.
