Abstract

The present disclosure relates to a panel comprising a structured lacquer surface, having a base panel, a melamine resin layer, an adhesion promoter layer and a lacquer-containing top coat, the melamine resin layer being provided on a surface of the base layer, the adhesion promoter layer being provided on the melamine resin layer and the lacquer-containing top coat being provided on the adhesion promoter layer, the lacquer-containing top coat being structured. The disclosure also relates to a method for producing a panel of this type with a structured lacquer surface.

First claim

The invention claimed is:

1. A method for producing a panel comprising a structured lacquer surface including a base panel, a melamine resin layer, an adhesion promoter layer and a lacquer-containing top coat, the melamine resin layer being disposed on a surface of the base panel, the adhesion promoter layer being disposed on the melamine resin layer and the lacquer-containing top coat being disposed on the adhesion promoter layer, the lacquer-containing top coat comprising a structure, the method comprising the consecutive steps:
a. providing a base panel comprising a melamine resin layer disposed on a surface of the base panel;
b. structuring the melamine resin layer;
C. forming on the structured melamine resin layer an adhesion promoter layer based on an adhesion promoter composition; and
d. forming on the adhesion promoter layer a lacquer-containing top coat including a top lacquer,
wherein the forming of the lacquer-containing top coat comprises structuring and curing the top lacquer, or
wherein the adhesion promoter layer and the top lacquer follow a structure of the melamine layer, thereby making a structure identical to the structure of the melamine layer perceivable on the cured top lacquer, wherein the adhesion promoter composition comprises an acid-curable and/or radiation-curable adhesion promoter composition including a polyurethane-modified acrylate-based composition.

2. The method according to claim 1 , wherein forming the adhesion promoter layer comprises applying the adhesion promoter composition onto the melamine resin layer and drying the adhesion promoter composition on the melamine resin layer.

3. The method according to claim 1 , wherein forming the adhesion promoter layer comprises curing the adhesion promoter composition by use of electromagnetic radiation and/or thermal curing.

4. The method according to claim 1 , wherein the lacquer-containing top coat is cured by use of electromagnetic radiation, UV radiation and/or IR radiation.

5. The method according to claim 4 , wherein the lacquer-containing top coat is cured by use of UV radiation and/or IR radiation having a wavelength in a range from ≥10 nm to ≤450 nm.

6. The method according to claim 1 , wherein additional structuring of the lacquer-containing top coat is carried out by use of a digital printing process by spraying on a displacement ink by means of an inkjet process.
