5. The panel according to claim 1, wherein the adhesion promoter layer comprises a cured acid-curable and/or radiation-curable adhesion promoter composition.

6. The panel according to claim 5, wherein the adhesion promoter layer comprises a cured aminoplast as adhesion promoter composition, preferably a urea resin, a melamine resin and/or a melamine urea resin.

7. The panel according to claim 5, wherein the adhesion promoter layer comprises a cured acrylate-based adhesion promoter composition, in particular a polyurethane-modified acrylate-based adhesion promoter composition.

8. The panel according to claim 5, wherein the adhesion promoter composition comprises dipentaerythritol acrylate and ethoxylated trimethylpropane triacrylate, preferably in a mass ratio of 1:2 to 3:1.

9. The panel according to claim 5, wherein the adhesion promoter composition additionally comprises water and optionally 2-butoxyethanol, 4-ethylmorpholine, 1,2-benzisothiazol-3(2H)-one, zinc pyrithione, and/or reaction mass of 5-chloro-2methyl-4-isothiazolin-3-one and 2-methyl-2H-isothiazol-3-one.

10. The panel according to claim 1, wherein the lacquer-containing top coat comprises a cured top lacquer, in particular a cured radiation-curable top lacquer.

11. The panel according to claim 1, wherein the lacquer-containing top coat comprises a cured acrylate-based top lacquer, in particular a cured polyurethane-modified acrylate-based top lacquer.

12. A method for producing a panel comprising a structured lacquer surface according to claim 1, comprising at least the method steps: a. providing a base panel comprising a melamine resin layer disposed on a surface of the base panel; b. forming an adhesion promoter layer on the melamine resin layer based on an adhesion promoter composition; and c. forming a lacquer-containing top coat on the adhesion promoter layer on the basis of a top lacquer, wherein the base panel, the adhesion promoter composition and the top lacquer are designed according to claim 1, and wherein the forming of the lacquer-containing top coat comprises structuring and curing the top lacquer, or wherein the base panel, the adhesion promoter composition and the top lacquer are as described above, and wherein the melamine resin layer has been structured, and wherein the forming of the lacquer-containing top coat comprises curing the top lacquer in such a way that the structure of the melamine resin layer is perceivable on the cured top lacquer layer.

13. The method according to claim 12, 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.

14. The method according to claim 12, wherein forming the adhesion promoter layer comprises curing the adhesion promoter composition, preferably by use of electromagnetic radiation and/or thermal curing.

15. The method according to claim 12, wherein the lacquer-containing top coat is cured by use of electromagnetic radiation, in particular by UV radiation and/or IR radiation, preferably with a wavelength in a range from 10 nm to 450 nm.

16. The method according to claim 12, wherein the structuring of the lacquer-containing top coat is carried out by use of a digital printing process, preferably by spraying on a displacement ink by means of an inkjet process.

DRAWINGS

[0125] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

[0126] The disclosure is further explained below with reference to the FIGURE. The FIGURE shows one possible embodiment of the disclosure. In principle, however, combinations or variations of the embodiment are possible within the scope of the disclosure.

[0127] FIG. 1 schematically shows the structure of a panel comprising a structured lacquer surface.

DETAILED DESCRIPTION

[0128] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0129] In detail, FIG. 1 schematically shows the cross-section of a panel 1 comprising a structured lacquer surface. The panel comprises a base panel 2, a melamine resin layer 3, an adhesion promoter layer 4 and a lacquer-containing top coat 5, wherein the melamine resin layer 3 is disposed on one surface of the base panel 2, the adhesion promoter layer 4 is disposed on the melamine resin layer 3, and the lacquer-containing top coat 5 is disposed on the adhesion promoter layer 4, wherein the lacquer-containing top coat 5 is structured.

[0130] In this case, the base panel 2 of the shown embodiment comprises a decorative layer 6 including a decoration. Here, the melamine resin layer 3 is disposed on the decorative layer 6. In addition, the base panel 2 comprises a further melamine resin layer 7, a carrier plate 8 and a backing paper 9.

[0131] The panel 1 was produced by first applying a melamine resin layer 3 onto the decorative layer 6 of the base panel 2 comprising the decorative layer 6, the melamine resin layer 7, the carrier plate 8 and the backing paper 9. An adhesion promoter composition was rolled onto the base panel 2 produced in this way and comprising the melamine resin layer 3 disposed on the surface of the base panel 2 and then cured while forming the adhesion promoter layer 4.

[0132] Subsequently a top lacquer was applied onto the adhesion promoter layer 4, structured by means of a digital printing process and subsequently cured, wherein the structured lacquer-containing top coat 5 was formed.

[0133] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are inter-changeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
