2:

• Decorative panel according to claim 1, wherein the top coating is an Electron Beam (EB) cured top coating.

3:

• Decorative panel according to claim 1, wherein the top coating has surface density situated between 6 g/m2 and 18 g/m2, preferably between 8 g/m2 and 16 g/m2, more preferably between 10 g/m2 and 14 g/m2.

4:

• Decorative panel according to claim 1, wherein the top coating is chemically bonded to at least one adjacent layer of the covering structure, the at least one adjacent wear layer.

5:

• Decorative panel according to claim 1, wherein the top coating is essentially impermeable for substances, such as an odorous and/or plasticizing substance, optionally present in and/or optionally making part of other layers of the decorative panel.

6:

• Decorative panel according to claim 1, wherein the at least one layer of the multi-layered covering structure, preferably the top coating, is cured at an irradiation dose situated between 20 kGy and 50 kGy, preferably between 30 kGy and 40 kGy.

7:

• Decorative panel according to claim 1, wherein the top coating is provided, directly or indirectly, on an upper surface of the wear layer.

8:

• Decorative panel according to claim 1, wherein the top coating is a substantially uniform top coating.

9:

• Decorative panel according to claim 1, wherein at least one layer of the printed multi-layered covering structure, in particular the wear layer, is formed by a substantially transparent or translucent three-dimensional embossing structure at least partially covering said decorative print layer.

10:

• Decorative panel according to claim 9, wherein the embossing structure comprises at least one, at least partially cured base layer provided with a plurality of indentations.

11:

• Decorative panel according to claim 9, wherein the embossing structure further comprises at least one at least partially cured elevated pattern layer formed by a plurality of elevations printed on top of said base layer.

12:

• Decorative panel according claim 9, wherein at least a part of the embossing structure is Electron Beam (EB) cured, wherein, preferably, at least the base layer and/or the elevated pattern layer of the embossing structure is an Electron Beam (EB) cured layer.

13:

• Decorative panel according claim 9, wherein the embossing structure is an at least partially printed embossing structure, preferably an at least partially digitally printed embossing structure.

14:

• Decorative panel according to claim 13, wherein a textured upper surface of the embossing structure is at least partially defined by printing, preferably digital printing.

15:

• Decorative panel according to claim 9, wherein a textured upper surface of the embossing structure comprises etched away portions, wherein said etched away portions are realized by Electron Beam curing.

16:

• Decorative panel according to claim 9, wherein at least a part of an upper surface of the embossing structure is provided with an actively roughened texture.

17:

• Decorative panel according to claim 9, wherein at least a part of the embossing structure is EB cured, and wherein at least one other part of the embossing structure is UV cured.

18:

• Decorative panel according to claim 9, wherein the decorative panel further comprises at least one primer layer, preferably situated between the core and the decorative top structure.

19:

• Decorative panel according to claim 18, wherein the primer layer has a surface density situated between 18 g/m2 and 26 g/m2, between 20 g/m2 and 24 g/m2.
