Abstract

The present invention relates to a panel, in particular a wall, ceiling or floor panel, comprising a carrier plate ( 12 ) based on polyvinyl chloride with a density of, for example, 900 to 2,500 kg/m 3 and a film ( 17 ) applied thereon. The film is a thin PVC-film and comprises a decorative pattern ( 18 ) directly printed thereon.

Claims (25)

1. A panel comprising a carrier plate based on polyvinyl chloride and a film attached thereto, wherein the film is a PVC film having a thickness of 0.04 to 0.2 mm and comprising a decorative pattern directly printed thereon, and a cured polymer layer is provided over the PVC film, wherein the decorative pattern was printed using a UV printing ink that was solvent based, and wherein the printing ink was partially dissolved in the surface of the PVC film.

2. The panel according to claim 1 , wherein the polymer layer comprises a hardness gradient, so that the hardness of the polymer layer decreases essentially continuously with increasing depth as seen from the surface of the polymer layer.

3. The panel according to claim 1 , wherein the printing ink used for printing the decorative pattern is a UV printing ink.

4. The panel according to claim 3 , wherein the polymerizable printing ink contains a polymerizable acrylate and/or N-vinylcaprolactam.

5. The panel according to claim 4 , wherein the polymerizable printing ink for printing the decorative pattern contains a polymerizable acrylate and N-vinylcaprolactam in a weight proportion in the ink of 2 to 50%.

6. The panel according to claim 1 , wherein the printing ink and the polymer layer are cured together, preferably by radiation.

7. The panel according to claim 1 , wherein the decorative pattern was applied by means of digital printing.

8. The panel according to claim 1 , wherein the PVC film has a thickness from 0.05 to 0.15 mm.

9. The panel according to claim 1 , wherein the carrier plate comprises a thickness between 3 and 20 mm.

10. The panel according to claim 1 , wherein a layer comprising a UV primer is provided on the PVC film.

11. The panel according claim 10 , wherein the layer comprising a UV primer has a surface mass of 1 to 15 g/m 2 .

12. The panel according to claim 1 , wherein the PVC film is glued or thermally welded to the carrier plate.

13. The panel according to claim 1 , wherein the PVC film is unicoloured and in particular white.

14. The panel according to claim 1 , wherein abrasion-resistant particles are provided in the polymer layer, wherein the abrasion-resistant particles preferably comprise an average diameter of 10 to 150 μm.

15. The panel according to claim 1 , wherein the polymer layer base on one or more of the following acrylates: 1,6-hexane dioldiacrylate, polyester acrylate, polyurethane acrylic acid ester and dipropylene glycol diacrylate.

16. A method for manufacturing a panel, comprising the following steps in the given order:

(i) providing a carrier plate based on polyvinyl chloride with a density of 900 to 2,500 kg/m 3 ;

(ii) applying a PVC film having a thickness of 0.04 to 0.2 mm to the carrier plate by means of a calender;

(iii) printing a decorative pattern on the PVC film using a UV printing ink that is solvent based, and wherein the printing ink partially dissolves the surface of the PVC film;

(iv) applying a first polymer layer to the PVC film;

(v) optionally applying at least a second liquid polymer layer to the still wet first polymer layer so that a partial mixing of the polymer layers occurs; and

(vi) curing the polymer layer(s).

17. The method according to claim 16 , wherein the steps (iv) to (vi) are performed such that the cured polymer layer has a hardness gradient, wherein the hardness of the coating decreases with increasing depth as seen from the surface of the resulting coating.

18. The method according to claim 17 , wherein a heated calender is used in step (ii) in such a way that the PVC film is thermally welded to the carrier plate.

19. The method according to claim 18 , wherein the decorative pattern is directly printed on the PVC film by means of digital printing.
