Abstract

The invention relates to a decorative surface covering element, in particular a floor panel, ceiling panel or wall panel. The invention also relates to a panel covering, such as a floor covering, ceiling covering or wall covering, including a plurality of panels. The invention further relates to a method of producing a decorative surface covering element.

Claims (32)

1 . A decorative surface covering element, in particular a decorative panel, such as a floor panel, ceiling panel or wall panel, comprising:

a core provided with an upper side and a lower side,

a decorative top structure affixed, directly or indirectly, on said upper side of the core, said decorative top structure comprising:

at least one decorative print layer forming at least one decor image,

a substantially transparent or translucent three-dimensional embossing structure at least partially covering said print layer, wherein the embossing structure is a multi-layer embossing structure which comprises:

at least one, at least partially cured base layer provided with a plurality of indentations, and

at least one at least partially cured elevated pattern layer formed by a plurality of elevations digitally printed on top of said base layer,

wherein at least a part of an upper surface of the embossing structure is provided with a roughened texture, and

at least one finishing layer at least partially covering the roughened embossing structure.

2 . The surface covering element according to claim 1 , wherein the upper side of the base layer defines an embossing base level, and wherein the indentations and at least a part of the elevations are situated at opposite sides of said embossing base level.

3 . The surface covering element according to claim 1 , wherein the upper side of the base layer defines a base level, and wherein the indentations and at least a part of the elevations are situated at the upper side of said base level.

4 . The surface covering element according to claim 1 , wherein a part of the base layer is provided with said plurality of indentations, and wherein another part of the base layer is free of indentations.

5 . The surface covering element according to claim 4 , wherein at least a part of the elevations are printed on the part of the base layer which is free of indentations.

6 . The surface covering element according to claim 1 , wherein the plurality of indentations of the base layer forms a discontinuous indentation pattern.

7 . The surface covering element according to claim 1 , wherein the base layer is a printed base layer.

8 . The surface covering element according to claim 1 , Wherein at least a part of the indentations of the base layer is aligned in register with at least a part of at least one decor image formed by the decorative print layer.

9 . The surface covering element according to claim 1 , wherein a colored coating is provided in the indentations and onto the base layer.

10 . The surface covering element according to claim 1 , wherein the base layer comprises acrylic resin.

11 . The surface covering element according to claim 1 , wherein the elevated pattern layer comprises acrylic resin.

12 . The surface covering element according to claim 1 , wherein the at least one finishing layer is applied and wherein the upper surface of the embossing structure is entirely covered by one of the at least one finishing layer, wherein, the at least one finishing layer comprises a lacquer layer.

13 . The surface covering element according to claim 1 , wherein the at least one finishing layer is applied and wherein one of the at least one finishing layer is free of any roughened texture.

14 . The surface covering element according to claim 1 , wherein at least a part of the decorative layer is printed directly onto the upper side of the core.

15 . The surface covering element according to claim 1 , wherein the upper side of the core is provided with a carrier layer, wherein the carrier layer comprises a primer or a film, wherein at least a part of the decorative layer is printed directly onto the carrier layer.

16 . The surface covering element according to claim 1 , wherein in between the printed decorative layer and the embossing structure at least one intermediate layer is situated, wherein at least one intermediate layer is formed by a transparent or translucent light reflective thermoplastic layer, wherein the transparent or translucent light reflective thermoplastic layer comprises a polyester layer or a polyethylene terephthalate layer, wherein said transparent or translucent light reflective thermoplastic layer is glued onto the printed decorative layer.

17 . The surface covering element according to claim 1 , wherein a first panel edge comprises a first coupling profile, and a second panel edge, preferably opposite to the first panel edge, comprising a second coupling profile being designed to engage interlockingly with said first coupling profile of an adjacent panel, both in horizontal direction and in vertical direction, wherein the first coupling profile and the second coupling profile are configured such that two of such surface covering elements can be coupled to each other by means of a lowering movement.

18 . The surface covering element according to claim 1 , wherein the core is at least partially foamed.

19 . The surface covering element according to claim 1 , wherein the core comprises at least one composite material of at least one polymeric material and at least one non-polymeric material.

20 . The surface covering element according to claim 1 , wherein the embossing structure comprises a plurality of base layers and/or a plurality of elevated pattern layers.

21 . The surface covering element according to claim 1 , wherein the roughened texture is brushed roughened texture.

22 . The surface covering element according claim 1 , wherein the base layer and/or the pattern layer comprises a water based ink composition.

23 . The surface covering element according to claim 1 , wherein the roughened texture is provided to at least a part of the base layer and to at least a part of the pattern layer.

24 . The surface covering element according to claim 1 , wherein the embossing structure is a printed embossing structure, and wherein at least a part of an upper surface of the printed embossing structure is provided with the roughened texture.
