Abstract

Panel, in particular a wall, ceiling or floor panel, of a planar design having a top side, a bottom side and side edges, which panel is constructed from a laminate structure of layers that are adhered to each other, wherein the layers include a core layer, a decorative layer which includes a decorative image on its upper side, which decorative layer is provided directly or indirectly on an upper side of the core layer, and a top coat layer that is transparent and includes a layer of transparent matrix material, which top coat layer is provided directly or indirectly on an upper side of the decorative layer.

First claim

The invention claimed is:

1 . A decorative panel, of a planar design having a top side, a bottom side and side edges, which panel is constructed from a laminate structure of layers that are adhered to each other, wherein the layers include:
at least one core layer, at least one decorative layer which comprises a decorative image, which decorative layer is affixed, either directly or indirectly, on an upper side of the core layer, and at least one substantially transparent top coat layer, affixed, either directly or indirectly, on an upper side of the decorative layer, wherein said top coat layer comprises an at least partially transparent matrix material, and a plurality of chips dispersed in said matrix material, wherein the chips have light-interacting properties and comprise one or more of the following types of chips: light reflective chips that have an outer surface of light reflective material, such that more than 50% of incident light is reflected; and light absorbing chips that have an outer surface of light absorbing material, such that more than 50% of incident light is absorbed.

2 . The panel according to claim 1 , wherein the chips are shaped as non-spheroid particles including rectangular or polyhedral particles, or flake-formed particles.

3 . The panel according to claim 1 , wherein the chips are composed of a composite material, which composite material comprises at least one polymeric material and at least one non-polymeric material.

4 . The panel according to claim 1 , wherein the chips comprises at least one polymeric material and at least one light reflective non-polymeric flake.

5 . The panel according to claim 4 , wherein the light reflective non-polymeric flake is at least partially composed of a material chosen from the group consisting of: mica, metal, metal oxide, a non-metal, pearls, and glass flakes.

6 . The panel according to claim 4 , wherein said chips additionally comprises at least one filler dispersed in said polymeric material, wherein said filler selected from the group consisting of: aluminium hydroxide, magnesium hydroxide, calcium hydroxide, zirconium hydroxide, aluminium, calcium carbonate, magnesium oxide, titanium oxide, barium sulphate, silica, quartz, talc, clay, diatomaceous earth, gypsum, powder glass, montmorillonite, bentonite, pyrophyllite, kaolin, powder chalk, marble, limestone, asbestos, mullite, aluminium silicate, aluminium stearate, calcium silicate, anhydrite, α-cristobalite, and alumina white.

7 . The panel according to claim 4 , wherein said composite material comprises a laminate of a first layer based upon said at least one polymeric material, and a second layer based upon the at least one light reflective non-polymeric flake.

8 . The panel according to claim 1 , wherein the chips comprises a cured composition comprising a binder at least partially composed of a halogenated alkoxylated diacrylate oligomer or halogenated alkoxylated dimethacrylate oligomer.

9 . The panel according to claim 1 , wherein the difference in specific gravity between the chips and the matrix material is less than 0.5 g/cm3.

10 . The panel according to claim 1 , wherein the chips have a specific gravity of 1.43 to 1.77 g/cm3.

11 . The panel according to claim 1 , wherein the matrix material has a specific gravity of 1.50 to 1.85 g/cm3.

12 . The panel according to claim 1 , wherein the specific gravity difference between the matrix material and the chips is 1.85 g/cm3 or less.

13 . The panel according to claim 1 , wherein the chips are crushed chips.

14 . The panel according to claim 1 , wherein the at least partially transparent matrix material of the top coat layer comprises a vinyl polymer or a thermosetting polymer material; and at least one non-polymeric additive selected from the group consisting of: aluminium oxide, aluminium hydroxide, barium, precipitated calcium carbonate, stone powders, silica, titanium dioxide, calcium carbonate, metal powder, and a metal salt.

15 . The panel according to claim 1 , wherein the top coat layer, in particular the matrix material, comprises at least one semi-transparent or opaque zone.

16 . The panel according to claim 1 , wherein the chips are positioned in the transparent matrix material such that their position is in correspondence with the decorative image of the decorative layer.

17 . The panel according to claim 1 , wherein the light reflective chips are positioned in correspondence with image parts of the decorative image that are:
image parts of a light colour, or image parts that depict an elevated zone of a depicted relief structure.

18 . The panel according to claim 1 , wherein the light absorbing chips are positioned in correspondence with parts of the decorative image that are:
image parts of a dark colour, or image parts that depict a recessed zone of a depicted relief structure.

19 . The panel according to claim 1 , wherein the panel comprises at least two opposite side edges which are provided with respective interconnecting profiles that are complementary to each other.
