Abstract

Provided is method for producing a support material provided with at least one anti-fingerprint coating including the steps of applying at least one layer of at least one powdered resin to at least one side of the support material; melting on the at least one applied layer of the one powdered resin; applying at least one acrylate-containing dispersion to the melted-on resin layer; and drying and curing the layered structure.

First claim

The invention claimed is:

1. A paper layer with anti-fingerprint properties, wherein the paper layer is coated with a matte surface coating comprising:
a melted-on resin powder layer applied to the paper layer; and
a cured acrylate layer, and
wherein the matte surface coating has a gloss level of less than 10.

2. The paper layer according to claim 1 , wherein the paper layer is a decorative paper layer or an overlay paper layer.

3. The paper layer according to claim 1 , wherein the matte surface coating has a gloss level of less than 8.

4. The paper layer according to claim 1 , wherein the matte surface coating has a gloss level of less than 5.

5. The paper layer according to claim 1 , wherein the cured acrylate layer is obtained from a radiation-curable acrylate-containing varnish.

6. The paper layer according to claim 1 obtained in a method comprising the steps of:
applying a layer of at least one powdered resin to at least one side of the paper layer and melting-on the applied layer of powdered resin;
applying an acrylate-containing dispersion fluid to the melted-on resin layer; and
drying and hardening the layered structure.

7. The paper layer according claim 6 , wherein an amount of powdered resin applied to the paper layer is of 10 to 100 g/m 2 .

8. The paper layer according to claim 6 , wherein an amount of the acrylate-containing dispersion fluid applied is between 30 and 50 g/m 2 .

9. The paper layer according to claim 6 , wherein a solids content of the acrylate-containing dispersion fluid applied is between 40 and 60% by weight.

10. A wood-based panel with anti-fingerprint properties, wherein the wood-based panel is coated with a matte surface coating comprising:
a melted-on resin powder layer applied to the wood-based panel; and
a cured acrylate layer,
wherein the matte surface coating has a gloss level of less than 10.

11. The wood-based panel according to claim 10 , wherein the wood-based panel is selected from the group consisting of medium-density fiber (MDF), high-density fiber (HDF), rough particleboard (OSB), a plywood panel, a wood-plastic composite (WPC) panel, and a stone-plastic composite (SPC) panel.

12. The wood-based panel according to claim 10 , wherein the matte surface coating has a gloss level of less than 8.

13. The wood-based panel according to claim 10 , wherein the matte surface coating has a gloss level of less than 5.

14. The wood-based panel according claim 10 , wherein the cured acrylate layer is obtained from a radiation-curable acrylate-containing varnish.

15. The wood-based panel according to claim 10 , further comprising an optional backing layer on an opposite side of the wood-based panel from the matte surface coating,
wherein the matte surface coating comprises, in the following order:
a first resin layer of melted-on resin powder;
printed decorative layer;
a second resin layer of melted-on resin powder; and
the cured acrylate layer.

16. The wood-based panel according to claim 15 obtained in a method comprising the steps of:
forming the first resin layer by applying a layer of at least one powdered resin to one side of the wood-based panel and melting-on the applied layer of powdered resin;
forming the printed decorative layer by applying a decorative layer to the melted-on first resin layer by a direct printing method;
forming the second resin layer by applying a layer of at least one powdered resin to the printed decorative layer and melting-on the layer of the at least one powdered resin deposited on the printed decorative layer;
forming the acrylate layer by applying at least one acrylate-containing dispersion to the melted-on second resin layer; and
drying and hardening the layered structure.

17. The wood-based panel according to claim 10 , further comprising an optional backing layer on an opposite side of the wood-based panel from the matte surface coating,
wherein the matte surface coating comprises, in the following order:
a first resin layer of melted-on resin powder;
an undercoat layer;
a primer layer;
a print decor layer;
a layer of abrasion-resistant particles;
a second resin layer of melted-on resin powder; and
the cured acrylate layer.

18. The wood-based panel according to claim 10 , further comprising an optional backing layer on an opposite side of the wood-based panel from the matte surface coating,
wherein the matte surface coating comprises, in the following order:
a first resin layer of melted-on resin powder;
an undercoat layer;
a primer layer;
a print decor layer;
a second resin layer of melted-on resin powder;
a layer of abrasion-resistant particles;
a third resin layer of melted-on resin powder;
glass beads;
a fourth resin layer of melted-on resin powder; and
the cured acrylic layer.

19. The wood-based panel according to claim 17 , wherein the undercoat layer comprises casein, corn starch, or soy protein.

20. The wood-based panel according to claim 18 , wherein the undercoat layer comprises casein, corn starch, or soy protein.

21. The wood-based panel according to claim 16 , wherein an amount of powdered resin applied to the wood-based panel is of 10 to 100 g/m 2 .

22. The wood-based panel according to claim 16 , wherein an amount of powdered resin applied to the wood-based panel is 20 to 80 g/m 2 .

23. The paper layer according to claim 1 , wherein the cured acrylate layer is obtained from a radiation-curable acrylate-containing varnish selected from the group consisting of polyether (meth)acrylates, epoxy (meth)acrylates, and urethane (meth)acrylates.

24. The paper layer according to claim 6 , wherein an amount of powdered resin applied to the paper layer is 20 to 80 g/m 2 .

25. The paper layer according to claim 6 , wherein an amount of powdered resin applied to the paper layer is 25 to 70 g/m 2 .

26. The paper layer according to claim 6 , wherein an amount of the acrylate-containing dispersion fluid applied is between 30 and 50 g/m 2 .
