Abstract

Coated panel with at least a substrate ( 2 ) and a top layer applied thereto ( 3 ), wherein the above-mentioned top layer ( 3 ) comprises at least a decor layer ( 4 ) and a translucent or transparent wear layer ( 5 ), characterized in that the above-mentioned wear layer ( 5 ) comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin. Preferably, wherein thermal curing partially or completely cures the resin. In particular, wherein the above-mentioned acrylate resin or unsaturated polyester resin is at least partially cured by means of a thermally initiated radical crosslinking reaction. The invention further relates to a method for the production of such coated panels ( 1 ), in particular floor panels.

Claims (38)

1 .- 65 . (canceled)

66 . A coated panel with at least a substrate and a top layer applied thereto,

wherein the above-mentioned top layer comprises at least a decor layer and a translucent or transparent wear layer;

wherein the wear layer comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin;

wherein the acrylate resin or unsaturated polyester resin is cured by means of a thermally initiated radical crosslinking reaction.

67 . The coated panel as in claim 66 , wherein the wear layer is obtained based on a mixture containing at least on the one hand acrylate resin and/or unsaturated polyester resin and on the other hand a thermoinitiator.

68 . The coated panel as in claim 67 , wherein the thermoinitiator is an organic peroxide, or benzoyl peroxide or lauryl peroxide or tertiary butylperoxy-3,5,5-trimethylhexanoate (TBPIN).

69 . The coated panel as in claim 66 , wherein the wear layer comprises traces of a peroxide.

70 . The coated panel as in claim 66 , wherein the wear layer is cured uniformly or essentially uniformly over its entire thickness.

71 . The coated panel as in claim 66 , wherein the wear layer is obtained based on a mixture containing at least on the one hand acrylate resin and/or unsaturated polyester resin and on the other hand a photoinitiator.

72 . The coated panel as in claim 71 , wherein the mixture comprises 0.1-5 parts of two different photoinitiators per 100 parts of acrylate resin or per 100 parts of unsaturated polyester resin.

73 . The coated panel as in claim 66 , wherein the decor layer comprises a paper sheet provided with synthetic material.

74 . The coated panel as in claim 73 , wherein the wear layer comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin; and

wherein the synthetic material is selected from the list of amino resins, urea formaldehyde, melamine urea formaldehyde, melamine formaldehyde, polyurethane, urethane-acrylic copolymer, melamine acrylate, melamine formaldehyde, acrylate, latex, dispersions.

75 . The coated panel as in claim 66 , wherein the wear layer comprises a thermally cured acrylate resin; and

wherein the acrylate resin at least is obtained based on a multifunctional acrylate monomer and/or oligomer or on a hexafunctional acrylate oligomer.

76 . The coated panel as in claim 66 , wherein the wear layer comprises a thermally cured acrylate resin and wherein the above-mentioned acrylate resin at least is obtained based on a monofunctional or difunctional or a trifunctional acrylate monomer and/or oligomer.

77 . The coated panel as in claim 66 , wherein the wear layer comprises a thermally cured acrylate resin and wherein the acrylate resin at least is obtained with a chemically modified acrylate or with a fluoroacrylate.

78 . The coated panel as in claim 66 , wherein the wear layer comprises a thermally cured acrylate resin; and

wherein the acrylate resin is of the aliphatic type.

79 . The coated panel as in claim 66 , wherein the coated panel has a relief on its surface, wherein the relief comprises gloss differences.

80 . The coated panel, with at least a substrate and a top layer applied thereto,

wherein the top layer comprises at least a decor layer and a translucent or transparent wear layer;

wherein the wear layer comprises an acrylate;

wherein this acrylate comprises covalent bonds formed by reaction of hydroxyl groups with isocyanate groups;

wherein the wear layer comprises a relief, wherein this relief shows gloss differences.

81 . The coated panel as in claim 80 , wherein an adhesion promoter is located between the decor layer and the wear layer.

82 . The coated panel as in claim 80 , wherein the decor layer shows a wood pattern by printing; and

wherein the relief is in register with the wood pattern, said relief showing gloss differences in register with the wood pattern.

83 . The coated panel as in claim 80 , wherein the substrate comprises a thermoplastic,

wherein this thermoplastic comprising one or more of fillers; and

wherein the decor layer comprises a film out of synthetic material or a printed film out of synthetic material; or

wherein the decor layer comprises a print on the substrate.

84 . The coated panel as in claim 80 , wherein the substrate comprises or consists of a wood fiberboard and the decor layer comprises a printed paper sheet;

wherein said printed paper sheet is impregnated with a thermally curing resin.

85 . The coated panel with at least a substrate and a top layer applied thereto,

wherein the top layer comprises at least a decor layer;

wherein between the decor layer and the substrate, a thermally cured acrylate resin or a thermally cured unsaturated polyester resin is located and/or the decor layer is at least partially formed by a thermally cured acrylate resin or a thermally cured unsaturated polyester resin.
