A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

The present invention relates to a dispersion for manufacturing of resin-impregnated papers, as can be used for the manufacturing of abrasion-resistant (micro scratch-resistant) surfaces, such as laminate floors, furniture surfaces or laminates (CPL, HPL). The invention relates also to a corresponding method for manufacturing of such surfaces as well as to corresponding manufactured products. Thereby, the dispersion contains for example (in weight percent) 30 to 75% water and 10 to 65% corundum particles with a particle size of F400 to F2000 as well as further additives in small quantity. This dispersion can be introduced into a liquid amino resin mixture to impregnate paper.

A floor panel may include a substrate and a top layer located above the substrate. The substrate may include a closed cell foamed synthetic material layer with fillers. The closed cell foamed synthetic material layer may have an average density of more than 300 kilograms per cubic meter. The top layer may include a back layer, a printed synthetic material film located above the back layer, and a transparent or translucent synthetic material wear layer located above the printed synthetic material film. The back layer may include a vinyl compound with fillers. The back layer may have a thickness of at least 45 percent of the thickness of the top layer. The floor panel may be rectangular and oblong and may include a pair of long edges and a pair of short edges. The floor panel may include first mechanical coupling parts at the pair of long edges and second mechanical coupling parts at the pair of short edges. The first mechanical coupling parts may allow a horizontal and vertical locking of two of such floor panels using a turning movement along the respective long edges. The first mechanical coupling parts may include a tongue and a groove. The groove may be flanked by an upper lip and a lower lip. The first mechanical coupling parts may include a vertical locking mechanism having a vertically active locking surface at the upper side of the tongue and the lower side of the upper lip, respectively. The first mechanical coupling parts may include a horizontal locking mechanism having a horizontally active locking surface at the lower side of the tongue and the upper side of the lower lip, respectively. The horizontally active locking surfaces and the vertically active locking surfaces may be formed in the material of the closed cell foamed synthetic material layer.

A floor panel may include a substrate and a top layer. The substrate may include a closed cell foamed PVC layer. The top layer may include a back layer, a printed synthetic material film, a transparent or translucent synthetic material wear layer, and a surface layer. The printed synthetic material film may be a printed PVC film. The transparent or translucent synthetic material wear layer may include a vinyl layer, and have a thickness of 1 millimeter or less. The surface layer may include a UV hardened substance. The floor panel may include a pair of long edges with first mechanical coupling parts and a pair of short edges with second mechanical coupling parts. The first mechanical coupling parts may have vertically active locking surfaces, and horizontally active locking surfaces formed in the material of the closed cell foamed PVC layer.

The invention relates to a method for producing a color-changeable decorative surface. In order to provide a decorative surface that can be changed in a particularly simple manner in terms of its coloring by the end consumer and which is particularly cost-effective and resistant, it is provided that at least one layer of a coating agent, which enables the absorption of color particles, is applied.

A floor panel with a substrate and a top layer of laminate, which floor panel, at one or more edges, is provided with a lower edge region, wherein the laminate extends in one piece from the actual upper surface of the substrate over the lower edge region at least up to a point, wherein the laminate surface is situated at a level in a horizontal plane which intersects the substrate, and that the substrate material, at the location of the lower edge region, has the same or a lower density than at the actual upper surface of the substrate material. The invention also relates to a method for realizing such floor panels.

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.

A panel may include a substrate and a top layer provided on the substrate. The top layer may include a printed motif provided on a paper sheet and a transparent or translucent synthetic material layer. The paper sheet may be impregnated with polyurethane or polyisocyanate. The synthetic material of the transparent or translucent synthetic material layer may be polyurethane.
