▎ 摘　　要

NOVELTY - Decorative panel, preferably a floor panel, ceiling panel or wall panel, comprises: a core provided with an upper side and a lower side; a decorative top structure affixed, either directly or indirectly, on the upper side of the core; a first panel edge comprising a first coupling profile; and a second panel edge comprising a second coupling profile being designed to engage interlockingly with the first coupling profile of an adjacent panel, both in horizontal direction and in vertical direction, where the core comprises at least one wool layer at least partially formed by man-made vitreous fibers bonded together by at least one cured thermoset polymeric binder material, and the decorative top structure comprises at least one glaze layer, and optionally at least one digitally printed decorative layer covered by the glaze layer. The fraction of the man-made vitreous fibers are made of at least one material comprising stone wool, mineral wool, slag wool, basalt wool, or glass fibers. USE - The panel is useful as a floor panel, ceiling panel or wall panel for decorative covering, preferably a decorative floor covering, decorative ceiling covering, or decorative wall covering (all claimed). ADVANTAGE - The panel: is profiled relatively smoothly; has coupling profiles which exhibit a reduced risk of breakage; utilizes graphene and/or graphene derivate(s), preferably when applied as part of a porous microstructure, which provide sound absorption properties, and hence acoustic dampening properties, can be enhanced significantly; utilizes graphene that is a two dimensional layer of carbon atoms, arranged in the form of a honeycomb lattice, this thin, one atom thick lattice is relatively strong, flexible, light-weight, and easy to process, which makes this material very suitable to be incorporated in a decorative panel to improve its impact resistance; and utilizes graphene which exhibits excellent heat and electricity conducting properties, excellent antioxidant, antimicrobial properties and scratch-resistant properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) the core for use in the decorative panel; and (2) decorative covering, preferably a decorative floor covering, decorative ceiling covering, or decorative wall covering, comprising the mutually coupled decorative panel. DESCRIPTION OF DRAWING(S) - The figure shows in transversal cross-section the first coupling part at side edge. Side edge (3) First coupling part (5) Coupling part (6) Sideward tongue (20) Upper lip (31)
