The invention relates to a panel, in particular a decorative panel, a floor panel, a ceiling panel or a wall panel. The invention also relates to a floor covering consisting of a plurality of mutually coupled panels. ## Claims ### Claim 1 A decorative panel, comprising: a core provided with an upper side and a lower side, a decorative top structure affixed on said 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 said first coupling profile of an adjacent panel, both in horizontal direction and in vertical direction, wherein said core comprises: at least one polymer, and a plurality of different plasticizers, including: at least one plasticizer selected from the group (A) consisting of: A cyclohexanoate; A citrate; An adipate; A phosphate ester; An azelate; A trimellitate; A dibenzoate; 1,2-benzenedicarboxylic acid; and PVB (polyvinyl butyral); and one additional plasticizer selected from the group (B) consisting of: DOTP (Dioctyl terephthalate); DINP (Di-isononyl phthalate); and DIDP (Di-isodecyl phthalate). ### Claim 2 (depends on 1) The panel according to claim 1, wherein at least one polymer and/or at least one plasticizer used in the core is a recycled material. ### Claim 3 (depends on 1) The panel according to claim 1, wherein at least one polymer of the core is chosen from the group consisting of: PVC (polyvinyl chloride), PUR (polyurethane), a polyolefin, and polystyrene. ### Claim 4 (depends on 1) The panel according to claim 1, wherein at least one polymer of the core is formed by PVB (polyvinyl butyral). ### Claim 5 (depends on 1) The panel according to claim 1, wherein the core comprises 100 parts of polyvinyl chloride and from 20 to 200 parts of total plasticizer. ### Claim 6 (depends on 1) The panel according to claim 1, wherein the panel comprises a backing layer applied, directly or indirectly, to a rear surface of the core, wherein said backing layer comprises at least one polymer and at least one plasticizer selected from the group (A). ### Claim 7 (depends on 6) The panel according to claim 6, wherein the at least one polymer of the backing layer is formed by PVB (polyvinyl butyral). ### Claim 8 (depends on 6) The panel according to claim 6, wherein the core and/or the backing layer comprises at least one filler chosen from the group (C) consisting of: a mineral, a pigment, a modifier, fibers. ### Claim 9 (depends on 1) The panel according to claim 1, wherein the core comprises cellulose based particles. ### Claim 10 (depends on 8) The panel according to claim 8, wherein the core comprises at least one additional filler selected from the group (D) consisting of: steel, glass, polypropylene, wood, acrylic, alumina, curaua, carbon, cellulose, coconut, kevlar, nylon, perlon, polyethylene, PVA, rock wool, sisal, and fique. ### Claim 11 (depends on 1) The panel according to claim 1, wherein the core is at least partially foamed. ### Claim 12 (depends on 1) The panel according to claim 1, wherein the panel comprises at least one reinforcement layer. ### Claim 13 (depends on 1) The panel according to claim 1, wherein the panel comprises a plurality of reinforcement layers. ### Claim 14 (depends on 1) The panel according to claim 1, wherein the first coupling profile comprises: an upward tongue, at least one upward flank lying at a distance from the upward tongue, an upward groove formed in between the upward tongue and the upward flank wherein the upward groove is adapted to receive at least a part of a downward tongue of a second coupling profile of an adjacent panel, and at least one first locking element, and wherein the second coupling profile comprises: a first downward tongue, at least one first downward flank lying at a distance from the downward tongue, a first downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of an upward tongue of a first coupling profile of an adjacent panel, and at least one second locking element adapted for co-action with a first locking element of an adjacent panel. ### Claim 15 (depends on 1) The panel according to claim 1, wherein the panel comprises at least one third coupling profile and at least one fourth coupling profile located respectively at a third panel edge and a fourth panel edge, wherein the third coupling profile comprises: a sideward tongue extending in a direction substantially parallel to the upper side of the core, at least one second downward flank lying at a distance from the sideward tongue, and a second downward groove formed between the sideward tongue and the second downward flank, wherein the fourth coupling profile comprises: a third groove configured for accommodating at least a part of the sideward tongue of the third coupling profile of an adjacent panel, said third groove being defined by an upper lip and a lower lip, wherein said lower lip is provided with an upward locking element, wherein the third coupling profile and the fourth coupling profile are configured such that two of such panels can be coupled to each other by means of a turning movement, wherein, in coupled condition: at least a part of the sideward tongue of a first panel is inserted into the third groove of an adjacent, second panel, and wherein at least a part of the upward locking element of said second panel is inserted into the second downward groove of said first panel. ### Claim 16 (depends on 1) The panel according to claim 1, wherein the core comprises oil. ### Claim 17 (depends on 1) The panel according to claim 1, wherein the core comprises at least one additive chosen from the group consisting of: silica fume, iron oxide, fatty acids, and alkali metal sulfate. ### Claim 18 (depends on 1) A decorative covering, comprising a plurality of mutually coupled decorative panels according to claim 1.
