Decorative Panel, and Decorative Floor Covering Consisting of Said Panels

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 an alloy of a polymer matrix and/or a magnesium cement based matrix and elastic particles dispersed in said matrix, wherein the elastic particles are bond to the polymer matrix and/or the magnesium cement based matrix,
• wherein the elastic particles have a greater elasticity than the polymer matrix and/or the magnesium cement based matrix, and wherein the polymer matrix and/or the magnesium cement based matrix comprises thermoplastic material, and
• wherein the core comprises at least one catalyst to promote the formation of covalent bonds between the polymer matrix and/or the magnesium cement based matrix and the dispersed elastic particles.
