Claim 0:
1. A method to produce a building panel comprising a thermoplastic material having a microstructured top surface, the microstructured top surface having different gloss levels, the method comprising:
applying a decorative layer onto a core,
applying the thermoplastic material directly onto the decorative layer, wherein the thermoplastic material comprises wear resistant particles substantially encapsulated into the thermoplastic material, the thermoplastic material optionally further including scratch resistant particles and/or additives,
pressing a top surface of the thermoplastic material, which has the encapsulated wear resistant particles, against a pressing device having portions with different gloss levels, such that the top surface of the thermoplastic material directly attached to the decorative layer obtains a microstructure with portions having different gloss levels, the thermoplastic material being substantially transparent,
wherein the microstructure in the top surface of the thermoplastic material has a maximum depth of 30 μm,
further comprising forming embossed portions in the top surface of the thermoplastic material, the embossed portions each having a depth exceeding 100 μm.
