1. A process for the production of a covered panel, the process comprising:
applying a membrane to a panel construct to form a membrane covered panel construct wherein said membrane is adjacent to a surface of said panel construct,
said membrane having been formed by:
applying a liquid elastomeric resin-based material to a transfer film to form a liquid film on the transfer film; and
drying said liquid film so as to form said membrane on said transfer film; and
pressing the membrane covered panel construct under conditions of heat and pressure to cure said elastomeric resin-based material and bond said membrane to said panel construct, wherein the pressing step is carried out in a batch pressing device or in a continuous pressing device, and wherein the pressing device has a textured surface which is transferred to the surface of the membrane covered panel construct in the pressing step,
wherein said membrane is removably attached to said transfer film, said elastomeric resin-based material is a solution or dispersion of an elastomeric resin in a solvent, said elastomeric resin-based material is based on at least one of a resin selected from polyurethane, ethylene vinyl acetate, ethylene vinyl alcohol, polyester, polyolefin, melamine, ethylene styrene, styrene acrylic, rubber based material, and latex, said transfer film is a film material which temporarily adheres to the membrane, both before and after the pressing operation, said transfer film can be peeled, or otherwise removed from the membrane without any damage to the membrane or the transfer film, the panel construct is a decorative panel, and the decorative panel is a flooring panel, a a countertop panel or a wall panel.
