Layered composite based on thermoplastic polymers

A layered composite useful for flooring coverings and wall panels with at least one decorative surface and consisting of a backing layer of a reinforced thermoplastic polymer which is not polypropylene, a decorative layer arranged thereupon and a heat-cured layer applied to the decorative layer,

• wherein a decorative layer and a heat-cured layer applied to the decorative layer are present on each side of the backing layer;
• wherein the heat-cured layer arranged on the decorative layer is composed of a thermosetting polymeric material crosslinked by exposure to pressure or heat during the production of the layered composite;
• wherein the total thickness of the layered composite is from 1 to 20 mm and whose backing layer makes up at least 80% of the thickness;
• wherein said reinforced thermoplastic polymer comprises polyethylene, polyvinyl chloride, polyesters, polycarbonates, polyacrylates, polymethacrylates, polyamide, polyurethane, a polyacetal and/or polystyrenes,
• and which layered composite is prepared by
• heating said reinforced thermoplastic polymer to at least 180° C. in an extruder;
• then, under a pressure of at least 80 N/cm2, introducing said heated reinforced thermoplastic polymer into an injection molding chamber of an injection molding machine into which the films for the decorative layer and the heat cured layers and an optional intermediate layer have previously been placed,
• applying to the layers in the injection-molding machine a holding pressure of at least 10 N/cm2,
• while maintaining said pressure, cooling to a temperature not below 60° C. for a period of not more than 4 minutes, and then
• removing the layered composite from the injection-molding chamber.
