Abstract

A method for the decorative coating of sheet-like materials, particularly laminated plastics and wood-derived panels is disclosed to achieve a marbled decor effect by pressing a support sheet, impregnated with a curable aminoplast resin and coateed with a thermoplastic or duroplastic synthetic resin, on the substrate to be coated at the melting or curing temperatures of the resins, in which PA0 (a) a support sheet is used which has two superimposed layers of a transparent, thermoplastic or duroplastic synthetic resin, which flows well under the pressing conditions, the layer facing the support sheet containing a flake or scale-like pigment in an amount of 2 to 40% by weight of the synthetic resin and the outer layer of synthetic resin being devoid of such pigments and PA0 (b) the pressing is carried out in a compression mold or tool, which has no surface profiling. The invention furthermore is directed to the synthetic resin-containing support sheets used in the inventive method. The coated materials have a marbled surface and are suitable particularly for the manufacture of doors, furniture, table tops, facade elements, exhibition booths or for the decoration of rooms, such s foye…
