ABSTRACT:
A process is described in which a cast coated high gloss polymeric coating is formed on a sheet substrate by applying an aqueous emulsion or dispersion of polymeric material to the substrate, forming a continuous film of the polymeric material in the presence of water by heating without pressure to a temperature above the film forming temperature of the polymeric material, and moulding the film under high pressure at a temperature greater than 100.degree.C. The process is capable of being operated in such a manner as to give a high gloss coating that has a gloss and smoothness as good as or better than that obtainable by cast coating of mineral pigment.
