Abstract: In the production of a decorative sheet, a synthetic resin paste is first applied onto the upper surface of a substrate sheet to form an undercoat layer. Then, one or more pastes, each being of the same material and having approximately the same viscosity as the paste of the undercoat layer, are laterally sprayed so as to drop onto the undercoat layer. The result is a smoothing phenomenon, with the pattern layer cooperating with the undercoat layer to form a smooth patterned surface. Finally, the pattern layer is heated and jelled.

Abstract: Decorative panels are prepared employing a support of a transparent material having one of its faces dulled to enhance adhesion of a lacquer thereon. The processes also include applying a layer of a volatile liquid carrier containing metal and/or metal oxide particles. Also applied is a lacquer that is not miscible with the volatile liquid carrier. In one of the embodiments, the liquid carrier thrusts back the lacquer forming holes in the lacquer to reach the dulled surface of the support and adhere thereto. In the resultant panel, the particles are visible through the thickness of the transparent support at locations corresponding to the holes in the lacquer.
