Abstract
First, a decorative sheet is produced by forming in sequence on a base paper such as titanium paper an ordinary printed layer and a heat-foamable printed layer, respectively with desired patterns. The decorative sheet is then impregnated with a thermosetting resin liquid and dried. The dried impregnated decorative sheet is superposed on a substrate such as a core sheet, and the resulting laminated structure is sandwiched between a pair of heating plates and heated and pressed whereby a thermoset integral structure with the pattern of the foamable printed layer foamed is produced. The entire surface of the integral structure is coated with a solvent to swell the foamed pattern layer and then rubbed to remove the swollen foamed pattern layer and form concavities thereat. The resulting thermoset resin decorative sheet or plate is provided with deep distinct concavities coincident with the pattern of the heat-foamable printed layer as well as a good surface luster.
