DECORATIVE SYNTHETIC RESIN SHEETS HAVING THREE- DIMENSIONAL PATTERN FOR WALLS, CEILING OR FURNITURE AND PROCESS FOR MANUFACTURING SAME

摘要

A decorative synthetic resin sheet formed on its surface with a three-dimensional multi-colored pattern including distinct protuberances and depressions with a marked difference in elevation therebetween. The sheet has a smooth planar rear surface which ensures good adhesion to the desired surface, The sheet is made by a process comprising a first step of coating one surface of a thin base sheet of paper or like material with a main synthetic resin composition containing a blowing agent, drying the resulting coating layer by heating and thereafter delustering the surface of the coating layer with a suitable solvent; a second step of fully foaming the coating layer by heating, then stabilizing the foamed layer by cooling and subsequently preheating only the surface of the foamed layer; a third step of hot-embossing the preheated foamed layer and cooling the embossed surface; and a fourth step of applying a synthetic resin composition containing a coloring agent only to the raised top surface of the resulting embossed pattern and cooling the sheet.
