PURPOSE:To pattern efficiently and accurately decorative sheets and to obtain the sheet with a good finish by coating paste on the part not to be patterned of the surface of a coated noncombustible sheet, then thermally spraying the part to be patterned with a metal, and removing the paste. CONSTITUTION:The surface of a noncombustible sheet 1 is thermally sprayed with a metal which is appropriately selected to obtain a layer 2. Printing paste is then coated on the whole surface of the coated layer 2 except the part 3 to be patterned. After the printing paste 4 is dried, a metal 5 in a color different from that of the substrative metal is thermally sprayed on the coated layer 2 to pattern the plate. The noncombustible plate 1 is subsequently immersed into a hot-water vessel to soak the paste in the hot water, and the paste is removed by a jet of high-temp. and high-pressure water. The patterning can be carried out accurately and surely in this way, and the decorativesheet with a good finish can be manufactured.
