There is provided a novel marble-translucent thin resilient decorative sheet 1, which comprises thin permeable pulp paper 2, fine whitish inorganic filler powder, and a substantially transparent cured resin contained by impregnation throughout the pulp paper, said filler powder being uniformly deposited onto at least the top surface of the pulp paper and being firmly fixed thereto. The decorative sheet is produced by impregnating fine whitish inorganic filler-loaded permeable pulp paper with a liquid polymerizable resinous composition for forming a substantially transparent cured resin, placing the impregnated pulp paper between molding plates, and polymerizing the resinous composition into a cured resin; or by impregnating permeable non-loaded pulp paper containing no filler powder with the liquid resinous composition containing fine whitish inorganic filler powder and carrying out the polymerization between molding plates as described above.
A marble-translucent resilient decorative sheet, said resilient decorate sheet having a thickness in the range of about 0.1 mm to 5 mm and comprising a layer of permeable pulp paper, a substantially transparent cured resin impregnated throughout the pulp paper, and a fine, substantially white inorganic filler powder uniformly deposited onto at least one surface of the pulp paper and being firmly fixed thereto, whereby the decorative sheet is provided with a deep marble-translucent tone by the synergistic effect of both the filler powder and the pulp paper impregnated with the cured resin.
