DUENNES, BIEGSAMES BLATT MIT EINER MARMORDURCHSCHEINENDEN DEKORATION UND VERFAHREN ZU SEINER HERSTELLUNG.

摘要

There is provided a novel marble-translucent thin resilient decorative sheet 1, which comprises thin permeable pulp paper 2, fine whitish inorganic filler powder, a substantially transparent cured resin contained by impregnation throughout the pulp paper and, optionally, a thinner resin surface layer 3 on the resin-filled pulp paper layer; 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 polymerisable resinous composition for forming a substantially transparent cured resin, placing the impregnated pulp paper between molding plates, and polymerising 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 polymerisation between molding plates as described above.
