Abstract: A three-ply product includes a particleboard core assembled with a patterned vulcanized fibre sheet or layer on each surface. One of the vulcanized fibre sheets may have a preprinted decorative pattern provided thereon. The other vulcanized fibre sheet may also be decorative, or merely a plain sheet of vulcanized fibre. The product is useful for woodworking applications, and may be processed (i.e., stained, sanded, lacquered, etc.) like a natural wood product. Unlike prior vulcanized fibre processes, the process of making the vulcanized fibre sheets preprints a pattern, in a preprinting process, on the top sheets of cellulose paper plies.
