Abstract
An abrasion resistant laminate includes a substrate and a durable wear-resistant top layer assembly laminated over a top side of the substrate. The layer assembly includes a wear-resistant upper layer and an underlying decorative layer which together include a first paper sheet impregnated with a first resin. The top layer assembly further includes a core layer underlying the decorative layer. The core layer includes second and third paper sheets impregnated with a second resin. A fourth paper sheet is interposed between the second and third paper sheets in the core layer. The fourth paper sheet is impregnated with the first resin, whereby the fourth paper sheet functions as a balance sheet to equalize expansion and contraction of the layers under the influence of environmental factors.
