A coated panel formed from a self-supporting cellulosic substrate and a top coating containing a thermoset resin having about 0.1-1.5 wt % free formaldehyde admixed with said resin; and (b) a thermoplastic polymer thoroughly admixed with said resin, wherein said thermoplastic polymer exhibits amine groups capable of reacting with at least some of the free formaldehyde under resin curing conditions. The coated panel can be embossed with decorative patterns such as wood grain without fracture of the coated surface or significant buildup on the press or embossing die surfaces.
