Optical barrier compositions are provided that allow the production of thin solid surfacings without the problem of having visual characteristics of the substrate visible through the thin surfacing. The optical barriers are filled thermoplastic which inhibit at least 90% of light transmitted therethrough at a thickness between about 1 and about 50 mils. The optical barriers are designed to be interposed between the substrate and a decorative overlay which is either transparent or translucent.
