A decorative, high pressure, conductive laminate for flooring material is formed of a plurality of phenolic impregnated carbon-containing core sheets, a melamine resin impregnated decor sheet containing about 3-5% carbon fibers having a length greater than 1/16 inch and preferably 1/8 inch or more, and a melamine resin impregnated abrasion resistant overlay. The overlay melamine resin also contains an ionic salt and a tertiary aliphatic amine, both also preferably being in the decor melamine as well. The laminate has a volume resistance of 2.5.times.10.sup.4 to about 10.sup.6 ohms. To make the product more dimensionally stable, carbon containing core sheets are interleaved with non-carbon-containing kraft sheets, the phenolic resin of which also contains ionic salt.
