Abstract
The process for producing a surface covering having a randomly embossed wear surface which comprises incorporating a blowing agent into a resinous composition, forming the resinous composition into a layer, heating to partially fuse the layer, printing a design on the surface of the layer, randomly distributing flakes of resinous composition containing an inhibitor for the blowing agent onto the printed surface of the layer, applying a clear wear layer thereto and heating the assembly to the decomposition temperature of the blowing agent.
