<p>Selectivity embossed surface coverings are prepared by mechanically embossing a wear layer which overlays at least one printing ink containing a photoinitiator which has been printed in a pattern or design. The embossed wear layer is subjected to ultraviolet radiation which causes curing of the wear layer in the surface areas disposed over the printing ink. The product then is fused whereby the mechanical embossing in surface areas which are not disposed over the printing ink relaxes and becomes smooth. In a variant of the invention, a thermoplastic wear layer is employed which can be mechanically embossed in the surface areas which are not disposed over the printing ink with a texture different from the first applied mechanical embossing. In another variant, two different spectral regions of UV curing radiation are used so that a urethane coating can be employed as a top coat with a selectively embossed surface.</p> |
