Abstract
A surface covering has a base to which is laminated a rigid vinyl film. The film is precoated with an electron beam cured wearlayer. The preferred wearlayer composition is a polymerizable organic urethane-polyester wearlayer coating. The coated printed film is prepared by application of a polyester urethane acrylate composition to a printed sheet of rigid vinyl film and the coating is exposed to a low accelerating energy Electro-curtain to form an abrasion resistant topcoat with no apparent degradation of printed rigid vinyl film.

A process of making a surface covering comprising the steps of:
- providing a sheet of vinyl film material,
- coating the sheet with a wear layer composition comprising a cross-linkable organic moiety, and
- exposing the wear layer composition to electron beam radiation at an energy level less than that imparted by a 135 KeV field with a 2.75 inch average gap under conditions sufficient to cure the wearlayer and from a mechanically embossable wearlayer having a moiety conversion of greater than 85% adjacent the wearlayer/film interface.

- coating the sheet with a wearlayer composition comprising a cross-linkable organic moiety, and
- exposing the wearlayer composition to electron beam radiation at an energy level less than that imparted by a 135 KeV field with a 2.75 inch average gap under conditions sufficient to cure the wearlayer and form a mechanically embossable wearlayer having a double bond conversion of greater than 85% adjacent the wearlayer/film interface.
A composite surface covering component comprising:
- a mechanically embossable wearlayer comprising an electron beam radiation cured composition including a cross-linked organic moiety;
- and
- a film comprising a vinyl composition, wherein the wearlayer composition has a moiety conversion of greater than 85% adjacent the wearlayer/film interface.
