Surface covering and process for its manufacture

摘要

A vinyl film is precoated with an electron beam cured wearlayer. The preferred wearlayer composition is a polymerizable organic urethane-polyester wearlayer coating. The preferred 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.
