Abstract
A surface covering is a laminate including a hard inorganic wear layer deposited on a support by a reduced pressure environment technique such as ion assisted physical vapor deposition. The support may be selected from metal foils, films or sheets and plastics, rubbers or mineral/binder systems. The preferred support materials include organic materials. The wear layer is between 1 micron and 25 microns in thickness and has a CIE LAB value of total Delta E of less than 12. Preferably, the wear layer is deposited on the support at a temperature of less than 175.degree. C.
