Beschreibung
Zusammenfassung:	A press plate for producing decorative laminate from resin impregnated paper, with alumina particles on its pressing surface, is coated with diborides selected from the group consisting of hafnium diboride, molybdenum diboride, tantalum diboride, titanium diboride, tungsten diboride, vanadium diboride, or zirconium diboride or mixtures thereof for making the press plate resistant to scratching using a process wherein the press plate and the sputtering head are moved relative to one another to provide a scanning speed sufficient to give a thermal gradient in the press plate of 50° F. or less, to provide reduced built-in stress and more delocalized heat distribution throughout the press plate.
