Abstract
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. The preferred diborides are titanium and zirconium. The most preferred diboride is titanium. The color, gloss and surface appearance of laminate pressed with a titanium diboride coated press plate is substantially the same as laminate pressed with the press plate before coating.
