PCT No. PCT/AT95/00113 Sec. 371 Date Jan. 26, 1996 Sec. 102(e) Date Jan. 26, 1996 PCT Filed Jun. 1, 1995 PCT Pub. No. WO95/32771 PCT Pub. Date Dec. 7, 1995A continuous process is disclosed for producing a strip of decorated ski coating material from ultra-high molecular weight polyethylene. A 0.5 to 1.5 mm thick strip of ski coating material produced in a screw-type or piston-type extruding machine or by sintering followed by peeling and printed with thermodiffusion dyes continuously runs through a heating zone in which it is uniformly heated up to a temperature above 140 DEG C., so that the crystalline structure of the ultra-high molecular weight polyethylene is partially decomposed and the thermodiffusion dye diffuses into the molten ski coating material without the need for an intermediate carrier. The ski coating material provided with the thermodiffusion dye then runs through a cooling zone in which it is uniformly cooled down to a temperature equal to or lower than ambient temperature, so that 25% to 60% of the ultra-high molecular weight polyethylene crystallizes and the thermodiffusion dye is fixed on the ultra-high molecular weight polyethylene during cooling.
