PCT No. PCT/AT95/00190 Sec. 371 Date Aug. 19, 1996 Sec. 102(e) Date Aug. 19, 1996 PCT Filed Oct. 4, 1995 PCT Pub. No. WO96/11118 PCT Pub. Date Apr. 18, 1996The invention concerns a plastics-paper composite which substantially consists of a paper layer, a polypropylene layer and a polyester layer, the polyester layer forming one of the two surface layers of the plastics-paper composite. This plastics-paper composite is used to produce weatherproof laminated sheets with surface protection, an acrylate layer being applied to the polyester layer of the plastics-paper composite. This composite is stacked on one or both sides with a plurality of papers impregnated with synthetic resin to form a stack, the acrylate layer lying against the outermost paper layer(s). This stack is then pressed at high pressure and high temperature. For use, the surface protection is removed from the acrylate layer as from the polyester layer.
