the invention consists of a multilayer material and a process for manufacturing this material . the multilayer material comprises a polyester substrate which is provided with a thermoset plastic polymer coating and a layer of contact adhesive . the polymer coating is produced by a reaction between a polyurethane polymer containing hydroxyl groups and a low molecular linear polyisocyanate , with catalytic tin - organic additives and colorants . the multilayer material is resistant to tearing and is also weather - resistant . a transparent , reactive layer , consisting , for example of a layer to take toner or ink , or a metallic layer , can be deposited on the side opposite to the polymer - coated substrate . multilayer materials of this kind are suitable for large - scale covering of supporting frameworks in the construction of model aircraft and are also suitable as a medium onto which images and print may be applied using a plain paper copier , and can also be used to carry advertising .
