  • Patent number: 6548428
    Abstract: 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.
