A process for making a panel-like structure constructed to be mounted in an automobile vehicle to form a part of the interior thereof. According to this process, an outer layer (26) defining at least a portion of the exposed exterior surface of the structure is prepared by applying a water-dispersed thermoplastic polyurethane composition and a heat-activated reactive cross-linking monomer onto a mold surface and thereafter drying the composition. Next, a rapidly reacting composition is sprayed onto an inner surface of the outer layer while the outer layer is retained on the mold surface to form a polyurethane elastomer inner layer (28) that is interfacially chemically bonded to the outer layer. The inner layer with the outer layer interfacially chemically bonded thereto is then united with the rigid substrate (22) so that the rigid substrate serves to reinforce the outer layer. The exposed exterior surface of the panel-like structure simulates the appearance and feel of authentic leather, while the inner layer and an optional semi-rigid polyurethane cellular foam intermediate layer (44) provide a compressing feel to the exposed portion of the outer layer. |
