An article including a panel-like structure mountable in an automobile vehicle to form a part of the interior thereof, and a process for making the same are disclosed. According to this process, an outer layer defining at least a portion of the exposed exterior surface of the structure is prepared by applying a water-dispersed composition containing a thermoplastic polyurethane and a heat-activated crosslinking agent onto a mold surface and thereafter drying the composition. Next, a composition comprising (i) a poly(vinyl chloride) resin and at least one plasticizer and/or (ii) a thermoplastic polyurethane resin material is gelled onto an inner surface of the outer layer while on the outer layer is retained on the mold surface. The gelled composition is then fused to form an inner layer interfacially chemically bonded to the outer layer. The inner layer with the outer layer chemically bonded thereto is united with the rigid substrate 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 provide a compressing feel to the exposed portion.
