The composite article including the elastomeric layer and the decal may then be demolded from the mold. Alternatively, a paint composition is applied into the mold cavity to form a paint layer over the decal. The polyurethane elastomer composition is applied into the mold cavity to form an elastomeric backing layer over the paint layer. The composite article including the paint layer, the decal, and the elastomeric backing layer may then be demolded from the mold. The composite article may be a seat for an all-terrain vehicle.
