Abstract: Production of laminated articles by casting and drying a layer of a fully-reacted polyurethane material on a release treated carrier in a manner to form a moisture vapor-permeable and moisture-impermeable film, one or more hides of split leather being bonded to the supported film through a moisture vaporpermeable tie-coat of a compatible adhesive, and the carrier then being removed. The resultant split leather/polyurethane film product has the appearance and other properties of top-grain leather.
