  • Patent number: 3930921
    Abstract: An improved method of finishing leather by transferring a finish coating, at least the outer stratum of which comprises a thermoplastic, adhesive acrylic polymer, from a release layer bearing the finish coating to the leather. The leather to be coated (which may be supported on an appropriate backing layer) and the release layer are pressed into a sandwich-like assembly with the concurrent application of sufficient heat and pressure to transfer substantially the entire finish coating to the surfaces of the leather and the backing layer juxtaposed therewith. Transfer of the finish coating is effected without the application of any adhesive material or "tie coat" prior to pressing the coating into contact with the leather, by virtue of the thermoplastic, adhesive characteristics of the acrylic finish coating per se.The method may be carried out batch-wise employing discrete backing and release layers for the transfer of finish coatings to individual leather pieces.
