ABSTRACT:
A leather-like sheet material bearing a remarkable resemblance to high-quality leathers of natural origin, especially in respect of flatness, bending crimp, grain and feeling, is produced by providing a substrate consisting of a fibrous base material and a porous coating layer with a thin layer of a polymer, subjecting the surface to a specific heat treatment, providing the resulting material with another thin layer of a polymer, and, if desired, embossing the material.
