ABSTRACT
Tanned leather is usually coated with a thin pigmented or lacquer coating. One of the purposes of such a coating is decorative. The coating may also change some physical properties of leather: it may decrease water and air permeability, increase its rigidity, etc. Such changes depend on the coating type, especially on the polymer used as a film former. The properties also depend on coating formation technology: the coating may penetrate deeply into leather, or it may remain only on the surface. The coating technology chosen depends on the leather structure and the degree of its surface damage.
