Preferably, the dressing consists of two layers, the inner layer, which is adjacent the leather and completely receives the protruding fibres, is formed of the aqueous dispersion of synthetic plastics material and the outer layer, which has the structured surface, consists of an aqueous dispersion of synthetic plastics material or of a liquid solution of synthetic plastics material.
