    Abstract: A method of antibacterial and antiviral surface treatment of flexible cover sheet materials, comprising at least the steps of providing a flexible cover sheet substrate (S), selected from hides and skins, depositing at least one lower support layer (2, 2I 2II, 2III) on the upper surface of the substrate (S), providing an antibacterial and antiviral formulation comprising a liquid active sanitizing composition dispersed in a solvent containing a polymer-based solution, depositing the formulation on at least one lower support layer (2, 2I, 2II, 2III) to form an upper antibacterial and antiviral active layer (1, 1I, 1II, 1III), heating the cover substrate (S) to cause evaporation of the solvent of an upper active layer (1, 1I, 1II, 1III). The active sanitizing composition contains silver chloride and solid-state titanium dioxide of nanometric size and the active sanitizing composition ranges from 0.1 % to 2.5% by weight, the solvent ranges from 8% to 80% by weight, and the polymer-based solution ranges from 15% to 80% by weight based on the total weight (100%) of the formulation, depending on the use to which the ) treated cover substrate (S) is intended, to inhibit proliferation of bacterial and viral pathogens on the surface of the substrate (S), while keeping the properties of the materials thereof unaltered.
