A method is disclosed for applying an antibacterial coating onto a substrate having one or more layers of print. In a printing press, one or more layers of print are applied to a substrate in a printing step. A finishing composition is applied over the layers of ink by a finishing stage in a finishing step to form a continuous outer protective layer. The finishing composition is applied to the substrate by a roller. The printing step and the finishing step are performed simultaneously. The finishing composition includes an antibacterial additive.

Compositions and methods for making biocidal currency are disclosed. The compositions of the within invention contain biocidal silver or silver compounds, which include elemental silver, nanoparticulate silver, colloidal silver, inorganic silver, including silver oxide, silver compounds and silver salts, that exhibit antibacterial and/or antiviral properties. Ink formulations that are used in the printing of currency, such as offset printing and intaglio printing, which incorporate the biocidal silver are also disclosed. In addition, the biocidal silver is formulated within pulp mixtures during the currency paper or linen-making processes. Methods of employing the biocidal silver or silver compounds of this invention include high pressure engravement printing where the silver impregnates the fiber, being cellulosic fiber, cotton or linen, forming a permanent biocidal layer within or on the surface of the currency, and offset printing.

A filter media having lignite-derived activated carbon, polyacrylic acid (PAA), a commercially available copper-zinc alloy, and polydiallyldimethylammonium chloride (PolyDADMAC) or Luviquat®, which is Poly[(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)], combined and used as suitable replacement for TOG bituminous coal-based activated carbon, silver, and PolyDADMAC. Functional groups in lignite-based activated carbon interact with the polyacrylic acid. Functional groups such as calcium, iron, or aluminum oxide/hydroxide of lignite-based activated carbon interact with PAA, and help hold the PolyDADMAC in place. The additional presence of a copper-zinc alloy enhances the filter anti-microbiological performance.
