    • The invention relates to a silver-based antibacterial agent containing an inorganic carrier characterised by bacteriostatic and even biocidal activity for a wide variaty of micro-organisms, especially polymers, water dilutable and solvent systems as well as organic systems, and can be characterised in that it contains from 1.10exp(-6) to 7.2 wt.% of colloidal metal silver and from 1.33 . 10exp(-6) to 15.67 wt.% of at least one silver halogenide selected from the group containing chloride, bromide, silver iodide. Residual 100 wt.% contains an inorganic carrier of micro particles having granularity from 0.1 to 30 micrometers of at least one compound selected from the group containing aluminium oxide, silicon dioxide, titanium dioxide, aluminium hydroxide, carbonates and binary magnesium, calcium and barium carbonates; aluminosilicates and binary lithium, sodium, potassium, magnesium, calsium and barium aluminosilicates. The total molar ratio of the halogenides content and silver content in both the forms ranges between from 1.10exp(-6) to 1 gram molecules. The antibacterial agent may further contain the following binding components with the granularity from 0.1 to 30 micrometers and in the amount within the range 0.5 - 40 wt.% of at least one compound selected from the group containing phosphates, hydrophosphates, diphosphates, dihydrophosphates; sodium, potassium, calcium and magnesium phosphoranes; as well as lime hydrate and magnesium hydroxide.
