Claim 11:
12. An antimicrobial coating composition comprising (i) a polymer emulsion and (ii) from 20 ppm to 6000 ppm, by dry weight based on total dry weight of the coating composition, a silver, wherein the polymer emulsion comprises a copolymer including, as polymerized units, (a) ethylenically unsaturated nonionic monomers, and (b) from 0.01% to 2%, by dry weight based on total dry weight of the polymer emulsion, heterocyclic group-containing monomers and wherein the mole ratio of heterocyclic groups in the heterocyclic group-containing monomers to silver is at least 4, wherein the polymer of the polymer emulsion further comprises, as polymerized units, by dry weight based on total dry weight of the polymer emulsion, (c) from 0.01% to 5%, stabilizer monomers.
