Claim 0:
1. 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 having, 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, (iii) one or more pigment, one or more extender, or both one or more pigment and one or more extender, at a pigment volume concentration of 10 to 75%, and optionally, a surfactant,
wherein, excluding the optional surfactant, there is only one polymer in the composition.
