1. A method of making an antimicrobial article, comprising:
- applying a silver composition to a substrate to provide a liquid coated substrate, the silver composition comprising a silver salt other than silver sulfate in a solvent, the silver composition comprising a stabilizing agent in an amount less than about 100 ppm;
the substrate comprising material selected from the group consisting of polyamide, polyester, polyacetate, polyacrylic, polyolefin, polyurethane, polyvinylchloride, polyvinyl alcohol, polycarbonate, polyvinylpyrrolidone, polylactic acid, ethylene-vinyl acetate, polystyrene, cellulose acetate, polyacrylate, polyacrylamide, polyacrylonitrile, polyvinylidene difluoride, polytetrafluoroethylene, polyoxymethylene, polyvinyl ether, styrene-ethylenebutylene-styrene elastomer, styrene-butylene-styrene elastomer, styrene-isoprene-styrene elastomer, glass fiber, ceramic and combinations of two or more of the foregoing; and
drying the liquid coated substrate to provide a color stable antimicrobial article comprising silver salt applied to the substrate.
