1. A water-based coating composition comprising a film-forming binder resin;
composite particles including one or more waxes and a metal oxide selected from the group consisting of zinc oxide, magnesium oxide, and silver oxide, wherein the composite particles are present in the water-based coating composition at a concentration of about 10 to about 25 1b/gallon;
a pigment present in an amount of about 3 to about 60 PVC; and
wherein the composite particles are discrete particles that include the one or more waxes on an outer surface thereof of the metal oxide.
