Disclosed is an aqueous coating compositionncomprising: (a) water, (b) a base medium, (c) anpyrithione salt, in an amount of from 0.01% to 2.0%nbased upon the weight of the composition, and (d)nzinc oxide compound selected from the many gradesnsuitable for paint manufacture at a concentration ofnfrom 0.001% to 10% based upon the weight of thencoating composition. Also disclosed is an aqueousnantimicrobial coating composition, characterized bynantimildew efficacy and protected againstndiscoloration attributable to the presence ofnpyrithione therein, said composition being selectednfrom the group consisting of water-based paints,nadhesives, caulks and sealants, and combinationsnthereof, said composition comprising water, anpyrithione salt or acid, an organic base medium andna zinc compound, said zinc ion being present in saidncomposition in an amount of from 0.001% to 10% basednupon the weight of the coating composition. |
