Abstract
Abstract Coating compositions which contain a mildew controlling amount of an isothiazolone are stabilized against chemical decomposition of the isothiazolone by the addition of a metallic compound. Among the compounds which can be used are the acetates, carbonates, chlorides, bromides, nitrates, sulfates, phosphates, and oxides of cadmium, cobalt, copper, lead, manganese, mercury, nickel, silver and zinc.

Claim 1
Independent Claim
153 words
A coating composition which comprises an aqueous dispersion of a vinyl or acrylic emulsion polymer having a pH greater than 9.0, a mildew-controlling amount of an isothiazolone of the formula ##STR4## wherein Y is a hydrogen atom, a (C 1 -C 18 ) alkyl group, a (C 6 -C 10 ) aryl group, or a (C 7 -C 10 ) aralkyl group; R is a hydrogen atom, a halogen atom, or a (C 1 -C 4 ) alkyl group, R' is a hydrogen atom, a halogen atom, or a (C 1 -C 4 ) alkyl group, or R and R' can be taken together to complete a benzene ring, optionally substituted with one or more halogen atoms, nitro groups, (C 1 -C 4 ) alkyl groups, cyano groups, or (C 1 -C 4 ) alkoxy groups, and a stabilizing amount of a metallic compound of zinc, molybdenum, copper (cuprous, cupric), lead or mercury.
Claim 2
Dependent Claim
