Abstract: The present invention provides aqueous compositions for use in coating wood joinery, especially for exterior use, comprising (a) one or more dihydrazide compounds in a total amount of from 0.5 to 4 wt. %, based on the total weight of composition solids and (b) of one or more aqueous multistage emulsion copolymers containing, as (i) a first stage, an emulsion copolymer having a glass transition temperature (Tg) via differential scanning calorimetry (DSC) of from −50 to 30° C., and containing, in copolymerized form one or more monoethylenically unsaturated phosphorous acid monomers and, one or more keto group containing amide monomers, and, as (ii) a second stage, an emulsion copolymer having a DSC Tg of at least 50° C. to 125° C., wherein the weight ratio of (i) the first stage to (ii) the second stage, based on copolymer solids, ranging from 50:50 to 90:10.
