(i) a polymeric binder component comprising a plurality of ester functional groups; (ii) a plurality of core-shell polymeric particles, wherein the core comprises a polymer of an organic biocide and one or more ethylenically unsaturated monomers, at least one of which is a hydroxyl, carboxylic acid, ether , sulfonic acid, amino or amido; wherein the polymer comprises greater than 30% by weight of monomeric residues comprising polar groups; and a polymer of at least one ethylenically unsaturated monomer, wherein the polymeric dispersant comprises residues of ethylenically unsaturated monomers comprising a polar group selected from hydroxyl, carboxylic acid, ether, sulfonic acid, amino or amido. A shell polymer dispersant comprising less than 20% by weight of; and (iii) optionally an additional biocide. |
