    摘要: An aqueous polymeric composition including an emulsion polymer including, as copolymerized units, from 0.5% to 25%, by weight based on the weight of the polymer, carbonyl-functional ethylenically-unsaturated monomer, and an autoxidizable material having less than 10%, by weight based on the weight of fatty acid residues therein, tri-unsaturated fatty acid residues; wherein the autoxidizable material is from 8% to 35% of the total weight of the polymer and the autoxidizable material; and wherein the polymeric composition is free from copolymerized-carbonyl-functional-monomer-reactive amine and hydrazine functional groups is provided. An aqueous coating composition including the aqueous polymeric composition, a method for improving the repaintability of an aqueous coating during drying, and a method for providing a coating are also provided.
