1. A method for improving the dirt pick-up resistance of a dried coating
formed from a coalescent-free aqueous coating composition comprising
forming said coalescent-free coating composition, said composition
comprising an aqueous emulsion-polymerized polymeric binder having a glass
transition temperature from about –15 ºC to about +15 ºC, said binder comprising
from about 2% to about 20%, by weight based on the weight of said polymeric
binder, of at least one copolymerized ethylenically-unsaturated active methylene
monomer [emphasis added];
applying said coating composition to an indoor or outdoor architectural
