An aqueous polymer blend composition including a predominant amount of soft polymer
particles and a minor amount of hard polymer particles is provided. The soft polymer
particles contain, as copolymerized units, 70 to 99.7% by weight monoethylenically
unsaturated (meth)acrylic monomer and from 0.3 to 10% by weight monoethylenically
unsaturated acid monomer, based on weight of soft polymer particles. The soft polymer
particles are made by a select process including redox polymerization or polymerization
in the presence of excess unreacted monomer. The aqueous polymer blend composition
is useful for preparing dry coatings having improved dirt pickup resistance and
acceptable scrub resistance. A method is provided for preparing a dry coating from
the aqueous polymer blend composition.
