Abstract
The present invention relates to a coating composition containing a polymer blend dispersion including: a first polymer having a relatively low molecular weight and a relatively low glass transition temperature and comprising a self-crosslinking monomer; and a second polymer having a relatively high molecular weight and a relatively high glass transition temperature. Latex paint compositions and architectural coatings containing the coating composition according to the invention are also described herein, as well as substrates coated therewith.
