Abstract
A polymer composition including polymer particles containing a first polymer and a second polymer is disclosed. The first polymer has a crosslinked core and has a glass transition temperature in the range of −30° C. to 100° C. The second polymer containing select crosslinking groups and has a glass transition temperature in the range of −10° C. to less than 18° C. A process to prepare the polymer composition is provided. Also provided are a coated article containing a coating prepared from the polymer composition and a method of preparing the coated article. The polymer composition has good low temperature film formation and provides a film with an acceptable level of hardness.
