Title: Aqueous dispersions, coating compositions formed with aqueous dispersions, and multi-layer coatings

Abstract

An aqueous dispersion includes an aqueous medium and self-crosslinkable core-shell particles dispersed in the aqueous medium. The core-shell particles include (1) a polymeric core at least partially encapsulated by (2) a polymeric shell having urethane linkages, keto and/or aldo functional groups, and hydrazide functional groups. Further, the polymeric core is covalently bonded to at least a portion of the polymeric shell.
