A coating composition includes: an aqueous medium; a first polymer comprising first core-shell particles dispersed in the aqueous medium, where the first core-shell particles include (i) keto and/or aldo functional groups, (ii) a polymeric shell including carboxylic acid functional groups and urethane and/or urea linkages, and (iii) a polymeric core at least partially encapsulated by the polymeric shell, where the polymeric shell and/or the polymeric core include the keto and/or aldo functional groups; a second polymer dispersed in the aqueous medium, the second polymer including carboxylic acid functional groups and hydroxyl functional groups; a first crosslinker including a polyhydrazide reactive with the first core-shell particles; and a second crosslinker reactive with the first core-shell particles and/or the second polymer, where the polymeric core of the first core-shell particles are covalently bonded to at least a portion of the corresponding polymeric shell.
