1. A coating composition for forming an elastic barrier coating, the coating composition comprising:
an aqueous carrier medium;
at least a first polymer comprising: (i) a barrier segment comprising aromatic groups and urethane linkages, urea linkages, or a combination thereof, having a glass transition temperature of greater than 0° C.; and (ii) an elastomeric segment that is different from (i) having a glass transition temperature of less than 0° C., wherein the barrier segment comprises at least 30 weight % of the polymer based on the total solids weight of the polymer; and
polymeric core-shell particles dispersed in the aqueous carrier medium.
