A coating composition includes: a polymer prepared from a reaction mixture including: a hydroxyl functional prepolymer comprising a reaction product of a prepolymer mixture and a non-aromatic anhydride. The polymer includes at least two functional groups selected from hydroxyl groups, carboxyl groups and combinations thereof. The polymer includes 10-40 weight % of structural units derived from benzoic acid or substituted benzoic acid and greater than 15 weight % of structural units derived from a polyol having at least three hydroxyl groups based on the total weight of the polymer. A substrate at least partially coated with a coating composition and a method of preparing a coating composition are also disclosed.
