A two-component clearcoat composition contains a first component comprising a hydroxyl-functional resin; and a second component comprising a crosslinking agent which is a first isocyanate resin which is unblocked; wherein at least one of the first component and the second component further comprises a blocked isocyanate resin which is a reacted form of a second isocyanate resin and a blocking agent; and wherein the first isocyanate resin and the second isocyanate resin are capable of reacting with the hydroxyl-functional resin to form a crosslinked coating. A substrate coated with the clearcoat composition exhibits improved visual appearance to the coated substrate, such as reduced orange peel and an increased balance value.
