Disclosed is a coating composition comprising a resinous binder prepared from a reaction mixture comprising (a) a first component; (b) a second component; and (c) a third component comprising a block copolymer having (i) a first block comprising units having functional groups reactive with at least one of the first and second components and (ii) a second block comprising units having functional groups that promote adhesion to a polymeric substrate, provided that the first component, the second component, and the block copolymer differ from each other. The block copolymer may also be used as an additive in a coating composition.
