Disclosed is a resinous adhesion promoter comprising (a) a random copolymer having first and second constitutional monomeric units, the first units comprising halogen and/or a pendant organic group having six or more carbon atoms and the second monomeric units comprising an active hydrogen-containing functional group; and (b) one of either (i) a non-reactive adhesion promoter or (ii) a reaction mixture comprising a first component and a second component, at least one of the first and second components having functional groups being reactive with the active hydrogen-containing functional groups of the random copolymer.

Plastic substrate adhesion promoter with random copolymer

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.
