The present invention is directed to a coating composition that when applied over untreated thermoplastic and thermosetting resinous substrates, produces an adherent coating thereon. The composition includes a crosslinkable component and a crosslinking component. The crosslinkable component includes a polymeric mix containing at least one crosslinkable copolymer polymerized from a monomer mixture comprising one or more ethylenically unsaturated monomers having on average 1 to 10, preferably 1 to 4 and more preferably 1 to 2 hydroxyl groups and a saturated hydrocarbon polymer. The crosslinkable component includes one or more cycloaliphatic polyisocyanate of the formula:R1—(R2—NCO)n
