The disclosure relates to a coating composition comprising a component A comprising one or more acrylic polymers having one or more chemically crosslinkable functional groups X selected from hydroxyl, thiol, isocyanate, epoxy, acid, thioisocyanate, acetoacetoxy, carboxyl, amine, anhydride, ketimine, aldimine, or urethane group; and a component B comprising one or more monomers or oligomers having one or more functional groups Y that react with the functional groups X to form a crosslink and one or more radiation crosslinkable functional groups D which are radiation crosslinkable ethylenically unsaturated double bonds; wherein said functional groups X and Y are pair-wise selected from hydroxyl and isocyanate groups, thiol and isocyanate groups, epoxy and acid groups, epoxy and isocyanate groups, isocyanate and amine groups, or isocyanate and urethane groups. This disclosure is also directed to a method of using said coating composition to coat a substrate including a vehicle, a vehicle body or parts thereof.
