Summary: | There is provided a method of coating a substrate comprising at least one secondary amine, by contacting the substrate surface with a compound comprising at least one carbon-carbon double bond, wherein an electron withdrawing group is on at least one side of the carbon-carbon double bond, so that a complex is formed between nitrogen in the secondary amine and the carbon-carbon double bond. Then a reaction is initiated to form a covalent bond by reaction of nitrogen in the secondary amine and the carbon-carbon double bond, by subjecting at least a part of the formed complexes to actinic radiation, wherein the wavelength of the actinic radiation is adapted to be absorbed by the complex. When a further top-coat is added, the resulting surface has a high hardness, and the scratch resistance is improved. |
