Abstract
(EN) There is provided a method of coating a substrate comprising at least one chemical group, by contacting the substrate surface with a compound comprising at least one carbon-carbon double bond or a mixture of a first monomer M1 and a second monomer M2. Then a reaction is initiated to form a covalent bond by reaction of the photoactive groups 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 photoactive group. The method is to a large extent resistant to inhibition of impurities in the substrate surface. A greater uniformity of the elastic modulus throughout the substrate and the added layers can be achieved. When a further topcoat is added resulting surface has a high hardness, and the scratch resistance is improved. When a topsheet is applied the abrasion resistance is improved.
(FR) L'invention concerne un procédé de revêtement d'un substrat comprenant au moins un groupe chimique, par mise en contact de la surface du substrat avec un composé comprenant au moins une double liaison carbone-carbone ou un mélange d'un premier monomère M1 et d'un deuxième monomère M2. Une réaction est ensuite initiée pour former une liaison covalente par réaction des groupes photoactifs et de la double liaison carbone-carbone, en soumettant au moins une partie des complexes formés à un rayonnement actinique, la longueur d'onde du rayonnement actinique étant adaptée pour être absorbée par le groupe photoactif. Le procédé est, dans une large mesure, résistant à l'inhibition des impuretés dans la surface du substrat. Une plus grande uniformité du module élastique à travers le substrat et les couches ajoutées peut être obtenue. Lorsqu'une couche de finition supplémentaire est ajoutée, la surface obtenue présente une dureté élevée et la résistance aux rayures est améliorée. Lorsqu'une feuille supérieure est appliquée, la résistance à l'abrasion est améliorée.
