NOVELTY - At least partially applying (M1) a first metal on surface of a substrate involves: applying a coating by treating the substrate in plasma, where the plasma comprises at least one compound selected from up to ten carbon alkanes, and unsaturated monomers; producing polymers of carboxylic groups and adsorbed ions of at least one second metal on the surface of the substrate, reducing the ions to second metal and depositing step.    USE - For at least partially applying a first metal on the surface of a substrate; in an object selected from circuit, printed wire board, antenna intended for radio frequent electromagnetic waves, antenna for telecommunication, fuel cell, solar cell, light reflector or automotive light reflector (claimed). The substrate includes glass or SiO2.    ADVANTAGE - The material sensitive to for instance low pH or solvents can be coated. Substrates including glass, SiO2 with very few of no abstractable hydrogen atoms as well as polymer materials containing halogen atoms can be coated with good adhesion. The method provides an improved method which improves the adhesion and which allows a wider range of substrates to be coated with good adhesion. The substrates such as polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) which are sensitive to for instance low pH/high pH or other properties of the solutions used can be coated with metal, because the applied thin coating of plasma-polymerized material acts as a protective barrier. A further advantage is that substrates with very few (epoxy resins) of no abstractable hydrogen atoms can be coated, since the applied thin coating of plasma-polymerized material has abstractable hydrogen atoms. Also polymer materials containing halogen atoms like bromine which partly deactivate the grafting process can be used. A further advantage is that inorganic materials including glass, SiO2 can be used a substrate and successfully coated.    DETAILED DESCRIPTION - Method (M1) for at least partially applying a first metal on the surface of a substrate involves: applying a coating by treating the substrate in a plasma, where the plasma comprises at least one compound selected from up to 10C alkanes, and unsaturated monomers; producing polymers on the surface of the substrate, where the polymers comprises carboxylic groups and adsorbed ions of at least one second metal, reducing the ions to the second metal or producing polymers on the surface of the substrate, where the polymers comprises carboxylic groups, bringing the surface of the substrate in contact with at least one dispersion of colloidal metal particles of at least one second metal, where the particles have a diameter of 5-500 nm, and depositing the first metal on the second metal. An INDEPENDENT CLAIM is included for an object comprising a substrate manufactured by the method (M1).
