    摘要： The present invention discloses a method for producing an article comprising a substrate and a coloured abrasion resistant coating present on at least part of a surface of the substrate, the method comprising providing a substrate comprising a metallic element and/or an alloy of a metallic element, and/or a polymer; providing a first compound comprising a functional group R 1 selected from the group consisting of C 1 -C 20 alkyl, C 1 -C 20 cycloalkyl, C 1 -C 10 aryl and epoxy, and optionally comprises at least one halogen atom, and a second compound comprising a cross-linkable functional group selected from the group consisting of a (meth)acrylate, an ester, a mercapto, a vinyl, and a (meth)acrylated urethane; hydrolysing the first and the second compound; condensing the hydrolysed first and second compound, thereby obtaining a pre-polymer; adding a colorant to the pre-polymer; applying the pre-polymer to at least part of a surface of the substrate; and inducing cross-linking of the cross-linkable functional group by exposing the pre-polymer to one or more of a temperature up to 250 °C, UV radiation or IR radiation, thereby obtaining an article comprising a substrate and a coloured abrasion resistant coating covering at least part of a surface of the substrate; the coloured abrasion resistant coating being a cross-linked inorganic organic hybrid coating comprising at least one functional group R 1 , and the cross-linked inorganic organic hybrid coating being covalently bonded to the substrate.
