The invention relates to a method for producing an electrically conductive structure, in particular a conducting track, on a non-conductive substrate material, which contains an additive (1) having at least one metal compound. For this purpose, the substrate material is irradiated by means of a laser in order to selectively activate the metal compounds, for example inorganic metal compounds, contained in the additive (1). The metal seeds formed by the activation are then metallized in order to create the electrically conductive structure on the substrate material. Because the additive (1) is provided with an in particular full-surface coating before the additive is introduced into the substrate material, such that the additive (1) is reduced and the coating is oxidized by the laser activation, the reaction partners necessary for the required chemical reaction with the additive (1) are provided by the coating. Because of the thereby significantly reduced interaction with the substrate material, the limitation to certain plastics or plastic groups also is lifted. |
