Copper in the form of a chelate compound is embedded in a resin compound. The copper is activated by thermally decomposing the organic copper compound by means of a laser beam that generates the conductor pattern in the organic phase. In an example, the glass fiber fabric is fed through a bath to be coated with epoxy resin. After preliminary drying at moderate temperatures in a drying tower, the coated fabric is fed through a further bath containing an organic copper compound, such as copper diphenyl, dissolved in the epoxy base material. In a further drying step, the organic phase is stabilized and preliminarily polymerized.
