Conductive tracks are formed on a support by providing a coated support where the coating is susceptible to forming a latent image upon pressure-exposure (e.g. a coating of a silver halide emulsion in gelatin), pressure exposing said coated support according to a desired track pattern to form a latent image of the track pattern and developing the latent image to form a conductive metal track pattern corresponding to the latent image. The latent image may be formed, for example, by applying pressure using a stylus or scalpel, an engraved stamp or a roller carrying a relief pattern. The method is capable of forming conductive tracks at very high resolution (e.g. 10 mum or less), optionally on a flexible support. |
