Abstract: A process for producing conductor lines for electrical circuits, which process enables high packing density of the conductor lines and is adaptable to a large number of different conductors and support materials. The process comprises producing a powder image of a conductor line pattern by means of a preferably photographically prepared, positive, tacky pattern on an intermediate support; removing the tacky pattern, and transferring the powder image onto a final support, the powder image being consolidated into a conductor line pattern either before or after the transfer by sintering.
