ABSTRACT:
In the development of exposed light-sensitive reproduction layers using an aqueous electrolyte developer the parts of the layer corresponding to the non-image areas are removed by electrochemical treatment. An electrolyte is used which has a pH in the range from 2.0 to 10.0 and contains at least one salt in a concentration of 0.1 weight percent up to the saturation limit of the solution for the particular salt. The electrolyte may also contain 0.1 to 5 weight percent surfactant.
