ABSTRACT:
According to the present invention there is provided a method for preparing a silver salt diffusion transfer imaging element comprising the steps of coating in the order given on a grained and anodized side of an aluminum support (i) an image receiving layer containing physical development nuclei, (ii) a photosensitive layer containing a silver halide emulsion being in water permeable relationship with said image receiving layer and (iii) optionally an antistress layer being in water permeable relationship with said image receiving layer, said aluminum support before being coated with a silver halide emulsion layer being guided over rollers, characterized in that at least 90% of said rollers has an electrical resistance lower than 10.sup.9 ohm.
