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, characterized in that said element before and/or after being coated with said image-receiving layer and before being coated with another layer is wetted with a fluidum with a conductivity of at least 1 .mu.S/cm at 25.degree. C. and then the wetted element is brought in contact with an earthed discharging means and dried before coating the following layer.
