ABSTRACT:
The present invention provides an imaging element comprising in the order given (i) a hydrophilic base, (ii) an image receiving layer containing physical development nuclei and (iii) a photosensitive layer containing a silver halide emulsion being in water permeable relationship with said image receiving layer, characterized in that said photosensitive layer or another optional layer being in water permeable relationship therewith contains at least one gelatin species whereof a 10% by weight aqueous solution at 36.degree. C. and pH 6 has a viscosity lower than 20 mPa.s at a shearing rate of 1000 s.sup.-1.
