The present invention provides an imaging element comprising on a support in the order given (i) a base layer comprising a binder in an amount between 1 and 3 g/m<2>, (ii) a photosensitive layer comprising a spectrally sensitised silver halide emulsion, said emulsion consisting principally of silver chloride but containing bromide ranging from 0.1 mole % to 40 mole % and iodide ranging from 0 to 2 mole % and (iii) a receiving layer containing physical development nuclei in water permeable relationship with said photosensitive layer, characterized in that the ratio by weight of gelatin to silver halide (expressed as an equivalent amount of AgNO3) in said photosensitive layer is at least 1.35 .
