ABSTRACT:
The present invention provides an imaging element comprising on a support in the order given a base layer containing a matting agent having a number average diameter between 0.4 and 1 times the thickness of said base layer, a spectrally sensitized silver halide emulsion layer and a receiving layer containing physical development nuclei having an average diameter less than 6 nm and wherein the number of nuclei having a diameter larger than 4.5 nm is less than 15% of the total number of nuclei contained in said receiving layer and wherein substantially no matting agent is present in said receiving layer, silver halide emulsion layer or any other layer optionally being present between said receiving layer and silver halide emulsion layer.
