Abstract

Investment procedure to produce a color image on a photo-exposed photographic element, element that carries on its base a number of layers of silver halide emulsions sensitive to different regions of the visible spectrum, inversion procedure that includes the steps to produce an image of negative silver in at least one of said layers of emulsions by developing in a photographic developer of black and white images followed by at least one reversal re-exposure of the silver halide previously unexposed and revealing in a photographic developer of color in the presence of a color-forming coupler, after said re-exposure and development in a color developer comprising embedding said photographic element in an aqueous solution containing a nucleating agent of a boron compound and a developing agent. , 4-dihydroxybenzene which carries a side chain containing at least 4 carbon atoms, of 1,4-dihydroxybenzene that said side chain makes indifusible whereby it is confined to a greater degree to the outer layer of said layers of emulsions with respect to said base, said nucleating agent of the boron compound nucleating almost all of the silver halide previously not exposed and said 1,4-dihydroxybenzene compound revealing to metallic silver essentially only the silver halide previously not exposed in said outer emulsion layer.
