ABSTRACT:
A method is described for forming a black-and-white photographic image consisting essentially of a silver image and a coextensive dye image, in which the maximum density of the image and the fastness of the image to light are greatly improved, by processing a silver halide photosensitive material which contains silver halide in a reduced amount (compared with conventional materials) that has been imagewise exposed to light in the presence of a naphthalene compound containing at least two hydroxy substituents groups on the nucleus thereof and a p-phenylenediamine type developing agent or a precursor of the p-phenylenediamine compound.
