Abstract (en)
[origin: EP0450637A2] A direct positive color image forming method is disclosed. The method comprises: imagewise exposing to light a photographic photosensitive material comprising at least one non-pre-fogged internal latent image type silver halide emulsion layer which is provided on a support and contains a magenta coupler; subjecting the photosensitive material to a fogging treatment; and simultaneously or thereafter developing the photosensitive material. The magenta coupler is a compound having the formula (I). <CHEM> in which R<1> is hydrogen or a substituent group; X is hydrogen or a group which can be eliminated by a coupling reaction with an oxidation product of an aromatic primary amine developing agent; and each of Za, Zb and Zc is -CH- , <CHEM> (R<2> is hydrogen or a substituent group), =N-or -NH-.
