Method for the formation of direct positive color images

Abstract

A method for the formation of direct positive color images wherein after image-wise exposure of a direct positive color photosensitive material which comprises at least one internal latent image type silver halide emulsion layer which has not been pre-fogged and color image forming couplers on a support, the material is subjected to development after and/or during a fogging process, the development process being carried out using a development bath which contains at least one N-hydroxylalkyl substituted p-phenylenediamine derivative in the presence of at least one compound of general formula [I] and/or [II] as indicated below: ##STR1## wherein Q represents the group of atoms required to form a five- or six-membered heterocyclic ring, which heterocyclic ring may be condensed with a carbon aromatic ring or a heterocyclic aromatic ring, Y represents a divalent linking group consisting of at least one atom selected from the group consisting of, carbon atom, nitrogen atom, oxygen atom, sulfur atom, and R represents an organic group which includes at least one thioether group, amino group, ammonium group, ether group or heterocyclic group, n represents 0 or 1, m represents 0, 1 or 2, M represents a hydrogen atom, alkali metal atom, ammonium group or a group which is cleaved under alkaline conditions; ##STR2## wherein Q' represents the group of atoms required to form a five or six membered heterocyclic ring which can form imino silver, Y, R, n and M are the same as those in general formula [I], and m' represents 1 or 2.
