Abstract
Abstract A process for forming an image which comprises heating a light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder and a dye releasing redox compound which is reductive to the light-sensitive silver halide and capable of releasing a hydrophilic dye upon reaction with the light-sensitive silver halide by heating, after imagewise exposure or simultaneously with imagewise exposure, in a substantially water-free condition in the presence of a compound represented by the formula (A): ##STR1## wherein R 1 represents a hydrogen atom or a monovalent or divalent aliphatic group; R 2 and R 3 , which may be the same or different from each other, each represents a hydrogen atom, an aliphatic group or an aromatic group; R 1 and R 2 may be taken together to form a heterocyclic ring; R 2 and R 3 may be taken together to form a heterocyclic ring; and n represents 1 or 2, to imagewise form a mobile dye is disclosed.
