Japanese Patent JP2519920
Kind Code:
B2
Abstract:
An image is formed by imagewise exposing a heat-developable photosensitive material comprising (a) a photosensitive silver halide, (b) a reducing agent or a precursor thereof, (c) a dye-providing substance which forms or releases a diffusible dye in proportion or counter-proportion to the reduction of the silver halide into silver, and (d) a binder on a support, during or after the imagewise exposure of the photosensitive material, maintaining the photosensitive material in such a pH and a temperature lower than the heat-developing temperature for a predetermined time that the reaction between the silver halide and the reducing agent preferentially takes place rather than the reaction of forming or releasing a diffusible dye, and thereafter heat developing the exposed material in the presence of a base and/or a base precursor to imagewise produce a diffusible dye.
