ABSTRACT:
A heat developable light-sensitive material having both (a) a light-sensitive element which contains at least one light-sensitive silver halide emulsion layer and at least one image forming substance capable of forming a diffusible dye and (b) a dye fixing element capable of fixing the formed diffusible dye on the same side of one support, in such relation that a diffusible dye may permeate the dye fixing element (b) by diffusing from the light-sensitive element (a).
The light-sensitive material of the present invention has a simple structure and does not require complicated procedures for its use or excess structural elements. Photographic images can be formed using the light-sensitive material in a short period of time by means of a simple photographic treatment.
