Abstract
A heat-developable photosensitive material includes an infrared-sensitive layer having a maximum spectral sensitivity at a wavelength of 700 nm or longer. A silver chlorobromide emulsion from which the infrared-sensitive layer is formed is prepared by adding an iodide at an intermediate stage during silver halide grain formation or later. The photosensitive material exhibits high sensitivity and low fog while the corresponding emulsion coating composition in solution form remains stable with time.
