ABSTRACT:
A heat-developable light-sensitive material comprising a support having there on a light-sensitive silver halide, a binder and a dye releasing compound which is capable of reducing the light-sensitive silver halide and reacting with the light-sensitive silver halide by heating to release a dye, said dye releasing compound is changed so as to have shorter absorption wavelength. The heat-developable light-sensitive material has high sensitivity and can be developed without supplying water from the outside.
