ABSTRACT:
A thermodevelopable photographic material is described, comprising a support, at least one photographic silver halide emulsion layer coated thereon, and a dye donating substance capable of forming or releasing a mobile dye in response to, or in inverse response to, the reduction of silver halide in said emulsion to silver by heating, wherein the color of an image formed by the fixing of each of said mobile dyes released by exposure and heating to a dye fixing layer is within the range of a*=10 to -18 and b*=10 to -18 determined from tristimulus values in the 10 degree visual field XYZ system under standard light C.
