Abstract:
A thermally developable photosensitive material comprising a support and an image-forming layer disposed on one surface of the support, the image-forming layer containing a non-photosensitive organic silver salt, a photosensitive silver halide, a reducing agent for reducing silver ions, a binder and a compound represented by the following formula (I), wherein after the material is image-wise exposed and thermally developed at 121Â° C. for 24 seconds, at least 90% of the developed silver is in contact with the photosensitive silver halide grains after development;(X&Parenclosest;k&Parenopenst;L&Parenclosest;m&Parenopenst;Aâ€”B)nâ€ƒâ€ƒFormula (I) wherein: X represents a silver halide-adsorbing group or light-absorbing group having at least one atom of N, S, P, Se and Te; L represents a (k+n)-valent linking group having at least one atom of C, N, S and O; A represents an electron-donating group, B represents a leaving group or a hydrogen atom, and after the compound represented by formula (I) is oxidized, (Aâ€”B) is eliminated, or eliminated and further deprotonated to form a radical Aâ€²; and k falls between 0 and 3; m represents 0 or 1; n represents 1 or 2, but m=0 when k=0 and n=1.
