摘要： There are disclosed an internal latent image type direct positive light-sensitive emulsions having improved spectral sensitization performance, and chemical sensitization performance, and color diffusion transfer photographic film units in which said emulsions are used. The emulsions are prepared by subjecting a silver halide grain, which forms an internal nucleus, to chemical sensitization, in the presence of an organic silver halide solvent, and adding a solid adsorbing agent, before finishing the formation of an outer shell silver halide phase, to remove a part or all of the silver halide solvent, wherein the emulsions may further contain a tabular silver halide grain having an average grain diameter of at least 0.3 .mu.m and a ratio of an average grain diameter to an average grain thickness of 2 or more, based on 50% or more of the total silver halide grains.

摘要： A silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a spectrally sensitized silver halide emulsion layer and a non-light-sensitive layer provided on a support. According to the present invention, the silver halide emulsion layer or the non-light-sensitive layer contains a complex of Ni, Co, Mn or Zn with a nitrogen-containing heterocyclic compound represented by the following formula: ##STR1## wherein ##STR2## Y is CR.sup.3 or N; Z is CR.sup.4 or N; each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently is hydrogen, a halogen atom, hydroxyl, amino, hydroxyamino, cyano, an alkyl group, an aryl group, an alkylthio group, an alkylamino group, an arylamino group, an alkoxycarbonyl group or an acylamino group; R.sup.1 and R.sup.2 with X and Cx may form benzene ring or a six-membered nitrogen-containing heterocyclic ring; and the benzene ring or the six-membered nitrogen-containing heterocyclic ring may be substituted with a halogen atom, hydroxyl, amino, hydroxyamino, cyano, an alkyl group, an aryl group, an alkylthio group, an alkylamino group, an arylamino group, an alkoxycarbonyl group or an acylamino group.
