摘要： A direct positive silver halide material is disclosed. The material is comprised of a support base having a silver halide emulsion layer thereon which contains at least one phenazine series compound represented by the general formula (I), (II) or (III) and at least one compound represented by the general formula (IV), (V) or (VI). The structural formulae are shown within the specification wherein their substituents are defined. By including one compound of each of these groups within the material the resulting material provides images with a reduced minimum density without reducing the contrast of the images formed.

摘要： A silver halide light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer is disclosed. The emulsion layer contains a silver halide prepared in the presence of a tetrasubstituted thiourea as a silver halide solvent and was hardened with a hardener containing a vinylsulfonyl group. Combined use of the tetrasubstituted thiourea and the hardener of the above-described kinds increases the storability of the light-sensitive material.
