Latest Patents

Inoue's latest patents include a negative-working type silver halide photographic material. This innovative material comprises a support with at least one light-sensitive silver halide emulsion layer containing a hydrazine derivative. The emulsion layer or another hydrophilic colloidal layer on the support contains at least one redox compound capable of releasing a development inhibitor upon oxidation. Notably, the silver halide emulsion consists of monodispersed silver halide grains comprising 50 mol % or more of silver chloride. Another patent focuses on a silver halide photographic material for a photomechanical process. This material features a support with at least one light-sensitive silver halide emulsion layer and at least one light-insensitive upper layer. The light-sensitive upper layer has a greater melting time than the emulsion layer, and the emulsion layer contains starch, modified starch, and/or macromolecular polysaccharides produced from starch using a microbial fermentation process. This innovation has greatly improved reduction processability.
