Latest Patents
Otomo's latest patents focus on methods for processing silver halide-containing photosensitive materials. One of his key inventions involves a method that includes a silver-removing step where silver formed during the color developing process is oxidized by a bleaching agent. This silver is then transformed into a soluble silver complex through the action of a fixing agent. The process is designed to be more efficient than conventional methods, utilizing both a bleaching bath and a bleach-fixing bath. The time for processing in the bleaching bath is intentionally shorter than that of traditional methods, leading to a more streamlined workflow. The use of a ferric aminopolycarboxylic acid complex and thiosulfate as bleaching and fixing agents, respectively, further enhances the effectiveness of this innovative approach.
