Latest Patents

One of his latest patents is focused on tabular grain silver halide emulsions and a method for their preparation. This photosensitive emulsion comprises a dispersing medium and silver halide grains containing at least 80 mole percent bromide. Notably, at least 50% of the projected area of these grains is accounted for by tabular grains free of twin planes, which have {100} parallel major faces. The emulsion is chemically sensitized and exhibits a reciprocity failure of less than 35 sensitivity units between exposures of 10^-5 seconds and 100 seconds. This emulsion can be utilized as a latent image forming emulsion in photographic elements. The preparation process involves a nucleation step and a physical ripening step, ensuring optimal conditions for the emulsion's effectiveness.
