FOTOGRAFISKT ELEMENT INNEFATTANDE KEMISKT OCH SPEKTRALT SENSIBILISERADE SKIVFORMADE SILVERHALOGENIDKORN

摘要

High aspect ratio chemically and spectrally sensitized tabular grain silver halide emulsions, photographic elements incorporating these emulsions, and processes for the use of the photographic elements are disclosed. In the tabular grain emulsions the silver halide grains having a thickness of less than 0.3 micron and a diameter of at least 0.6 micron have a high aspect ratio and account for at least 50 percent of the total projected area of the silver halide grains present.
