Abstract

PURPOSE: To subject an internal latent image type silver halide emulsion to surface development in the presence of a foggant and form a reversal positive image having superior spectral sensitivity, high maximum density, and a sufficiently low minimum density, by adding a specific sensitizing dye and a specified compound in combination to the title emulsion.
