ABSTRACT:
Silver halide photographic elements which are capable of high-contrast development and are especially useful in the field of graphic arts comprise surface latent image forming high-chloride silver halide grains and have incorporated therein a hydrazine compound which functions as a nucleator, an amino compound which functions as an incorporated booster, and a benzimidazolocarbocyanine sensitizing dye that provides enhanced photographic sensitivity yet leaves substantially no sensitizing dye stain after rapid access processing.
