ABSTRACT:
A high-contrast room-light-handleable black-and-white silver halide photographic element that is especially useful in the field of graphic arts is comprised of a support, an imaging layer containing doped silver halide grains with a mean grain size of less than 0.12 micrometers, and a print-out layer containing doped silver halide grains with a mean grain size in the range of from 0.14 to 0.4 micrometers. The element utilizes very slow speed emulsions which render it capable of being handled in room light and is able to print-out a visible image on normal exposure and develop to full density upon being processed in conventional developing solutions.
