    • 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, 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, and a third set of doped silver halide grains with a mean grain size of less than 0.12 micrometers distributed within the print-out layer or within a separate safelight protection layer. Dopant levels are controlled so that the photographic speed of the imaging layer is higher than the photographic speed of the print-out layer and so that the photographic speed of the third set of silver halide grains is less than that of the imaging layer. 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.
